Cautions
Try reconditioning the battery before you replace it. See “Recondition-
ing a Battery” on page 120.
The battery assembly is replaced as a unit. Do not attempt to discon-
nect the battery by itself.
Installing the wrong replacement battery can result in an explosion.
Dispose of used batteries according to the instructions that accompany
the battery.
While the battery is removed, your system is vulnerable to data loss if
the power fails while data is being written to the logical drives.
If power service has failed, do not remove the battery if the RAID con-
troller’s dirty cache LED is ashing. See “Rear Panel LEDs” on page
20.
