JP 2012-18605 A

  However, the conventional support system displays all the information about the faulty device uniformly. Therefore, a CE (Customer Engineer) that deals with a failure needs to separate information about a device that the user wants to deal with and information about a device that does not, and this reduces work efficiency. In addition, when a plurality of workers each having a portable terminal work simultaneously, the same information is transmitted to all portable terminals, resulting in a waste of communication charges.

  In one aspect, an object of the present invention is to provide a device information display method, a device information storage device, and a computer program in consideration of the position of a mobile terminal.

  In one proposal, a device information display method includes: a device information storage device that stores device information about a maintenance target device; and a device that stores the device information and a location storage server that stores a position of the device information storage device or the maintenance target device. In a device information display method for displaying device information transmitted to a portable communication device having an imaging unit and a display unit and received by the portable communication device on the display unit based on the notification, the device information storage device includes the portable communication device. A notification of approach to the device itself or the maintenance target device is received from the location storage server, the device information stored in the storage unit is read, the read device information is transmitted to the portable communication device, and the portable communication device The device information is received, an image of the device corresponding to the received device information is acquired by the imaging unit, and the acquired image and the received device information are displayed on the display unit.

  Next, a table managed by the x device 1 will be described. FIG. 5 is an explanatory diagram showing an example of a record layout of the device information table 16a. This table stores information (apparatus information) about an apparatus corresponding to the x apparatus 1 (hereinafter referred to as “corresponding apparatus”, “server computer 5” in the present embodiment). The device information table 16a includes a date / time field, a product name field, a serial number. Column, position column, status column, and message column. The date / time column stores the date / time when the record was created. The product name column stores the product name of the corresponding device. Serial No. The column stores the serial number of the corresponding device. The position column stores position coordinates in the data center of the own device. The status column stores the status of the corresponding device. The message column stores an error message to be transmitted to the mobile terminal 2.

And a composite primary key consisting of two product names. Note that the position coordinates are not the position coordinates of the x apparatus 1, but the position coordinates of the corresponding apparatus may be stored. In that case, the positional relationship between the x device 1 and the corresponding device is obtained in advance. Using this positional relationship, the position coordinates transmitted from the x apparatus 1 may be corrected to obtain the position coordinates of the corresponding apparatus.

  FIG. 8 is an explanatory diagram showing an example of the record layout of the permitted device table 35c. The permitted device table 35c is a table that stores information about devices that the location management server 3 permits or does not permit. Mainly, information about a device carried by a CE who enters a data center to deal with a failure is stored. The permitted device table 35c includes a device name column, an application name column, a serial column, a permission / non-permission column, and a device position column. The device name column stores the name of the device. The application name column stores the name of the application used on the device. The serial column stores the serial number of the device.

The primary key of the permitted device table 35c is serial. Alternatively, it may be a composite primary key composed of a serial and an application name. In the former case, connection of the device is permitted if the serial numbers match. In the latter case, not only the serial number but also the matching application used for connection is requested. The application name column may store an abbreviation of the application name.

  FIG. 9 is a flowchart showing the business flow of the CE. The CE activates the application of the portable terminal 2 possessed by arriving at the data center (step S71). The application to be activated is an application for exchanging information with the x device 1 and the position management server 3. This is an application having a name described in the application name column of the permitted device table 35c of the location management server 3. The CE performs initial setting according to the data center (step S72). For example, setting for connecting to a wireless access point installed in the data center, setting of the location management server 3, IP address setting or acquisition, and the like. Authentication by the location management server 3 and communication confirmation with the x device 1 and the y device 4 are also included.

  The CE goes to the rack where the server computer 5 in which the failure has occurred is installed. When the target rack is reached, the server computer 5 is imaged by the imaging unit 25 of the portable terminal 2. When the server computer 5 in which the failure has occurred is photographed, a message indicating the failure content is displayed, so the CE confirms the failure content (step S73). The CE deals with the failure according to the confirmed failure content (step S74). The CE confirms whether or not the failure has been recovered (step S75). Specifically, the server computer 5 that has dealt with is imaged again by the imaging unit 25 of the mobile terminal 3, and it is confirmed that a message regarding the failure is not displayed. If the server computer 5 that has been dealt with has been recovered (YES in step S75), it is confirmed whether another failure has occurred (step S76). This is because a failure has occurred in a plurality of server computers 5 or a new failure has occurred due to a side effect of coping. Specifically, the addressed server computer 5 is photographed by the imaging unit 25 and whether a message is displayed or not, and another server computer 5 is photographed by the imaging unit 25 to check whether or not the message is displayed. . If no other failure has occurred (NO in step S76), the CE creates a report (step S77). Thereafter, the handling is terminated.

