Description

  The present invention relates to an information processing method, an information processing device, a recording medium, a program, and a control device, and in particular, information suitable for use when operating with power supplied through a plurality of uninterruptible power supply devices. The present invention relates to a processing method, an information processing device, a recording medium, a program, and a control device.

  In recent years, information processing apparatuses represented by personal computers have been widely used, and their importance has been increasing year by year.

  Since power used to drive information processing devices is often supplied directly from commercial AC power, abnormalities such as momentary voltage drop (instant interruption) or sudden power outages of commercial AC power occur. Then, the information processed by the information processing device at that time may be damaged or lost, and a failure may occur in the information processing device such as a failure of the built-in hard disk or the like. .

  In order to avoid the occurrence of such problems, there is a method of providing an uninterruptible power supply (hereinafter also referred to as UPS (Uninterruptible Power Supply)) between the commercial AC power supply and the information processing apparatus (for example, Patent Document 1).

  This UPS supplies power from the commercial AC power source to the information processing device when the commercial AC power source is normal, and replaces the power from the commercial AC power source when an abnormality occurs in the commercial AC power source. Is supplied to the information processing apparatus.

  Therefore, an information processing apparatus to which power is supplied via the UPS by such an operation of the UPS is being executed using the power supplied from the battery in the UPS as the power supply even if an abnormality occurs in the commercial AC power supply. It becomes possible to continue the processing as it is.

  However, the battery built in the UPS is a standby power source, and its power supply capability is limited. In other words, there is a limit to the time during which the battery can output a voltage of a predetermined level or higher (hereinafter referred to as “power supply time”), and the power supply time to the UPS battery is limited. Each needs to be restricted in operation.

  When one information processing device receives power supply from the battery built into the UPS in response to the occurrence of an abnormality in the commercial AC power supply, it stops the processing that has been executed so far within the UPS power supply time, In accordance with a predetermined procedure, a process of transitioning from the operating state to the hibernate state in which no inconvenience occurs even if the power supply is cut off from the operating state (hereinafter, such a series of processes is referred to as a shutdown process) is executed. There is a need to.

  Specifically, for example, when the information processing apparatus is a personal computer or the like, a predetermined OS (Operating System) is started in the information processing apparatus, and application programs that run on the OS are often executed. In this case, as the shutdown process, after the data being processed by each application program is appropriately saved, the application program being executed is terminated and the OS is suspended.

  The other UPS, if the built-in battery is discharged excessively (powering the information processing device), the battery life is shortened or it cannot be used even if it is recharged (redischarged at a voltage level that meets the specifications). It is impossible to do this). Therefore, in order to suppress the occurrence of such a malfunction, the UPS supplies power to the process of stopping the battery discharge as soon as possible after the information processing apparatus completes the shutdown process, that is, the state of the UPS. It is necessary to execute a process of transitioning from a running state to a stopped state in which the supply is stopped (hereinafter, such a process is referred to as a UPS stop process).

  Therefore, as a method for causing UPS to execute UPS stop processing, the present applicant has developed a program for controlling UPS stop processing by UPS from an information processing device (hereinafter referred to as UPS control program) and has already sold it. ing.

  The information processing device installed with this UPS control program monitors the status of one UPS connected to the information processing device, and shuts down when an abnormality occurs in the commercial AC power input to the UPS. While executing the process, the UPS stop process can be executed for the one UPS.

  By the way, in recent years, as another measure for dealing with a power supply abnormality (that is, a measure different from the measure of connecting a UPS between the information processing apparatus and the commercial AC power supply), redundancy has been added to the power supply portion of the information processing apparatus itself. A function to be provided (hereinafter referred to as a redundant power supply function) is also being provided.

  That is, a plurality of power supply units are provided in the power supply part of the information processing apparatus having a redundant power supply function. For example, when an abnormality occurs in any of the plurality of power supply units, the remaining power supply units Necessary power can be supplied to the information processing apparatus.

  Furthermore, if the commercial AC power supply is supplied to each power supply unit of the information processing apparatus having such a redundant power supply function via a different UPS, the reliability of the information processing apparatus against power supply abnormality is further improved. be able to.

  In this way, when supplying commercial AC power to each power supply unit of the information processing apparatus having a redundant power supply function via a different UPS, so that a plurality of UPSs can execute the UPS stop process described above, There are a method of developing the above-described UPS control program so that a plurality of UPSs can be controlled (see Patent Document 2), a method of providing a control device for causing each UPS to execute a UPS stop process, and the like.

