I see nothing on the video, so can’t comment on that, but could you test the switch by connecting a router to the 1st port and a notebook to every other port one by one, to check whether the devices talk to each other?
I assume that the router acts as DHCP server, and the notebook is set to DHCP address lease, so no additional configuration is needed…
Tried with with different cables again and tried to connect a notebook and a raspberry pi. I’ve also tried every single port, but nothing shows up on the devices and no LEDs flash/blink. :(
There is no reset button since it is an unmanaged switch, so it’s just plug and play. I’m sure it gets proper amount of power. The support now just told me that the best would be to just get a replacement.
Considering how close the vehicles are to the bridge height, I wonder how many were inaccurately measured. Like the truck for an example. The driver might have been told that the cargo space was 12ft tall, and so it should have fit just fine. However, in reality the height of the truck is actually 13ft, so a few inches gets taken off the top.
Oh, I didn’t realize that was specifically telling the drivers in the video that they were too tall. I thought it was just a general warning to anyone passing through.
No, it actually measures vehicles if they’re short enough to pass. My guess would be a IR receiver-transmitter combo with a simple “flash if tripped” circuit, but still, that is enough to draw the driver’s attention.
Originally, there was a pair of flashing lights next to a sign that said “Overheight when flashing” that would light up if the sensor was tripped. Then they replaced it with traffic lights that would stop traffic and flash “OVERHEIGHT MUST TURN” like you see here if the sensor was tripped.
Of course, that caused the dumb truck drivers to just floor it and run the red light.
