Chapter 4. Installing OptionsThis chapter describes how to install and remove PCI adapters and PCI adapter cassettes.PCI AdaptersNote:: Linux does not support hot–plugging any hot–pluggable PCI adapters ordevices. A system with Linux installed on one or more partitions must beshut down and powered off before replacing any PCI adapter or deviceassigned to a Linux partition. Follow the non–hot–pluggable adapter ordevice procedures when replacing a PCI adapter or device in any partitionwith Linux installed.Most PCI adapters can be removed and replaced, or installed in the system without turningoff the power to the entire system. These adapters are referred to as hot–pluggable PCIadapters. Some adapters are not hot–pluggable and power must be removed from thesystem for adapter removal, replacement, or installation. Though some adapters are nothot–pluggable, they must still be installed in the cassette.Note:: An adapter or an adapter blank filler must be installed into the PCI adaptercassette 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 withis hot–pluggable. See Appendix I. PCI Adapter Placement Reference.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 allapplications where these gaskets are used (for example, riser cards, blank fillers or any ofthe various cassette assemblies).Visually inspect the top and bottom of the gasket strips insuring that they are firmly bondedto the sheet metal. Look for any of the following:• gaskets that are starting to unwrap• gaskets lifting or peeling off of the sheet metal• gaskets protruding from the sheet metal bezel when all cassettes, fillers, or risers areplugged into the system.Inspect both the gasket on the cassette or filler that was removed and the gasket visible inthe PCI slot.If a bad gasket is found on a cassette, then the entire cassette must be replaced with a newcassette and gasket. If a bad gasket is found on a riser card, then the I/O Planar containingthe riser card needs to be replaced.If you are removing a PCI adapter that is:• Not hot–pluggable, go to Removing a Non–Hot–Pluggable PCI Adapter on page 4-7.• Hot–pluggable, go to Hot–Pluggable PCI Adapter on page 4-7.Installing Options4-1