  According to the first aspect of the present invention, when commercial AC power is supplied through a plurality of UPSs of an information processing apparatus having a redundant power supply function, each UPS is controlled from the information processing apparatus via a highly versatile network. It is possible to control the control device.

  According to the second aspect of the present invention, it is possible to control the uninterruptible power supply that supplies power to the information processing apparatus having the redundant power supply function so as to suppress the deterioration thereof.

  Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.

  FIG. 1 shows a first configuration example of a system to which the present invention is applied. In the following drawings, a solid line indicates a communication line for communicating data, commands, and the like, and a broken line indicates a power line for supplying power.

  The first configuration example of the system includes a server 1 having a redundant power supply function, and a plurality of UPSs 2-1 to 2-i (i = n + k, where n and k are integers) that supply power to the server 1. Details And UPS control devices 4-1 to 4-i connected to the server 1 via the LAN 3.

  The server 1 has a redundant power supply function as described above. In other words, the server 1 is operated by power supplied via the plurality of UPSs 2-1 to 2-i.

  The UPS 2-1 is supplied with a commercial AC power source 5-1 and has a battery 64 (FIG. 4) built therein. The UPS 2-1 supplies the power of the commercial AC power source 5-1 to the server 1 and the UPS control device 4-1 when the commercial AC power source 5-1 is normal according to the control from the UPS control device 4-1. When an abnormality occurs in the commercial AC power source 5-1, the power of the built-in battery 64 is supplied to the server 1 and the UPS control device 4-1, instead of the power of the commercial AC power source 5-1. Since the same applies to the UPSs 2-2 to 2-i, description thereof will be omitted.

  The LAN 3 is a highly versatile network that communicates data, commands, and the like based on TCP / IP (Transmission Control Protocol / Internet Protocol). Other protocols may be used instead of TCP / IP. Further, instead of the LAN 3, other versatile networks or data buses such as USB (Universal Serial Bus), IEEE (Institute of Electrical and Electronics Engineers) 1394, etc. may be used.

  The UPS control device 4-1 is composed of a computer, for example, and has an IP address in the LAN 3. The UPS control device 4-1 is operated by the power supplied from the UPS 2-1, and the state of the UPS 2-1 (whether it is operating, whether an error has occurred, whether an error has occurred) The UPS 2-1 itself or the commercial AC power supply 5-1 is monitored at any time, and the UPS 2-1 is powered from the commercial AC power supply 5-1 based on the monitoring result. While switching to the battery 64, the UPS 2-1 is caused to execute UPS stop processing.

  Then, the UPS control device 4-1 displays status information indicating the state of the UPS 2-1 (whether it is operating, whether an abnormality has occurred, and if an abnormality has occurred, the UPS 2-1. The server 1 is notified via the LAN 3 of whether it is its own abnormality or the commercial AC power supply 5-1.

  Further, prior to causing the UPS 2-1 to execute the UPS stop process, the UPS control device 4-1 generates a shutdown process instruction that instructs the server 1 to execute the shutdown process, together with the state information described above. The server 1 is notified via the LAN 3.

  The trigger that causes the UPS control device 4-1 to execute UPS stop processing on the UPS 2-1 is based on the arrival of the date and time that can be arbitrarily set by the user in addition to the above-described monitoring result of the UPS 2-1. Some respond quickly to a user's predetermined operation. In any of these cases, a shutdown processing instruction is notified to the server 1 prior to executing the UPS stop processing.

  Since the same applies to the UPS control devices 4-2 to 4-i, the description thereof is omitted. Hereinafter, when it is not necessary to individually distinguish the UPSs 2-1 to 2-i, they are simply referred to as UPS2. The same applies to the UPS control devices 4-1 to 4-i, the commercial AC power supplies 5-1 to 5-i, and the like.

  When attention is paid to a predetermined device (such as the server 1 or the UPS 2), a device that supplies power to the device is referred to as an input power source. For example, when attention is paid to the server 1, a UPS 2 that supplies power to the server 1 serves as an input power source. For example, when attention is paid to the UPS 2, the commercial AC power supply 5 that supplies power to the UPS 2 serves as an input power supply.

  FIG. 2 shows a configuration example of the server 1 according to an embodiment of the present invention.

