Intel® Server Board SE7501HG2
Which way should the processor wind tunnels be installed?
When configuring the board in a dual-processor configuration, both processor wind tunnels and
their fans must be installed with the same orientation. Proper installation requires that both fans
push air through the processor wind tunnel. Refer to the Intel
Start User's Guide for installation instructions.
Memory Questions and Answers
What are the memory / DIMM requirements?
The SE7501HG2 supports only registered DDR266 SDRAM memory. DIMMs must be installed
in pairs and must be populated by bank, starting with Bank1 (DIMM1A and DIMM1B contiguous
sockets). Although the board allows the user to mix various sizes of DIMMs between banks,
DIMMs must be identical within the banks. Memory Bank1 is the pair of DIMMs located closest
to the edge of board; refer to the board drawing on the Intel
Start User's Guide.
On Board Component Questions and Answers
Which 10/100/1000 NIC connector is for server management?
The server board SE7501HG2 board provides two RJ45 connectors for the on-board Network
Interface Controllers. The two NICs are stacked with NIC1 on the bottom. NIC1 is the
designated Server Management NIC.
How do I disable the integrated components?
Onboard controllers can be disabled through the server board BIOS setup. To enter BIOS
setup, press F2 when prompted during the boot up process.
How should the system fans be connected?
The SE7501HG2 board ships with five system fan headers. Sys Fan 1, Sys Fan 2, Sys Fan 3,
and Sys Fan 4 are used when integrating the server board SE7501HG2 in the Intel
Chassis SC5200 Base. Sys Fan 5 is used in addition to Sys Fans 1 through 4 when the server
board is integrated in the Intel
(HSRP).
The following table describes how the fans should be connected on the board when integrated
into the SC5200 450W Base Chassis.
