Battery-Backed Write Cache Enabler
When the BBWCE is connected to the controller and the server is powered on, the
green LED indicates the status of the battery charge. When the battery is connected to
the controller and the server is powered down, the amber LED indicates the status of
the data retention. Use Figure E-8 and Table E-12 to identify the location and status
of each of the LEDs.
