Intel SE7520JR2 Suppoted Management Features by Tier, Revision 113 C78844-002, Intel Management

Intel® Server Board SE7520JR2 Platform Management

BIOS Console Redirection is intended to accomplish the implementation of VT-UTF8 console redirection support in Intel® server BIOS products. That implementation will meet the functional requirements set forth in the Microsoft Whistler WHQL requirements for headless operation of servers, as well as maintain a necessary degree of backward compatibility with existing Intel server BIOS products, and meet the architectural requirements of Intel server products currently in development.

The server BIOS has a “console” that is intended to interact with a display and keyboard combination. The BIOS instantiates sources and sinks of input/output data in the form of BIOS Setup screens, Boot Manager screens, Power On Self Test (POST) informational messages and hotkey/escape sequence action requests.

If the BIOS determines that console redirection is enabled, it will read the current baud rate and pass this value to the appropriate management controller via the IPMB. Through the redirection capabilities of the BMC on Intel® platforms, this serial port UART input/output stream is further redirected and sent over a platform LAN device as a packetized serial-byte stream. This BMC function is called Serial over LAN, or SOL, and further optimizes space requirements and server management capability. SOL is only supported by the IMM.

5.Platform Management

The Platform Management sub-system on the Server Board SE7520JR2 consists of a micro- controller, communication buses, sensors, system BIOS, and server management firmware. It provides for three different levels of platform management: On-Board Platform Instrumentation based around the National Semiconductor* PC87431M mini-Baseboard Management Controller (mBMC), the Intel® Management Module Professional Edition, and the Intel® Management Module Advanced Edition, which are based on Intel’s “Sahalee” BMC. As shipped, the baseboard comes standard with On-Board Platform Instrumentation. A 120-pin connector on the baseboard provides the interface to the optionally installed Intel Management Modules (IMM).

The following table summarizes the supported features for each management level:
