Arris Surfboard S33 S34 Rack Mount Adapter

A rack mount bracket that allows you to mount your cable modem into your network rack no matter which width of rack you have. 

The original base was pulled from here:

My contribution is the creation of the 40mm fan cooling end cap. 

- The solution was built and tested with 2x 40mm 5V fans.
  (Note, tolerances are tight with the fans but I left the modifiers in place, allows you to increase the space if needed.)
- There is a channel to re-direct the fan power cables out the back. Please install the furthest fan first. 
 

2 different end caps

 - Bolt / Nut - have recesses to allow you to use a nut and bolt for securing the fans.

 - Threaded Inserts - can install 4-8 threaded inserts into the body to secure the fans. 
 

Parts:

To attach endcap to body
4x M3 Threaded Inserts (L5 would be most ideal but any length is acceptable)
4x M3-.8x20mm bolts (10mm length if not using the cooling endcap).

To secure fans to endcaps
 *You don't need all 4 per fan, you can use 2 per fan. 
4x-8x M3xD5xL3 Threaded Inserts - (L3 is the ideal depth). 
4x-8x M3-.8x10mm bolts - (10mm is the ideal length. Shorter or longer will not reach or over extend.)
2x 40mm Fans (40x40x10mm) - 12v fans will move more air but will also produce more noise. 5v and 12v fan options are available online. Remember to also acquire a splitter cable and an appropriate power supply to operate the fans.

Modifications:

The end caps have all the modifiers available for you to make adjustments. You can re-size the endcap easily in case you want to use thicker 20mm fans (via BambuLabs Studio).
