[AusNOG] Cooling Pads for Juniper SRX?

[Brad Peczka]

Rather than looking at the technology, why not look at the enclosure?

Sunshades are a viable option for passive cooling on outdoor enclosures - depending on the vendor, you can get them integrated at the factory (i.e. http://www.brenclosures.com.au/sp-sunshades.htm) or ordered as a retrofit kit (http://www.brenclosures.com.au/sp-retrofit.htm), and they'll provide much better cooling than a pad full of fans that will just end up pushing hot air around.

Regards,
-Brad.

Hi all,

I have an issue with some Juniper SRX100's overheating.  I've seen them get hot before, especially placed on something similar (i.e. another SRX100)... and given warnings of overheating, but never shut down.... but this situation is different.

These SRX100's are shutting down as they are reaching a core temperature of 70c as they are located in racks that are outside in the sun and on particularly hot days - around 32c-36c they overheat and turn themselves off.

Some might say this is understandable... and I sort of agree.  Although their operating system says they are good to 40c, that doesn't really seem to be the case.  The SRX110's are a little more tolerant given they are bigger units - but have the same operating environmentals (along with the EX2200-C).  But at the moment I have the SRX100's and would prefer not to swap them out as it will cost significantly.

Then one of my staff had (what I think) a good idea today... to use cooling pads... maybe like the ones you use for laptops or something.

So I am wondering if anyone has been some solid - not $20 junk or such.. but something that runs off mains, and works well 24x7x365 - maybe even something that only kicks in once a certain temperature has been reached.

I thought if anywhere, a couple of these mailing lists might have had some experience with these kinds of things - especially for those who have built regional pops and have had to cool some equipment.

Thanks all!
