Chapter 3 Maintaining the Server

Replacing a PCIe Riser

The server contains two toolless PCIe risers for horizontal installation of PCIe cards. See
PCIe Card, page 3-43
Power off the server as described in
Step 1
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.
Step 3 Remove the top cover as described in

for the specifications of the PCIe slots on the risers.
Grasp the top of the riser and lift straight up on both ends to disengage its circuit board from the
socket on the motherboard. Set the riser on an antistatic mat.
If the riser has a card installed, remove the card from the riser. See
page 3-43.
If you removed a card from the old PCIe riser, install the card to the new riser (see
Card, page 3-43).
Position the PCIe riser over its socket on the motherboard and over its alignment slots in the chassis
(see Figure 3-24). There are also two alignment pegs on the motherboard for each riser.
The PCIe risers are not interchangeable. If you plug a PCIe riser into the wrong socket, the server
will not boot. Riser 1 must plug into the motherboard socket labeled "RISER1." Riser 2 must
plug into the motherboard socket labeled "RISER2."
Carefully push down on both ends of the PCIe riser to fully engage its circuit board connector with
the socket on the motherboard.
