Description
Battery Health LED. To interpret the
illumination patterns of this LED, see the
following table.
BBWC Status LED. To interpret the
illumination patterns of this LED, see the
following table.
Interpretation
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
fully-charged battery can normally
preserve data for at least 2 days.
The battery lifetime also depends on the
cache module size. For more
information, see the controller
QuickSpecs on the HP website
www.hp.com).
The cache microcontroller is waiting for
the host controller to communicate.
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
unavailable temporarily until charging
is complete. The recharge process takes
between 15 minutes and 2 hours,
depending on the initial capacity of the
battery.
The battery pack is fully charged, and
posted write data is stored in the cache.
The battery pack is fully charged, and
no posted write data exists in the
cache.
An alternating green and amber
flashing pattern indicates that the cache
microcontroller is executing from within
its boot loader and receiving new flash
code from the host controller.
A short circuit exists 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 3 years.
An open circuit exists across the battery
terminals or within the battery pack.
BBWC features are disabled until the
