Cache module LEDs

Item 1

(amber

LED)

Item 2

(green LED)

Interpretation

-- Steady glow The cache batteries are being charged.

-- Fast blink The cache microcontroller is waiting for the

host controller to communicate.

Steady glow -- 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.

Fast blink

There is an open circuit across the battery

terminals or within the battery pack.

Slow blink

(once every

16 seconds)

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
