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.</p></div><div><p class="MsoNormal"> </p></div><div><p class="MsoNormal">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.</p></div><div><p class="MsoNormal"> </p></div><div><p class="MsoNormal">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.</p></div><div><p class="MsoNormal"> </p></div><div><p class="MsoNormal">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.</p></div><div><p class="MsoNormal"> </p></div><div><p class="MsoNormal">Thanks all!<br clear="all"></p><div><div><div><div><p class="MsoNormal"><br>...Skeeve</p></div><div><p class="MsoNormal"> </p></div><div><div><p class="MsoNormal"><b><span style="font-size:10.0pt;font-family:"Calibri",sans-serif">Skeeve Stevens - </span></b><span style="font-size:10.0pt;font-family:"Calibri",sans-serif">eintellego Networks Pty Ltd</span></p></div><div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Calibri",sans-serif"><a href="mailto:skeeve@eintellegonetworks.com" target="_blank">skeeve@eintellegonetworks.com</a> ; <a href="http://www.eintellegonetworks.com/" target="_blank">www.eintellegonetworks.com</a></span></p><p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:10.0pt;font-family:"Calibri",sans-serif">Phone: 1300 239 038; Cell +61 (0)414 753 383 ; skype://skeeve</span></p><p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:10.0pt;font-family:"Calibri",sans-serif"><a href="http://facebook.com/eintellegonetworks" target="_blank">facebook.com/eintellegonetworks</a> ; <a href="http://linkedin.com/in/skeeve" target="_blank">linkedin.com/in/skeeve</a> </span></p><p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:10.0pt;font-family:"Calibri",sans-serif"><a href="http://twitter.com/theispguy" target="_blank">twitter.com/theispguy</a><span style="color:black"> ; blog: </span><a href="http://www.theispguy.com/" target="_blank">www.theispguy.com</a></span></p><p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:10.0pt;font-family:"Calibri",sans-serif;border:solid windowtext 1.0pt;padding:0cm"><img border="0" width="100" height="100" id="_x0000_i1025" src="cid:~WRD000.jpg" alt="Image removed by sender."></span><span style="font-size:10.0pt;font-family:"Calibri",sans-serif"></span></p><p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:10.0pt;font-family:"Calibri",sans-serif;color:#7f007f">The Experts Who The Experts Call</span></p></div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Calibri",sans-serif;color:#002060">Juniper - Cisco - Cloud - Consulting - IPv4 Brokering</span><span style="font-size:10.5pt;font-family:"Calibri",sans-serif;color:#7f007f"></span></p></div></div></div></div></div></div></div></div></div></body></html>
