Technical Product Specification

Intel® Server Board S2400EP TPS Product Architecture Overview
Revision 2.0 Intel order number G50763-002
19
When using a single processor configuration, the processor must be installed into the
processor socket labeled “CPU_1”.
When two processors are installed, the following population rules apply:
 Both processors must be of the same processor family.
 Both processors must have the same number of cores.
 Both processors must have the same cache size for all levels of processor cache
memory.
 Processors with different speeds can be mixed in a system, given the prior rules are met.
If this condition is detected, all processor speeds are set to the lowest common
denominator (highest common speed) and an error is reported.
 Processors which have different Intel
®
Quickpath* (QPI) Link Frequencies may operate
together if they are otherwise compatible and if a common link frequency can be
selected. The common link frequency would be the highest link frequency that all
installed processors can achieve.
 Processor stepping within a common processor family can be mixed as long as it is
listed in the processor specification updates published by Intel Corporation.
3.1.3 Processor Initialization Error Summary
The following table describes mixed processor conditions and recommended actions for all
Intel
®
server boards and Intel
®
server systems designed around the Intel
®
Xeon
®
processor E5-
2400 product family and Intel
®
C600 chipset product family architecture. The errors fall into one
of the following two categories:
Fatal: 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 whether the “Post Error Pause” setup option is enabled or disabled.
When the operator presses the <F2> key on the keyboard, the error message is displayed on
the Error Manager screen, and an error is logged to the System Event Log (SEL) with the
POST Error Code.
The system cannot boot unless the error is resolved. The user needs to replace the faulty part
and restart the system.
For Fatal Errors during processor initialization, the System Status LED will be set to a steady
Amber color, indicating an unrecoverable system failure condition.
Major: If the “Post Error Pause” setup option is enabled, the system goes directly to the Error
Manager to display the error, and logs the POST Error Code to SEL. Operator intervention is
required to continue booting the system.
Otherwise, if “POST Error Pause” is disabled, the system continues to boot and no prompt is
given for the error, although the Post Error Code is logged to the Error Manager and in a
SEL message.
