   |                    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.                                      |

   | Note:On NICs that have twisted pair connectors LED 4       |
   | designates the state of the connection, while on NICs that |
   | 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.                      |
