Intel® Workstation System SC5650SCWS TPS Functional Architecture

Revision 1.2

Intel order number: E81822-002

3.1.3 Enterprise South Bridge Interface (ESI)

One x4 ESI link interface that supports the PCI Express* Gen1 (2.5 Gbps) transfer rate for

connecting Intel

ICH10R in the Intel

Workstation System SC5650SCWS.

3.1.4 Manageability Engine (ME)

An embedded ARC controller is within the IOH providing the Intel

Server Platform Services

(SPS). The controller is also commonly referred to as the Manageability Engine (ME).

3.1.5 Controller Link (CL)

The Controller Link is a private, low-pin count (LPC), low power, communication interface

between the IOH and the ICH10 portions of the Manageability Engine subsystem.

3.2 Processor Support

The Intel

Workstation System SC5650SCWS supports one or two Intel

Xeon

Processor 5500

Series or Intel

Xeon

Processor 5600 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 130 W.

The workstation 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/S5520SC/

. On the Support tab, look for

“Compatibility” and then “Supported Processor List”.

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 workstation 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

Workstation System SC5650SCWS. Errors fall into one of three categories:

z 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 must replace

the faulty part and restart the system.
