Dale & I went up to BawFaw today to assess the outage situation today. Due to a cable failure at CapitolPeak, BawFaw was running on its backup link via Larch Mtn. Then, this path failed too. Here's the culprit: https://photos.app.goo.gl/ZBKyrkJRA5sJdTVr7 That's the result of water getting into the cable (jacket penetration), and then running down to the RJ45 PoE injection point. With those contacts submerged and 24V present, the copper begins electrolysis. This ruins both the cable end, and the PoE injector. Luckily, I brought spare injectors, and my crimping kit. Two injectors were swapped out, and this Larch RJ45 was re-terminated. Water started dripping out of it immediately though! To combat the outdoor jacket breach, I installed "drip loops" at the bottom of the cabinet for every one of the CAT5 cables coming in. You can see the Larch cable drip loop here: https://photos.app.goo.gl/exgP2ozmKJuppsTq7 Notice the puddle already forming! The ground wire keeps the shield integrity from end to end. I think the cause of the outdoor CAT5 jacket destruction may have been improper installation. The lowest 10-20ft of cable didn't have any cushions, and were swaying pretty significantly in the wind, hitting metal edges. Dale remedied this situation a little bit by sticking the HamWAN cable bundle into some free space of another tenant's cable hanger. We didn't bring cable cushion hardware and weren't planning on climbing the tower, so that's all that could be done. BawFaw should stay online for a little longer now, until we can properly address the cable system. --Bart
