We’ve changed the radio, switch, cable to the roof, cable between switch and AC. Soft v6.49.13.

60Ghz link does not go down, radio on the other site has no problems. The only on is eth1 flapping on first one.

Soft upgrade should help? Maybe someone had similiar problem?

upgrade to latest stable FW, many changes from your version

3

I would do it if both sides has got these flaps. They not.

4

Where the other end of cable is connected? Have you checked that side?

5

Yup, I checked everything. Other end of cable is connected to switch without PoE. The switch was changed also, ports on switch too. Uptime doesn’t change

6

Bump, any ideas?

7

Could you try changing the power adapter and POE injector?
What does the log say on other side - in the same time?

Also check for errors on the interface (Rx FCS Error) + Cable test

Hello,
power adapter and poe injector was changed and it didn’t help. There’s also no log output on the other side.

After we replaced Cube there was no water inside, also it wasn’t rainy days ;D No errors on interface.
