NOTE:
According to supplier cell pack specification, the temperature range over
which the battery can be charged is 0
°
C to 45
°
C. Charging the battery at
temperatures outside of this range may cause the battery to become hot
or to break. Charging the battery outside of this temperature range may
also harm the performance of the battery or reduce the battery's life
expectancy.
When a room temperature reaches 30
°
C or higher, the internal
subsystem temperature may go up to 45
°
C. To protect the battery cell,
the BBU will enter "thermal shutdown" status to disable battery charge,
however the BBU discharge function is still maintained for sustaining
cache memory once the power is shutdown.
1.2.7 PSUs
Figure 1-11: PSU Module
PN: GHDX2-9273ECPSU
The GHDX2-2430S-16F4D is equipped with two (2) redundant, hot-
swappable, 530W PSUs, which are located at the rear of the enclosure. (See
Figure 1-5
) The PSU is permanently mounted into a 2U (dual-level) bracket
especially designed to house both the PSU and a cooling module, which is
mounted in the lower part of the 2U bracket. Hot-swapping the PSU requires
the removal of the cooling module.
As shown in
Figure 1-11
, each PSU comes with a single power socket for
power cord plug-in, and a power switch on the left to turn the subsystem on
and off. Two (2) embedded cooling fans provide sufficient airflow to keep
the PSU cool. A single LED indicates the PSU status. When any power
supply failure occurs, such as over-voltage or fan failure, the LED shines
red. A handle at the back of the PSU has been especially designed to enable
