Appendix A: Integration and Usage Tips

When adding or removing components or peripherals from the server board, you must
remove AC power. With AC power plugged into the server board, 5-volt standby is still
present even though the server board is powered off.

Only " Intel
®
Xeon
®
processor 5500 series” with 95 W and less Thermal Design Power
(TDP) are supported on this server board. Previous generation Intel
®
Xeon
®
processors are not supported. “Intel
®
Xeon
®
processor 5500 series" with TDP higher
than 95 W are not supported.

Processors must be installed in order. CPU 1 is located near the edge of the server
board and must be populated to operate the board.

On the back edge of the server board are eight diagnostic LEDs that display a
sequence of amber POST codes during the boot process. If the server board hangs
during POST, the LEDs display the last POST event run before the hang.

Only registered DDR3 DIMMs (RDIMMs) and unbuffered DDR3 DIMMs (UDIMMs) are
supported on this server board. Mixing of RDIMMs and UDIMMs is not supported.

For the best performance, the number of DDR3 DIMMs installed should be balanced
across both processor sockets and memory channels. For example: a Two-DIMM
configuration will perform better than a One-DIMM configuration. In a Two-DIMM
configuration, DIMMs should be installed in DIMM sockets A1 and D1. An Eight-DIMM
configuration (DIMM sockets A1, B1, A2, B2, D1, D2, E1, and E2) will perform better
than a Four-DIMM configuration (DIMM Sockets A1, B1, A2, and B2).

The Intel
®
RMM3 connector is not compatible with the Intel
®
Remote Management
Module (Product Code AXXRMM3 ) or with the Intel
®
Remote Management Module 2
(Product Code AXXRMM2).

Clear COMS with AC power cord plugged. Removing AC power before performing the
CMOS clear operation will cause the system to automatically power up and
immediately power down after the CMOS clear procedure is followed and AC power is
re-applied. If this happens, remove the AC power cord, wait 30 seconds, and then re-
connect the AC power cord. Power up the system and proceed to the <F2> BIOS
setup utility to reset the desired settings.

Normal BMC functionality is disabled with the force BMC update jumper (J8C1) set to
the “enabled” position (pins 2-3). The server should never be run with the BMC force
update jumper set in this position and should only be used when the standard firmware
update process fails. This jumper should remain in the default (disabled) position (pins
1-2) when the server is running normally.

This server board no longer supports rolling BIOS (two BIOS banks) and implements a
BIOS recovery mechanism instead.

When performing normal a BIOS update procedure, the BIOS recovery jumper (J1A1)
must be set to its default position (pins 1-2).
