Connections with the IES-3000
When you use the Ethernet extension card with the IES-3000, use the lower set of connector labels. They are
labeled 1 to 16 from left to right. Connector 1 is for connecting to the line card in slot 1; connector 2 is for
connecting to the line card in slot2 and so on. One connector is labeled 8/9 since the EEC1020 itself goes in either
slot 8 or 9 and a line card can go in the other.
