Wall mounting cabinet?

Question

Iron

There is a wall cabinet Zpas sj-106 (it seems that the name was correctly determined). At the link above there is an item "Changed rear panel mounting".
Interested in the question: does this apply to all cabinets of this series?
I'll outline the situation. An optical fiber is brought into such a cabinet and an optical cross is mounted. It is necessary to pull out the cross without disassembling it. If the back wall is removed, then I can saw through a piece of the upper back edge and pull the cross through the back wall. But if it is non-removable, then you will have to disassemble the cross, which you absolutely do not want to do. Maybe someone came across this particular model or can feel them live.

Answer 1

Judging by the drawings and past experience with racks, the back wall is removed (this can be seen below in your link in the photos without a back wall at all), but I'm not sure that you can remove it without removing the cabinet from the wall.
Good luck!

Answer 2

Look carefully at the photo:
The bottom plate and the top plate - near the ears for which the cabinet is hung on the wall, you can see the bolts that fasten the back wall, check for the presence of the same bolts in your
cabinet the back wall can only be outside, i.e. the cabinet will have to be removed from the wall first.
True, there is also a photo “The rear panel mount has been changed” and it is small, you can’t really make out anything on it what exactly was changed.
