temperatue and humidity N class
I just read some site prep doc, and the ranges are very wide. I've always kept temps kind of on the low side, 65F, and see in the doc. that is too low, (68F recommended).
My question:
What temps and humid. numbers are in your computer rooms?

Re: temperatue and humidity N class
maybe it can be useful:
Temperature:
- Up to 29 C works the N- or L-class 'normal'.
- At 30C generates the power monitor an interrupt for the envd (over temp low).
- At 35C performs the power monitor the next interrupt (over temp mid).
Of course temperature above is in Celsius degrees.
Also: man envd.
Best regards,
Ettore

However, my basic rule of thumb is "If I'm happy, the 'puters are happy."

Re: temperatue and humidity N class
68 degrees 40/45% works for me.
Had an AC failure last year, took me 10 mins to get there and in that time temp had hit 45 degrees celcius. All the N Classes had said " you want me to work in this temperature - I Dont Think so" and had shut down.
Failure had turned out to be mains failure and generator had failed to cut in.
So dont forget your testing should include everything.

Re: temperatue and humidity N class
Heat is the ENEMY of reliability for computers! Only the newest HP computers will shutdown to prevent meltdown, but your poor disks and tape drives will be destroyed if the temperature rises above 115-125 deg F (46-51 deg C). Be sure that you have SEVERAL controls to limit temperature including a simple temperture sensitive circuit breaker to disconnect all power in the room when the temp goes above 115 deg (46 deg C).
