sophos UTM9 SG125 & CISCO SG200-26 26-Port Gigabit Smart Switch 1gB connection

Hello Support, 

We have a Sophos SG125 with on ETH1 configured our External (WAN). It is connected to our CISCO SG200-26 26-Port Gigabit Smart Switch but unfortunately, I can't get it configured to a 1GB speed connection.

When changing it to 1gb it breaks.