  If the server computer 5 that has dealt with has not been recovered (NO in step S75), or if another failure has occurred (YES in step S76), a countermeasure is taken (step S74). The subsequent processing (after step S74) is as described above.

  In the present specification, as described above, the function of displaying information related to an object in the image on the image captured by the imaging unit 25 of the mobile terminal 2 is referred to as an “air tag function”. As an example in this specification, it is to display the failure information regarding the server computer 5 so as to be superimposed on the image of the server computer 5 captured by the imaging unit 25.

  Next, processing performed by the x device 1 will be described. FIG. 10 is a flowchart showing an operation procedure when the x device 1 is activated. The CPU 11 of the x device 1 reads the position information of the own device stored in the mass storage device 16 (step S1). The CPU 11 determines whether the position information has been acquired from the mass storage device 16, that is, whether the position information has been stored (step S2). When position information is not stored (NO in step S2), the CPU 11 inquires of the position management server 3 about the position of the own apparatus (step S3). The CPU 11 determines whether or not a position has been acquired from the position management server 3 (step S4). When the position is acquired (YES in step S4), the CPU 11 ends the process. When the CPU 11 inquires of the position management server 3 about the position of the own apparatus, the CPU 11 transmits the product name and serial number of the corresponding apparatus to the position management server 3 as keys. This is because the position of the corresponding apparatus such as the server computer 5 is stored in the apparatus position table 35a of the position management server 3. When the device position table 35a manages the position of the x device 1, the product name and serial number of the x device 1 may be used as keys.

When the position is not acquired from the position management server 3 (NO in step S4), the CPU 11 receives position information (coordinate values) from the y device 4 via the wireless communication unit 15 (step S6). In the data center, the y device 4 is installed so that radio waves can be received from a plurality of y devices 4 at the same time. The CPU 11 causes the wireless communication unit 15 to measure the radio field intensity received from the plurality of y devices 4, and obtains the result (step S7). The CPU 11 calculates the estimated distance between the device itself and the y device 4 from the radio wave intensity. Based on the estimated distance and the position information of the y device 4, the position of the own device is calculated based on the principle of triangulation (step S8). The CPU 11 stores position information in which the calculated position is associated with the current date and time in the mass storage device 16 (step S9). The CPU 11 transmits the position information (position coordinates, product name of corresponding device, serial number) to the position management server 3 (step S10). The CPU 11 ends the process.
Although the x device 1 receives coordinate values from the y device 4, the present invention is not limited to this. The ID of the y device 4 and the position coordinate value of the y device 4 may be stored in advance in the mass storage device 16 of the x device 1, and the y device 4 may transmit the ID to the x device 1. In this case, the x device 1 may read the position coordinate value of the y device 4 from the mass storage device 16 based on the received ID. The calculation of the position is as described above. Furthermore, the transmission / reception relationship may be reversed. That is, the x device 1 transmits the ID to the y device 4. Each of the plurality of y devices 4 receiving the ID from the x device 1 transmits the ID and the radio wave intensity to the position management server 3. The position management server 3 calculates the position coordinates of the x device 1 from the ID and radio wave intensity of the x device 1 transmitted from the plurality of y devices 4. The position management server 3 may store the position coordinates in the apparatus position table 35 a and transmit the position coordinates to the x apparatus 1.

  When the position information is stored in the large-capacity storage device 16 (YES in step S2), the CPU 11 determines whether or not a predetermined number of days have passed since the date when the position information was stored (step S5). When the predetermined number of days have elapsed (YES in step S5), the CPU 11 executes step S6 and subsequent steps. When the predetermined number of days or more has not elapsed (NO in step S5), the CPU 11 transmits the position information to the position management server 3 (step S10), and the process ends.

