Procedure for Upgrading the RAID Firmware

The current RAID BBU (CS-MARS-X10-BB=) is a Lithium ion (Li-ion) battery. Previously, Cisco shipped a Nickel Metal Hydride (NiMH) battery as the RAID BBU. To report the status of the Li-ion RAID BBU, the MARS Appliance must be running RAID firmware version 1.12.220-0560 or more recent. To check the firmware version use the raidstatus CLI command.

---

Step 1 Download the RAID firmware ISO image (cs-mars_raid_1-12-220-0560.iso) from the CS-MARS supplementary files Software Download site: http://tools.cisco.com/support/downloads/pub/Redirect.x?mdfid=279644034

This site requires that you login with your Cisco Connection Online login name and password.

Step 2 Burn the .ISO image to a Compact Disc (CD).

Step 3 Connect a keyboard and an external monitor to the MARS appliance. Establish a direct console connection.

Step 4 Place the RAID Firmware CD into the MARS appliance DVD drive.

Step 5 Reboot the MARS appliance (Enter the reboot CLI command, or power cycle the appliance).

MARS executes a batch file on the CD that launches the RAID firmware update utility which prompts you to upgrade the RAID firmware.

Step 6 Press Enter when the firmware upgrade utility displays "Upgrade RAID Firmware."

MARS then upgrades the firmware and returns you to the DOS shell prompt, "R >".

Step 7 Remove the CD from the MARS DVD drive, and reboot MARS with Ctrl+Alt+Del.

MARS reboots normally.

Step 8 Login to the MARS appliance.

Step 9 Verify the RAID firmware upgrade by entering the raidstatus CLI command at the "pnadmin >" prompt.

The firmware version should be 1.12.220-0560 or more recent.

The RAID array components should have the same status as before the upgrade.

Procedure to Replace the RAID Battery Backup Unit

The RAID BBU replacement procedure can be summarized as follows:

1. Remove the chassis cover.

2. Remove the large air baffle.

3. Remove the RAID BBU.

4. Install the replacement RAID BBU.

5. Replace the large air baffle.

6. Replace the chassis cover.

To replace the Cisco Security MARS RAID BBU complete the following detailed procedure:

---

Note A nonskid surface or a stop behind the MARS Appliance may be needed to prevent the MARS Appliance from sliding on your work surface.

---

Remove the Chassis Cover

---

Step 1 Observe all safety and Electro Static Discharge precautions.

Step 2 Turn off the appliance.

Step 3 Disconnect the AC power cords.

Step 4 Remove the safety screw if it is installed, as shown in callout A of Figure 1.

Step 5 While holding in the blue button at the top of the MARS Appliance (callout B), slide the top cover back until it stops, as shown in callout C of Figure 1.

Step 6 Insert your finger in the notch shown in callout D of Figure 1, then lift the cover upward to remove it.

Step 13 Lower the baffle into the appliance and snap it into the appliance board standoff.

Make sure to route the cables beneath the air baffle as were recorded in Step 7.

Replace the Chassis Cover

Step 14 Place the cover over the MARS Appliance so that the side edges of the cover sit just inside the
MARS Appliance sidewalls.

Step 15 Slide the cover forward until it clicks into place.

Step 16 (Optional) Insert the safety screw at the center of the top cover if required.

Step 17 Reconnect the AC power cords.
