Servicing a Blade Server

Installing a CMOS Battery

All Cisco UCS blade servers use a CR2032 battery to preserve BIOS settings while the server is not installed

in a powered-on chassis. Cisco supports the industry standard CR2032 battery that is available at most

electronics stores.

Warning

There is danger of explosion if the battery is replaced incorrectly. Replace the battery only with the same or

equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's

instructions.

To install or replace the battery, follow these steps:

Procedure

Step 1

Remove the existing battery:

a) Power off the blade, remove it from the chassis, and remove the top cover.

b) Push the battery socket retaining clip away from the battery.

c) Lift the battery from the socket. Use needle-nose pliers to grasp the battery if there is not enough clearance

for your fingers.

Step 2

Install the replacement battery:

a) Push the battery socket retaining clip away from where the battery fits in the housing.

b) Insert the new battery into the socket with the battery's positive (+) marking facing away from the retaining

clip. Ensure that the retaining clip can click over the top of the battery to secure it in the housing.

c) Replace the top cover.

d) Replace the blade server in the chassis.