  In the flowchart shown in FIG. 10, it is assumed that the x device 1 stores the position information of its own device in the mass storage device 16, but is not limited thereto. The x apparatus 1 may always calculate the position of the own apparatus at the time of activation. This is because the x device 1 is a device that is always in operation, and is often considered to be after the installation position has been changed together with the server computer 5 that is paired with the server device 5 as a pair. Further, when the location information is not stored, the location management server 3 is inquired, but the inquiry may not be performed. This is because the position information stored in the position management server 3 should not be adopted when the position information stored in the x apparatus 1 itself is a master and the position information stored in the position management server 3 is regarded as a slave. . In the case where the position information is stored, the position is calculated again when a predetermined number of days have elapsed since the stored date, but the present invention is not limited to this. Regardless of the number of days elapsed, position information that is always stored may be adopted. However, in this case, when changing the position of the x device 1, it is necessary to delete the position information stored in the mass storage device 16. Further, when the position information stored in the large-capacity storage device 16 is adopted, the position information is transmitted to the position management server 3 again. However, the position information may not be transmitted. That is, if NO in step S5, step S10 need not be executed. This is because when the stored position information is calculated, it should be transmitted to the position management server 3.

  FIG. 11 is a flowchart showing the monitoring processing procedure of the server computer 5 performed by the x device 1. The CPU 11 of the x device 1 determines whether the power of the paired server computer 5 is ON (step S21). If the x device 1 and the server computer 5 comply with a standard that regulates power supply such as USB, it can be determined by whether or not power is supplied from the server computer 5. When the server computer 5 is powered on (YES in step S21), the CPU 11 determines whether or not a failure has occurred in the server computer 5 (step S22). This determination is made with reference to the status column and message column of the device information table 16a. This is because when a failure occurs in the server computer 5, the firmware of the server computer 5 writes an error message in the message column to the effect that a failure has occurred in the status column of the device information table 16a. If a failure has occurred (YES in step S22), the CPU 11 determines whether the air tag function is valid (step S23). A flag variable indicating whether or not the air tag function is valid is stored in the large-capacity storage device 16, and the determination may be made based on the value of the flag variable. When the air tag function is valid (YES in step S23), the CPU 11 performs an interrupt setting (step S24). The CPU 11 sets an interrupt routine that is executed when a notification of the approach of the portable terminal 2 is received from the position management server 3. The CPU 11 notifies the location management server 3 of the content of the failure occurring in the server computer 5 that is a corresponding device. Specifically, the CPU 11 transmits the product name, serial number, status, and message of the server computer 5 to the location management server 3. The location management server 3 stores the transmitted content in the device information table 35b. The CPU 11 ends the process.

  If the power of the server computer 5 is OFF, that is, not ON (NO in step S21), the CPU 11 updates the device information stored in the device information table 16a (step S26). Specifically, the fact that the power of the server computer 5 is OFF is written in the device information table 16a. The CPU 11 masks the interrupt routine described above (step S27).

  When no failure has occurred in the server computer 5 (NO in step S22), the CPU 11 executes step S27 and ends the process.

When the air tag function is not effective (NO in step S23), the CPU 11 executes step S2.
7 is executed and the processing is terminated.

  FIG. 12 is a flowchart showing the procedure of the position monitoring process of the portable terminal 2 performed by the position management server 3. The process of FIG. 12 is a process executed every time a position is received from the mobile terminal 2 of the CE. The CPU 31 of the location management server 3 acquires the location of the mobile terminal 2 via the communication unit 36 (step S31). The CPU 31 checks the device information table 35b, reads the position coordinates of the device in which the failure has occurred (hereinafter referred to as “failed device”), and calculates the distance from the portable terminal 2 (step S32). The distance is calculated, for example, by calculating the difference between the position coordinates of the obstacle device and the position coordinates of the portable terminal 2 for each coordinate axis and obtaining the square root of the sum of squares of the differences.

  The CPU 31 compares the obtained distance value with a predetermined threshold value, and determines whether or not the mobile terminal 2 has come within a predetermined distance from the obstacle device (step S33). If the distance is within the predetermined distance (YES in step 33), the CPU 31 temporarily stores the serial number and product name of the faulty device in the storage unit such as the RAM 32 (step S34). The CPU 31 determines whether there is another faulty device (step S35). If there is no other faulty device (NO in step S35), the CPU 31 determines whether there is a serial number and product name stored in the storage unit such as the RAM 32 used when executing step S34 of the faulty device (step S36). ). If there is a stored serial number and product name (YES in step S36), the CPU 31 transmits the serial number and product name to the x device 1 (step S37). If there is no stored serial number or product name (NO in step S36), the CPU 31 ends the process. The serial number and product name are transmitted to all the x devices 1.

  If there is another faulty device (YES in step S35), the CPU 31 returns the process to step S32. The processing after step S32 is as described above.

  When the portable terminal 2 is not within the predetermined distance from the obstacle device (NO in step S33), the CPU 31 moves the process to step S35. The processing after step S35 is as described above.

