The Cisco Catalyst 2950/3550/4000/5000/6000 Series switches have ports that can be configured for either 10BASE-T or 100BASE-T connections.

When connecting the switch to servers, workstations, and routers, it is necessary to use a straight-through cable. When connecting to other switches or repeaters, it is necessary to use a crossover cable. The port status LED will illuminate when both the switch and the connected device are powered up. If the LED is not illuminated, it is possible that one of the devices may not be turned on, there may be a problem with the adapter on the attached device or with the cable, or the wrong type of cable may be in use.

After setting up the basic IP configuration, the switch can be accessed through Telnet, unless security policy precludes Telnet access.

Many applications such as Tera Term, QVT Term, HyperTerminal, PUTTY (Pretty Useful TTY) and SecureCRT, include terminal emulation programs that can be used for console access to a Cisco switch. These applications also provide other access options such as Telnet (TCP port 23) and Secure Shell (TCP port 22).
