Power Supply Units

i

The SATA-based RAID subsystems are equipped with two (2) redundant, hot-swappable, 2U, 350W power supply unit (PSUs) modules. The PSU is permanently mounted into a 2U high (dual-level) bracket especially designed to house both the PSU and a cooling module mounted underneath. PSUs can be found on either side of the controller module.

Each PSU comes with a single power socket for power cord plug-in and a single power switch for you to turn the PSU on and off. Each PSU also comes with two embedded cooling fans to provide sufficient airflow to keep the PSU cool. A single LED is used to indicate the PSU sta- tus. A handle at the back of the PSU has been especially designed to enable you to remove the PSU from the subsystem while the system is still online. This should only be done if the PSU has failed and needs to be replaced.

NOTICE!

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

A retention screw at the upper right corner of the PSU module is used to secure the PSU to the enclosure. If the PSU needs to be removed, the retention screw must be removed first. When installing a new PSU module, make sure that the retention screw has been firmly secured.

2.3.6	Cooling Fan Modules
	The SATA-based RAID subsystem is equipped with two 1U single-fan, redundant, hot-swappa-
	ble cooling modules shown in Figure 2.13. One 9.7cm fan is housed in each cooling module.

These modules have been designed to generate a cooling flow from the front to the rear of the subsystem to extract the heat generated by the SATA hard drives. Two of the cooling fan mod- ules are installed directly beneath the PSUs.

Insert the new PSU module into the subsystem Once the previously removed cooling module has been installed, insert the new PSU module into the subsystem. Make sure the extraction lever is in its downright position so that the saddle notches on the lower edges of the handle can lock on to the edge metal brackets along the chassis inner walls.
