Rack mount for the netgate 4200

This is a simple rack mount that centers the firewall in a standard 19 inch rack, leveraging the pre-existing mounting holes designed for the wall mount kit.

Rack support

While the bracket is 1U high, the actual height of the firewall is greater than 1U. As such, it's been designed so the rack unit is flush with the bottom of the firewall (small feet have to be removed first with a torx T10 bit) - and the extra height spills into the above rack unit. The firewall is offset backwards to allow room so that a blanking panel can still be used for the slot above.

As per images from my 'test rack' (which is actually just an old commandeered rack utilised as my 3d printer enclosure), you can fit any standard rack mount device under the firewall as it's flush to standard rack units. Above is more restrictive as the firewall domes at least 20mm above 1U height. I've tried a connectix modular patch panel and blanking plate, both have enough clearance from the depth offset given by the mount.

I may update at some point with better provisions for managing the power cable, and maybe a power supply mount too.

As the sides of the 4200 are not perfectly straight (it tapers in slightly) - it's best to slightly bend the bracket then sinch down with cage nuts to keep the whole thing level.

Print settings

I printed using an ender 3v2 and black PLA

• 0.3mm layer height
• 100% infill
• 60mm/s print speed
• no support

The model was oriented such that the front of the bracket was on the build plate, as this is the only visible part once installed. At least with my printer, the diagonal structure for ventilation printed fine despite being quite thin with no support.
