The Opengear IM4248 Infrastructure Manager is a network console server with 48 8P8C modular serial ports located on the front
They are three variations on the serial port pinout available: "Opengear Classic/Avocent/Equinox," and "Avocent/Cyclades," and "Cisco." The unit I have is an Opengear Classic model.
