RE: [smartBridges] POE, voltage range

[Joe Kelley]

I agree about the power shot   Computers and satellite systems as well have been making switching power supplies for years ie the product only uses the power it needs   While we are on the subject of changing the product   I personally do not like the new waterproof enclosure  we are sealing where the wires go in from the radio We think that water will eventually penetrate if allowed to catch in that mini basin   The radios can only be positioned in an upright position, Why can’t the jack be inside the radio like Motorola And Trango. Just tighten the connector on your cat 5 cable     -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Jack Berridge Sent: Thursday, June 12, 2003 9:50 AM To: [EMAIL PROTECTED] Subject: RE: [smartBridges] POE, voltage range   Sounds interesting....and scary.  I'm not an EE but when you start talking about an "intelligent powershot" that is capable of making decision based on "sensing the cabling length" it scares me.  This scares me because "intelligent devices" tend to die (fail) more often than a good old dumb device that's only purpose is to provide a specific (designed/engineered) amount of power.  To me, I see an intelligent device as another point of failure just waiting to happen.  Whereas, if we had a straight 18v power supply (powershot) it's either working.....or not.  No intelligence, no extra features or sensors to worry about failing --- just good old power source that is capable of supplying 18v as designed/engineered.  Why do you feel the need to have an intelligent powershot versus one single straight 18v that works for short and/or long Ethernet cable runs?  Thanks.

As I mentioned earlier, we are working to have higher power voltage adaptor and with intelligent powershot that can dynamically adjust the power supply based on cable length sensed. So it will be one universal AC power adaptor.   Alex sB Tech Support     -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Jack Berridge Sent: Wednesday, June 11, 2003 9:37 PM To: '[EMAIL PROTECTED]' Subject: RE: [smartBridges] POE, voltage range Curious.  If you highly recommend using smartBridges power supply for smartBridges devices, why doesn't smartBridges have a power supply and PoE solution that works to the maximum Ethernet cable specs (~300 feet)?  Why even have the 12v power supply?  Why not have an 18v power supply that will work with the 50' or less cable runs as well as the longer cable runs?  At least for the outdoor (WISP type) solutions.  Other vendors we work with use the higher end (18v, even 24v) power supplies and it works for the short as well as the long runs.  It just seems that the 12v has caused your user community more problems which are resolved by going to 15v or 18v solutions......why not have an 18v be the normal (default) solution for outdoor smartBridges solutions? Thanks.
