Hello!
I currently am attempting to connect two CISCO 2960-S (WS-C2960S-48TS-L) Switches together via one of the four SPF ports on either switch. I currently only have the cable:
Brocade 10G Active 3m FCoE
San Jose CA
58-1000027-01
Made in China
SN: CBX114490003423
This cable (per the 10G) I presume is designed to be a 10GB SPF cable. It fits into the slot, however no lights ignite with a feiry orange or green passion on the switch. Is there a compatability issue with the switches and cable? I was under the naive assumption SPF is similar to RJ-45 where you can use higher rated cables for slower slots. Thank you in advance for any clarification!

Hi that's a compatibility issue , Brocade 10GBs can only work as fixed 10GB they cannot downgrade automatically depending on connecting devices thats why your getting nothing at all not even a light , the switch would not be able to recognize a 10GB if it only supports 1GB
