Replacing a Cache Battery
The cache battery is located inside the Cooling Unit. The battery is replaced as an individual part.
Cautions
• Try reconditioning the battery before you replace it.
• The battery assembly is replaced as a unit. Do not attempt to
disconnect 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 will be 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 cooling unit if
the Controller’s Dirty Cache LED is flashing.
To replace a cache battery:
1. Press the release button and pull the handle downward as shown above.
2. Pull the cooling unit out of the Astra ES enclosure.
