DB9 Serial Port Pin Description
The DB9 serial port on the switch’s rear panel is used to
connect the switch to a management device. The on-board
menu-driven configuration program can be accessed from a terminal, a PC
running a terminal emulation program, or from a remote location via a modem
connection. You can use the management port to configure port settings (e.g.,
enabled or disabled), or to update device firmware. The pin assignments used to
connect various device types to the switch's management port are provided in
the following tables.
