Web100 base ethernet uses some quarter phase magic, so yeah polarity is important. 100Base-TX uses MLT-3, which only cares about transitions. The polarity doesn't matter. 10Base-T is the same way. Time to make a few test cables and try every pairing of devices in the house! WebMost PHYs, including the KSZ8081, will immediately negotiate a link with no configuration from the host as long as the pins are strapped correctly. You can verify this through the SMI. If the SMI shows a properly negotiated link, then the hardware should be working.
