BTU Ratings

I need to find out what the btu rating is for my family of HP servers before my A/C goes belly up.
I have LT6000r, LXR8000, LP2000r, LH3, LH3r, LPr, LXpro NetServers and A500, B132L, C360, N4000, L2000 and V2500 HP-UX.
Does someone out there have some or all of these rating?

TIA.

Re: BTU Ratings

The basic formula for calculating the BTU rating of any equipment
is as follows:

BTU = (Watts X .95) X 3.414


As per document

A1509761


So just look at the power supply rating and get your calculator out.

Re: BTU Ratings

If it where only just that easy! Most of the servers do not have the wattage listed in an accessible location and the documentation/Web sites do not list wattage on most servers!!

Re: BTU Ratings

Mark, check with your facilities department. The electricians should have a clamp-on amp meter. Just clamp this over the power cords for a second, write down the reading and multiply by volts to get Watts. If any box draws less than 1 amp (the usual lower limit for these meters) assume 1 amp.

Re: BTU Ratings

For Netservers you can use tool called Rack Assistent to calculate BTU ratings: simply put the servers in the rack and rack assistent will calculate BTU (and many other things like power consuption, weight, etc.). This tool is public available: go to netserver web site (netserver.hp.com) select configuration tools, rack assistent, download it and use it.

Re: BTU Ratings

Thanks Paul for you help but I have been informed that if the machine is not at full power then the reading will be inaccurate as I need to calculate maximum heat dissipation.

N4000 10,230 (8050 typical)
