Title: RE: [smartBridges] POE flakey???

Sully, Thanks for the detailed observations. On the surface this does not sound logical. But with so many of you chiming in, our Product Engineering guys have started to work on the issue and they already had a meeting with the supplier to tighten the tolerance.   Establishing a conclusive link to dis-association problem may take some time. Do you happen to notice if the Blue light was flashing when the units had lost association?   The RJ45 boot issue was fixed a few weeks ago. The supplier has been asked to use software material for the cover.   Nish     -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of The Wirefree Network Sent: Friday, July 11, 2003 2:06 PM To: '[EMAIL PROTECTED]' Subject: [smartBridges] POE flakey??? Lost association   More info:  My 3rd and final misbehaving airBridge is now fixed.  I was JUST about to climb the roof for a radio replacement when I decided to try something first.   First thing I noticed on this unit, which has been down for 1.5 days, is that the Ethernet light on the NIC was not illuminated.  That initially had me thinking the airBridge was bad.  I then unplugged the chrome power cable from the POE unit and plugged it back in.  I instantly got my green light on the NIC again and was able to ping the airBridge again.  A couple seconds later I regained association and was able to surf.   I then unplugged the chrome power connector and plugged it back in again.  I lost association (obviously), but did not gain it back.  I did this while having 2 DOS windows open and a constant ping to both the airBridge and the Gateway.  The airBridge would always regain its ping response immediately after restoring power...but the association would sometimes not come back (the ping back to the gateway).  So...I continued to play with the plug until I found a very small "sweet spot" where if I unplugged the chrome connector and plugged it back in (while in that exact small sweet spot), the unit would regain association every time.  However, anywhere else around the 360 degree axis would not.   So...I tried another POE unit (with same wall power supply) and tried this all over again.  The new POE unit worked better but not flawlessly.  This unit had a VERY large sweet spot and very small bad spot (opposite of other POE unit).  So...I made a couple white hash marks on the chrome connector that ensures that I always had the alignment correct when unplugging and plugging it back in.  When properly aligned, the unit would always regain association.   So...I believe the radio is good and the POE is crap!!!!   Hope this info helps some others from pulling there hair out...or going through the RMA process for radios.   Sully -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of SB Tech Support Sent: Thursday, July 10, 2003 8:06 PM To: [EMAIL PROTECTED] Subject: RE: [smartBridges] POE flakey??? Thanks for pointing up the quality issue on our Powershot PoE. We will address both of the issue (no power or bad Ethernet connection) and with better quality check at the factory. We also will look into changing the “hood” to softer PVC material so that it is easy to press.   sB Tech Support   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of phantam Sent: Friday, July 11, 2003 10:05 AM To: '[EMAIL PROTECTED]' Subject: RE: [smartBridges] POE flakey???   We need a SB response to this issue. -----Original Message----- From: Blaine Fleming [mailto:[EMAIL PROTECTED]] Sent: Thursday, July 10, 2003 9:55 PM To: [EMAIL PROTECTED] Confirmed.  I have had this issue since the first one I bought. --Blaine   At 10:45 AM 7/10/2003, you wrote: >sB...this may be something for you to look at closely. > >I was troubleshooting a clients bad airBridge unit last night and noticed >something flakey about the POE unit. > >Hope I can describe it... > >If you follow the wall plug wire up to the point where you can >connect/disconnect it from the POE unit there is a chrome plug.  Out of >the box, this is initially unplugged. > >While you are looking at your connected/associated sB product...hold that >chrome power plug in both hands (one on the power plug side and one on the >POE side) and twist it 360 degrees around axis.  You will notice that the >power goes on and off.  I did very small tweaks (rotating the chrome plug >around axis) until I actually found a spot that would cause the sB unit to >go (and stay) offline (noticed the Ethernet 10 Meg connection go offline >"Cable Unplugged").  I then tweaked it a bit away from that position and >it would go back online ("10 Meg Cable connected"). > >I was logged into the sB product (in my case airBridge), and when I would >twist this connector, it would lose association (obviously...due to loss >of power) and then twist it back and it would reassociate. > >I tried this with several POE units and power cables.  All with the same >results.  Given some more time, I will have to check the POE power pins >and see if there are "sweet spots" on this chrome plug that allow the full >12 volts to pass.  Or vice versa. > >Can someone else confirm my findings please?? > >Sully >The PART-15.ORG smartBridges Discussion List >To Join: mailto:[EMAIL PROTECTED] (in the body type subscribe >smartBridges <yournickname> >To Remove: mailto:[EMAIL PROTECTED] (in the body type unsubscribe >smartBridges) >Archives: http://archives.part-15.org The PART-15.ORG smartBridges Discussion List To Join: mailto:[EMAIL PROTECTED] (in the body type subscribe smartBridges <yournickname> To Remove: mailto:[EMAIL PROTECTED] (in the body type unsubscribe smartBridges) Archives: http://archives.part-15.org
