Better use the connection while you can to bring up Noah's designs. BTW: Thanks for the post, Patrick!

It matters, as the nature of your environment informs you about the gear you need to use. Do you have broad temperature swings? Thermal expansion can cause cracking around connector housings in some levels of gear. Ice storms? Nothing exploits a crack like freezing water. Operate near the desert? Dust protection matters. Near the coast? Salt is highly corrosive. Are you complaining about water getting into your boxes? If you don't know the IP rating, you really can't complain becuase you may be using the gear beyond its specs. As in the law, ignorance is no defense, so in the interest of dispelling ignorance, here's a quick tutorial on the "IP rating." First, it's not sequential. I mean, the two digits have no relation to each other. In that sense it is NOT a number: IP55 does not mean IP "fifty-five," but rather is more appropriately thought of as IP "five five." Come again?!? Well, the first number refers to protection level from particulate matter -- solids -- like dust and sand. The second number deals with protection from liquid incursion. (There can be a third number, usually left out, that deals with mechanical tolerance.) In any event, here's the key to crack the code: <image002.png> <image005.png> Know the rating of your equipment, at both ends. Environmental truck rolls are almost 100% avoidable. Environmental failure at the base station impacts the whole sector. Failures at the CPE level can cause repeated truck rolls and is a time sink trying to identify root cause before the truck rolls. Outdoor devices with a first digit of 5 or less, will take in dust. Similarly, anything with a second number of 6 or below will take on water because it was not designed not to. These are consequential specifications. You'd better believe your telco or cable competition has minimum environmental requirements as a rule. Are you any less serious a player in your market? Control those variables within your control. Regards, Patrick Leary National Sales Director | Telrad Networks Ltd .
