Removal
1. If the operating system in control of the PCI containing the target FRU
supports hot-swap I/O and taking the I/O resources away from it will allow
it to continue to operate, follow operating system procedures to put the local
I/O riser into the hot-swap state. See Section 4.3.1 and skip to step 4.
2. If the system is not partitioned, shut down the operating system and issue
the SCM power off command. Put the OCP switch in the Off position.
Skip to step 4.
3. If the system is partitioned, from the console connected to the partition to
which the PCI box containing the target FRU is attached, shut down the
operating system and power it off using the SRM power off command.
Put
the OCP switch in the Secure position. Pull the plugs on the target PCI
power supplies.
4. Follow the procedure described in Section 5.1 to gain access to the PCI card
cage section of the box. Be sure to unplug both power supplies at the front
of the PCI box.
5. Disconnect the hose from the I/O riser you are replacing at the bulkhead.
6. Remove the screw holding the module to the frame at the bulkhead of the
card cage.
7. Lift the securing levers at both ends of the module to release it from its
connector on the backplane.
8. Remove the module.
Replacement
Reverse the steps outlined in the removal procedure.
Verification
Power up the system and check that the system sees the I/O devices attached
through the remote riser you replaced. Execute the SRM set sys_serial_num
command.
