4. Add the FRUs.
Some steps for adding a FRU are the same as for replacing a FRU. For more
details about the addition procedure, refer to the appropriate chapter on FRU
replacement.
Note – In addition of an IOU, mount the CMU and IOU in the proper location.
Otherwise, the added IOU may not operate after power-on.
5. Switch on all main line switches for the AC section (ACS) in the power supply
system.
6. Confirm that the XSCF STANDBY LED (green) on the operator panel remains
lit. If it is blinking, wait until it remains lit.
7. Start (turn on power to) all domains together using one of these steps:
■ Press and hold down (for less than four seconds) the POWER switch on the
operator panel.
■ Execute the poweron -a command from XSCF.
8. Confirm that the addition components are normal by using the showhardconf
or showstatus command of XSCF.
If "*" is not displayed for the addition FRU, it is operating normally.
Note – The showhardconf command cannot check the PCI card, Hard Disk Drive,
and tape drive unit. To check the Hard Disk Drive and tape drive unit, use the
probe-scsi-all command from the ok prompt. To check the PCI card, use the
show-devs command from the ok prompt.
9. When CMUs or IOUs are added, perform the SB settings and domain settings
for each CMU and IOU.
Ask a system administrator or a domain administrator for assistance.
10. Set the mode switch on the operator panel to Locked.
