hello i tried connecting a cisco nexus 3k to a dell n3048 using the 1gig combo sfp port but received a notice that the transceiver was not dell qualified.
i was using a cisco 10 gig twinax cable
why does the cable not work? what are my options for connection? i like twinax because its nice and easy. does dell have its own twinax cable that would work?
The SFP+ ports on the switch support passive direct attach cables. Here is a link to one of the Dell cables.
Sometimes firmware can play a role in interoperability. You may want to check to see if the switch is up to date.
i have 2 cables
CABLE1: Lorom e-maxx high speed (UL) 2 pair 24AWG shielded CM 75C (UL) E141823-6 161227
CABLE2; MADISON CABLE (A11) (UL) TYPE CL2 75 24 AWG CSA AWM II A/B 80 30V FT4 TURBOTWIN 10G RoHS COMPLAINT 0317
ran the command. no change . also tried the 10 gig port and it still shows up as being not dell qualified.
this makes me think that its mandatory to use a dell twinax cable .
