A serial console server or serial console concentrator is a device that allows many RS-232 serial ports to be accessible remotely, technically it is a Terminal Server configured in reverse mode. Typically, the device has 8, 16, 32 or 64 serial ports, either DE-9, MMJ or RJ-45-wired, connected to the serial ports of other equipment, such as servers, routers or switches. It is then possible to telnet- (or dial-) in to the serial console server and access any of the ports for out-of-band management. Some more modern servers even include SSH support.

An alternative approach used in some cluster setups is to null-modem wire and Daisy-chain consoles to otherwise unused serial ports on nodes with some other primary function.
