LED Information
The Intel®Server Board SE7501HG2 includes LEDs that can aid in troubleshooting your
system. A table of these LEDs with a description of their use is listed below.
LED Name Function Location Color Status

Beep Codes
Sometimes when a system is powered on a sequence of ‘beeps’ may be heard during the boot
sequence. These beeps have a code that identifies system or PCI card events. For example,
some Intel®RAID cards have beep codes. Before checking for a system beep code error make
sure the PCI card is not causing the beeping.
System beep codes are generated by the BMC. The BMC generates beep codes upon
detection of the failure conditions listed in the following table. Each digit in the code is
represented by a sequence of beeps whose count is equal to the digit. The most common beep
codes are listed in the table below
Code Reason for Beep
1 Front panel CMOS clear initiated
1-5-1-1 FRB failure (processor failure)
1-5-2-1 No processors installed or processor socket 1 is empty.
1-5-2-3 Processor configuration error (e.g., mismatched VIDs, Processor slot 1 is empty)
1-5-2-4 Front-side bus select configuration error (e.g., mismatched BSELs)
1-5-4-2 Power fault: DC power unexpectedly lost (e.g. power good from the power supply was deasserted)
1-5-4-3 Chipset control failure
1-5-4-4 Power control failure (e.g., power good from the power supply did not respond to power request)

In the case of a Bootblock update, where video is not available for text messages to be
displayed, speaker beeps are necessary to inform the user of errors. For beep codes
associated with a Bootblock update refer to the Intel®Server Board SE7501HG2 Technical
Product Specification located at

3. Questions and Answers
Processor Questions and Answers
Does it matter which processor is populated first?
Yes. The socket for Processor 1 must be populated first. The Processor 1 socket is the closest
to the outside edge of the board and is labeled “CPU1”. The Processor 2 socket is closer to the
center of the board and is labeled “CPU2”. If a single processor is used and is installed in the
Processor 2 socket instead of the Processor 1 socket, this product will not.
The system bus is automatically terminated, which means if a single processor is used, the
empty Processor 2 socket does not require a terminator.
Will the system always boot from Processor 1, even if two processors are installed?
Not necessarily. When two processors are installed, the Intel®Server Board SE7501HG2 will
boot from either processor using a technique called Fault Resilient Booting (FRB). If the primary
processor fails to respond in a designated amount of time during POST, the secondary
processor is used to complete the boot-up sequence.
If a processor error occurs in a single processor configuration, the board will halt during the boot
process and display a message for the user indicating that it is forcing itself to boot from a
potentially bad processor. The system will attempt to continue the boot process after the user
acknowledges the message.
For more information on FRB, refer to the Intel® Server Board SE7501HG2 Technical Product
Specification located on the Intel Support Website
How do I disable hyper-threading?
Hyper-threading can be disabled in BIOS setup, under the “Advanced” menu. Disabling hyper-
threading will cause performance degradation on some applications.
If I only install one processor, what do I do with the standoffs around the Processor 2
socket?
All eight CPU standoffs on the chassis base plate must be installed when the board is being
integrated in a chassis. These standoffs are required even if the system is will be operated with
only a single processor in order to withstand shock and vibration.

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®Server Board SE7501HG2 Quick
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®Server Board SE7501HG2 Quick
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®Server
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®Server Chassis SC5200 650W Hot-Swap Redundant Power
(HSRP).
The following table describes how the fans should be connected on the board when integrated
into the SC5200 450W Base Chassis.

Some of my devices are not recognized under the Windows* 2000 Device Manager. What
might be wrong?
After installing Microsoft* Windows 2000 Advanced Server, the Device Manager might display
unrecognized devices. This is because the operating system does not include all of the drivers
for the Intel®E7501 chipset, on-board NICs, and the SCSI Hot Swap Backplane. Installing the
Intel Chipset Utility (INF files), NIC drivers, and HSBP drivers that are available on the Resource
CD will allow the operating system to properly recognize these devices.
