Switch definitions and positions are as follows
Switches 1 through 4 - For Cabletron Systems use only
Switch 7 - Clear NVRAM. Changing the position of this switch resets NVRAM on the next power-up. All user-entered parameters, such as the IP address, device names, etc., are reset to the factory default settings. Once the device resets, you can either use the factory default settings or reenter your own parameters
