If you are considering selling beyond the North America, I would advise you procure a copy of ETS 300 119-4: Equipment engineering (EE) European telecommunication standard for equipment practice Part 4: Engineering requirements for subracks in miscellaneous racks and cabinets It indicates a maximum depth behind the flanges of 240mm with 40mm in front (including connectors etc) for 300mm deep racks. For 600mm deep racks the dimensions are 470mm behind and 75mm in front of the flanges. ETSI also specify two width options.

You can't have equipment going back the full depth of a rack. Otherwise, cables couldn't be installed and air circulation within the rack would be severely limited. Someone somewhere within Bell said, "then let it be 12 inches deep". Also, don't take the width as absolute, either. There's also a 23 inch width rack out there. Ignoring this fact can lead to tainted marketing careers, lag on sales, bull headed high level meetings to find any scapegoat, public flogging, and of course dissatisfied customers. > From: Joe Finlayson <[email protected]> > To: [email protected] > Subject: NEBS chassis maximum depth requirements > Date: Wednesday, September 03, 1997 3:07 PM > > Hello TREG, > > I am in the process of spec'ing out a new chassis product and it is > necessary that it meet the NEBS requirements.
