Ethernet Uplink Light?

Post by alansrobotlab » Sat May 16, 2020 9:49 am

Hey there,

I have a few C4s on my testbench, and with all 3 I'm not seeing an uplink light when plugged into Gb ethernet.
The activity light on the right does blink, the uplink light on the left is off.

I've tried two different switches, with both the 4.9 and the 5.7 kernels, and two different cables.

Other than the uplink light everything seems to be working fine.

What's the colour of the LED on or blink?

Here's a quick clip:

(For what it's worth, I'm not seeing any voltage across the uplink led)
