Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an uninterruptible power supply (UPS) power control method, and more particularly to a UPS management and power-on method from a terminal on a network.

[0002]

2. Description of the Related Art Conventionally, when a basic processing apparatus is powered on from a terminal on a network, a packet transmitted by the terminal is transmitted to an uninterruptible power supply (Uninterrupt power supply) connected to the basic processing apparatus.
ablePower Supply (also called "UPS") LAN
(Local Area Network) card or an IP (Internet) in which the transmission source address of the captured packet is registered in advance by a communication control unit which is always energized.
Protocol) address or physical address,
There is known a method of instructing the UPS to output power and turning on the power of the basic processing device. For example, JP-A-7-
In Japanese Patent No. 30565, a communication control device in a server is always energized as a remote power supply control device of a communication network which enables remote control of a server power supply from each client at any time using a normal frame. When a frame is received from a client, it is determined whether the protocol type is RARP, which is a protocol for translating a physical address unique to the client into a logical address. If the protocol type is RARP, the source of the frame is registered. There has been proposed a configuration in which it is determined whether or not a communication address exists in a certain physical address, and if there is a match, the communication control device instructs the power supply control device in the server to turn on the power.

[0003] For example, in Japanese Patent Application Laid-Open No. Hei 5-100970, a self-address of the basic processing device (server) is copied and stored in a power supply control device connected to the basic processing device, and transmitted from a terminal. The received packet is monitored, and when the destination address in the packet matches the stored self-address of the basic processing device, it is determined that the basic processing device has been accessed, and the basic processing device is accessed. A multi-computer system in a local area network has been proposed, in which a power-on signal is sent to a basic processing device.

[0004]

However, according to the above-mentioned conventional technology and the technology described in Japanese Patent Application Laid-Open No. Hei 7-30565, a terminal connected to a network transmits a packet to the network for a purpose other than access to the basic processing device. Is transmitted, the UPS LAN card or the always-on communication controller detects the terminal address and turns on the power of the basic processing device.

[0005] Further, since the address of the terminal must be registered in advance, every time a new terminal to be connected is added in the system configuration, the table in which the address is registered is changed and added. Update work must be performed.

In addition, the number of terminals that can be registered is limited by the storage capacity of a table for registering terminal addresses, and the system cannot be adapted to a system having a certain size or more. There's a problem.

Next, according to the technique described in Japanese Patent Laid-Open No. Hei 5-100970, any terminal connected to the network can turn on the power of the basic processing device. If it has been done, as long as you know only the address of the basic processing unit,
Anyone can start up the basic processing device, which poses a security problem. In addition, even when the address of the basic processing device is erroneously transmitted on the network, the basic processing device similarly starts up.

Further, in any of the above-mentioned conventional techniques, since it takes time from the terminal side accessing the basic processing device to the start of the basic processing device, the first access times out (basic access). Since the processing device has not been started, the access is not accepted by the basic processing device and, for example, a timeout occurs on a protocol), and a retry is required after a delay. In addition, during that time, no message is displayed on the terminal side, and there is no way to know whether the basic processing device is in the process of starting up. Therefore, there is a problem in terms of convenience.

Accordingly, the present invention has been made in view of the above problems, and has as its object to provide an uninterruptible power supply (UPS) connected to a basic processing device on a network.
By using general browsing software for power supply control, even if the basic processing device is not running, the status of the basic processing device and the UPS can be confirmed from a terminal on the network, and the terminal address is registered in advance. Without
By controlling the power of the UPS from a terminal on the network, the power of the basic processing device can be easily turned on.
An object of the present invention is to provide a power control method that ensures operational security.

[0010]

In order to achieve the above object, a power supply control method for an uninterruptible power supply (UPS) according to the present invention uses a basic processing unit and the state of the UPS by browsing software on a terminal side on a network. The power of the basic processing device is turned on by controlling the power of the UPS from the displayed and viewing software.

More specifically, a power supply control method for an uninterruptible power supply according to the present invention includes a basic processing device connected to a network, a terminal, and an uninterruptible power supply. Software is installed, the uninterruptible power supply is connected to the basic processing device, manages the state of the basic processing device and its own device, monitors packets sent on the network, and executes the basic processing. In a case where the terminal accesses the basic processing device when the device is not started, information including the status of the basic processing device and the uninterruptible power supply is read by the browsing software of the terminal on the network. To notify the state of the basic processing device and the uninterruptible power supply, the start-up request of the basic processing device from the browsing software of the terminal In this case, the uninterruptible power supply receives the password input from the terminal, checks the password against a pre-registered password, and if the password matches, supplies power to the basic processing device. So that power is turned on to the basic processing device.

FIG. 2 is a flowchart for explaining a processing flow during normal operation in one embodiment of the present invention. FIG. 3 is a flowchart for explaining a processing flow at the time of normal operation in one embodiment of the present invention. The operation of this embodiment will be described below with reference to FIGS.

As an initial setting, the UPS 200 sets a password necessary for controlling the power of the UPS 200 from the basic processing device 100 through the server interface unit 240 and the self-address of the basic processing device 100 and the viewing software (FIG. 2). Step 21 and Step 2
2) The data is stored in the address storage area 261 and the password storage area 263 in the nonvolatile storage unit 260, respectively.

The status storage area 262 in the non-volatile storage section 260 of the UPS 200 stores the states of the basic processing device 100 and the UPS 200 (step 23,
Step 24), the HTML creation unit 250 creates an HTML sentence by embedding the parameters in the status storage area 262 (step 25), and stores it in the HTML storage unit 264 (step 26).

During normal operation, the status storage area 262 in the non-volatile storage section 260 of the UPS 200 is stored every time the state of the basic processing device 100 and the UPS 200 changes (FIG. 3).
Steps 31 and 32), and receives and stores the respective statuses from the server interface unit 240 and the UPS control unit 270 (Step 33).

The HTML creation unit 250 notifies the central processing unit 2 that the status of the status storage area 262 has changed.
When the status is detected through 30, the status of the status storage area 262 is read, and the status parameter of the HTML statement in the prepared HTML statement storage area 264 is updated (step 34).

Here, it is assumed that the terminal 300 has accessed the basic processing apparatus 100 that has been shut down and is in the power-off state using the viewing software (step 35).

In this case, the UPS 200 monitors the packet from the terminal 300, and checks the self-address of the basic processing device 100 in which the partner address in the packet is registered in the address storage area 261 in the nonvolatile storage unit 260 in advance. If they match, the HTML sentence stored in the HTML sentence storage area 264 is displayed on a terminal on the network (step 36). This allows the terminal 300 to be notified of the states of the basic processing device 100 and the UPS 200.
