Cisco - Connecting a Terminal to the Console Port on Catalyst Switches
Use a null-modem cable to connect the switch to a remote DCE device, such as a modem or a Data
Service Unit (DSU). Use a straight-through cable to connect the switch to a data terminal equipment
(DTE) device, such as a terminal or a PC.
The console port of the Catalyst 4000 Supervisor Engine I uses a DB-25 connector and supports Data
Terminal Ready (DTR), Data Set Ready (DSR), Clear To Send (CTS), and Request To Send (RTS)
handshake signals. Table G-1

Connecting a Terminal to the Catalyst 4000/4500
Supervisor Engine II/II+/III/IV, 2948G, 2980G, and
4912G
You may configure the Catalyst 4000/4500 series switches from a direct console connection to the
console 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.
Table H-1 lists the switch console port pinouts. Use a straight-through cable to connect the switch to a
DTE device, such as a terminal or a PC.
