Power supply
The power supply bay comes with two 600-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.
Warning! The power supply in this product contains no
user-serviceable parts. There may be more than one power
supply in this product. Refer servicing only to qualified
personnel.
System fan
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 four fan modules. Air enters through the bezel,
passes through the fan bay and electronics bay, and exhausts through
the rear of the chassis. The power supply modules and hot-swap hard
drive bays also come with their own fans which draw air through those
components and through the peripheral bays.
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 or not present. Under
the same fan failure conditions, the general system fault LED on the
front panel is lit.
