Who is the authority on temperature and humidity guidelines on CAMPUS. If i have a telecom closet with no windows and built in the middle of a floor so you can walk around it completely; its constructed of plywood and covered with drywall. What should the operating temperatures be consistently. I have found 98 degrees F. on Friday and today I found 87. From my experiences this kind of temperature is bad for long term exposure on the mission critical gear in there. Any suggestions would be appreciated.
