Appendix A: Integration and Usage Tips
When adding or removing components or peripherals from the server board, AC power must be
removed. With AC power plugged into the server board, 5-volt standby is still present even
though the server board is powered off.
When two processors are installed, both must be of identical revision, core voltage, and bus/core
speed. Mixed processor steppings is supported. However, the stepping of one processor can not
greater then one stepping back of the other.
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 four diagnostic LEDs which display a sequence of red,
green, or amber POST codes during the boot process. If the server board hangs during POST,
the LEDs will display the last POST event run before the hang.
Only Fully Buffered DIMMs (FBD) are supported on this server board. For a list of supported
memory for this server board, see the Intel
®
Server Board S5000PAL / S5000XAL Tested
Memory List.
For a list of Intel supported operating systems, add-in cards, and peripherals for this server board,
see the Intel
®
Server Board S5000PAL / S5000XAL Tested Hardware and OS List.
Only Dual-Core Intel
®
Xeon
®
processors 5000 sequence, with system bus speeds of
667/1066/1333 MHz are supported on this server board. Previous generation Intel
®
Xeon
®
processors are not supported.
For best performance, the number of DIMMs installed should be balanced across both memory
branches. For example: a four DIMM configuration will perform better than a two DIMM
configuration and should be installed in DIMM Slots A1, B1, C1, and D1. An eight DIMM
configuration will perform better then a six DIMM configuration.
There are no population rules for installing a single low profile add-in card in the 2U LP riser card;
a single add in card can be installed in either PCI Express* slot. While each slot can
accommodate a x8 card, each slot will only support x4 bus speeds.
For the 2U PCI-X* (passive) riser card, add-in cards should be installed starting with the top slot
first, followed by the middle, and then the bottom. Any add-in card populated in the bottom PCI
slot will cause the bus to operate at 66MHz.
Each PCI slot on the 2U PCI-X* (active) riser card operates on an independent PCI bus.
Therefore, using an add-in card that operates below 133MHz will not affect the bus speed of the
other PCI slots.
The IDE connector on this server board is NOT a standard 40-pin IDE connector. Instead, this
connector has an additional 4 power pins over and above the standard 40 I/O pins. The design
intent of this connector is to provide support for a slim-line optical drive only.
Removing AC Power before performing the CMOS clear operation will cause the system to
automatically power up and immediately power down after the procedure is followed and AC
power is re-applied. Should this occur, remove the AC power cord again, wait 30 seconds, and
re-install the AC power cord. Power up system and proceed to the <F2> BIOS setup utility to
reset desired settings.
Normal BMC functionality is disabled with the force BMC update jumper 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.
When performing a BIOS update procedure, the BIOS select jumper must be set to its default
position (pins 2-3).
When AC power is applied to the server, a 25-30 second delay is necessary to initialize the BMC.
During this initialization period, the Power Button functionality is disabled.
