Question about Zyxel AX7501

Hello everyone The question for me is whether the housing of the router fits into our electrical cabinet. We have been using the Swisscom router there successfully for the last 7 years. I can see the dimensions of this Zyxel AX7501 router on this page: Length: 18.7 cm (does it still need space for the cables?) Width: 25 cm (or does it still need space for the cables?) Height: 3.3 cm I would now like to know on which side the connections for the cables are located? My slot is 21 cm wide. So if the cables are plugged in on the 18.7 cm side, this will of course be correspondingly longer (approx. + 5 cm) = 23.7 cm And with a width of 25 cm, the housing will no longer fit into the slot. However, if the cables are plugged in on the longer side (with 25 cm), this requires approx. + 5 cm more space, i.e. approx. 30 cm. And the narrowest side with 18.7 cm would then remain and the device would still have a width of 18.7 cm after cable installation and would have plenty of space. Unfortunately, the Zyxel website does not show which dimension is on which edge of the housing. Can someone who has such a device tell me this here? Would be super helpful! Thank you very much!
