Using DIP Switch 6

The purpose of DIP switch 6 is to force a Flash download from a BootP server through the EM-EPIM. The first step in this process is to configure the BootP server. Configurations of BootP servers can differ from platform to platform and from one operating system to another. Read the user’s manual on BootP and TFTP serving for the correct files to edit and the correct files to execute for the server. After configuration of the BootP server the module can then have the switch state changed on dip switch 6 to initiate BootP and TFTP requests.

When the state of dip switch 6 is changed, the module begins requesting a BootP server in an attempt to receive a Flash image download. The modules boot PROM initiates a BootP sequence. During this sequence, the module requests an IP address and a filename from the BootP server. The module then requests a TFTP of the file and receives the download of the image. The module will not function until the Flash image is downloaded from the BootP and TFTP server.

If a BootP and TFTP are not intended at this time, this process may be stopped by resetting the module. Resetting is done by pushing the reset button on the module, power cycling the chassis, or removing the module from the chassis and re-inserting. (See section titled The Reset Switch on page 2-8.) After resetting, the module again looks for a BootP server, but will time-out after about four minutes. After the time-out, the module boots from Flash memory. The next time the power is cycled, the module will boot from Flash memory and not request the BootP server.
