NOTE: Partition configuration information is available on the HP website at http:// docs.hp.com. For more detail, see the HP Systems Partition Guide: Administration for nPartitions. 3. Access the MP Command menu. From the MP Main menu, enter CM to access the Command menu. 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. You can power on or off the cabinet (including all cells and I/O in the cabinet) using the PE command, as well as 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 which receptacle each cord plugs in to. Ensure that the cabinet power is powered off before disconnecting any power cords. 7. Perform the hardware removal and replacement procedure for the powered off component. Powering On the Server To power on the system after a repair, follow these steps: 1. If needed, reconnect all 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 cell. To power on the entire cabinet if power is absent from the part, enter the PE command and select T. NOTE: You may 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 "Operating System Boot and Shutdown". NOTE: Partition configuration information is available on the HP website at http:// docs.hp.com. For more detail, see the HP Systems Partition Guide: Administration for nPartitions. 5. Verify system functionality by using the Online Diagnostic Support Tools Manager (STM) exerciser.
