Mikrotik SXT LTE powering issue

I received new mikrotik SXT LTE (r11e-lte) today, but have powering issue. I connected PoE injector to the power and connected to the router ETH1 port via ethernet cable, but has no reaction. I watched video instructions and I am doing everything the same way, but it’s not powering on.

Is the device damaged or am I doing anything wrong?

With the included Mikrotik POE injector, with the included Mikrotik power adapter, via a ethernet cable of supported length?
