RB750G with dead ethernets

Thu Mar 20, 2014 1:24 pm

Hello,

I have RB750G.

When I power it on, the PWR, ACT and ETH5 leds are on. After approx 3 seconds the ACT led is switched off. Connecting the cable to whatever port does nothing. Changing the PSU, using different cables, trying to reset by reset button or switching it to netinstall mode does nothing. At whatever mode, the ethernets do not respond – tried against PC, switch and other mikrotik devices. Ethernets are just not switched on when cable connected. And, ETH5 led is still on.

What should I do?

Thank you.

Looks like a hardware defect to me.

Sometimes also eth4 led lights together with eth5 led, sometimes eth4 led lights alone. But mostly only eth5 led lights alone. I have checked the capacitors, seem not inflated, so probably they are fine. I have no other idea what to do.

I already did. Support suggested to contact local dealer. No answer from them so far. Anyway, thanks that you care.
