Dual Processor Operation
The Intel Xeon processor interface is dual-processor (DP)-ready. The processor subsystem
includes a single VR (Voltage Regulator) to support both processors. Interrupt generation and
notification for the processors is done by the Advanced Programmable Interrupt Controllers
(APICs) in the ICH3-S and P64H2. When two processors are installed, both processors must be of
identical revision, core voltage, and bus/core speeds.
Boxed Processor Fan Heat Sink
A processor wind tunnel (PWT) is supplied with each boxed Intel Xeon processor. After the
processor and heat sink are installed, install and connect the processor wind tunnels.

NOTES
Heat sink styles vary. If your heat sink has a flat end, the flat surface must be
installed so that it faces the rear of the chassis. See the installation instructions
in Chapter 2.
Do not install the Processor Wind Tunnel when using the Intel
®
Server Chassis
SC5200 with hot swap redundant power. For this chassis, see the installation
instructions beginning on page 46.
When not using the SC5200 with hot swap redundant power, refer to the
instructions in this document, the instructions included with your boxed
processor, or the instructions in the SE7501HG2 Quick Start User’s Guide.
For proper processor cooling, the fan inlet air temperature should be below 45 C.
CAUTION
Clearance is required at each end of the fan heat sink to ensure unimpeded
airflow for proper cooling. Restricting the airflow through the processor heat
sink can cause overheating and subsequent failure of the processor.
