Remove the CMOS battery

Use this information to remove the CMOS battery.

Before you remove the CMOS battery, complete the following steps:
  1. Read Installation Guidelines and Safety to ensure that you work safely.

  2. If the compute node is installed in a chassis, remove it (see Remove a compute node for instructions).
  3. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with the bezel pointing toward you.
  4. Remove the compute node cover (see Remove the compute node cover for instructions).

To remove the CMOS battery, complete the following steps:

Watch the procedure. A video of the process is available:
