Switch definitions and positions are as follows:

•Switches 1 through 4 – For Cabletron Systems use only.

•Switch 5 – COM Port Autobaud. The default (OFF) position enables Autobaud sensing on the COM port for Local Management sessions. Changing the switch to the ON position disables Autobaud sensing and sets the COM port to 9600 baud for Local Management sessions.

•Switch 6 – Forced BootP. Do NOT attempt a Forced BootP unless a BootP server has been configured for the 2M46-04R. The BootP server references the location of a station acting as a Trivial File Transfer Protocol (TFTP) server containing the 2M46-04R image file. When the position of Switch 6 is changed and the power is cycled to the 2M46-04R, the device requests the image file location from the BootP server and uses TFTP to download the image from the TFTP server. If one of these requirements is not met, the 2M46-04R will continue to request either the BootP server or the TFTP server until the RESET button on the 2M46-04R is pressed. Once the RESET button is pressed, the 2M46-04R will reset after one minute and load the image stored in FLASH memory.
