10.1.4.3. Relay Board Status LEDs

There are eight LEDs located on the Relay Board. The most important of which is D1 is the most important LED, which indicates the health of the I2C bus. If D1 is blinking the other faults following LEDs can be used in conjunction with DIAG menu signal I/O to identify hardware failures of the relays and switches on the relay (See Section 6.9.2 and Appendix D).

Table 10-4: I2C Status LED Failure Indications

	LED	FUNCTION	FAULT STATUS	INDICATED FAILURE(S)
