Plenum-rated transceivers could be used in the plenum, the environmental air space above drop ceilings (and other places). Plenum-rated transceiver and coax cable is common. I note that the standard DEC transceiver says on its label very specifically that it is NOT plenum rated, as do the BICC and 3COM transceivers we use. The Cabletron transceiver literature says "conforms to UL 910 and NEC 725-2(b) requirements for installation in air-handling spaces". A quick phone call to our rep had him reading this verbatum over the phone, which wasn't much help. Other phone calls have yielded similar results. A call to our University electrician, who is supposed to know at least the codes, was not of much use. So here I am wasting everyone's bandwidth. Does anyone have specific recommendations, including vendor name and part number? If anyone else is interested, I'll investigate it from there and summerize results.
