I have about 80 online routerboards all models RB333, RB433, RB433AH, RB600…
I have problem with routerboard dying…
I have grounded RB’s, lighting protectors, surge protectors, ups but nothing helps…
On few locations weekly/bi-weekly die about 1 router. Cards are RB52, RB52H and CM9.
RB and cards die at same time. For example today died 2 of my RB600 and 6 cards I can see that on circle board element PL901 (1R0) is melted.
On cards often I can see brown spots on passive cooling.
Please help… Monthly I lost about few thousands of dollars…
they are not wet, condesation is okay. I mainly use expensive Rittal enclosures but nothing helps.
It’s not rust it like short-circuit on metal..
The funny thing this happens randomly when it starts it happens about 3-4 times in 2 weeks and it stop dying for few months
Today I’ve replaced my 2 dead RB600 with RB600 and RB433 and for about 7h died both RBs…
But this time on RB600 all radio cards and RB600 died, I’ve found some spot on some circuit like fire, and RB433 died all ethernet ports and cards are OK…
Are you running the power too low - boards will overheat if the amps are out of wack.
Also - is your grounding really really good? I had a lot of problems on my towers until I realised the grounding at the power poles was not handling the load and my hardware was taking the hit.
I regrounded the utility poles and ran heavy cable to the tower grounds.
2007 I lost 25 towers - several repeatedly.
Last year - 3 towers and no repeats.

Does all RB’s need to be grounded? I understand that it might help when lightning strikes. And maybe static. No-one here realy use grounding measures.The highest voltage i use is 24volt. That is what the mikrotik dealers sell. I think 48v is 2 high. Senao’s usually use that much power. How is the weather conditions?
