[AusNOG] Cooling Pads for Juniper SRX?

[Peter Tiggerdine]

Working in mining where we have lots of the Cisco IEC 2000 in cabinets that
have no cooling or ventilation we normally have cover over the cabinet
(Tin, Solar Panels etc..) to reduce the temp somewhat. There devices do get
to 60+ degrees and train on without to many problems.
