Power Supply Placement
The redundant power supply, located in the back of the chassis, consists of
one frame and two identical AT power modules. The LED indicators light
when both the input and output voltages are stable, and dim when either
the input or output voltage fails. A button located on the bottom-left corner
of the power supply disables the sounding of the audible alarm.
Replacing One Power Supply Module
Remove all cords connecting to the failed power module. The power sup-
ply module is secured by two spring clips (as circled above) and two hooks.
To remove the power module, use a screwdriver to push in the clips and
then slide the power module out. Insert a working power supply module.
Removing the Entire Power Supply Unit
Unplug all cords connecting to the power supply unit. Remove the eight
screws securing the power unit. Remove the side panel and then push the
power unit out of the chassis.
The alarm will sound if any of the power supply unit is not
turned on before the system is powered on.
