SIMM UpgradeB-6 Optional Installations and Mode Switch Bank SettingsDO NOT attempt a Forced BootP unless a BootP server has been configured for the2E253-49R. The BootP server references the location of a station acting as a Trivial FileTransfer Protocol (TFTP) server containing the 2E253-49R image file.When the position of Switch 6 is changed and the power is cycled to the 2E253-49R,the device requests the image file location from the BootP server and uses TFTP todownload the image from the TFTP server. If one of these requirements is not met, the2E253-49R continues to request either the BootP server or the TFTP server until theRESET button on the 2E253-49R is pressed. Once the RESET button is pressed, the2E253-49R resets after one minute and loads the image stored in FLASH memory.• Switch 7 – Clear NVRAM. Changing the position of this switch resets NVRAM on thenext power-up of the device. All user-entered parameters, such as the IP address, devicenames, etc., are reset to the factory default settings.

Changing the position of this switchclears user-entered passwords stored in NVRAM, and restores the factory defaultpasswords on the next power-up of the device.
