Group: I have a system that will be going through NEBS Level 3 and equivalent ETSI certifications. Our mechanical group hasbeen working with a design requirement that they indicate is related to these certifications (but can't provide a specific reference) that limits the depth of any cable routing channels, etc. to two inches beyond the front panels. This is specifically challenging because most of the front panel connections are coax, which have separate minimum bending radius requirements.
I'm not aware of anything in GR-63 or GR-1089 and don't believe there was anything in GR-78 about this, but since there always seems to be just _one more_ GR that I get aquainted with - just when my comfort level was getting good - I was hoping that someone on the list might acquaint me with where in the Telcordia requirements (or ETSI, or elsewhere) I might find said reference. I'm under the impression I've seen and worked with equipment that abjectly violates it if it exists. I'm assuming that's mainly a point to be negotiated with the appropriate end-user.... If this is a common urban legend that you can help me debunk, then I would appreciate that, as well. Regards, Michael Garretson Compliance Engineering Manager RadiSys Corporation +1 503 615-1227
