Abstract

PURPOSE:To attain the replacement of a faulty package during the operation of a system and to improve the operating efficiency of the system by using the independent power supplies for the slots and supplying or interrupting the power to only a designated slot with the internal/external control. CONSTITUTION:This processer is provided with a cage 1 to store the slots A-H, a power unit 2 which supplies the power to the slots A-H, a switch box 3 which controls the supply and the interruption of power to each slot, a back panel 6, and the slot power supply terminals 5A-5H. If the slot H, for example, has a fault, an operator operates a switch H housed in the box 3. Then a control signal 13H is released and the supply of power is interrupted to the slot H. The operator operates the switch H again after the replacement of control packages. Then the signal 13H is connected and the power is supplied to the slot H. In other words, a faulty package can be replaced with a nondefect one without stopping the operation of a system.

The cage has a power supply terminal separately for each slot, and a power supply unit that separately supplies or disconnects power to each slot in response to instructions from a control package mounted in each slot.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an information processing apparatus according to a first embodiment of the present invention.

The cage 1 includes a cage 1 that accommodates the slots A to H, a power supply unit 2 that supplies power to the slots A to H, a switch box 3 that corresponds to each slot of A to H, and controls power supply and disconnection. , further comprising a back panel 6 and power supply terminals 5A to 5H for each slot. FIG. 2 shows details of the power supply unit 2, which receives AC power,
Common part 10 that supplies power to each slot power supply unit 11-A to 11-H and each slot power supply unit 11-A to 11-H
shows. Next, power supply to the A slot in the back panel 6 will be explained.

The power supply unit 11-A for the A slot in the power supply unit is connected to the A slot power supply terminal 5A via the A slot power supply line 12A, thereby supplying power to the A slot. Similarly, power is supplied to the H slot.

[0010] Now, the operation when a failure occurs in the H slot will be explained. When a failure occurs, the operator operates the H switch in the switch box 3, the control signal 13H is released, and the power supply to the H slot power supply line 12-H is cut off. Then replace (remove) the control package connected to the H slot.
After that, operate the H switch in switch box 3 again, and control signal 1
Power is supplied to the H slot by connecting 3H. In this way, according to the present invention, defective (faulty package)
This has the effect of making it possible to safely replace only the parts, reducing system outages, increasing operational efficiency, and furthermore making it possible to realize a 24-hour non-stop information processing device.

Next, a second embodiment will be explained based on FIG. 3.

It consists of a cage 100 that accommodates up to eight control packages such as the control package 106, a control section 101 that controls supply and disconnection of power to each slot, and a power supply unit 102 that supplies power to each slot. , power supply terminals 10 for each slot in the back panel 103 via power supplies 107A-H and 108A-H for each slot.
5A to 5H are connected so that power is supplied to them.

Next, the case where the control package 106 becomes a failure will be explained.

[0014] When the control package 106 breaks down or becomes abnormal, a failure notification is sent to the control unit 101 by a control signal 110 via a connector within the control package 106. Control signal 101 received control signal 110
automatically stops (cuts off) the power supply to the H slot power supply line 108H.

Next, after the maintenance personnel safely replaces the failed package, the control signal 110 becomes valid and power is again supplied to the H slot via the control section 101.

Thus, the present invention provides control package 106
When the control unit 101 receives the fault notification from the slot, it controls (cuts off) the power supply line corresponding to each slot, thereby enabling faster maintenance and further improving the operational efficiency of the system.

Next, a third embodiment will be explained based on FIG. 4.

The information processing device 200 includes a cage 201, an external interface control section 202 that receives a control line 210 and controls power supply and disconnection for each slot, a power supply unit 203 that supplies power for each slot, and a power supply unit 203 for each slot. It is composed of detectors 220A to 220H that detect abnormalities.

As in the first and second cases, power is connected to each slot power supply terminal 205A to 205H in the back panel 204 via each slot power supply line 208A to 208H.

Next, a case where an abnormality occurs in the H slot will be explained.

When an abnormality is detected by the detector 220H, it is reported to an external device via the control line 211. Upon receiving this, the external device instructs the external interface control unit 202 to turn off the power via the control line 210. Upon receiving the disconnection instruction, the external interface control unit 202 recognizes the disconnection of the power to the H slot, and disconnects the power supply line 208 for the H slot.
Cut off the power supply to H. Thereafter, as in the other embodiments, after the operator eliminates the fault, the detector 220H is released, and the external interface control unit 202 receives an instruction from the external device to turn on the power to the H slot again via the control line 210.
Power is supplied to the H slot power supply line 208H.

[0022] Since the time from abnormality detection to power cut-off is short in this way, in addition to the effect of preventing the entire system from falling into abnormality, the same effects as in the first and second examples can also be obtained.

Next, a fourth embodiment will be explained based on FIG. 6.

Cage 30 accommodating 8 slots A to H
1. Consists of a power supply unit 303 that individually supplies power to each slot via power supply lines 308H to 308H for each slot, and controls supply and disconnection via control lines 309A to 309H.

When an abnormality (failure) occurs in the H slot, the control line 309H becomes invalid and the power supply unit 303
The power supply unit 303 is constructed so that the output of the power supply unit 303 is cut off.

The same effect as the third embodiment can be obtained.

In the above four examples, eight slots are used in the cage, but there is no restriction as long as the cage has one or more slots.

[0028]

Effects of the Invention As explained above, the present invention separates the power supply to the slots in the cage, and cuts or supplies only the target (designated) slot by controlling from inside and outside. This has the effect of making it possible to replace a faulty package during system operation, making online maintenance possible, increasing the efficiency of system operation, and making it possible to realize a 24-hour non-stop information processing device.
