HP Integrity rx7620 Server - User Service Guide, Sixth Edition

4. To check details about the hardware component you plan to power off, use the MP Command

menu PS command.

The PS command enables you to check the status of the cabinet, system backplane, MP core

I/O, PCI power domains (or bricks) in the I/O card cage, and cells.

5. Use the MP Command menu PE command to power off the hardware component.

Using the PE command, you can power the cabinet (including all cells and I/O in the cabinet)

on or off, individual cells along with their associated I/O domain, or PCI power domains

(bricks).

Using the Command menu PE command to manage cabinet power is equivalent to using

the front panel power switch.

6. If you need to disable all power in the entire cabinet, you also must disconnect all power

cords to disable all housekeeping power.

IMPORTANT: Because of power redundancy capabilities, it is important that each power

cord plug into its proper receptacle. Label all power cords to indicate into which receptacle

each cord plugs. Ensure that the cabinet power has been turned off before disconnecting

any power cords.

7. Perform the hardware removal and replacement procedure for the powered off component.

Powering On the System

To power on the system after a repair, follow these steps:

1. If needed, reconnect all the power cords to the appropriate receptacles and power on the

system.

2. To power on the hardware component that was powered off and replaced, use the MP

Command menu PE command.

3. To verify that power is enabled to the newly replaced part, use the PS command. For example:

Enter C from within the PS command to select the cell.

If power is absent from the part, enter the PE command and select T to power on the entire

cabinet.

NOTE: You might need to allow time for some components to complete power on self test

(POST) before a complete status is available.

4. Reboot each nPartition. See Appendix D.

5. Verify system functionality by using the On-line Diagnostic Support Tools Manager (STM)

exerciser.
