• Port status LED on System hub/switch should light when the Ethernet cable is plugged
in between the hub/switch and the serial/Ethernet board.
• Ribbon cable (if used) seated properly on the hall call driver and the serial/Ethernet
board.
• Use a voltmeter to measure between each of the three DC voltages (3.3V, 5V, 9V) on
the serial/Ethernet (SC-HCE) board to ground. Voltages should read the provided
level, +/- 10%.
