All active port LEDs flashing on CRS106

Fri Aug 13, 2021 9:51 am

We have another switch we want to connect to our crs106-1c-5s. When we connect it with SFP+ modules running at 1310 and a 1m OS2 cable it works properly.

When we run it through a fibre patch panel and all of the cables are OS2 all of the existing active ports (2 & 3, we're adding another device on 4) on the CRS106 flash at the same time when we connect the SFP port. It then does nothing, port 4 shows the SFP module as connected but doesn’t show as running.

The cables and fibre link work properly connecting other network devices and the devices work properly when they are directly linked using a patch cable.

What would cause all of the ports to flash at the same time?
