Power Supplies
The power supply bay comes with two 430-W power supply modules and can accommodate a third
module for redundancy. The modules connect through the power distribution board (PDB) and
auto-sense input voltage. The power redundant (2+1) configuration allows you to hot-swap a failed
power supply without interrupting normal system operation.
System Cooling
CAUTION
All access covers must be on the system for proper cooling.
To ensure that all components remain within specification under all system
environmental conditions, do not exceed five minutes for hot swapping of
fans or power supplies.
The server comes with six fans in a redundant (5+1) configuration. This redundant configuration
allows you to hot-swap a failed fan module without interrupting normal system operation. Air
enters through the bezel, passes through the system components, and exhausts through the rear and
left side of the chassis.
Under normal system conditions, the fans run at a slower, quieter speed. If a fan failure is sensed, a
fan is not detected, or ambient temperature exceeds a certain limit, the fan speed is set to high.
LEDs indicate if individual fans are inoperative. Under the same fan failure conditions, the general
system fault LED on the front panel is lit.
