Re: ALPHA ES 45
the env command in RMC will show you the warning / shutdown temperatures - these can be set as well but im not sure how you'd stand with hp contract wise if you did that and some of your circuits got fried.
why do you want to change these ?

Re: ALPHA ES 45
Here is the official temperature range for an operating AlphaServer ES45 box:
50├В┬░ to 95├В┬░ F (10├В┬░ to 35├В┬░ C)
This range from the official source for this stuff:
http://h18004.www1.hp.com/products/quickspecs/10994_div/10994_div.PDF
Also see the other recent discussions in:
http://forums13.itrc.hp.com/service/forums/questionanswer.do?threadId=1333707
IIRC, there are others.
Or check the technical specs and the service guide for the box, or the QuickSpecs or Systems and Options Catalog (SOC) for this stuff. This is the specified environmental conditions, and the best spot for these details.
Depending on the gear, look around these sites:
http://www.hp.com/go/productbulletin
http://docs.hp.com/
http://vt100.net/manx
For those folks here that work for HP in various capacities, there are almost certainly internal resources and libraries with details on the various servers and server environments.
Or as was mentioned, you can view the current thresholds with the RMC. Here's a write-up on the RMC for the AlphaServer ES40 series that will give you a feel for what is available and how this stuff works:
http://labs.hoffmanlabs.com/node/445
I do not tend to recommend use of the RMC value as the operating environment. Stay within the published environmental values for operating and storage, for humidity, and rate of change. If you're at shutdown, you're already outside the published temperature range.

Re: ALPHA ES 45
Thanks..
NO idea to change that temperature value.
I need to know,what it will be happened?.
Thank you

Re: ALPHA ES 45
Which leads to the question....
What are you up to here? Barring a military application or analogous life-critical operations and the "run regardless" option, I'm not aware of anyone that does this.
If you're running with a life-critical requirement, you will want to work directly with HP here.
I'm guessing you're probably not looking at water-cooling or other aggressive and retrofitted system and processor cooling techniques. (A set of water-cooling blocks on the processors of an AlphaServer ES45 would be an interesting and entertaining technical challenge.) That or the more typical environmental cooling are on your paths forward here, if you proceed.
These RMC temperature thresholds you're asking about are intended to protect the Alpha microprocessor from irreversible and permanent physical damage. These last-chance settings are intended to avoid the destruction of the CPUs within your AlphaServer ES45 box.
If you need to reset these thermal limit values to more aggressive and hotter values; to temperatures beyond what the RMC would or should allow, then you'll likely have to load new microcode into the box. And that presumes you work at HP or otherwise have access to the box. I'd be surprised if the RMC allowed values outside the specifications. Which is why you'll want to work with HP, particulalarly if this is a life-critical application.
If this is not life-critical application, then just destroy the Alpha CPUs with whatever physical or chemical or thermal means you might wish. That'll be easier to accomplish, and will have effectively produce the same results as what you're asking for here.
I'd suggest checking with your manager. Ask for some guidance on this task you have been assigned. Water-cooling? New RMC firmware? Life-critical?

Re: ALPHA ES 45
"I have no intention of changing" (NO idea to change) that "shutdown" temperature value.
I need to know, "at what temperature" (what) it will (be) happen (ed)?.
I think that's what he meant.
Cheers,

Re: ALPHA ES 45
I have studied the above link and coudn't identify the shutdown temperature value.
Kindly help me how can i view the thresold value of ES 45 server.
Thank you

Re: ALPHA ES 45
Smart answer: go read the platform manuals, and go look at the specific RMC setting on the specific box. I'd not assume the RMC threshold value is the same from box to box.
Best answer: don't let the room get outside the specified temperature range. Keep the room and the box below 35C.
Or contact your own manager, or a corporate or consultant platform technical specialist, and reference this thread and the particular problem or question you are trying to address here, and work out the required details that way.
