Hi
sergeant72,
I don't know if this helps, but I pulled the following from the manual that Joe posted:
Each SFP+ and QSFP port accepts direct attach passive and active copper cables. The SFP+ ports accept class I 10GBASE-SR and 10GBASE-LR optical transceivers up to 1W per port and the QSFP ports accept Class 1, 2 and 3 modules up to 2.5W per port.
Could your non-working cables be of a different class and/or watt rating than above?
The non-working one was received a while back from China through ebay, no markings on it.
The fiber one has the following "850nm LASER PROD, 21CFR(J) CLASS 1M"
I guess my expectations were that if those cables were working in direct connect between cards, they should be working with the switch.
Anyway, continue poking in the CLI, here is more info regarding the transceivers:
