Serial Over LAN (SOL) for EPSD Server Hardware
Serial Over LAN (SOL) is a mechanism that enables redirection of serial character stream from UART (Universal Asynchronous Receiver Transmitter aka Serial Port) to a LAN using IPMI RMCP+ session on a managed server. It provides a means to manage a server remotely by using a Command-Line Interface (CLI) over a Telnet or Secure Shell (SSH) connection. SOL provides console redirection for both BIOS as well as the server operating system. The advantages of SOL include the following: remote administration without keyboard, video, or mouse (for example, headless servers), reduced cabling by removing the need for a serial connector, standard Telnet interface that eliminates the need for special client software.
