The first part describes how to mount a 365 Frame. Click here if you have a Plus+ Frame.
Mount the /dev/mount in your network rack. To find out how to mount it, follow this instruction.
Take your Frame and slide it into the rack unit and onto the threads of the /dev/mount, with the rack ears facing towards you.
Now, add the Patchcatch on both sides between the rail and the Frame (you can find an instruction here) and take the hex nuts of the /dev/mount and fasten them.
Mount the Mounting Rails in your network rack. Here you can find out how to mount the Mounting Rails.
There are hooks on both Mounting Rails, which should be facing inwards of the network rack. These hooks will hold your PATCHBOX/Frame.
To achieve that, carefully guide and slide in your PATCHBOX/Frame. The hook of the Mounting Rails needs to be hooked in the cutout provided for this purpose on the Frame.
The threads of the Mounting Rails should be put in the holes of the ears of the Frame. Now, add the Patchcatch on both sides between the rail and the Frame (you can find an instruction here) and take the hex nuts and fasten them.