  The server 1 includes a CPU (Central Processing Unit) 11. An input / output interface 15 is connected to the CPU 11 via the bus 14. A ROM (Read Only Memory) 12 and a RAM (Random Access Memory) 13 are connected to the bus 14.

  The input / output interface 15 includes a keyboard for a user to input operation commands and the like, an input unit 16 including an input device such as a mouse, an output unit 17 including a display for displaying a setting screen, a speaker for outputting sound, and an application program. And a storage unit 18 including a hard disk drive for storing various data, and a communication unit 19 including a LAN adapter and the like for executing communication processing via a network such as the LAN 3 are connected.

  The input / output interface 15 includes a magnetic disk (including a flexible disk), an optical disk (including a CD-ROM (Compact Disc-Read Only Memory), a DVD (Digital Versatile Disc)), and a magneto-optical disk (MD (Mini Disc). Or a drive 20 for reading / writing data from / to a recording medium 21 such as a semiconductor memory.

  Further, a power supply unit 22 that supplies power to each unit of the server 1 is connected to the input / output interface 15. The power supply unit 22 includes i (= n + k) power supply units 24-1 to 24-i and a power supply unit control unit 23 that controls them.

  Power lines from UPS 2-1 to 2-i are connected to the power supply units 24-1 to 24-i, respectively. The power supply units 24-1 to 24-i convert the AC voltage applied from the UPSs 2-1 to 2-i connected by the power lines, respectively, into a predetermined level of DC voltage and output it to each unit of the server 1 To do. However, illustration of the power lines from the power supply units 24-1 to 24-i to the respective units is omitted.

  In addition, when each of the power supply units 24-1 to 24-i is simply connected in parallel, the levels of these output voltages do not strictly match, and as a result, each of the power supply units 24-1 to 24-i Load current (output current) does not match (load current is not balanced). If no countermeasures are taken against this state, the load is concentrated on the power supply units 24-1 to 24-i that output the highest level voltage. Therefore, the power supply unit control unit 23 executes control for equally sharing the loads of the power supply units 24-1 to 24-i (hereinafter referred to as equal load sharing control).

  In addition, the power supply unit control unit 23 constantly monitors the power supply units 24-1 to 24-i, and when an abnormality occurs in at least some of them, the server 1 is driven by an abnormality not occurring. Control for supplying necessary power (hereinafter referred to as redundant power supply control) is executed.

  Note that such a function for executing redundant power control is generally referred to as an n + k redundant power function. In other words, the n + k redundant power supply function refers to power that allows the server 1 to operate normally if at least n of the i (= n + k) power supply units 24-1 to 24-i are operating normally. It is a function that can be supplied.

  Here, n is an integer value determined based on the specifications of the power consumed by the server 1 and the specifications of the power supply units 24-1 to 24-i. On the other hand, k is an arbitrary integer value based on the specification.

  Next, FIG. 3 shows a configuration example of functional blocks related to processing for controlling the UPS control device 4 connected via the LAN 3, which is realized by the CPU 11 of the server 1 executing a predetermined program. . All or some of these functional blocks may be realized by hardware.

  The UPS monitoring unit 31 manages the UPS control devices 4-1 to 4-i connected via the communication unit 19 and the LAN 3 with the IP addresses assigned to the UPS control devices 4-1 to 4-1. 4-i is monitored whenever necessary, and UPS 2 status information (whether the UPS 2 is in operation and whether an abnormality has occurred), which is the monitoring result, is notified to itself. The notified status information is notified to the output unit 17 and the shutdown control unit 32. In addition, when the UPS monitoring unit 31 receives the shutdown processing command notified from the UPS control devices 4-1 to 4-i, the UPS monitoring unit 31 outputs the received shutdown processing command to the shutdown control unit 32.

  When the UPS monitoring unit 31 manages the UPS control devices 4-1 to 4-i, information that can individually identify the UPS control devices 4-1 to 4-i such as a MAC address is used instead of the IP address. May be.

  The shutdown control unit 32 controls the shutdown process of the server 1 itself based on the shutdown process command from the UPS control devices 4-1 to 4-i notified from the UPS monitoring unit 31. In addition, when the power supply from the UPS 2 is restored after the server 1 is put into the hibernation state by the shutdown process, the shutdown control unit 32 restores the server 1 from the hibernation state to the operation state.

  The output unit 17 to which the status information is notified from the UPS monitoring unit 31 presents the monitoring result to the user. Specifically, for example, an icon indicating the state of the UPS 2 is displayed on the screen of the display, or an alarm sound is generated.

