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.
