3.2.1

Processor Population Rules

You must populate processors in sequential order. Therefore, you must populate Processor
socket 1 (CPU 1) before processor socket 2 (CPU 2).
When only one processor is installed, it must be in the socket labeled CPU1, which is located
near the rear edge of the server board. When a single processor is installed, no terminator is
required in the second processor socket.
For optimum performance, when two processors are installed, both must be the identical
revision and have the same core voltage and Intel

Mixed Processor Configurations.

The following table describes mixed processor conditions and recommended actions for the
®
Intel Server Boards S5520HC, S5500HCV and S5520HCT. Errors fall into one of three
categories:
Halt: If the system can boot, it pauses at a blank screen with the text
"Unrecoverable fatal error found. System will not boot until the error is resolved" and
"Press <F2> to enter setup", regardless of if the "Post Error Pause" setup option is
enabled or disabled. After entering setup, the error message displays on the Error
Manager screen, and an error is logged to the System Event Log (SEL) with the
error code. The system cannot boot unless the error is resolved. The user needs to
replace the faulty part and restart the system.
Pause: If the "Post Error Pause" setup option is enabled, the system goes directly to
the Error Manager screen to display the error and log the error code to SEL.
Otherwise, the system continues to boot and no prompt is given for the error,
although the error code is logged to the Error Manager and in a SEL message.
Minor: The message is displayed on the screen or on the Error Manager screen.
The system continues booting in a degraded state regardless of if the "Post Error
Pause" setup option is enabled or disabled. The user may want to replace the
erroneous unit.
