Replacing an mLOM Card
The server supports a modular LOM (mLOM) card to provide additional rear-panel connectivity. The horizontal
mLOM socket is on the motherboard, under the mRAID riser.
The mLOM socket provides a Gen-3 x16 PCIe lane. The socket remains powered when the server is in 12 V
standby power mode and it supports the network communications services interface (NCSI) protocol.
Step 1
Remove any existing mLOM card (or a blanking panel):
a) Shut down and remove power from the server as described in
Shutting Down and Removing Power From the Server,
.
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.
If you cannot safely view and access the component, remove the server from the rack.
Caution
c) Remove the top cover from the server as described in
Removing the Server Top Cover, on page 28
.
d) Remove the mRAID riser to provide access to the mLOM socket below the riser.
To remove the mRAID riser, use both hands to grasp the external blue handle on the rear and the blue finger-grip on
the front. Lift straight up.
You do not have to disconnect cables from any RAID card or interposer card that is installed in the riser. Carefully
move the riser aside only far enough to provide clearance.
e) Loosen the single captive thumbscrew that secures the mLOM card to the threaded standoff on the chassis floor.
f)
Slide the mLOM card horizontally to free it from the socket, then lift it out of the server.
Step 2
Install a new mLOM card:
a) Set the mLOM card on the chassis floor so that its connector is aligned with the motherboard socket.
b) Push the card horizontally to fully engage the card's edge connector with the socket.
c) Tighten the captive thumbscrew to secure the card to the standoff on the chassis floor.
d) Return the mRAID riser to its socket.
Carefully align the riser's edge connector with the motherboard socket at the same time you align the two channels
on the riser with the two pegs on the inner chassis wall. Press down evenly on both ends of the riser to fully engage
its connector with the motherboard socket.
