Intel® Server Board SE7520JR2
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.

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:
IPMI Messaging, Commands, and Abstractions
Baseboard Management Controller (BMC)
Sensors
Sensor Data Records (SDRs) and SDR Repository
FRU Information
Autonomous Event Logging
System Event Log (SEL)
BMC Watchdog Timer, covering BIOS and run-time software
