Re: [AFMUG] PTP820C radios not booting up - ideas?

Agree, could be inadequate power. when activating the second core, it takes more power.. we have tried using sync injectors, work with 1 core, too much load for 2nd core.   Roland     > Sounds like a watchdog timer or a power supply overheating and folding.

If I'm reading this right, it worked at some point where you could configure it? This implies that something is wonky in your configuration. If you have it connected to a Mikrotik, you could scan for IPs and/or MAC addresses to see if it somehow is changing its IP or something. Is someone onsite to check, or is this all happening remotely? bp <part15sbs{at}gmail{dot}com> On 2/17/2018 3:19 AM, Forrest Christian (List Account) wrote: So we have a new (i.e. put into production in the last couple of days) pair of 820C radios. I discovered earlier tonight that XPIC was not enabled on the radios, limiting throughput. In the process of enabling XPIC, we made some changes to the config, rebooted both ends, and now neither end will boot fully. We see the interfaces come up for about 30 seconds every 2.5 minutes, then they drop off and the cycle repeats. We've tried power cycling both ends. We've tried powering off one end in hopes it was related to the radios talking to each other. We have also attempted to get in with the 'splitter cable' on the management port. Using the provided IP addresses, we get a few pings out of the radio each cycle on the 'recovery port' (like 4), but are not able to start a web session at all. I haven't put a packet sniffer on it to see if it responds to the SYN packet or not, but it sure doesn't seem like it even starts a connection (just times out). In the hopes that SNMP was coming up during this time and I could issue a config reset via SNMP, we also tried to do a SNMP put and a SNMP get (at different times) with the community string we configured the radios with, and it seems like SNMP is not responding either. I'm going to get some sleep now, and try again tomorrow. We've opened up a ticket with Cambium support but I'm not getting any meaningful response out of them, and because of the timing, they're unable or unwilling to escalate beyond level one. I'm hoping someone has been through this and knows the magic solution.... Any ideas? -- Forrest Christian CEO, PacketFlux Technologies, Inc.