  FIG. 13 is a flowchart illustrating a procedure of failure information transmission processing performed by the x device 1 in response to a notification from the location management server 3. This process is started when step S37 is executed in FIG. The CPU 11 of the x device 1 acquires the serial number and product name from the location management server 3 (step S41). The CPU 11 compares the acquired serial number and product name with the serial number and product name of the corresponding device, and determines whether or not the corresponding device is included (step S42). If the corresponding device is included (YES in step S42), the CPU 11 reads out the failure information (product name, serial number, position, state, message) from the device information table 16a (step S43). CPU11 transmits failure information to portable terminal 2 (Step S44). The CPU 11 ends the process. If no corresponding device is included (NO in step S42), the CPU 11 ends the process.

  In step S37 in FIG. 12, serial numbers and product names are transmitted to all the x devices 1, but the present invention is not limited to this. It is good also as transmitting only to the x apparatus 1 linked | related with the corresponding | compatible apparatus specified by a serial number and a product name. In that case, it is necessary to store the serial number and product name in association with the ID of the x device 1 in the device information table 35b. In such a case, the process of step S42 in FIG. 13 is not necessary.

  FIG. 14 is a flowchart illustrating a procedure of reception processing performed by the mobile terminal 2. The CPU 21 of the portable terminal 2 determines whether failure information has been received via the communication unit 26 (step S81). When the failure information is received (YES in step S81), the CPU 21 stores the failure information in the mass storage device 24 (step S82), and the CPU 21 ends the process. When the information other than the failure information is received (NO in step S81), the CPU 21 performs a process according to the content (step S83) and ends the process.

  The processing in FIG. 14 may be periodically executed by an interval timer or the like, or when the communication unit 26 receives data, the CPU 21 may be interrupted and executed each time.

  FIG. 15 is a flowchart showing a procedure of processing performed in the mobile terminal 2. CPU21 of the portable terminal 2 receives the positional information from the some y apparatus 4 via the communication part 26 (step S61). The CPU 21 measures the intensity of each radio wave received from the y device 4 (step S62). The CPU 21 calculates the position of its own device based on the principle of triangulation based on the position information received in step S61 and the radio wave intensity measured in step S62 (step S63). The CPU 21 transmits the calculated position information to the position management server 3 (step S64). The CPU 21 determines whether or not failure information is stored in the mass storage device 24 (step S65). When the failure information is stored (YES in step S65), the CPU 21 reads the position coordinates of the failure device from the failure information (step S66). CPU21 makes the attitude | position detection part 28 detect the attitude | position of an own terminal (step S67).

  The CPU 21 determines whether or not the CE is holding the portable terminal 2 over the obstacle device from the position calculated in step S63, the position of the obstacle device, and the attitude detected in step S67 (step S68). When it is determined that the user is holding the hand (YES in step S68), the CPU 21 displays the failure information on the display unit 27 (step S69). Since the fault device captured by the imaging unit 25 is displayed on the display unit 27, the CPU 21 recognizes the display position by image recognition and displays fault information on the display unit 27 so as to overlap the fault device. The display position of the faulty device in the display unit 27 may be estimated by the CPU 21 using the position of the own device, the position of the faulty device, and the posture of the own device.

  The CPU 21 determines whether there is other failure information to be displayed (step S70). If there is other failure information (YES in step S70), the CPU 21 returns the process to step S66. If there is no other failure information (NO in step S70), the CPU 21 ends the process.

  If the failure information is not stored (NO in step S65), or if the CE does not hold the mobile terminal 2 over the failure device (NO in step S68), has the CPU 21 displayed the failure information on the display unit 27? It is determined whether or not (step S71). If it has been displayed (YES in step S71), the CPU 21 hides the failure information (step S72). The CPU 21 moves the process to step S70. The processing after step S70 is as described above. When failure information is not displayed on the display unit 27 (NO in step S71), the CPU 21 moves the process to step S70.

  FIG. 16 is a flowchart showing the procedure of failure detection processing performed by the server computer 5. The CPU 51 (not shown) of the server computer 5 determines whether or not a failure has been detected (step S51). If detected (YES in step S51), the CPU 51 writes the device status and failure message in the device information table 16a of the corresponding x device 1 (step S52). The CPU 51 ends the process. If no failure is detected (NO in step S51), the CPU 51 does nothing and ends the process. The process shown in FIG. 16 is a process periodically executed on the firmware of the server computer 5.

