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).

Table B-14lists the console port pinouts.

Table B-14		Console Port Pinouts
Pin	Signal		Direction	Description
1	RTS		output	request to send
2	DTR		output	data terminal ready
3	TXD		output	transmit data
4	GND		—	—
5	GND		—	—
6	RXD		input	receive data
7	DSR		input	data set ready
8	CTS		input	clear to send
