Replacing the battery

Use this information to install the battery in the CMM.

Before you install the battery, complete the following steps:

1. Read Safety and Installation guidelines.
2. If the CMM is installed in a Flex System chassis, remove it (see Removing a Chassis Management Module 2 for instructions).

The following notes describe information that you must consider when you replace the battery in the Chassis Management Module 2:

• You must replace the battery with a lithium battery of the same type from the same manufacturer.
• To order replacement batteries, call 1-800-426-7378 within the United States, and 1-800-465-7999 or 1-800-465-6666 within Canada. Outside the U.S. and Canada, call your Lenovo sales representative or Lenovo reseller.
• After you replace the battery, you must reconfigure the Chassis Management Module 2 and reset the date and time.
• To avoid possible danger, read and follow the following safety statement.

Statement 2

CAUTION

When replacing the lithium battery, use only Part Number 33F8354 or an equivalent type battery recommended by the manufacturer. If your system has a module containing a lithium battery, replace it only with the same module type made by the same manufacturer. The battery contains lithium and can explode if not properly used, handled, or disposed of.

Do not:

• Throw or immerse into water
• Heat to more than 100° C (212° F)
• Repair or disassemble

Dispose of the battery as required by local ordinances or regulations.

Attention

Touching the battery on a metal surface, such as the side of the Chassis Management Module 2, when you replace the battery can cause it to fail.

To install the battery, complete the following steps:

1. Make sure that the CMM is on a flat, static-protective surface, with the release handle side up and the bezel pointing toward you.
2. If the CMM cover is installed, remove it:
   1. Locate and remove the screws on each side of the CMM cover, toward the rear of the CMM.

      

   2. Open and remove the CMM cover by lifting the rear edge.

      

3. Locate the battery. The battery is typically toward the side of the CMM system board.

   

4. If a battery is already installed, remove it:
   1. Using your fingernail, press the battery retaining clip. The battery should pop free.

      

   2. Lift the battery from the socket.
5. Follow any special handling and installation instructions that come with the battery.
6. Tilt the battery so that you can insert it into the socket.

   

7. As you slide the battery into place, press the battery down into the socket.
8. Install the CMM cover:
   1. Orient the cover so that the front edge of the cover slides into the slot on the CMM; then, lower the rear edge of the cover to close it.
      Note

      Before you close the cover, make sure that all components are installed and seated correctly and that you have not left loose tools or parts inside the CMM.

      

   2. Install the screws on each side of the CMM cover, toward the rear of the CMM.

      

After you install the battery, complete the following steps:

1. Install the Chassis Management Module 2 into the chassis (see Replacing a Chassis Management Module 2 and Cabling the CMM for instructions).
2. Configure the Chassis Management Module 2 (see Configuring the CMM for instructions).
