The PHY is the physical layer. It's the chip that converts |
| 10 |
logice signals to something that can be sent via copper wire |
| 11 |
or, in other cases, optical fiber. |
| 12 |
|
| 13 |
Typically, most modern ethernet setups consist of the Ethernet |
| 14 |
chip - MAC (that has the MAC addr) and a PHY chip. So the PHY |
| 15 |
chip connects to the RJ45 jack and may sense a carrier and |
| 16 |
light the LED indicating such. But the interface between |
| 17 |
the Enthernet chip (MAC) and PHY can also have breakage. |

That's odd. Though, it could be the control side of the |
| 29 |
ethernet chip is not working, but it does auto-sense the |
| 30 |
ethernet and setup correctly. |

Some defs - |
| 33 |
|
| 34 |
MAC - Media Access Controller (Ethernet chip). |
| 35 |
MII - Media Independent Interface. The interface |
| 36 |
between the MAC and the PHY. |
| 37 |
PHY - Physical Interface transceiver - connects to the |
| 38 |
RJ45 jack. |

There's a few pdfs out that there. Searching for - Ethernet MII |
| 41 |
brought up the one from Electronic Design. |
