Bought this cable for console with my Brocade 10gb switches and didn't go, finally found cable spec for console Brocade cables and its 2<->2 3<->3 7<->7 8<->8 others are reserved. I had to shorten and patch the cable. No vendor fault, he says ZERO, and pretty sure Cisco etc is keeping an eye on it, but Brocade is doing its thing :-( 2 hours later the switch is up.
