Def open a ticket on that Jay. You mention the radio will power up with no wires... That isn't good. I would assume you have -48volts in use, but somewhere along the line things are messed up with that at a minimum IMO. You do NOT have to tie your + to the ground of the structure for these to work BTW. Or at least I was told that.
Personally, I would try and isolate the power to each EnB, and start with that. I don't think any of us can be sure of how you are really set up remotely. But, that alone would drive me nuts having to reboot the entire site for one EnB. A screwy power issue could cause a GPS fault I would imagine. And, I don't think the radios are supposed to transmit without that in place first and foremost I think. It's part of the boot up process. GPS, Then RF portion check (shorts,opens, etc.), then turn the radio on.

I'd like to throw our current problem out at everyone for opinions - let me know what you think please. Currently we have a three sector system. Lets call them .5, .6, and .7 .6 seems to operate flawlessly without any issues. out of .5 and .7 only one will transmit at a time. When we first purchased this system (February) all three sectors transmitted but they would also lock up several times a month requiring a reboot. The power supply in use, in my opinion, was a "home brew" power supply that looked like four or five computer power supplies run together. I have since learned (from someone involved in the initial installation) it was a FM broadcast power supply. Connect more power cords and you get more amps. Only two of the four power supply cords were really required but for a while all four were used. One "main" wire ran out to surge protectors where the current carrying wires split out into wires going to each individual radio. The only way to reboot one was to reboot the entire power supply which rebooted the 3 radios and the ASN. Fast forward a bit - the consultant (who is helping us build a radius server to move to integrate with powercode and intergrate with our network) also got with telrad and we determined the units were running firmware that was built for the LTE conversion but was not recommended for production use. Accidentally at one point the wrong firmware was loaded and rejected by the base stations (they would not even boot with it) but telrad told the consultant it was the wrong firmware and provided the correct firmware. This is the day that transmit problem started with .5 or .7 At the end of that day stabiliity had returned to the platform (no more random lockups) but one of those two units would no longer transmit. Initially they would not get a gps lock, or only one or the other would get a gps lock. We have tried slaving to the gps of the working unit (.6) but the problem still existed in one way or another. The consultant suggested we purchase a new power supply - one that could monitor amps and current - and we did so. After installing it we still had the same problem - - and we also found even if we disconnected all of the wires to a basestation that base station would still power up (but would not necessarily transmit) via the ground wire. The next step the consultant made was to replace all the power wires on the tower with factory made power wires. We did that yesterday - but there is still no change. I have suggested we engage telrad directly on this again (we are now one full month nearly with at least one of the three sectors down, we've lost probably 40 of 120 customers on the tower to disconnection - although I feel once everything is stabailized they will come back, the other options in the town are horrible) I understand this to be an extremely odd issue ; any thoughts? In our internal camp some of us are thinking we may be using overlapping frequencies - but I feel sure we have checked for that. I am sure we will check again. Jay Fuller Cyber Broadband Inc
