The Intel Server Board SE7520AF2 provides an ideal solution for business-critical database, departmental, and workgroup server solutions. The board offers outstanding performance through support for dual Intel Xeon processors with an 800MHz system bus. In addition, seven independent PCI buses and PCI Express I/O technology provide flexible and scalable I/O, and highly reliable storage is enabled through support for dual-channel Ultra320 SCSI supporting RAID levels 0 and 1 and optional integrated Intel RAID providing RAID levels 0, 1, 5, 10, and 50.
J1D1: The Intel Server Board SE7520AF2 provides an 11-pin single inline header, located on the edge of the baseboard next to the Front Panel connector, this connector provides a total of three 3-pin jumper blocks that are used to configure several system recovery and update options.
Supported Processors: The Intel Server Board SE7520AF2 is designed to support one or two Intel Xeon processors with 1MB or 2MB L2 Cache with frequencies starting at 2.8 GHz using 90 nanometer technology and utilizing an 800 MHz front side bus. Previous generations of the Intel Xeon processor are not supported for use on Intel Server Board SE7520AF2. When two processors are installed, both must be of identical revision, core voltage, cache size, and bus/core speed. When only one processor is installed, it should be populated into the socket labeled "CPU_1" with the other CPU socket remaining unpopulated.
Memory: DIMMs must be populated beginning with the socket furthest away from the MCH (i.e.DIMM 1B and DIMM 1A). DIMMs must also be identical within the same bank. For example, the DIMM in socket DIMM 1A must be identical to the DIMM in socket DIMM 1B
Intel Management Module Connector: A 120-pin IMM Connector (J3J1) is included on the baseboard to support the optionally installed "Standard" or "Advanced" Intel Management Modules.
To support the tiered management model, the Intel Server Board SE7520AF2 supports two different management controllers. Integrated onto the baseboard is the National Semiconductor 87431x Mini-BMC (mBMC) to provide the functionality of the onboard platform instrumentation management tier. The Standard and Advanced modules electrically replace the mBMC with the more full featured "Sahalee" microcontroller. Sahalee is a custom ARM7-TDMI based microcontroller designed for baseboard management applications on Intel Server baseboards.
