EonStor S12E-R1132-4/G1133-2 Installation and Hardware Reference Manual
Figure 1-17: Optional BBU for S12E-G1133-2
An optional, separately purchased Li-Ion battery backup unit (BBU)
module (see
Figure 1-16
and
Figure 1-17
) can sustain cache
memory for days during the event of power outage. The battery
module comes with an EEPROM that marks the installation date, and
system administrators will be notified when the one-year lift
expectancy is reached. Please refer to
Section 2.8
for installation
instructions.
In accordance with international transportation regulations, the BBU
module is only charged to between 35% and 45% of its total capacity
when shipped. Therefore, when powering on the subsystem for the
first time (see
Section 4.4
) the BBU will begin to charge its batteries
to their full capacity. It normally requires approximately twelve (12)
hours for the battery to be fully charged. If the battery is not fully
charged after twelve (12) hours, there may be a problem with the
BBU module. You may re-install the battery; and if the battery still
shows problems with charging, contact your subsystem vendor for a
replacement. While the battery is being charged, the LED on the BBU
will start flashing. (See
Section 3.2.4
for details on the LED
indicators.)
You can check battery’s charge level using the SANWatch software
or the embedded firmware utility.
