These switches are set at the factory and rarely need to be changed. Switch definitions and positions are as follows: • Switches 1 through 4 – For Enterasys Networks use only. • Switch 5 – If the boot up diagnostics have been disabled, changing the position of this switch will enable them. - Page 49 • Switch 6 – No function. • Switch 7 – Clear NVRAM. Changing the position of this switch resets NVRAM on the next power-up of the device. All user-entered parameters, such as the IP address, device names, etc., are reset to the factory default settings. Once the module resets, you can either use the factory default settings or reenter your own parameters.
