Replacing a backup battery pack

Use the following procedure if the DS4000 Storage Manager client instructs you to
replace the battery because the current battery has failed. You can also use the
DS4000 Storage Manager client to check the status of the battery. Because
write-caching is disabled when either one of the backup battery packs fail, IBM
recommends that you replace the failed battery pack as soon as possible to
minimize any impact due to the disabling of the write-caching function.
Replace only the battery pack that is indicated as failed by the LEDs. You do not
need to replace both battery packs when the Battery LEDs indicate that only one
battery pack has failed.

profile.
2. Locate the storage subsystem that contains the interconnect-battery unit with
the failed battery by checking the Overall DS4800 Configuration Needs
Attention LED on the front bezel of the storage subsystem. (Figure 97 on page
161 shows the location of the Overall DS4800 Configuration Needs Attention
LED on the front bezel.)
