Replacing an mLOM Card
The server can use a modular LOM (mLOM) card to provide additional rear-panel connectivity. The
mLOM card socket remains powered when the server is in 12 V standby power mode and it supports the
network communications services interface (NCSI) protocol.
Remove any existing mLOM card (or a blanking panel):
Step 1
a.
b.
Caution If you cannot safely view and access the component, remove the server from the rack.
c.
Step 2 See the location of the mLOM socket in
Cisco modular RAID controller riser to provide clearance.

card horizontally to disengage its connector from the motherboard socket.
Install a new mLOM card:

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
If there is no card in PCIe riser 1 or the RAID card riser, you can access the mLOM socket. Continue
with Step 3.
If there is a card in PCIe riser 1 or the RAID card riser, remove those risers to provide clearance.

Card, page 3-40 for instructions.
Set the mLOM card on the chassis floor so that its connector is aligned with the motherboard socket
and its thumbscrew is aligned with the standoff on the chassis floor.
Push the card's connector into the motherboard socket horizontally.
Tighten the thumbscrew to secure the card to the chassis floor.
