Functional Architecture Intel® Server Boards S5520HC and S5500HCV TPS

Revision 1.2

Intel order number E39529-009

3.2 Processor Support

The Intel

Server Boards S5520HC and S5500HCV support one or two Intel

Xeon

Processor

5500 Series with a 4.8 GT/s, 5.86 GT/s, or 6.4 GT/s Intel

QPI link interface and Thermal

Design Power (TDP) up to 95 W.

The server boards do not support previous generations of the Intel

Xeon

Processors.

For a complete updated list of supported processors, see:

http://support.intel.com/support/motherboards/server/S5520HC/

. On the Support tab, look for

“Compatibility” and then “Supported Processor List”.

Note: Supports only the Intel

Xeon

Processor 5500 Series with 4.8 GT/s, 5.86 GT/s, or 6.4

GT/s Intel

QPI link interface.

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

QPI/core speed.

3.2.2 Mixed Processor Configurations.

The following table describes mixed processor conditions and recommended actions for the

Intel

Server Boards S5520HC and S5500HCV. 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.
