Chapter 1: Introduction Special Features Recovery from AC Power Loss Basic I/O System (BIOS) provides a setting for you to determine how the system will respond when AC power is lost and then restored to the system. You can choose for the system to remain powered off (in which case you must press the power switch to turn it back on), or for it to automatically return to a power-on state.
B1SA4-2750F/B1SA4-2550F Motherboard User’s Manual This feature is available when the system is used with Supero Doctor III in the Windows OS environment or used with Supero Doctor II in Linux. Supero Doctor is used to notify the user of certain system events. For example, you can also configure Supero Doctor to provide you with warnings when the system temperature, CPU temperatures, voltages and fan speeds go beyond predefined thresholds.
Chapter 1: Introduction Advanced Power Management Intel Intelligent Power Node Manager (NM) ® The Intel Intelligent Power Node Manager (IPNM) provides your system with ® real-time thermal control and power management for maximum energy efficiency. Although IPNM Specification Version 1.5 is supported by the BMC (Baseboard Management Controller), your system must also have IPNM-compatible Manage- ability Engine (ME) firmware installed to use this feature. Manageability Engine (ME) The Manageability Engine, which is an ARC controller embedded in the IOH (I/O Hub), provides Server Platform Services (SPS) to your system.

CAUTION Exercise extreme care when installing or removing DIMM modules to prevent any possible damage. Note: Check the Supermicro website for a list of memory modules that have been validated with the B1SA4-2750F/B1SA4-2550F motherboard. How to Install SODIMMs Each of the four nodes has its own memory bank. Populate Channel A first, the Channel B.
Chapter 2: Installation Memory Population Guidelines When installing memory modules, the SODIMM slots should be populated in the fol- lowing order: DIMMA1, DIMMB1. • Always use DDR3 SODIMM modules of the same size, type and speed. • Mixed DIMM speeds can be installed. However, all DIMMs will run at the speed of the slowest DIMM.
B1SA4-2750F/B1SA4-2550F Motherboard User’s Manual The SO DIMM Socket Align Position the SO DIMM module's bottom key so it aligns with the receptive point on the slot. Insert the SO DIMM module vertically at about a 45 degree Press down until the module angle.
Chapter 2: Installation Motherboard Installation All motherboards have standard mounting holes to fit different types of chassis. Make sure that the locations of all the mounting holes for both motherboard and chassis match. Although a chassis may have both plastic and metal mounting fas- teners, metal ones are highly recommended because they ground the motherboard to the chassis.

Chapter 3: Troubleshooting Chapter 3 Troubleshooting Troubleshooting Procedures Use the following procedures to troubleshoot your system. If you have followed all of the procedures below and still need assistance, refer to the ‘Technical Support Procedures’ and/or ‘Returning Merchandise for Service’ section(s) in this chapter. Always disconnect the AC power cord before adding, changing or installing any hardware components.
1. Make sure that the SODIMM modules are properly installed and fully seated in the slots. 2. You should be using memory recommended by Supermicro. Also, it is recom- mended that you use the memory modules of the same type and speed for all DIMMs in the system.
Before contacting Technical Support, please make sure that you have followed all the steps listed below. Also, Note that as a motherboard manufacturer, Supermicro does not sell directly to end users, so it is best to first check with your distributor or reseller for troubleshooting services.
Answer: It is recommended that you do not upgrade your BIOS if you are not experiencing any problems with your system. Updated BIOS files are located on our website at http://www.supermicro.com/support/bios/. Please check our BIOS warning message and the information on how to update your BIOS on our web site.
You can obtain service by calling your vendor for a Returned Merchandise Authorization (RMA) number. For faster service, you may also obtain RMA authorizations online (http://www.supermicro. com/support/rma/). When you return the motherboard to the manufacturer, the RMA number should be prominently displayed on the outside of the shipping carton, and mailed prepaid or hand-carried.
When an option is selected in the left frame, it is highlighted in white. Often a text message will accompany it. (Note: the AMI BIOS has default text messages built in. Supermicro retains the option to include, omit, or change any of these text messages.) The AMI BIOS setup utility uses a key-based navigation system called "hot keys".
Flashing the wrong BIOS can cause irreparable damage to the system. In no event shall Supermicro be liable for direct, indirect, special, incidental, or consequential dam- ages arising from a BIOS update. If you have to update the BIOS, do not shut down or reset the system while the BIOS is updating.
