Serial over LAN (SOL) is a mechanism that enables the input and output of the
serial port of a managed system to be redirected over
IP.
Details
On some managed systems, notably
blade server
A blade server is a stripped-down server computer with a modular design optimized to minimize the use of physical space and energy. Blade servers have many components removed to save space, minimize power consumption and other considerations, whil ...
systems, the serial ports on the managed computers are not normally connected to a traditional serial port socket. To allow users to access applications on these computers via the serial port, the
input/output
In computing, input/output (I/O, or informally io or IO) is the communication between an information processing system, such as a computer, and the outside world, possibly a human or another information processing system. Inputs are the signals ...
of the serial port is redirected to the network. For example, a user wishing to access a blade server via the serial port can

Telnet is an application protocol used on the Internet or local area network to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection. User data is interspersed in-band with Telnet control i ...

A network address is an identifier for a node or host on a telecommunications network. Network addresses are designed to be unique identifiers across the network, although some networks allow for local, private addresses, or locally administere ...
and log in. On the blade server the login will be seen as coming through the serial port.
SOL is implemented as a payload type under the
RMCP+ protocol in
IPMI.
