Replacing a PCIe Card
Note If you are installing a Cisco UCS Virtual Interface Card, there are prerequisite considerations. See
Special Considerations for Cisco UCS Virtual Interface Cards, page 3-36.
Note If you are installing a RAID controller card, see RAID Controller Considerations, page C-1for more
information about supported cards and cabling.
To install or replace a PCIe card, follow these steps:
Step 1 Remove a PCIe card (or a blank filler panel) from the PCIe riser assembly:
a. Shut down and 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.
c. Remove the top cover as described in the “Removing and Replacing the Server Top Cover” section
on page 3-7.
d. Disconnect cables from the PCIe cards that you are replacing.
Tip Label the cables when you disconnect them to aid correct connection to the new card.
e. Grasp both ends of the riser and evenly pull straight up to disengage its circuit board from the socket
on the motherboard. Set the riser on an antistatic surface.
f. Remove the single screw that secures the tab of the card to the riser.
g. Pull evenly on both ends of the card to disengage it from the socket on the riser (or remove a
blanking panel) and then set the card aside.
Step 2 Install a PCIe card:
a. Align the new card with the empty socket on the riser.
b. Push down evenly on both ends of the card until it is fully seated in the socket.
Ensure that the card rear panel tab sits flat against the riser rear panel opening.
c. Replace the screw that secures the tab of the card to the riser.
d. Position the riser over its socket on the motherboard and over its alignment features in the chassis
(see Figure 3-20).
3. Network Communications Services Interface protocol.
4. Slot 1 can operate when the server is in standby power mode.
