Pci Adapters - IBM pSeries 670 Service Manual

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 SA38-0538.
If you are removing a PCI adapter that is:
v Not hot-pluggable, go to "Removing a Non-Hot-Pluggable PCI Adapter" on page 857.
v Hot-pluggable, go to "Hot-Pluggable PCI Adapter" on page 858.
