More and more servers is Intelligent Platform Management Interface<\/a> (IPMI) capable. Using IPMI you can control, set and query information about\u00c2\u00a0hardware as long as the hardwares baseboard management controller (BMC) is online. Normally the BMC will be online when power is present and IPMI is thus suitable for controlling power to the server itself. Since version 1.5 of the specificatino IPMI also provides support for Serial Over Lan (SOL),\u00c2\u00a0that is redirection of the serial port over a LAN interface. When running an OS that can redirect the console to the serial port, you will be able to log in through the console remotely using SOL and\/or retrieve the console log remotely.<\/p>\n
