Ethernet Controller board) to the ground lug at the side of the Series 90-70 PLC rack.
(See Figure 2-2).
Warning
The ground wire must be securely fastened to the chassis of the Series
90-70 PLC rack and the rack must be properly grounded. Failure to do
so may cause personal injury and/or improper operation of the LAN.
6. Connect the transceiver cable into the 15-pin AUI Port of the Ethernet Controller
board. Secure the cable with the slide latch mechanism. The other end of the
transceiver cable should be connected to an external IEEE 802.3 compatible
transceiver which is attached to the Ethernet network. SQE must be enabled on the
transceiver.
7. Set the CPU Run/Stop switch to STOP.
