Installing or Replacing Server Components
Replacing a 10-Gb LOM Module
The 10-Gb LOM module is a modular PCIe form-factor card (UCSX-MLOM) that is supported only in
PCIe slot 4 (see
Figure 3-26 ). The module provides two external 10-Gb SFP+ connectors for the rear
panel of the server.
To install or replace a 10-Gb LOM module, follow these steps:
Step 1
Remove the 10-Gb LOM module that you are replacing (see Figure 3-25 ):
a. Power off the server as described in the “Shutting Down and Powering Off the Server” section on
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” section on
page 3-8 .
d.
Open the hinged PCIe card retainer. Pinch the two release latches toward the center of the retainer
while you lift up on the front edge of the retainer to open it (see
Figure 3-24 ).

e.
Lift the module straight up from the motherboard socket.
Note Lift up on both ends of the module evenly to avoid damaging its socket.
Step 2
Install a new 10-Gb LOM module:
a. Align the new module with the empty PCIe slot 4 socket on the motherboard. See Figure 3-25 .
b. Push down evenly on both ends of the module until it is fully seated in the motherboard socket.
c. Ensure that the module rear panel sits flat against the chassis rear panel opening.
