Microsoft Windows Logo Program System and Device Requirements — 52
For use with the headless server capabilities of Windows, x86-based systems must provide a legacy serial port that is addressable at either COM1 (03F8h) or COM2 (02F8h), configured to the default settings of 9600 bps, 8 bits, no parity, and 1 stop bit. This port must also comply with the requirements for legacy serial ports.
A188.8.131.52 x86-based system that implements management service processor and external serial headless capability supports required external serial port and remote system reset
Required if the service processor exposes a UART interface via hardware to the operating system or if the serial port is the only full-time management connection
This requirement addresses the minimum capabilities needed for headless server support with service processors that provide external serial capabilities.
Management service processors that provide both serial and LAN-based full-time management connections but do not provide an internal 16550 UART hardware interface (i.e. Service Processor does not provide a serial port interface or the serial port interface is provided by a Windows driver and is not available before Windows is loaded) must provide at least the capabilities in A184.108.40.206 or must provide the capabilities outlined in A220.127.116.11 for the alternate LAN-based management connection.
A18.104.22.168 x86-based system with management service processor and external serial headless capability supports BIOS redirection of console output, plus serial port and serial headless cabling requirements
Systems with service processors that provide external serial support must meet the requirements in A22.214.171.124 plus the following additional requirements.
A126.96.36.199 x86-based system that implements a management service processor but no external serial connection meets reset and display redirection requirements
Required if system implements headless support with a management service processor.
For enhanced out-of-band management capabilities, systems can provide a management service processor. This processor can enable such advanced capabilities as remote system reset and assistance with disaster recovery.
Note that an x86-based system is not required to provide a management service processor. This requirement addresses the minimum capabilities needed for headless server support with service processors but no external serial connection capabilities.
The management service processor must support a remote system reset capability. This capability may be provided through OEM-specific mechanisms.
A188.8.131.52 x86-based headless system meets USB controller and port requirements
If you implement headless support in one of the following ways, a USB controller and port in the server is not required:
System that implements headless capabilities without management service processor provides serial headless support.
System that implements management service processor and external serial headless capability supports required external serial port and remote system reset.
System that implements a management service processor but no external serial connection meets reset and display redirection requirements.
