6: Maintenance and Upgrade Procedures
1”. SGI Altix 450 technology uses an x16 connector (64 wires) or “by 16” in PCI Express card
slots. This technology will support PCIe boards that use connectors up to x16 in size. Table 6-2
shows this concept.
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.
