C RS-232 PORTS: For connection to switched devices. Standard DB9 connectors configured as DTE ports. The RS-232 ports are similar to a standard serial port on a PC. When connecting a modem, use a standard serial cable. When connecting a PC or other DTE device use a null modem cable. 
  Port 1 is used for communication during set-up and configuration. When the unit is initialized to defaults, Ports 1 and 2 are the only ports with access to All (Administrator) commands. 
  Port 1 can either be connected to a PC or modem. Connection to a modem allows control by a remote PC.
