Test Note Fault/Alarm Relay Test Points Connector/Pins
1 TX FAULT J8/Pin 2 (NO), 1 (COM), 6 (NC) ****
2 RX FAULT J8/Pin 5 (NO), 4 (COM), 9 (NC) ****
3 UNIT FAULT J8/Pin 8 (NO), 7 (COM), 3 (NC) ****
**** A connection between the common and N.O. contacts indicate no fault/alarm.
** The IF output is only affected if that particular FEC card is currently passing traffic.
