4-9TroubleshootingRestoring the Factory Default ConfigurationTroubleshootingRestoring the Factory DefaultConfigurationAs part of your troubleshooting process on the switch, it may become neces-sary to return the switch to the factory default settings. This process momen-tarily interrupts the switch operation, clears any passwords, clears the consoleevent log, resets the network counters to zero, performs a complete self test,and reboots the switch into its factory default configuration including deletingthe IP address, if one is configured.N o t e This process removes all switch configuration changes you have made fromthe factory default settings. This includes, for example, configuration ofVLANs, Spanning Tree, trunks, and stacking. Returning the configuration ofthese features to their factory default settings (usually disabling them) mayresult in network connectivity issues.If the switch has a valid configuration, and you are restoring the factory defaultsettings for a reason other than configuration problems, you should save theswitch configuration prior to performing the factory default reset. Then, afterthe reset and resolution of the original problem, you can restore the savedconfiguration to the switch. For both the save and restore processes, you canuse the console copy command. For more information on this command, seethe Management and Configuration Guide, which is on the DocumentationCD-ROM that came with your switch.You can restore the factory default configuration either on the switch itself,or through the switch console.To execute the factory default reset on the switch, perform these steps:1. Using pointed objects, simultaneously press both the Reset and Clearbuttons on the front of the switch.2. Continue to press the Clear button while releasing the Reset button.3. When the Test LED begins to blink, release the Clear button.The switch will then complete its self test and begin operating with itsconfiguration restored to the factory default settings.To restore the factory default configuration using the console, execute theerase startup-config command from the console command prompt.
