For information on how to connect a terminal to a Catalyst fixed configuration switch, refer to Connecting a Terminal to the Console Port on Catalyst Switches. If you have not already done so, connect a PC to the console port of the switch. The Catalyst fixed configuration switches that this document describes include the 2940, 2950/2955, 2970, 3550, 3560, 3750 and the 3750 Metro series switches. This document explains how to recover Cisco Catalyst fixed configuration switches from a corrupt or missing system image or an incorrectly set boot variable.
