3-12. FAULT INDICATORS (cont)
Each circuit card assembly includes a fault indicator that
lights whenever one of its fault sensors detects a failure.
Only one logic card fault indicator will light at a time. The
priorities are Transmit 1, Transmit 2, Receive 1, and Receive
2. For example, if both Transmit 1 and Receive 1 contain a
fault, only the Transmit 1 fault indicator will light. When
the fault on Transmit 1 is corrected, the fault indicator on
Receive 1 will then light.
The card indicators can be seen by removing the appropriate
access cover (left POWER SUPPLY cover for the power supply
cards and right LOGIC cover for the logic cards).
