CAUTION Because all hard drives have different cooling, power, and vibration characteristics, Intel has validated specific hard drive types in the SPSH4 server. To see a list of validated manufacturers and hard drive types, go to: http://support.intel.com/support/motherboards/server/ssh4/spsh4/compat.htm Power Supplies 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. 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 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. 136 Intel SPSH4 Server Platform Product Guide

Intel SPSH4 Server Platform Product Guide
CAUTION
Because all hard drives have different cooling, power, and vibration
characteristics, Intel has validated specific hard drive types in the SPSH4
server.
To see a list of validated manufacturers and hard drive types, go to:
Power Supplies
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.
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 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.
