can you link the serial cable you ordered for the 6650? there's some listed on amazon that don't have the right connector (or are just a usb cable)My switch arrived but it did not come with a console/serial cable. Much hunting later and I found some on amazon and they will arrive on Monday. Then i'll flash the 6650 to the latest and go from there.
Overall: The sound is NOT that bad, but I don't have anything plugged into it just yet. No louder than my supermicro servers that I have running in my office and will be quiter once I close the doors to silence all the gear.
