Replace Cache Battery

Chapter 6: Maintenance

The cache battery is located in the Cooling Unit 1 (the left one). The battery assembly is replaced as an individual part. No tools are required for this procedure.

Cautions

•Try reconditioning the battery before you replace it. See page 84 or page 137 for more information.

•The battery assembly is replaced as a unit. Do not attempt to disconnect the battery by itself.

•Installing an incorrect replacement battery may 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 a power failure. Temporarily set your cache policy to write- through before starting this procedure. See “Logical Drive Settings” on page 107 (WebPAM PROe) or “Logical Drive Settings and Functions” on page 148 (CLU).

•If power service has failed, do not remove the cooling unit if the Controller’s Dirty Cache LED is flashing. See “Unsaved Data in the Controller Cache” on page 236.

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 VTrak enclosure.
