Replacing a Cache Battery

The cache battery is located inside the cooling unit. The battery assembly is
replaced as an individual part.

Caution
• Try reconditioning the battery before you replace it. See
page 128 or page 183 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 “Browser
Does Not Connect to WebPAM PROe” on page 351.

To replace a cache battery:
1. Verify that the Battery LED is amber or red. See Figure 13.

2. Press the release button and pull the handle downward as shown above.
3. Pull the cooling unit out of the VTrak enclosure. See Figure 14 (E610f/s) or
15 (E310f/s).

3. Loosen the thumbscrews. A retainer keeps the thumbscrews in place.
4. Grasp the top section near the thumbscrews and lift it off the bottom section.
Separate the cooling unit sections to access the battery assemble. See
Figure 16 (E610f/s) or 17 (E310f/s).

5. Remove the two screws holding the battery assembly in place.
6. Detach the connector on the circuit board.
Do not detach any other connectors. See Figure 18 (E610f/s) or 19
(E310f/s).

7. Lift the battery assembly out of the cooling unit.
8. Place a new battery assembly into the cooling unit.
9. Attach the connector on the circuit board.
10. Install the two screws holding the battery assembly in place to the cooling
unit.
11. Place the top section of the cooling unit onto the bottom section and tighten
the thumbscrews.
12. Carefully slide the cooling unit into the enclosure.