  By the way, when the status information of the UPS 2 indicates an abnormality, the content of the status information is roughly divided into information indicating that the UPS 2 itself is abnormal (for example, deterioration of the built-in battery 64, etc.) There are two types of information indicating an abnormality in the commercial AC power supply 5 that is the input power supply of the UPS 2.

  Hereinafter, the latter of the state information indicating abnormality, that is, the information indicating abnormality of the commercial AC power supply 5 is referred to as “input power supply abnormality”.

  Next, FIG. 4 shows a configuration example of the UPS 2 and the UPS control device 4. However, as for the configuration example of the UPS control device 4, only the components related to the control of the UPS 2 are illustrated.

  The UPS 2 supplies power from the commercial AC power supply 5 to the server 1 and the UPS control device 4 when the commercial AC power supply 5 that is an input power supply is normal. And when abnormality generate | occur | produces in the commercial alternating current power supply 5, it replaces with the electric power of the commercial alternating current power supply 5, and the electric power from the built-in battery 64 is supplied to the server 1 and the UPS control apparatus 4. FIG.

  In the UPS 2, the commercial AC power supply 5 that is an input power supply is supplied to the switch 62 via the detection element 61. The detection element 61 is composed of, for example, a detection resistor, detects the state (voltage level, etc.) of the commercial AC power supply 5, and supplies the detection result to the monitoring unit 72 of the UPS monitoring device 4.

  The state of the switch 62 is switched based on control from the control unit 71 of the UPS control device 4. For example, corresponding to the fact that the commercial AC power supply 5 is normal, when the UPS 2 is in an operating state (a state in which power is output), the switch 62 is turned on. On the other hand, when the state of the UPS 2 is changed to a stop state (a state where power output is prohibited), the switch 62 is switched to an off state. When the switch 62 is on, the current from the commercial AC power supply 5 is output to the subsequent stage (converter 63 and terminal 67) of the switch 62, and when the switch 62 is off, the output from the commercial AC power supply 5 to the subsequent stage is cut off.

  Converter 63 converts the AC voltage applied from commercial AC power supply 5 into a DC voltage of a predetermined level and applies it to battery 64. That is, the converter 63 functions as a battery 64 charger. The battery 64 is a standby power supply for supplying power to the server 1 and the UPS control device 4 when an abnormality occurs in the commercial AC power supply 5.

  The state of the switch 65 is switched based on the control of the control unit 71. That is, when the UPS 2 is in an operating state and an abnormality occurs in the commercial AC power supply 5, the switch 65 is switched to the on state by the control unit 71. As a result, the battery 64 is discharged and a predetermined level of DC voltage is applied to the inverter 66. In other cases, the switch 65 is switched to the off state.

  The inverter 66 converts the DC voltage applied by the battery 64 into an AC voltage having the same frequency as that of the commercial AC power supply 5 (50 Hz on the Kanto side, 60 Hz on the Kansai side) and substantially the same level. Voltage power is applied to terminal 68.

  The switch 69 is switched to the terminal 67 or the terminal 68 based on the control from the control unit 71.

  Although the illustrated configuration example of the UPS 2 is a so-called constant commercial power supply method for the sake of simplicity of description, other power supply methods such as a so-called line interactive method, a constant inverter method, and the like may be applied. . Further, components such as a sine wave filter may be added so that a voltage having a waveform approximated to a sine wave can be applied to the server 1 or the like.

  Next, the UPS control device 4 monitors the state of the UPS 2, causes the UPS 2 to execute UPS stop processing based on the monitoring result, and sends the state information indicating the state of the UPS 2 to the server 1 connected via the LAN 3. And includes a control unit 71, a monitoring unit 72, and a communication unit 73.

  The UPS control device 4 is composed of a computer or the like as described above. Therefore, the control unit 71 and the monitoring unit 72 described below are realized by executing predetermined programs. However, of course, both or one of the control unit 71 and the monitoring unit 72 may be implemented as hardware.

  In the UPS control device 4, the control unit 71 causes the monitoring unit 72 to monitor the UPS 2 according to the control from the server 1, and based on the UPS 2 status information supplied from the monitoring unit 72, the UPS 62 switch 62, The state of the switch 65 and the switch 69 is controlled.

