Working Inside the 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 server in the chassis and power on the blade by pressing the Power button.

Removing a CPU and Heat Sink

You will use these procedures to move a CPU from one server to another, to replace a faulty CPU, or to upgrade from one CPU to

another.

The CPU pick and place tool is required to prevent damage to the connection pins between the motherboard

Note

and the CPU. Do not attempt this procedure without the required tool, which is included with each CPU

option kit.

Procedure

Step 1

Unscrew the four captive screws securing the heat sink to the motherboard.

Loosen one screw by a quarter turn, then move to the next screw. Continue loosening until the heat sink can be lifted off.
