PCIe Configuration Guide
For the best performance, we recommend that you populate the PCIe slots in the order shown in
Table 3-5 for each type of add-on card. For each card type, populate the primary slot first, followed by
the secondary slot, then any alternate slots. See Figure 3-26 for the slot locations.
Replacing a PCIe Card in a Riser Slot
Note If you are installing a Cisco UCS Virtual Interface Card, there are prerequisite considerations. See
Special Considerations for Cisco UCS Virtual Interface Cards, page 3-50 .
To install or replace a PCIe card in standard-profile slots 1 or 7 on the PCIe risers, follow these steps:
Step 1
Remove a PCIe card (or a blank filler panel) from the PCIe riser assembly:
a.
Shut down and power off the server as described in the “Shutting Down and Powering Off the
Server” section on page 3-7 .
b. Slide the server out the front of the rack far enough so that you can remove the top cover. You might
have to detach cables from the rear panel to provide clearance.
