All, I just finished my third try to insert my first routerboard/routerOS system into my WISP network! First time, I thought it was one of the 3 radios I was using (see previous thread http://forum.mikrotik.com/t/rb153-flashing-blue-led/11303/1 ).
The second time I had a senao nmp2511, an SR2, and a CM9 radio, and it kept rebooting. I noticed the 2 beeps on bootup had a weak (lower tone) second beep.
Third try:
Thinking it was a POE/power supply problem, I went straight to the power plug with a good 48V supply. No flashing blue leds, no funny sounding beeps, however, on one of its reboots, it beeped 3 times. It kept booting up, one beep, then 50sec later 2 beeps. Everything came on, 2 radios carried ~400Kb backhaul traffic, AP associated with 16 CPEs. Then reboot. During one of the 2 minute uptimes, I quickly logged in and disabled all watchdog stuff. When the next event happened, the unit was unresponsive for 3 minutes. At that time I HAD to fall back to my 3yr old sokeris board system.
BTW, I have 2 rb153s, and did try 1 with one I burned in at home for a week, and trys 2 and 3 with a fresh board.
I can’t reproduce this on the bench, and I don’t want to keep inflicting these outages on the 45 customers affected. help!
I believe there’s some issues with some RB153’s fully loaded, some bus/clock/sync problem, whatever. Try with a RB532 and if this works you propably have a faulty unit you should RMA…
both of the rb153s have been powered on several days at a time on the bench without reboot. (single hotspot user testing) It only happens with real traffic. Any pointers to more rb153 failure info? Thanks
As i said fully loaded, meaning also with traffic I only have my information from a case where another distributor have a lot of those boards high up in the air malfunctioning, nothing in the forums except for people experiencing funny stuff with RB153 as you can read in other posts.. Guess this is why we cant get those boards at the moment…
