Item 2 Interpretation
(green LED)
Steady glow The cache batteries are being charged.
Fast blink The cache microcontroller is waiting for the
host controller to communicate.
-- One of the following situations is occurring:
• There is a short circuit across the battery
terminals or within the battery pack.
• The host controller is updating the cache
microcontroller firmware.
There is an open circuit across the battery
terminals or within the battery pack.
This display pattern might occur after the
system is powered down. It indicates that the
cache contains data that has not yet been
written to the drives. Restore system power as
soon as possible to prevent data loss. (The
battery lifetime depends on the cache module
size. For further information, refer to the
controller QuickSpecs on the HP website
(http://www.hp.com).)
