Processor(S) - Intel SE7501BR2 - Server Board Motherboard Product Manual

Floppy Disk Connector
The floppy disk connector on the server board provides the interface to the floppy disk drive from
the floppy disk controller.
Keyboard and Mouse Connectors
The separate keyboard and mouse connectors, found on the back panel of the server board, are
PS/2-compatible. The keyboard and mouse connectors are interchangeable.

Processor(s)

®
The Intel Server Board SE7501BR2 accommodates one or two Intel Xeon processors with 512KB
L2 Cache via two SKT604 604-pin zero-insertion force (ZIF) sockets. The processors interface
with the system bus at 533 MHz, backwards compatible with 400 MHz. When only one processor
is installed, it should be in the socket labeled CPU1 and the other socket must be empty.
For a complete list of supported processors, see:
http://support.intel.com/support/motherboards/server/SE7501BR2
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 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
Complete thermal solution including a processor wind tunnel (PWT), fan, and heatsink is supplied
with each boxed Intel Xeon processor.
NOTE
Do not install the Processor Wind Tunnel when using the Intel
SC5200 with hot swap redundant power. To install the heat sink you must use
the Retention Mechanisms supplied with the SC5200 chassis. For this chassis,
see the installation instructions beginning on page 47.
Otherwise, install the processor wind tunnels according to the instructions
provided in this document or in the SE7501BR2 Quick Start User's Guide. These
instructions are different than those included with the boxed processor. 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.
