Step 1
Prepare the server for component installation:
a.
Power off the server as described in
Shutting Down and Powering Off the Server, page 3-8
.
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, page 3-9
Step 2
Remove the RAID controller riser from the server (see
):
a.
Disconnect the SAS cable from the existing RAID controller card.
b.
Lift the riser straight up to disengage the riser from the motherboard socket. The riser bracket must
also lift off of two pegs that hold it to the inner chassis wall.
c.
Set the riser upside down.
Step 3
Remove the card from the riser:
a.
Loosen the single thumbscrew that secures the card to the metal riser bracket (see
).
b.
Pull the card straight out from its socket on the riser and the guide channel on the riser bracket.
c.
Set the card on an antistatic surface.
Step 4
Remove a TMM from the modular RAID controller card (see
a.
The plastic bracket on the card has a securing plastic clip at each end of the TMM. Gently spread
each clip away from the TMM.
b.
Pull straight up on the TMM to lift it off the two plastic guide pegs and the socket on the card.
Step 5
Install a TMM to the modular RAID controller card (see
a.
Align the TMM over the bracket on the card. Align the connector on the underside of the TMM with
the socket on the card. Align the two guide holes on the TMM over the two guide pegs on the card.
Caution
In the next step, keep the TMM level and parallel with the surface of the card to avoid damaging the
connector or socket.
b.
Gently lower the TMM so that the guide holes on the TMM go over the guide pegs on the card.
c.
Press down on the TMM until the plastic clips on the bracket close over each end of the TMM.
d.
Press down on the TMM to fully seat its connector with the socket on the card.
Step 6
Install the modular RAID controller card back into the riser:
