DIMM Module

 

The controller module comes with a pre-installed 256MB capacity or above DDR RAM DIMM

 

module and can support capacities up to 1GB. The DIMM module is placed in an easily

 

accessed location on the controller board. However, when the DIMM module is being

 

changed, the controller module must be removed from the subsystem chassis.

2.5.6Battery Backup Unit (BBU)

The Li-ION battery backup unit (BBU) (see Figure 2.11) sustains cache memory after a power failure. It is installed on the upper left side of the controller module in the rear subsystem chassis.

 

Fig. 2.10 BBU Module

 

In accordance with international transportation regulations, the BBU is only charged to

 

between 35% and 45% of its total capacity when shipped. Therefore, after powering on the

 

subsystem (see Section 5.4 Power On) the BBU must be charged to its 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 problem with the BBU and you should con-

 

tact your subsystem vendor immediately. While the battery is being charged, the LED on the

 

BBU rear panel and the fifth LED on the rear panel of the controller module will flash slowly.

 

(See Section 4.2.6 BBU Module LED for details on the LED indicators.) You can check the sta-

 

tus of the battery’s charge via Bosch RAIDWatch or the firmware.

2.5.7

Power Supply Units

 

The RAID subsystem is equipped with two (2) redundant, hot-swappable, 460W PSUs, which

are located at the rear of the enclosure. (See Figure 2.6) The PSU is permanently mounted into a 2U (dual-level) bracket especially designed to house both the PSU and a cooling mod- ule, 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 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.
