Console Port Pin Assignments
The DB-9 serial port on the switch’s rear panel is used to connect to the

configuration program can be accessed from a terminal, a PC running a
terminal emulation program, or from a remote location via a modem
connection. The pin assignments used to connect to the serial port are
