Replacing the system battery

Before you install the system battery, complete the following steps:
  1. Read Safety and Installation guidelines.
  2. If the compute node is installed in a NeXtScale n1200 Enclosure, remove it (see Removing a compute node from a chassis for instructions).
  3. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with the bezel pointing toward you.

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

  • When replacing the system battery, you must replace it 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 marketing representative or authorized reseller.
  • After you replace the system-board battery, you must reconfigure the server and reset the system date and time.
  • To avoid possible danger, read and follow the following safety statement.
Statement 2

CAUTION

When replacing the lithium battery, use only Lenovo 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 install the replacement system battery, complete the following steps:

  1. Follow any special handling and installation instructions that come with the replacement battery.
  2. Remove the cover (see Removing the compute node cover).
  3. If necessary, lift the PCI riser-card assembly 2 out of the way (see Removing a PCI riser-cage assembly).
  4. Insert the new battery:
    1. Orient the battery so that the positive side faces up.
    2. Tilt the battery so that you can insert it into the socket on the side opposite the battery clip.

    3. Press the battery down into the socket until it clicks into place. Make sure that the battery clip holds the battery securely.
  5. Reinstall the PCI riser-card assembly 2 (see Replacing a PCI riser-cage assembly), if necessary.
  6. Install the cover (see Installing the compute node cover).
  7. Slide the server into the rack.
  8. Reconnect the external cables; then, reconnect the power cords and turn on the peripheral devices and the server.
  9. Start the Setup utility and reset the configuration.
    • Set the system date and time.
    • Set the power-on password.
    • Reconfigure the server.
    See Using the Setup utility for details.
