4.7 Installing a PCI Riser Card
The NSN2U server does not ship with a PCI riser card, just the sheet metal bracket
where the riser card and PCI add-in cards are housed. There are three different PCI
riser card options that all use the same header connection on the T5520 UR server
board:
•
2U PCIe “butterfly” riser (three full-height/full-length PCIe x8 slots and two low-
profile PCIe x4 slots
• 2U PCIe/PCI-X “butterfly” riser (two PCI-X 133 slots, one full-height/full-length
PCIe x8 slot, and two low-profile PCIe x4 slots)
• 2U PCIe passive riser (three full-height/full-length PCIe x8 slots)
In this section, the riser card example is a full-height, full-length riser, as shown
in Figure 36.

CAUTION: When handling the riser card, observe normal safety and ESD precautions. (See
Appendix A: Safety Information” for more information.
To install the riser card in the sheet metal bracket:
1. Remove the back chassis cover. For instructions, see “Removing the Back Cover” in
Section 3.2.
2. Remove the riser card assembly from the chassis and place it upside-down. For
instructions, see “Removing the Riser Card Assembly“ in Section 3.2.
3. Holding the riser card upside-down with the edge connector on top, line the keyhole
features up with the standoffs on the bracket. (Figure 36, “A”)
