SSG 20 Hardware Installation and Configuration Guide AUX Port The auxiliary (AUX) port is an RJ-45 serial port wired as data terminal equipment (DTE) that can be connected to a modem to allow remote administration. We do not recommend using this port for regular remote administration. The AUX port is typically assigned to be the backup serial interface. The baud rate is adjustable from 9600 bps to 115200 bps and requires hardware flow control. Use a straight-through cable when connecting to
