Martin,

If there is an online link to the bellcore standard could you please
post it?  Thank you.

Datacenter temperature is open for speculation :) but I believe that the
Bellcore standard is < 71F. I don't have the docs in front of me.

Now, I'm not saying that's what you should use, but I typically take the
Bellcore recommendation, and adapt it to my needs, wants, and $$$.

Remember, every degree is going to cost you power. Also, did you get
humidifiers with your units? That's where people will complain i.e. if
it's too wet, or too dry.
