Network Wiring (Chapter 6)
• Ensure all Ethernet or ARCNET and EIA-232 cards are installed and
addressed properly.
• Power up the BCU and observe the LEDs on the Ethernet or
ARCNET cards for proper operation.
• ARCNET LAN only: Ensure that the ARCNET card is going through
its power-up reconfiguration (recon) and is communicating with other
network devices. With the ARCNET cable connected, the green LED
should light steadily and the yellow LED should flash when data is
transmitted or received. If the green LED is flickering, the ARCNET
cable (or tee) either is not connected or is not working properly.
BCU Modem Installation (Chapter 7)
• Ensure that the internal modem card is installed and configured
properly.
