In a hazardous environment the Cisco AIR-CAP1552H AP is often used. Sure, it's almost end of Sale, but my question is around the omnidirectional antennas that this model of AP supports.
The AIR-ANT2547V series has three flavours (see datasheet)
What is the implication of NOT installing the antenna with the -HZ suffix? Does that mean the other two antennas should NOT be used in a hazardous environment? Why would Cisco state that you can install a non haz antenna on an AP that is purpose built for hazardous environments? And if the V-N and VG-N antennas are indeed safe to use in hazardous environments, then what the heck is the N-HZ antenna for? Cisco table below says "hazardous". If someone has authoritative information then please respond. I am as good as guessing as anyone - that doesn't help me.
My guess is that the AP supports all those antennas and the -HZ antenna is used when the APs is actually installed in the hazardous area.
Might be best to check with your Cisco SE to see clarification from Cisco directly
thanks for that. I suspected the same. Customer definitely has these APs in hazardous environments (everything has to be intrinsically safe - gas, danger of explosions etc.) - and therefore I am trying to get confirmation.
I will check with local SE.
Hello... use this b_iw6300_hig.pdf to get the best information about those APs. But he difference is the -HZ has a intermediated frequency band between 2.4 and 5 Ghz and is certified to UL 50E standard for Electrical Equipment Enclosures (because UL does not have a standard that is harmonized with the IEC)
AIR-ANT2450V-N-HZ = 2.4-2.483 5.25-5.85GHz 4/7 dBi Omni by Laird Technologies (UL 50E, type 4 or 4X.)
