I came through a strange experience 1st time ever with mikrotik. i have got a point to point wireless link..suddenly this link went down. after doing a troubleshooting i noticed that one mikrotik was not working ( no power, no activity, no beep sound). then i took RB out of the box and give power supply directly through adapter. immediately the mikrotik boot and i heard a beep sound also. but still i cant see it in winbox. then i insert the cat5e cable directly on the RB Ethernet port. instead of inserting it out Ethernet port of the box(casing), and i now able to ping and see it in winbox.
means that when i insert cat5e cable directly into the Ethernet port of RB it is working but if i connect it with POE or Ethernet port of outdoor casing.
where is problem? is there is problem in Ethernet port of RB. is something is short in RB or is Ethernet port of RB is half damaged and not supporting the POE.
thx n regards.
