drivers, and diagnostic tools are included with your purchase of the server board SE7501HG2.

These references and tools, along with information updates published to Intel’s public support

site, help to minimize downtime if an issue occurs. Below is a summary of references and tools

provided and where they are located.

Tested Hardware and OS List

The Tested Hardware and OS list is located on the web at:

http://support.intel.com/support/motherboards/server/SE7501HG2/testedhw_os.htm. This list

contains a comprehensive list of operating systems and hardware components tested by Intel

with the Intel Server Board SE7501HG2. This list does not contain information about memory,

processors, or non-Intel chassis. It does contain the following:

• PCI cards (Example: RAID controllers, Network Interface Cards, SCSI controllers)

• USB devices

• CD, DVD, floppy drives

• Removable devices

• Hard drives

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)

Intel® Server Board SE7501HG2 Troubleshooting Guide

Revision 1.0

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

http://support.intel.com/support/motherboards/server/SE7501HG2/spec.htm

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.

Revision 1.0

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.
