gs724tv3 amber light after firmware update
i purchased this switch second hand. worked great. flashed with latest firmware now i have an amber light and that's it. I tried to fix by following details in this link: https://community.netgear...

So i figured it out. i already had a usb to rs232 converter but what i didn't know is that i needed an rs232 TTL with the "TTL" being the important part. Who knew? So once i got the correct adapter i hooked up to the switch and followed the instructions at http://www.dutn.nl/repairs/reparaties_gs724t.html just make sure you flash the original firmware off of netgears site and then upgrade from there. also make sure you make what ever image you upload to the switch "active" which is what i did not do before upgrading the switch in the first place.

i tried to follow the directions from that site already. all i get from the console is gibberish. i'm wondering what i'm doing wrong. i connect up the wires and have used hyperterminal and putty. i get gibberish comming across the wire. i've tried different baud rates without success. do i need to enable some sort of decoding on the terminal emulator? also i know i've got the wires hooked correctly because my key presses cause activity in the terminal window even though i can't make anything out.
thanks
