SG350X DAC Not Showing Up in UI

[Snows]

Could not find any info about DACs compatibility with the Sg350x28P line. From my understand they are just copper sfp+ passive or active. I really hope I did not buy a switch witch will not work for me. I have tried 2 different cables no difference in out come. Hope fully some with more Knowledge on this subject could school me Thanks.

Hello, 

Happy New 2019 Year!

DAC cables: 

SFP-H10GB-CU1M  

SFP-H10GB-CU3M

SFP-H10GB-CU5M

Upgrade the firmware to latest :

https://software.cisco.com/download/home/286288281/type/282463181/release/2.4.5.71?i=!pp

The command to view the sfp:

switchxxxxxx# show inventory

Hope it helps

Cheers, 

Mike

Will the SFP-H10GB-CU2M Not Work ? It does show up in Optical Module Status As a CU2M What is the difference ?

 Also I am Trying to Connect this to a Mellanox ConnectX-2 will these cable also work for that ?

Hello,

Yes, it should work if the switch sees it - these numbers mean the length of the cable in meters.

Cisco SFP-H10GB-CU1M	-	Twinax cable, passive, 30AWG cable assembly	-	-	1m
Cisco SFP-H10GB-CU1-5M	-	Twinax cable, passive, 30AWG cable assembly	-	-	1.5m
Cisco SFP-H10GB-CU2M	-	Twinax cable, passive, 30AWG cable assembly	-	-	2m
Cisco SFP-H10GB-CU2-5M	-	Twinax cable, passive, 30AWG cable assembly	-	-	2.5m
Cisco SFP-H10GB-CU3M	-	Twinax cable, passive, 30AWG cable assembly	-	-	3m
Cisco SFP-H10GB-CU4M	-	Twinax cable, passive, 24AWG or 26AWG cable assembly	-	-	4m
Cisco SFP-H10GB-CU5M	-	Twinax cable, passive, 24AWG or 26AWG cable assembly	-	-	5m

As for the Mellanox - generally it should work as it is passive and not so long, but you can ask them, or consult with datasheet just in case.

Cheers,

Mike
