1.2.5 Power Supply Units

PN: IFT-9272CPSU-0011

The SATA-based EonStor 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 status. 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.

NOTE:

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.
