Chapter 3 Maintaining the Server

Replacing a PCIe Riser

The server contains two toolless PCIe risers for horizontal installation of PCIe cards. See
a description of the PCIe slots on each riser.
Figure 3-20

Power off the server as described in the
page 3-7.
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.
Remove the top cover as described in
page 3-8.
Lift straight up on both ends of the PCIe riser to disengage its circuit board from the socket on the
motherboard.
If the riser has a card installed, remove the card from the riser.
If you removed a card from the old PCIe riser, install the card to the new riser (see
Card, page 3-35).
Position the PCIe riser over its socket on the motherboard and over the chassis alignment features
(see Figure 3-19):
The metal shell of the PCIe riser has alignment slots that engage with pegs on the chassis.
The metal shell has alignment tabs that fit into slots on the chassis rear panel.
Carefully push down on both ends of the PCIe riser to fully engage its circuit board connector with
the socket on the motherboard.
Replace the top cover.
Replace the server in the rack, replace cables, and then power on the server by pressing the Power
button.
