Ok, clarification, this still might be a power issue, checking on this...

  I'm awake again.   Apparently these are the stock 820c ac power supplies.

    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.

    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?

    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?
