About this task

Before you remove the battery, consider the following conditions:
  • A battery can be removed while the 2145-SV1 node powered on if one of the following conditions is true:
    • A fix procedure directed you to remove this battery and identified which battery to remove by flashing the battery fault LED.
    • The service assistant GUI or the lsnodebattery command identifies it is safe to remove this battery.
    • The node state is service or candidate; the node status LED is flashing once per second.
    • The battery fault LED is on.
    Important: If at least one of these conditions are not met, the node might change states. The node might leave the system state and enter the service state. This change of state happens because the batteries do not have enough charge for the system state and I/O cache to be saved to disk.
  • Both batteries can be replaced when the 2145-SV1 is powered off.
  • Locate the battery documentation and follow those instructions, in addition to these instructions.

Procedure

  1. Read the safety information before you remove and replace parts, as described in Preparing to remove and replace parts.
