Intel® Server Board SE7501HG2 Troubleshooting Guide
Revision 1.0
8
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

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.
