Replacing a PCIe Riser
Note
The older PCIe risers UCSC-PCIE-RL-C240= and UCSC-PCIE-RR-C240= are compatible only with the
older version V01 chassis, and have been obsoleted. These parts have been replaced by a new single item
(UCSC-GPUKIT1-C240=), which contains left and right risers along with additional hardware to
facilitate installation of NVIDIA GPU cards. Order the new UCSC-GPUKIT1-C240= if riser
replacement is required on any version of the C240 chassis, or if a version V01 chassis must be upgraded
to support an NVIDIA GPU card. See also
How to Determine Your Server Version, page 3-50
The server contains two toolless PCIe risers for horizontal installation of PCIe cards. PCIe riser 2 also
includes two internal sockets for SD cards. See
Replacing a PCIe Card, page 3-40
for specifications of
the PCIe slots on the risers.

To install or replace a PCIe riser, follow these steps:
Step 1
Remove the PCIe riser that you are replacing (see
a.
Power off the server as described in the
“Shutting Down and Powering Off the Server” section on
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” section on
d.
Disconnect external cables from any PCIe cards that are installed in the PCIe riser.
e.
Use the finger holes to lift straight up on both ends of the riser to disengage its circuit board from
the socket on the motherboard. Set the riser on an antistatic mat.
f.
If the riser has a card installed, remove the card from the riser.
To remove a card, push down on the retaining clip on the hinged card retainer and then swing open
the retainer to free the rear-panel tab of the card (see
Replacing a PCIe Card, page 3-40
).
