Description
2
Green
Auxiliary Power LED. This LED glows steadily when 3.3V
auxiliary voltage is detected. The auxiliary voltage is used
to preserve BBWC data and is available any time that the
system power cords are connected to a power supply.
3
Amber
Battery Health LED. To interpret the illumination patterns of
this LED, see the following table.
4
Green
BBWC Status LED. To interpret the illumination patterns of
this LED, see the following table.

Interpretation
—
One blink every
two 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 fully-charged
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
(

).
—
Double blink, 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.
One blink per
second
One blink per
second
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.

—
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.
Hot-plug fans
CAUTION:
To avoid damage to server components, fan blanks must be installed in fan bays 5
and 6 in a single-processor configuration.
