<![CDATA[SFP+ XG-1537 - no carrier]]>Hello,

I am using a brand new 1537 and the two SFP+ ports are not working.

I am using two of your cables (1meter) and trying to connect them with a Ubiquiti - EdgeSwitch Lite ES-24-Lite to connect them.

In the topic XG-1537 SFP+ ports I could read that it is probably due to FreeBSD and that it was fixed there and works again with the n#chsten version.

That is, if I now switch to the developer branch should the problem be fixed?

And the speed/duplex field in the gui will reflect that.

If it's a 1G port and cannot use 10G then using SFP+ fibre modules will usually allow it since those can be set to fixed 1G.

That sounds interesting, I almost think there is a possibility that it is only 1G.

Do you have a tip how I can set this?

If it's a 1G port and cannot use 10G then using SFP+ fibre modules will usually allow it since those can be set to fixed 1G.

Then I already have a solution and will have a look at it.

Thanks for the tip.

The port in pfSense can only be autoselect or fixed 10G and in connections like this autoselect usually fails to link at 1G. So if the switch port is configured at 1G fixed or can only be 1G it will probably fail to link.

I want to connect the Netgate to the switch.
Or am I misunderstanding you?

Does that switch have 10GbE ports?

Commonly it's not possible to set the link speed with DAC cables which means it will only link to other 10G ports.
