Got it , really good to know. Any recommendation on the cable(s) I need to get into console of 7250?If you are using the exact same RJ45 serial cable you used on the 6450 on a port on the 7250 you will NOT get any serial output.
6450 has an RJ45 serial console connection.
7250 has a micro USB connection that is wired as a serial port. DO NOT plug in a standard "A to micro USB cable" betweeen the 7250 and a laptop or dekstop. If you do magic smoke may escape the 7250 and perhaps your computing device.
Any other way to get into the switch while I am waiting for the cable? it was 'reset' according to ebay seller
and for the record, I am trying to use the guide @fohdeesha provided below, connecting USB on my laptop through blue cable to management Ethernet port above the full size USB port. Should I be using something else instead? thank you
" Connect to the serial/console port using a program like Putty (9600 8N1), then connect the management ethernet port to your network (do NOT use any of the regular switch ports yet). The management port is the one above the full size USB port. "
