GS80 Component Removal and Replacement 6-13
Module Removal
1. If the system is not partitioned, shut down the operating system and put the
OCP switch in the Off position. Skip step 2.
2. 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. Note, only hard partitions can be powered off. If
soft partitions are used, both partitions must be shut down and the hard
partition powered off.
3. If the FRU is in a single drawer or top drawer in a dual-drawer system, follow
the procedure in Section 6.1.1 to gain access to the FRU. If the FRU is in the
bottom drawer in a dual-drawer system, follow the procedure in Section 6.1.2
to gain access to the FRU.
4. Identify the target PSM (color code = orange). Note that the orange color code
tag is toward the back of the drawer rather than toward the center unlike all
other modules.
5. Using both hands, one on each module lever, place your index finger on the
catch and thumb on the edge of the lever just below/above the arrow. First
squeeze to release the lever and then pull both levers away from the module
to release it from the QBB backplane.
6. Pull the module from the drawer.
Module Replacement
CAUTION: Damage may result if the levers are closed when the module is not
properly seated. Follow the procedure outlined in Section 6.2.
1. Reverse the steps outlined in the removal procedure.
2. Choose the appropriate method to update the PSM firmware. See Appendix
D. Then update the firmware.
3. Be sure to return the OCP switch to its original position.
Verification
Power on the system. Execute the SRM set sys_serial_num command.
