Console Port Pin Assignments
The DB-9 serial port on the switch’s front panel is used to connect to the
switch for out-of-band console configuration. The on-board menu-driven
configuration program can be accessed from a terminal or a PC running a
terminal emulation program. The pin assignments used to connect to the
serial port are provided in the following tables.
