	Serial Over Lan (SOL)
Serial Over Lan (SOL)	11

Serial over LAN (SOL) is a packet format and protocol defined in the IPMI v2.0 specification for transmitting serial port data over Ethernet using IPMI over LAN (RMCP+) messages. This two- way redirection of a blade’s serial port data over Ethernet is independent of the operating system or any applications executing on it. The BIOS also supports redirection of its console over serial port, which can be redirected over the network for remote access.

The SOL mechanism, coupled with a SOL client utility executing on a remote node, allows viewing of serial port data from any IPMI v2.0 based, SOL-enabled blade, thus providing a virtual remote terminal server for accessing the blade’s serial port character stream.

Note: 1) This feature is supported on all MPCBL0001N04 boards with TA# C13354-013 (or above) and MPCBL0001F04 boards with TA# C55360-014 (or above) only.

2)The latest BIOS - Version P13-0028 (or above) and IPMC firmware - Version 1.17 (or above) is needed to ensure this feature works.

11.2SOL Architecture

The SOL implementation on the Intel NetStructure® MPCBL0001 blade is based on the definition in Section 15 of the IPMI v2.0 specification.

Serial over LAN (SOL) enables suitably designed blades and servers to transparently redirect serial character stream of a baseboard UART to/from a remote client via LAN over RMCP+ sessions. This enables users at remote consoles to access the serial port of a blade/server and interact with a text-based BIOS console, operating system, command line interfaces, and serial text-based applications.
