connecting dell n3048 to nexus 3k

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.

this is the cisco twinax part # that i am using . should it be compatible?

the dell switch is already running 6.3.2.4 code. 

I show that cable to work, but it needs to be rev A02. Do you know what revision this cable is?

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

SFP-H10GB-CU5M COPQAA5JAB

That Cisco cable should work as long as it says v02 or higher on the transceiver portion. If it is v01, it may not work.

Can you please try running the command # service unsupported-transceiver, and see if the behavior changes.

Thanks

ok well it says V03. 

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 .
