Major Subsystem Components
New Feature:
The battery cell packs come with an EEPROM to record the date of
installation; and when the approximate one-year life expectancy is reached
(by checking against the real-time-clock), system administrators will be
notified for replacing the BBU.
In accordance with international transportation regulations, the BBU is only
charged to between 35% and 45% of its total capacity when shipped. After
powering on the subsystem (see
Section 4.1
) the BBU will automatically
start charging its battery cells. It usually requires approximately seven (7)
hours for the battery to be fully charged.
If the battery is not fully charged after twelve (12) hours, a problem might
have occurred with the BBU and you should contact your subsystem vendor
for a replacement. Re-installing the BBU may sometimes correct the fault if
BBU charger has overheated and forced the charging process to halt many
times during the charging process. If the overheating conditions occurred
during the process, charge time must extend the expected twelve hours.
While charging the battery, the LED on the BBU will flash slowly. You can
check battery charge using the RAIDWatch management software or
firmware configuration utility.
WARNING!
The BBU is hot-swappable itself; however, when the controller module is
removed from the subsystem, the BBU is also removed. Do not remove
the controller module unless it becomes absolutely necessary.
