11.Pull the right-hand portion of the battery case away from the battery pack, and simultaneously rotate the battery pack into the opening.

12.Connect the battery cable to the battery pack and the cache. Route the battery cable so that the cache and battery pack can be removed together. (If you need to remove the cache to transfer data, the battery pack must remain connected to it so that the data is preserved.)

13.Insert the battery case into the drive slot.

14.Close the server access panel.

15.Install the server in the enclosure.

After installing a battery pack, you might see a POST message during reboot indicating that the array accelerator (cache) is disabled temporarily. This behavior is normal because the new battery pack is likely to have a low charge.

The controller operates properly while the battery pack is recharging, although the performance advantage of the array accelerator is absent. You do not need to take any action because the recharge process begins automatically when the battery pack is installed. When the battery pack has been charged to a predetermined level, the array accelerator is enabled automatically.

Removing a P711m capacitor pack

1.Close all applications, and then power down the server blade. This method flushes all data from the cache module.

2.Observe the FBWC module LEDs (on page 26):

o If the green LED is off and the amber LED is on, the controller is transferring data from DDR memory to flash memory. Wait for data transfer to complete (about 60 seconds), and then proceed with the next step.

o If the amber LED is off, then proceed with the next step.

3.Remove the controller from the server. See the documentation that ships with the server blade.

CAUTION: When connecting or disconnecting the capacitor pack cable, the connectors on the cache module and cable are susceptible to damage. Avoid excessive force and use caution to avoid damage to these connectors.
