ies 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 is a prob-

 

lem with the BBU module and you should contact your subsystem vendor immediately. While

 

the battery is being charged, the LED on the BBU rear panel and the sixth LED on the rear

 

panel of the controller module will flash. (See Section 4.2.5 BBU Module LED and

 

Section 4.2.6 PSU LEDsfor details on the LED indicators.)

 

You can check the status of the battery’s charge via RAIDWatch or the firmware utility screen.

Power Supply Units

i

The RAID subsystem is equipped with two (2) redundant, hot-swappable, 350W PSUs, which are accessed through the rear of the enclosure. 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.

NOTICE!

Hot-swapping the PSU also removes the cooling module at the lower slot.

As shown in Figure 2.11, each PSU comes with a single power socket for power cord plug-in, and a power switch on the right 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 you to remove the PSU from the subsystem while the subsystem is online. This should only be done if the PSU has failed and needs to be replaced.

A retention screw at the top of the PSU module secures the PSU to the enclosure. To remove the PSU, the retention screw must be removed first. When installing a new PSU module, make sure that the retention screw has been firmly secured.

Cooling Modules

 

The two subsystem models are all equipped with three (3) 1U, single-fan, hot-swappable cool-

ing modules. They are installed in the cooling module slots located underneath the controller module and PSU modules (see Figure 2.12.) The cooling fans operate at two (2) fan speed lev- els. When the subsystem is running in normal ambient temperature, the fans operate at the lower speed. When the upper temperature threshold is exceeded, the fans automatically raise