  FIG. 17 is an explanatory diagram illustrating an example of a display screen of the mobile terminal 2. The screen shown in FIG. 17 is a case where no air tag is displayed. That is, the server A is operating normally and there is no failure information. FIG. 18 is an explanatory diagram illustrating an example of a display screen of the mobile terminal 2. The screen shown in FIG. 18 is a case where the air tag T is displayed. The air tag T includes a mark t1 indicating a state and a failure message t2. The mark t1 is changed in color and hatching depending on the state. For example, a yellow mark is used for warnings and a red mark is used for errors. The fault message t2 displays a fault status. In the example of FIG. 18, the server A is a server blade, the serial number is V12-3456, and a warning is given to the power supply unit. A more detailed failure point is the source unit n (#n) of the disk shelf (DE) uu number (#uu).

  FIG. 19 is an explanatory diagram showing an example of the air tag T. This is an example different from that shown in FIG. FIG. 19 shows that the device is shut down or the device is shut down while the air tag function is enabled.

As described above, Embodiment 1 has the following effects.
Since the CE displays the failure information related to the photographed failure device only when the portable device 2 photographs the failure device, the CE can easily identify the failure device. In addition, since no failure information is displayed for a device in which no failure has occurred, it is possible to easily check whether there is a failure in each device by photographing the device in the data center with the portable terminal 2. . Furthermore, even when a failure has occurred in a plurality of devices, only the failure information regarding the captured failure device is displayed on the mobile terminal 2, so the CE associates the failure device with the failure information. There is no need to do it. From the above, it is possible for the CE to leave the data center after easily confirming that no new failure has occurred after completion of the failure handling.

  Furthermore, by using this information system, CE can efficiently create reports to be submitted to customers. FIG. 20 is an explanatory diagram showing an example of a report creation screen. The status of each device shown in tabular form can be generated from the device information table 16a of the x device 1 or the device information table 35b of the location management server 3.

Embodiment 2
In the first embodiment, the location management server 3 notifies the x device 1 of the approach of the mobile terminal 2, but the x device 1 may poll the location management server 3. In the following description, differences from the first embodiment will be mainly described, and description of the same components as those in the first embodiment will be omitted.

  FIG. 21 is a flowchart showing the monitoring processing procedure of the server computer 5 performed by the x device 1. This corresponds to FIG. 11 of the first embodiment. In FIG. 21, processes similar to those in FIG. In FIG. 21, step S24 of FIG. 11 is step S28, and step S27 is step S29. Step S28 is processing for starting polling. The CPU 11 of the x device 1 sets a timer interrupt and sets the position management server 3 to poll every predetermined time (step S28). Step S29 masks the timer interrupt and stops polling.

  FIG. 22 is a flowchart showing the procedure of the mobile terminal location monitoring process performed by the location management server 3. This corresponds to FIG. 12 of the first embodiment. The CPU 31 of the location management server 3 acquires the location of the mobile terminal 2 (step S31). The CPU 31 updates the position of the portable terminal 2 stored in the permitted device table 35c with the acquired value (step S38). The CPU 31 ends the process.

  FIG. 23 is a flowchart showing a procedure of polling response processing performed by the location management server 3. This processing is performed by the location management server 3 when polled from the x device 1. The CPU 31 of the position management server 3 acquires position coordinates from the x device 1 (step S91). This position coordinate is the position coordinate of the x device 1 or the position coordinate of the corresponding device of the x device 1 (here, the server computer 5). The CPU 31 of the position management server 3 calculates the distance between the position represented by the received coordinates and the latest position of the permitted device (here, the portable terminal 2) stored in the permitted device table 35c (step S92). The CPU 31 determines whether the calculated distance is not a predetermined distance (step S93). If within the predetermined distance (YES in step S93), the CPU 31 temporarily stores the serial number of the permitted device in a storage area such as the RAM 32 (step S94). If not within the predetermined distance (NO in step S93), the CPU 31 moves the process to step S95. The CPU 31 determines whether there are other permitted devices (step S95). If there are other permitted devices (YES in step S95), the CPU 31 returns the process to step S92. When there is no other permitted device (NO in step S95), the CPU 31 determines whether or not there is a serial number of the permitted device stored in the RAM 32 or the like by executing step S94 (step S96). If there is a permitted device that stores the serial number (YES in step S96), the CPU 31 notifies the x device 1 of the serial number of the permitted device (step S97). If there is no permitted device storing the serial number (NO in step S96), the CPU 31 notifies that there is no permitted device (step S98), and the CPU 31 ends the process. Note that only the CE terminal in the data center should calculate the distance in step S92. Accordingly, the unauthorized device is of course not a terminal outside the data center. Therefore, a flag may be provided in the permitted device table 35c to manage whether the device is in the data center or outside the data center.

