When you reboot it does it do the same thing? (turn off and back on)<br>Were you in the console or telneted in? You can try a break sequence during the reboot and try getting to the ROMMON prompt. If you don't get any information at all and you are on the console port contact the vendor and have it replaced. <br>Is it set to boot from flash, tftp server, or ram? If is was set to boot from tftp and their is no server possibly. It is hard to say. Let me know what happens. <br><br>Rob
