Appendix E. Removing and Replacing PCI Adapters

This appendix contains removal and replacement procedures for PCI adapters.
Note: Linux does not support hot-plugging any hot-pluggable PCI adapters or devices. A system with
Linux installed on one or more partitions must be shut down and powered off before replacing any
PCI adapter or device assigned to a Linux partition. Follow the non-hot-pluggable adapter or device
procedures when replacing a PCI adapter or device in any partition with Linux installed.
Most PCI adapters can be removed and replaced, or installed in the system without turning off the power
to the entire system. These adapters are referred to as hot-pluggable PCI adapters. Some adapters are
not hot-pluggable and power must be removed from the system for adapter removal, replacement, or
installation. Though some adapters are not hot-pluggable, they must still be installed in the cassette.
Note: An adapter or an adapter blank filler must be installed into the PCI adapter cassette assembly
before it is reinstalled in a system unit or an I/O drawer.
Before you remove or replace an adapter, determine if the PCI adapter you are working with is
hot-pluggable. See the PCI Adapter Placement Reference, order number SA23-2504.
When assembling, inserting or removing a blindswap cassette, verify that the foam "T-shaped" EMC
gasket strip is firmly attached to the sheet metal bezel. This includes all applications where these gaskets
are used (for example, riser cards, blank fillers or any of the various cassette assemblies).
Visually inspect the top and bottom of the gasket strips insuring that they are firmly bonded to the sheet
metal. Look for any of the following:
v gaskets that are starting to unwrap
v gaskets lifting or peeling off of the sheet metal
v gaskets protruding from the sheet metal bezel when all cassettes, fillers, or risers are plugged into the
system.
Inspect both the gasket on the cassette or filler that was removed and the gasket visible in the PCI slot.
If a bad gasket is found on a cassette, then the entire cassette must be replaced with a new cassette and
gasket. If a bad gasket is found on a riser card, then the I/O Planar containing the riser card needs to be
replaced.
If you are removing a PCI adapter that is:
v Not hot-pluggable, go to "Removing a Non-Hot-Pluggable PCI Adapter" on page 193.
v Hot-pluggable, go to "Hot-Pluggable PCI Adapter" on page 194.
