WS-C3850-24T with C3850-NM-2-10G and non SFP+ receptacle

Dear colleagues,
Currently I'm designing to connect Dell R740(with 10 VM-s), equipped with Intel X520 DP 10Gb DA/SFP+(Dell PN: 540-BBBB) and two SFP+ modules - SFP+ SR Optic, 10GbE(Dell PN: 407-BBVK). My intention is to connect this server to  WS-C3850-24T with C3850-NM-2-10G + two SFP+ modules - Cisco SFP-10G-SR. Will it work for me? Hesitation raised, when I read in the specifications of C3850-NM-2-10G, that only the 4th receptacle support SFP+.
Thank you in advance for the comments!

Hi there,

The  C3850-NM-2-10G has four ports, the first two are 1G native and the ports 3 and 4 are 10G native so therefore support SFP+ 

 

cheers,

Seb.

Thank you very much, Seb! In that case I will purchase Cisco SFP-10G-SR for the 3 and 4 receptacle.

Depending on the distance to the server, you may want to consider SFP+ Twinax cables, they are considerably cheaper than buying optics and can reach up to 10 metres.

 

cheers
