Two gigabit switches of identical brand and model (D-Link GO-SW-8G 8-Port) are connected. This model shows a green LED light in gigabit mode, orange in 100 mode.
The two switches connected with the cable show green on one end, orange on the other end of the cable. Both switches are connected to other 1000BT and 100BT devices, so both do work in both modes. This happens with a homemade cable as well as a pre-made Goobay CAT 5-2000 U/UTP GELB 20m PL CAT 5e network cable.
What does it mean, that they show different colors on the two ends of the cable?
