The ONT is probably OK. Looks like the hybrid cable is going all the way in to the splice tray on the back so is taking most of the strain off - although strain relief is just a zip tie sooooo..

 

What I would be worried about though, is to get that ONT off, they would have had to take it off the back mount/splice tray. If you aren't sure what to expect, very easy to break a splice. When the ONT is powered back on, just make sure you get a green optical light. if it's red, call your provider right away to get a fault logged. And then be prepared to get a bill from Chorus for fixing it.

 

Thanks for the tips, and info about the back mount. It will be the installer who would need to sort out fixing it / billing etc if it isn't working after they have completed their work. The internet connection was working fine prior to them removing it, as I was using the internet over wifi on it, so they couldn't blame it on a chorus installation problem.
