Intel®Server Boards S2400LP TPS Appendix A: Integration and Usage Tips 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-V standby is still present even though the server board is powered off.  This server board supports The Intel® Xeon® Processor E5-2400 product family with a Thermal Design Power (TDP) of up to and including 95 Watts. Previous generations of the Intel® Xeon® processors are not supported.  Processors must be installed in order. CPU 1 must be populated for the server board to operate.  The server board includes a pre-installed CPU power cable harness. The cable harness must be installed and fully seated in each connector for the server board to operate.  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.  This server board only supports registered DDR3 DIMMs (RDIMMs) and unbuffered DDR3 DIMMs (UDIMMs). 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 performs better than a one-DIMM configuration. In a two-DIMM configuration, DIMMs should be installed in DIMM sockets A1 and D1. A six-DIMM configuration (DIMM sockets A1, B1, C1, D1, E1, and F1) performs better than a three-DIMM configuration (DIMM sockets A1, B1, and C1).  The Intel® Remote Management Module 4 (Intel® RMM4) connector is not compatible with any previous versions of the Intel® Remote Management Module (Product Order Code - AXXRMM, AXXRMM2, AXXRMM3).  Clear the CMOS with AC power cord plugged. Removing the AC power before performing the CMOS clear operation causes 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 BIOS Setup utility to reset the desired settings.  Normal BMC functionality is disabled with the BMC Force 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 normal BIOS update procedure, the BIOS recovery jumper must be set to its default position (pins 1-2).
