| Note: Type A (Phy A) or Type B (Phy B) connectors are |
| usually distinguished by a marking on the male ST (i.e. if |
| using a blue ring to route transmit signals from the 4811, |
| do the same for all other devices). CN1 is keyed for an A |
| type connector, and CN2 is keyed for a B type connector. |
