Adding or Replacing PCI/PCI-X Cards

Warning: Before installing, operating, or servicing any part of this product, read the “Safety Information” on page 165.

This section provides instructions for adding or replacing a PCI/PCI-X card in the I/O blade or PCI expansion blades installed in your system’s Individual Rack Units (IRUs). To maximize the operating efficiency of your cards, be sure to read all the introductory matter before beginning the installation.

There are different types of blades used in the IRU that hold PCI/PCI-X boards. Note the following guidelines:

•The IA/IA2 blade (base I/O blade) containing the system disk and DVD drive will only accommodate half-height PCI/PCI-X cards.

•The three-slot double-wide PCI blade supports only PCI/PCI-X cards that mount and install with an SGI sliding card carrier.
