Sun StorageTek 2500 Series Array Release Notes • April 2007
Controller Tray Battery Information
During bootup, the battery light might flash for an extended period. The battery
charger performs a series of battery qualification tests before starting a battery
charge cycle. This series of tests occurs at subsystem power-up. The tests are
automatically reinitialized approximately every 25 hours by a timer.
Each controller tray contains a user-replaceable lithium ion battery pack for cache
backup in case of power loss. The on-board battery is capable of holding a 2-
gigabyte cache for three days (72 hours). The service life of the battery pack is two
years, at the end of which the battery pack must be replaced (it is field-replaceable).
