GS160/320 Component Removal and Replacement 4-33
Module Removal
1. If the operating system supports hot-swap I/O, enter the appropriate OS
command to put the target local I/O riser in the hot-swap state. See Section
4.3.1. Skip steps 2 and 3.
2. If the system is not partitioned, shut down the operating system and issue
the SRM power off command. Put the OCP switch in the Off position.
Skip
step 3.
3. If the system is partitioned, from the console connected to the partition with
the target FRU, shut down the operating system and power it off using the
SRM power off command. Put the PSM(s)’ switch in the Service
position. Note, only hard partitions can be powered off. If soft partitions
are used, they must be shut down and the hard partition must be powered
off from the console controlling the partition.
4. Identify the target I/O riser – its yellow Swap OK LED should be lit.
5. Remove the I/O hose(s) from the riser.
6. Loosen by a couple of turns the screw
that allows the swing catch, and
turn it to a vertical position releasing the module’s levers. Using both
hands, one on each lever, pull both levers away from the module releasing it
from the QBB backplane.
7. Remove the module.
Module Replacement
Reverse the steps outlined in the removal procedure. When placing the module
into the system box, make sure the module levers catch properly on the system
box.
Be sure to return the OCP switch to its original position.
Verification
Power up the system and check that the I/O map displays the appropriate PCI
box and its devices. Execute the SRM set sys_serial_num command.