  The monitoring unit 72 monitors the state of the UPS 2 itself (for example, deterioration of the battery 64), and status information (operating) indicating the state of the UPS 2 based on the detection result of the state of the commercial AC power supply 5 by the detection element 61. Information indicating whether the UPS 2 itself is abnormal or the commercial AC power supply 5 is abnormal), and control is performed. To the unit 71 and the communication unit 73.

  The communication unit 73 is provided with an IP address that can identify the UPS control device 4 separately from other UPS control devices 4. The server 1 is informed of the UPS 2 status information via the LAN 3 according to TCP / IP. And shutdown processing commands are sent.

  The control of the UPS 2 by the control unit 71 will be specifically described.

  For example, when the UPS 2 is in the operating state and the monitoring unit 72 determines that the commercial AC power supply 5 is normal, the control unit 71 turns on the switch 62 and switches the switch 69 to the terminal 67 side. . Thereby, as described above, the power of the commercial AC power supply 5 is supplied to the server 1 and the UPS control device 4 via the UPS 2. At this time, the state of the switch 65 is arbitrary.

  For example, when the UPS 2 is in an operating state and the monitoring unit 72 determines that an abnormality has occurred in the commercial AC power supply 5, the control unit 71 turns on the switch 65 and sets the switch 69 to the terminal 68 side. Switch to. Thereby, as described above, the power from the battery 64 built in the UPS 2 is supplied to the server 1 and the UPS control device 4 via the switch 65, the inverter 66, and the switch 69. At this time, the state of the switch 62 is arbitrary.

  Thereafter, the UPS stop process is executed. Prior to that, the control unit 71 generates a shutdown process command for the server 1 and outputs it to the communication unit 73 to notify the server 1 via the LAN 3.

  When a predetermined time has elapsed after switching to power supply from the battery 64, the control unit 71 switches the state of the switch 62 and the switch 65 to the off state. Thereby, the power supply from the UPS 2 to the server 1 and the UPS control device 4 is stopped. That is, the UPS stop process of the UPS 2 is executed under the control of the UPS control device 4.

  As described above, the UPS stop process of the UPS 2 is executed under the control of the UPS control device 4 without the server 1 being involved.

  Next, the shutdown process by the server 1 will be described with reference to the flowchart of FIG.

  However, as a premise, the UPSs 2-1 to 2-i are all in an operating state and supply the power of the commercial AC power supply 5 to the server 1, and the OS is activated in the server 1. In addition, it is assumed that a predetermined program that implements the UPS monitoring unit 31, the UPS control unit 32, and the shutdown control unit 32 illustrated in FIG. 3 is executed.

  In step S1, the communication unit 19 of the server 1 starts communication with each UPS control device 4 connected via the LAN 3 according to TCP / IP.

  In step S <b> 2, the UPS monitoring unit 31 causes each UPS control device 4 connected via the communication unit 19 and the LAN 3 to start monitoring the state of the corresponding UPS 2. Correspondingly, status information indicating whether each UPS control device 4 corresponds to the status of the corresponding UPS 2 (whether it is in operation, whether an abnormality has occurred, and if an abnormality has occurred, UPS 2 Information indicating whether it is an abnormality of itself or of the commercial AC power supply 5) starts to be notified to the UPS monitoring unit 31 of the server 1 via the LAN 3 at any time. To get.

  In step S3, the UPS monitoring unit 31 detects one or more UPSs 2 other than “input power supply abnormality” (for example, deterioration of the battery 64, etc.) based on the status information of the UPS 2 notified from each UPS control device 4 as needed. Whether or not has occurred is determined. If it is determined that an abnormality other than “input power supply abnormality” has occurred in one or more UPS 2, the process proceeds to step S4. In step S4, the UPS monitoring unit 31 outputs a predetermined error.

  Specifically, for example, when the abnormality that has occurred is an abnormality of the UPS 2 itself (such as deterioration of the battery 64), the UPS monitoring unit 31 notifies the output unit 17 of information indicating the content of the abnormality. The output unit 17 presents the occurrence of an error to the user, for example, by displaying an icon or popup message indicating the content of the abnormality that has occurred on the image or outputting an alarm sound that indicates the content of the abnormality.

  If it is determined in step S3 that no abnormality other than “input power supply abnormality” has occurred in one or more UPS 2, step S4 is skipped and the process proceeds to step S5.

