Removing the battery: 2145-DH8

Following all safety notices, you can replace either battery for the SAN Volume Controller 2145-DH8 node.

Before you begin

CAUTION:
The battery is a lithium ion battery. To avoid possible explosions, do not burn. Exchange only with the approved part. Recycle or discard the battery as instructed by local regulations. (C007a)

Use the reference numbers in parentheses at the end of each notice (for example, D005) to find the matching translated notice in IBM System Storage SAN Volume Controller Safety Notices.

About this task

Before you remove the battery, consider the following conditions:
  • A battery can be removed with the 2145-DH8 node powered on if one of the following 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 status 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, then the node might change states, leaving the system state and entering 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-DH8 is powered off.
  • Locate the battery documentation and follow those instructions, in addition to these instructions.

  2. Pull the battery catch and swing down the front cover of the battery.
  3. Gently pull the battery assembly out of the battery slot, as shown in Figure 1.
