Cisco - Connecting a Terminal to the Console Port on Catalyst Switches
Connecting a Terminal to Catalyst 2948G-L3,
4908G-L3, and 4840G Series Switches
You may configure the Catalyst switch routers from a direct console connection to the console port or
remotely through its management port.
Use the RJ-45-to-RJ-45 rollover cable and RJ-45-to-DB-9 female data terminal equipment (DTE)
adapter (labeled "Terminal") to connect the console port to a PC running terminal emulation
software.
If you are using a direct console connection, configure your terminal emulation program for 9600
baud, 8 data bits, no parity, and 1 stop bit.
Console Port Pinouts
The console port is an RJ-45 receptacle. Data Terminal Ready (DTR) and Data Set Ready (DSR)
handshake signals are supported. The Request To Send (RTS) signal tracks the state of the Clear To Send
(CTS) signal.
