EonStor DS S48 Series Hardware Manual
1.5
Power Supply Unit (PSU)
The system is equipped with three redundant, hot-swappable, 530W PSUs at the
rear section of the chassis.
Each PSU comes with a (1) power socket and built-in (2) cooling modules to provide
sufficient airflow. A (3) single LED indicates the PSU status. When a power supply
failure occurs, the LED will light up red. The built-in cooling module contains two
fans and their statuses are indicated by the (4) cooling module LEDs. The PSU is
secured by a (5) retention screw on the (6) extraction handle at the rear of the PSU,
to the enclosure. Should any of the LEDs light up red, please arrange for a
replacement immediately as a failed PSU will result in the redundancy capability of
the system and failed cooling will cause the system to overheat, resulting in
instability issues.
