PSU Module Overview

•

•

•

Two (2) redundant PSU modules: The RAID subsystem is preinstalled with two (2) 460W, fully redundant, hot-swappable PSU modules. These modules are located at the rear of the subsystem.

PSU bracket: Each PSU module is permanently mounted in a two-level steel bracket, cre- ating a single unit. The PSU is located in the upper level and a removable cooling module is mounted in the lower level. When removing the PSU from the subsystem, the cooling module is also being removed.

PSU printing mark: Before you insert a new PSU, be sure that it has the same printing mark on its handle as that shown on the handle of a remaining PSU. Double-check to avoid mixing a PSU of previous series. (See Figure 6.10)

•Immediate replacement: When a PSU fails, it should be replaced immediately. However, do not remove the PSU module unless a replacement is readily available. Removing a PSU without a replacement will cause severe disruptions to the internal airflow and the sub- system will overheat, possibly causing irreparable damage to some of the subsystem components.

6.5.2Replacing the PSU Module

CAUTION!

Although the PSU modules are fully redundant, it is not advisable to run the RAID subsystem with a single PSU module for an extended period of time. If the second PSU module fails, the subsystem will be shut down.

To replace a PSU, please follow these steps:

1.Turn off the PSU. Using the power switch located at the top of the rear panel, directly above the PSU module. (See Figure 6.11)

2.Remove the power cable that connects the RAID subsystem to the main power source. The power socket is found on the left side of each power supply module. (See Figure 6.11)
