Shutdown temp

[Christopher A. Payton]

I'm looking for the safe operating temp of the HP D class 9000 D370. Or the method of finding it out. None of my documentation shows it. Thanks

According to

http://docs.hp.com/hpux/pdf/Z7634-96002.pdf

the operating temperature range for a D class is Operating: 5-40 C 41-104 F
Non-Operating: -40 to 45C -40 to 113F
Short-term Operating: -5 to 50C 23 to 122F

While the max limits are 41-104 deg F, I would not be confident in hardware operating for long periods at either extreme. The best rule of thumb is that if you are not comfortable with the temperature (ie, can you work in the temperature for 8 hours), then it is too cold/hot. High temperatures accelerate hardware failure and the cost to fix the temperature is always much less than the cost to repair/replace all the equipment that might fail running at 104 deg F for weeks and weeks.

I start getting nervous when the computer room approaches 80-85 & I start shutting down systems, getting mad & looking for maint people if it passes 90. Note that some systems, the V-class for ex will take them selves down if the air intake temp reaches a certain point.

Rgds,

Christopher,

I use a rule of thumb that you should not operate a computer in an area that is uncomfortable for a human operator to co-exist in. You will always want to find the weakest link in your hardware equipment and choose its specifications as the minimums and maximums.

For example, disk drives and tape devices use binder that can break down and allow the medium surface of the backup material to get "mushy" at 80 to 85 degrees farenheit. excessive data errors can occur, and in some cases, even soft, disk crashes where the heads scrape off the media coating and it sticks to the heads.

Most computers like it colder, rather than warmer, and try to keep the humidity between 40 to 60 percent.

Humidity that is too low can cause static discharging and humidity that is too high can cause condensation to form.

Hope that helps.

Hi Chris

I would be personally looking for the person who is responsible for the maintenence
of the room in which your systems are located.

Let the grown ups know the score and take responsibilty.


Of course the techincal details provided are great but do you have any control over the tempreature.

good luck
John.
