          |                    MISCELLANEOUS NOTES                     |
          |------------------------------------------------------------|
          | The jumper settings for the entire line of E1100 card are  |
          | exactly the same. To save space we have only listed these  |
          | settings once instead of including a table for each card.  |
          | The only differences between the models are the wiring     |
          | types and topologies.                                      |

          | do not have twisted -pair connectors LED 4 indicates if    |
          | power is applied to the card. LED 5 is present only on     |
          | cards that have two RJ-45 connectors.                      |
