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.

Replacement
Reverse the steps outlined in the removal procedure. Refer to option
documentation to determine if option parameters/switches/jumpers need to be
set.
Verification
Power up the system and check that the device you replaced is seen and
configured in to the system. Refer to option documentation to see if other
verification procedures should be followed.
