Chapter 1: Introduction
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, the actual charge time will extend the expected charge
time.
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.
1.2.5 PSUs
Figure 1-20: PSU
PN: IFT-9273ECPSU
The F16F series subsystem is equipped with two (2) redundant, hot-
swappable, 530W PSUs, which are located at the rear of the enclosure. (See
Figure 1-12
) The PSU is permanently mounted into a 2U canister
especially designed to house both the PSU and a cooling module, which is
mounted at the rear end of the 2U bracket. When a PSU is removed from
the chassis, the cooling module is also removed.
As shown in
Figure 1-20
, each PSU comes with a single power socket for
power cord plug-in and a power switch to turn the subsystem on and off. A
single LED indicates the PSU status. When a power supply failure occurs,
such as over-voltage, the LED is lit constantly red. An extraction handle at
the rear of the PSU enables you to remove the PSU from the subsystem.
This should only be done if the PSU has failed and needs to be replaced.
