1.2.6 Power Supply Units
PSU Canister
The subsystem is equipped with two (2) redundant, hot-swappable,
350W PSUs, which are located at the enclosure’s rear section. The
PSU is permanently mounted into a 2U canister especially designed
to contain both the PSU and a cooling module. If the PSU is removed,
the cooling module is also removed.
As shown in the figure above, each PSU comes with a power socket
for power cord connection and an on/off power switch. A single LED
indicates the PSU status. When a PSU failure occurs, the LED is lit
constantly red. A handle above the PSU enables you to safely
retrieve or install the PSU into the chassis.
A retention screw helps secure the PSU within the module bay. To
remove the PSU, the retention screw must be removed first. After you
install a PSU, make sure the retention screw is firmly secured.
For detailed specifications of the power supply, please refer to
Appendix A.
