[AFMUG] FSK AP thinks default plug is in
I'm pretty sure I've seen this question posted before, but I don't recall the verdict. We had a power outage last night that outlasted the batteries at a tower. When the power finally came back on, one AP didn't come back. Further investigation revealed that it seems to think there is a default plug in it, but there isn't. I've checked the default plug jack and there is nothing foreign in it, and the pins all appear normal. I've tried booting it with an actual default plug in it, and then rebooting with it out, thinking that perhaps that would reset something, but no dice. Is there some way to recover the radio when this happens? Craig
Re: [AFMUG] PTP820S 2+0 configuration
We haven't been able to determine this. Where we're seeing it is on a pair of Exfo test sets. We're trying to qualify a new 50 Mbps dedicated circuit using RFC 2544 testing using the Exfos. Tests are failing, reporting lost frames. The confusing thing is that our counters on both radios and switches are fairly clean. The radios report zero "defective blocks". The only errors I am seeing that I wonder about show up on both the radio and ethernet sides. On one radio, I see 38 "TX length error frame count" errors since Saturday on the ethernet port. I also have 38 "RX length error frame count" errors on the radio. On the other side, I have 39 "RX length error frame count" errors on the ethernet. None on the radio side. However, I question whether these errors are related to what I'm seeing in any way. I tested another leg of this circuit the other day. Identical radios. It tested clean, but was also showing some of these same errors. Craig Quoting David Milholen <dmilho...@wletc.com>: Are these frame losses on the Radio side or the ethernet side?

Re: [AFMUG] PTP820S 2+0 configuration
Thanks Daniel. This eases my mind a little since you are quite familiar with these radios. Here is the Cambium Community post I'm referencing. It's very clear that it means sub-bands: http://tinyurl.com/j6lrsea Thanks! Craig Quoting Daniel White <afmu...@gmail.com>: Craig my guess would be they meant frequency band, not subband. I can't think of any reason you couldn't use different sub-bands so long as the OMT covers the range (which in the case of 11GHz is most likely covers all subbands).

Thanks Josh. I'm looking at their checklist in appendix A. It requires you to choose what type of service will be in use, and provides a table of services to choose from. However, it doesn't show either part 15 or part 101. The closest thing that it shows is "subpart L of part 101", which is LMDS. I gather that this is primarily intended for PtMP installations.

[AFMUG] POE vs DC and surge supression
We've got some Cambium PTP820S radios going up shortly. We will be running fiber to the radios, so we're debating on POE vs. DC up the tower for powering them. We have been told by the tower owner that we need to adhere to R56 for lightning protection. Our initial thought was that we would just run POE since we already have the cable, and it would give us an out-of-band management port. But, according to the Cambium installation manual (and I think R56 specifies this too), it says that if we're running POE, we're supposed to bond the cable shield to the tower every 50 meters. I assume that means at the top and bottom since our cable runs are all less than 50 meters. In addition, the manual says that we should use Ethernet surge suppressors. We're thinking "what a pain in the butt". On the other hand, the Cambium manual does not address grounding for DC cable in any way other than saying that the radio has DC (and Ethernet) surge protection built in. So the DC option is looking pretty attractive compared to the hoops we'll need jump through for ethernet. I'm wondering if there's something we're missing that the Cambium manual doesn't address. I figured just to be safe, we would go ahead and put DC surge suppressors at the top and bottom of the DC cable. Is there anything else needed for R56 adherence in this situation? Craig

Re: [AFMUG] Dish polarity question
Okay. So, let me throw another wrinkle in the mix. I'm wanting to use an 8-foot Radiowaves dish that we've had in storage for this shot. Looking at the back of the feedhorn, there is a plate where the flexible waveguide attaches. That plate has a rectangular hole in it. However, I can see that underneath that rectangular hole the waveguide is actually circular. So, could I use an OMT with such a configuration? Would have have to replace that plate with one that has a circular hole instead of a rectangular one?

[AFMUG] SAF POE/Fiber question
I've got a few SAF Integra links that we'll be doing shortly. We're planning to run fiber to the radios. I'm wondering what's the best method for powering the radios? From what I gather, SAF has some sort of new kit where you can send power up to the radio on 2-wire DC cable. At the top, near the radio, there is a pigtail that takes power off the 2-wire cable, and puts it on another cable with an RJ-45 for plugging into the ethernet port on the radio. I have a couple of issues with this method. First of all, it appears they use a Bulgin outdoor coupler to make the transition from 2-wire cable to CAT5 cable. I've found those Bulgin couplers to be less than reliable over the long term with regard to water ingress. So that makes me nervous. My second issue is lightning protection over the DC cable. I'm sure there are products that are designed to protect DC circuits. What would you guys recommend for protecting a DC circuit running up the tower? Overall, I'm wondering what would be wrong with just running shielded CAT5e up to the radio for power purposes only? If we did that, we could just use the WB surge protectors. Is there some advantage to running 2-wire vs. CAT5 that I'm not seeing? Craig
