It will fry the electronics. Ethernet is not intended to carry any significant current on the TX/RX pins. Applying 120 VAC to those pins will almost certainly cause the current to exceed the limits.
- oasisbob 12y agoIt isn't strictly true that Ethernet separates data pins from power pins. Because the data transmission is differential, you can send power over the same cable. (The audio world has been using phantom power for years over XLR cables -- its not a new technique.) eg, Gigabit Ethernet has no unused pins, and can still support PoE.
- function_seven 12y agoThat's true, I should rephrase it as "Ethernet is not designed to carry any significant current. On any pins. At all. So don't connect your twisted-pair to your two-prong."
