Replacing a Cisco Modular RAID Controller Card
The server has an internal, dedicated PCIe slot on the motherboard for a Cisco modular RAID controller
card (see
Figure 3-19 ).

• Replacing a Modular RAID Controller Transportable Memory Module (TMM), page 3-38
•
Replacing the Supercap Power Module (RAID Backup Battery), page 3-40
Note
You cannot use a hardware RAID controller card and the embedded RAID controller at the same time.
See
RAID Controller Considerations, page C-1 for details about RAID support.
RAID Card Firmware Compatibility
If the PCIe card that you are installing is a RAID controller card, firmware on the RAID controller must
be verified for compatibility with the current Cisco IMC and BIOS versions that are installed on the
server. If not compatible, upgrade or downgrade the RAID controller firmware accordingly using the
Host Upgrade Utility (HUU) for your firmware release to bring it to a compatible level.
See the HUU guide for your Cisco IMC release for instructions on downloading and using the utility to
bring server components to compatible levels:

Replacement Procedure
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 an existing RAID controller card:
a. Disconnect the data cable from the card. Depress the tab on the cable connector and pull.
b.
Disconnect the supercap power module cable from the transportable memory module (TMM), if
present.
c. Lift straight up on the metal bracket that holds the card. The bracket lifts off of two pegs on the
chassis wall.
d.
Loosen the two thumbscrews that hold the card to the metal bracket and then lift the card from the
bracket.
Step 5 Install a new RAID controller card:
