Replacing a PCIe Riser
The server contains two toolless PCIe risers for horizontal installation of PCIe cards. See Table 3-7 for
a description of the PCIe slots on each riser.
Note PCIe riser 2 (slots 2) is not available in single-CPU configurations.
Figure 3-19 Rear Panel, Showing PCIe Slots
To install or replace a PCIe riser, follow these steps:
Step 1 Remove the PCIe riser that you are replacing (see Figure 3-20):
a. Power off the server as described in the “Shutting Down and Powering Off the Server” section on
page 3-6.
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.
Caution If you cannot safely view and access the component, remove the server from the rack.
