Replacing a Cache Battery
The cache battery is located inside the Cooling Unit. The battery is replaced as
an individual part.
To replace a cache battery:
1. Verify that the Battery LED is amber or red. See Figure 13.
Figure 13.Fan LED (left: M610i, right: M310i/M210i)
2. Press the release button and pull the handle downward as shown above.
3. Pull the cooling unit out of the VTrak enclosure. See Figures 14 and 15.
Cautions
• Try reconditioning the battery before you replace it. See
page 98 or page 142 for more information.
• 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. See “Unsaved
Data in the Controller Cache” on page 281.