FIG. 24 is a flowchart showing a procedure of failure information transmission processing performed by the x device 1. The process shown in FIG. 24 is a process executed every predetermined time by a timer interrupt. The CPU 11 of the x device 1 transmits the position coordinates of the corresponding device to the position management server 3 (step S45). The CPU 11 determines whether or not a permitted device has been returned from the position management server 3 (step S46). If there is no reply from the permitted device (NO in step S46), the CPU 11 ends the process. When there is a reply from the permitted device (YES in step S46), the CPU 11 reads out the failure information from the device information table 16a (step S43). The CPU 11 transmits the read failure information to the mobile terminal 2 (step S44).
In addition, although what was transmitted to the position management server from the x apparatus 1 in step S45 is the position coordinate, the product name and serial number of the corresponding apparatus may be transmitted. In that case, the location management server 3 receives the product name and serial number in step S91 of FIG. Based on this, the position coordinates of the corresponding device are acquired from the device position table 35a, and then the processing from step S92 is performed.

  In the second embodiment, in addition to the effects achieved by the first embodiment, the following effects are achieved. By polling from the x device 1, even if the location management server 3 does not grasp the association between the x device 1 and the corresponding device, an approach notification of the mobile terminal 2 can be transmitted only to the x device 1 accordingly. It becomes possible.

Embodiment 3
In the first embodiment or the second embodiment, in order to check whether or not all the corresponding devices in the data center are normal, the CE walks around the data center and holds the mobile terminal 2 over the corresponding device to take an image. Need to make sure that the air tag is not displayed. In this case, the efficiency is poor in other large-scale data centers. Therefore, an overall status display function is added in the first embodiment or the second embodiment.

  FIG. 25 is an explanatory diagram showing an example of a record layout of the device position table 35a. Differences from the layout shown in FIG. 6 will be mainly described. The device position table 35a includes a product name column, a serial number. Includes column, position column, and rack number column. Product name column, serial number. The values stored in the column and the position column are as described above. The rack number column stores the number of the rack in which each device is stored. In the present embodiment, it is assumed that if the rack number is known, the position of the corresponding rack in the data center can be known.

  FIG. 26 is a flowchart showing the procedure of the overall status display process. The CPU 21 location management server 3 of the portable terminal 2 is requested for the entire failure status (step S101). The CPU 31 of the location management server 3 receives the request (step S102). The CPU 31 refers to the device information table 35b and confirms whether there is any device in which a failure has occurred (step S103). If there is a failure (YES in step S103), the CPU 31 acquires the serial number and product name where the failure has occurred (step S104). The CPU 31 searches the device position table 35a using the acquired serial number and product name, and acquires the corresponding rack number (step S105). The CPU 31 creates a failure notification using the acquired rack number (step S106). If there is no failure (NO in step S103), the CPU 31 creates a normal notification (step S107). CPU31 transmits the produced notification to portable terminal 2 (Step S108). The CPU 21 of the mobile terminal 2 receives the notification (step S109). The CPU 21 displays the notification on the display unit 27 (step S110). The CPU 21 ends the process.

27 and 28 are explanatory diagrams showing screens of the portable terminal 3 displaying the overall situation. FIG. 27 shows a screen indicating that no failure has occurred. FIG. 28 shows a screen indicating that a failure has occurred. It can be seen that a failure has occurred in the devices attached to the racks A1 and B2. Based on this notification, the CE heads to the racks A1 and B2 and handles the failure. For grasping the failure contents in the racks A1 and B2, the same operation as in the first embodiment or the second embodiment described above may be performed.
Note that the display request for the overall status may be made by an operation such as a pull-down menu.

  In the present embodiment, in addition to the effects exhibited by the first or second embodiment, the following effects are achieved. By providing the overall status display function, the CE can easily confirm whether or not a failure has occurred in another part of the data center after the work is completed.

  FIG. 29 is a functional block diagram of the x device 1. The x device 1 includes a storage unit 10a, a receiving unit 10b, a reading unit 10c, and a transmitting unit 10d. The storage unit 10a stores device information. The receiving unit 10b receives a notification of the approach of the mobile terminal 2. The reading unit 10c reads the device information stored in the storage unit 10a. The transmission unit 10 d transmits the readout device information to the mobile terminal 2.
