This week I am configuring (2) 6504's with 4 WiSMs for a brand new installation. We are deploying Cisco's new 1142 802.11n access points in a location grade deisgn. As part of the deployment and configuration I needed to restore one of the WiSMs back to factory default. I wanted to share with you the procedure and CLI commands.
1. First, you need to reset the controller. Enter reset system at the command prompt.
2. At the prompt that asks whether you need to save changes to the configuration, enter Y or N, doesn’t matter what you select. The controller will then reboot.
3. When you are prompted for a username, enter recover-config to restore the factory default configuration.
Press enter and the controller will reset back to factory default.
