The procedures are the same for removing of the replacement for the appropriate
FRU. Some steps for deleting a FRU are the same as for replacing a FRU. For more
details about the deletion procedure, refer to the appropriate chapter on FRU
replacement.
Caution – For deletion, a filler panel (TABLE 25-1) must be installed in the empty
slot. Without filler panels, the system might overheat.

■ Press and hold down (for less than four seconds) the POWER switch on the

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.