  In step S <b> 5, the shutdown control unit 32 determines whether or not a shutdown process command has been notified from (i−n + 1) or more UPS control devices 4 via the UPS monitoring unit 31. Here, when it is determined that the shutdown processing command has not been notified from (i−n + 1) or more UPS control devices 4, the number of UPS 2 that supply power to the server 1 based on the commercial AC current 5 is at least n. Since it exists, the server 1 can continue to operate and there is no need to execute the shutdown process. Therefore, the process returns to step S2, and each UPS control unit 4 monitors the corresponding UPS 2 and Notification of status information consisting of monitoring results continues.

  In step S5, when it is determined that the shutdown processing command is notified from (i−n + 1) or more UPS control devices 4, the number of UPS2 servers 1 that can supply power to the server 1 based on the commercial AC current 5 is as follows. The number of servers is less than n, and the server 1 cannot continue operating. Therefore, the process proceeds to step S6. In step S6, the shutdown control unit 32 executes a shutdown process of the server 1 itself.

  In step S <b> 7, the shutdown control unit 32 waits until the power supply that can maintain the server 1 is restored, that is, until the power supply is restored from the n or more UPSs 2. If power supply is restored from n or more UPSs 2, the process proceeds to step S8. In step S <b> 8, the shutdown control unit 32 restores the server 1 from the dormant state to the operating state. Thereafter, the process returns to step S1, and the subsequent processing is repeated.

  This is the end of the description of the shutdown process by the server 1. In the above description, the UPS control device 4 is connected to the UPS 2 in response to the arrival of the date and time arbitrarily set by the user, in addition to the case where the UPS control device 4 executes the UPS stop processing based on the monitoring result of the UPS 2. When executing the stop process or when the UPS control apparatus 4 causes the UPS 2 to execute the UPS stop process in response to a user's predetermined operation, the UPS control apparatus 4 performs the shutdown process prior to the execution of the UPS stop process. This is also applied when notifying the server 1 of an instruction.

  According to the shutdown process described above, the operating state of the server 1 can be maintained unless a shutdown process command is notified from (i−n + 1) or more UPS control devices 4.

  On the other hand, when the shutdown process command is notified from (i−n + 1) or more UPS control devices 4, the shutdown process can be executed promptly, and the power supply from the n or more UPSs 2 can be performed. When it comes back up, it can automatically recover from hibernation to operation.

  As described above, since the UPS 2 stop process is controlled by the UPS control device 4, the resources of the server 1 are not used for this control. Therefore, as compared with the conventional case where the server directly controls the UPS stop process, the load on the server can be reduced.

  Next, FIG. 6 shows a display example of a setting screen for inputting various settings related to the shutdown and UPS stop control processing displayed on the output unit 17 of the server 1. The input unit 16 is used for input from the user to the setting screen 100. This setting screen 100 is a display example when the number of UPS control devices 4 connected to the server 1 via the LAN 3 is two.

  A setting field 101 on the setting screen 100 is for selecting and inputting a model of the UPS control device 4 connected to the server 1. The setting column 102 is used to select and input whether to enable or disable the redundant power supply function of the server 1. The setting fields 103 and 104 are for inputting the IP addresses of the two connected UPS control devices 4. In the setting fields 103 and 104, the search button provided on the side is pressed to search the UPS control device 4 connected to the LAN 3, and the IP address acquired from the searched UPS control device 4 is displayed. It can be entered automatically. The setting column 105 is used to select and input whether or not to display a pop-up message (error output) for notifying the user of the occurrence of an abnormality in the UPS 2.

  The setting fields 106 and 107 are used for selectively inputting the output outlets of the UPS 2 connected to the two UPS control devices 4 respectively. The setting field 108 is for inputting the name of the server 1 in the LAN 3. The setting field 109 is for inputting a delay time until the server 1 itself starts the shutdown process after it is determined that the number of shutdown process commands is larger than a predetermined number.

  The setting column 110 is used to input a time provided for processing corresponding to an external command described below. The setting column 111 is used to input an external command to be executed prior to the shutdown process. The setting column 112 is used for selectively inputting whether or not the OS is automatically restarted after the shutdown process, that is, whether or not the server 1 is automatically restored from the hibernation state to the operation state. . In the displays 113 and 114, each of the two UPS control devices 4 is set in advance until the UPS stop process is started after switching the power supply source of the corresponding UPS 2 from the commercial AC power supply 5 to the battery 64. The waiting time is displayed.

  The user can set the settings related to the server 1 on the setting screen 100 as well as the settings related to the UPS control device 4 and the UPS 2 using the input unit 16 and the output unit 17 of the server 1.
