RAID Subsystem
2.5.5 | DIMM Module |
| The controller module comes with a |
| 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
| 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, |
are located at the rear of the enclosure. (See Figure 2.6) The PSU is permanently mounted into a 2U
As shown in Figure 2.11, each PSU comes with a single power socket for power cord
When any power supply failure occurs, such as
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.
