Console Port Pin Assignments
The DB-9 serial port on the IronPoint 250 is used to connect to the access point for out-of-band
management. The access point’s command-line interface can be accessed from a terminal or a PC
running a terminal emulation program.
Connect the console cable (included) to the RS-232 console port to access the command-line
interface. You can manage the access point using the console port, the Web interface, or SNMP
management software. Refer to the Foundry IronPoint 250 User Guide for more information.
The pin assignments used to connect to the console port are described in the following figure and
table.
