Figure C-1 Removing the Chassis Cover
Switch definitions and positions are as follows
Switch 7 - Clear NVRAM. Changing the position of this switch resets NVRAM on either the next power-up or the next operation of the front panel RESET button. All user-entered parameters, such as the IP address, device names, etc., are reset to the factory default settings. Once the 2E4X-27 resets, you can either use the factory default settings or re-enter your own parameters
