Replacing a PCIe Riser Assembly
The server contains two PCIe risers that are attached to a single riser assembly. Riser 1 provides PCIe
slot 1 and riser 2 provides PCIe slot 2, as shown in
Figure 3-23
. See
Table 3-5
for a description of the
PCIe slots on each riser.

To install or replace a PCIe riser, follow these steps:
Step 1
Remove the PCIe riser assembly that you are replacing:
a.
Power off the server as described in
Shutting Down and Powering Off the Server, 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.
Caution
If you cannot safely view and access the component, remove the server from the rack.
c.
Remove the top cover as described in
Removing and Replacing the Server Top Cover, page 3-8
.
d.
Use two hands to grasp the metal bracket of the riser assembly and lift straight up to disengage its
connectors from the two sockets on the motherboard.
e.
If the riser has any cards installed, remove them from the riser.
Step 2
Install a new PCIe riser assembly:
a.
If you removed any cards from the old riser assembly, install the cards to the new riser assembly (see
Replacing a PCIe Card, page 3-38
).
b.
Position the riser assembly over its two sockets on the motherboard and over the chassis alignment
channels (see
Figure 3-24
):
c.
Carefully push down on both ends of the riser assembly to fully engage its connectors with the two
sockets on the motherboard.
Step 3
Replace the top cover.
Step 4
Replace the server in the rack, replace cables, and then power on the server by pressing the
Power
button.
