Use this information to remove the CMOS battery.

The following notes describe information that you must consider when replacing the battery.

  • IBM has designed this product with your safety in mind. The lithium battery must be handled correctly to avoid possible danger. If you replace the battery, you must adhere to the following instructions.
    Note
    In the U. S., call 1-800-IBM-4333 for information about battery disposal.
  • If you replace the original lithium battery with a heavy-metal battery or a battery with heavy-metal components, be aware of the following environmental consideration. Batteries and accumulators that contain heavy metals must not be disposed of with normal domestic waste. They will be taken back free of charge by the manufacturer, distributor, or representative, to be recycled or disposed of in a proper manner.
  • To order replacement batteries, call 1-800-IBM-SERV within the United States, and 1-800-465-7999 or 1-800-465-6666 within Canada. Outside the U.S. and Canada, call your support center or business partner.

    Statement 2

    CAUTION
    When replacing the lithium battery, use only IBM 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.

To remove the system battery, complete the following steps:

  1. Read the safety information that begins on Safety and Installation guidelines.
  2. Turn off the server and peripheral devices and disconnect the power cords and all external cables, if necessary.
  3. Remove the cover (see Removing the compute node cover).
  4. If necessary, lift the PCI riser-card assembly 2 out of the way (see Removing a PCI riser-cage assembly).
  5. Remove the system battery:
    1. If there is a rubber cover on the battery holder, use your fingers to lift the battery cover from the battery connector.
    2. Use one finger to tilt the battery horizontally out of its socket, pushing it away from the socket.
      Attention
      Neither tilt nor push the battery by using excessive force.
