Ip conflict with the zyxel gs1200-5hp poe switch !?

Dear Sir / Madam,

I recently purchased a ZYXEL GS1200-5HP PoE switch as I want to send 4 Ruckus R310 unleashed access points from my Ubee EVW3200 modem / router from Ziggo.

I can not activate my Switch, whatever I try and wherever I search on the internet !?

Well, I suspect it's an IP conflict.

This is the only thing I can find: https://www.gadgetgear.nl/2016/11/review-zyxel-gs1200-8hp-managed-poe-netwerk-switch/

Installation
The installation is a completely different story. Buy one of these switches in one go and connect them immediately, you have a big problem. They are all hard at the IP address 192.168.1.3. You immediately get the necessary collisions on your network. If you already have another device on that IP address, it is also completely wrong. Then you first have to put that device on a different IP address or pop out of the network. And do you have a completely different IP range like us? Then you actually have to topple your entire network or connect one computer to the switch and adjust the configuration of the switch first. Remember, if you ever reset the switch again, it will return to this IP address. Where ZyXEL does its best in terms of interface to create a product that is as accessible as possible, they still get themselves back in the foot. Too bad, because this mess with hard IP addresses does not really have to be in 2016 anymore.

All very nice of course, but if they also put it all how this works, I can continue.

I hope that someone has experience with this and can help me further?

Mvr gr,
