CCR1009-8G-1S-1S+ SPF+ port not working

Hardware MikroTik hardware general

Hi,

I have a CCR1009-8G-1S-1S+ and a CRS125-24G-1S-RM where I wanted to use the CCRs SFP+ port to connect to the CRS SFP port using the MikroTik S-85DLC05D modules.

According to the specs the SFP+ on the CCR1009 also support the 1.25G modules and the module is recognized by the system but the link doesn’t get established between the devices.

The CCR1009 shows link-ok, but the CRS125 shows no-link so I guess on the SFP+ port the RX works but the TX doesn’t.

I have upgraded RouterOS to the last versions v6.34.2 and also the firmware to the latest 3.27.

Anyone have any idea where could be the problem?

Thanks!

Change the Rx / Tx cables on the fibre part.

Remember: Right is ALWAYS Rx, LEFT is TX. Very easy to remember: Right is Rx (R=R).
