Nish...thank you for the reply. We believe our cases of 'ethernet burnout' has been caused by inductive pulse (from nearby thunderstorms) in some cases as well as faulty power supplies in other cases. Also, I heard that SB determined the capacitors on the ethernet side were undersized (can you confirm?, was this fixed?). I agree that shielded CAT 5 is the way to go. Since SB is recommending this it only makes sense that you modify the design of the ABO to accept an enclosed CAT5 connector since the 8 inches of CAT5 you have hanging out of the units is not shielded. Stray (EMP) current could induce itself in those 8 inches of exposed wire, correct?

Bobby, The list had coined the phrase "Ethernet Burnout" for all problems that had something to do with the Ethernet port failure. We brought back a whole bunch of devices back to our lab for analysis. Some time ago I had published a report on our RMA activity. Many of the failures seemed to be related to crimping, water in the connector or cable etc. This is what we mean by "improper installation". John Hokenson has been a big proponent of using shielded CAT5 cable to address the EMP related failures. It is a logical recommendation. Based on some of these observations our Support Team had published these recommendations - http://www.smartbridges.com/pdf/ideal_installation_guide.pdf Hope this helps.

Nish....not sure what you mean by "higher voltage power adapters". We use the adapters that come in the box with the radio. Also, please elaborate as to exactly how, in your opinion "improper installation" can cause "Ethernet Burnout". Please provide example(s) of "improper installation" that would lead to "Ethernet Burnout". Also your comment about "we identified opportunities to improve and they have been implemented for some time now"; our experience is that the ABO's are just as susceptible to Ethernet Burnout as they've always been.

We have thoroughly investigated the "Ethernet Burnout" issue and conclude that most of those issues were caused by using higher voltage power adapters. A few others may have been due to EMP or improper installation. During the investigation we had identified opportunities to improve and they have been implemented for some time now. You may want to look at the aBO again. Ps. You may recall that the list has been quite for a while on this issue.

Just got off the phone with EC. They are totally out of ABI's and API's. They have 500 ABO's. We don't want the ABO's because of the "ethernet dying" problem.

Electro-Comm has only one June shipment sitting in their warehouse waiting for the new CDs with the new firmware. The CDs will reach them on Monday. In the mean time they have received many other shipments with hardware fix and these units do not require new CDs. We have removed shipment hold as soon as we started shipping the reworked units.

Will you still be asking Electro-Comm to put all units on hold until you furnish CD's with the new software?
