Interpretation
-- One blink

seconds
The system is powered down, and the cache contains data that
has not yet been written to the drives. Restore system power as
soon as possible to prevent data loss.
Data preservation time is extended any time that 3.3 V
auxiliary power is available, as indicated by LED 2. In the
absence of auxiliary power, battery power alone preserves the
data. A fullycharged battery can normally preserve data for at
least two days.
The battery lifetime also depends on the cache module size. For
further information, refer to the controller QuickSpecs on the
HP website (http://www.hp.com).
-- Blink twice,
then pause
The cache microcontroller is waiting for the host controller to
communicate.
-- One blink
per second
The battery pack is below the minimum charge level and is
being charged. Features that require a battery (such as write
cache, capacity expansion, stripe size migration, and RAID
migration) are temporarily unavailable until charging is
complete. The recharge process takes between 15 minutes and
two hours, depending on the initial capacity of the battery.
-- Steady glow The battery pack is fully charged, and posted write data is
stored in the cache.
-- Off The battery pack is fully charged, and there is no posted write
data in the cache.

An alternating green and amber blink pattern indicates that
the cache microcontroller is executing from within its boot
loader and receiving new flash code from the host controller.
Steady glow -- There is a short circuit across the battery terminals or within
the battery pack. BBWC features are disabled until the battery
pack is replaced. The life expectancy of a battery pack is
typically more than three years.
One blink

-- There is an open circuit across the battery terminals or within
the battery pack. BBWC features are disabled until the battery
pack is replaced. The life expectancy of a battery pack is
typically more than three years.
