Console Port

Both the Catalyst 4948E and the Catalyst 4948E-F switches can be accessed through a serial console
port located on the chassis front panel. The console port is 10/100/1000BASE-T port that uses an RJ-45
connector. The console port allows you to access the switch either locally (with a console terminal or
PC) or remotely (with a modem).
