Replacing a Modular RAID Controller Transportable Memory Module (TMM)
The transportable memory module (TMM) that attaches to the modular RAID controller card can be
installed or replaced after-factory.

Step 1 Power off the server as described in Shutting Down and Powering Off the Server, page 3-9.
Step 2 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.
Step 3 Remove the top cover as described in Removing and Replacing the Server Top Cover, page 3-10.
Step 4 Remove the modular RAID controller card from the server:
a. Lift straight up on the metal bracket that holds the card. The bracket lifts off of two pegs on the
chassis wall (see Figure 3-17).
b. Disconnect the supercap power module cable from the TMM that is attached to the card.
Step 5 Remove the TMM from the modular RAID controller card (see Figure 3-18):
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 6 Install a TMM to the modular RAID controller card (see Figure 3-18):
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 7 Install the modular RAID controller card back into the server:
Note If this is a first-time installation of your TMM, you must also install a supercap power module (SCPM).
The SCPM cable attaches to a connector on the TMM. See Replacing the Supercap Power Module
(RAID Backup Battery), page 3-34.
a. Connect the cable from the supercap power module (RAID battery) to the connector on the TMM
(see Figure 3-18).
b. Align the two slots on the back of the RAID card bracket with the two pegs on the chassis wall.
