Client with a SEXTANT had no more internet, antenna was not connected to AP.
Send technician; antenna was dead. Nor with power adapter, nor pocket 18V batter unit would start.... bad news..
In the office prepared new one and told tech to bring in the old one.
First thing we always do is check if failing unit indeed fails, so we connect to our workbench setup....
BANG! a big spark and some smoke from the ethernet connector when the ethernet plug with poe (24V) was connected.
Well, that unit must be dead....... eeehhhhh, board boots up...? Checked PC, winbox loader... yes board is running!
Logged in, checked everything... all systems running!
Disconnect unit since two more times, two more time no more light effects, normal boot procedure, running fine.... how weird..
Gave board closer look, some spider rags around... but no dead or cremated spider.... so what happened we don't know, but the unit is back reday for production! A real chock treatment!
