Storing the storage system
If the storage system does not receive power for more than six months, the
battery can become discharged and possibly damaged. To avoid this
situation, charge the battery for more than three hours at least once every
six months.
Note: Do not store the equipment in an environment with temperatures of
104ºF (40ºC) or higher because battery life will be shortened.
Using flash module drives
Observe the following guidelines when handling the listed flash module drives
(FMDs). The following types of FMDs are equipped with a battery or capacitor.
Caution: Power up the flash module drives using power from the storage
system for at least 90 minutes every month. Failure to do so can render a
flash module drive unusable and voids replacement under the terms of the
warranty.
