Cisco Systems 6200 appendix SLC 8DMT LEDs, Color Condition Indicated

78-5296-02 10/02/98			Hardware Description 1
	Table 1-11	SLC 8DMT LEDs
	LED	Color	Condition Indicated
	POWER	Green	The SLC is receiving power.
	READY	Green	The SLC is experiencing no problems.
		Yellow	At least one port on the SLC is in line test mode.
		Off	The SLC is not communicating with the MPC. This is the case when
			• The SLC is initializing.
			• The SLC has a hardware problem. If the READY LED is off for an extended
			period when the POWER LED is on, see the Cisco 6200 User Guide for
			instructions on troubleshooting the SLC.
	PRIME	Green	The SLC is using the primary (A) bus to move information across the backplane.
	SEC	Green	The SLC is using the secondary (B) bus to move information across the backplane.
			(Redundant systems only.)
	Ports 0 to 7	Green	The following conditions exist:
			• The port is receiving good signal levels (no loss of signal, or LOS) from the CPE.
			• The port has frame alignment with the far end CPE (no loss of frame (LOF) or
			severely errored frames (SEC)).
			• The SLC has HEC alignment in the upstream direction.
			• The modems on both sides have negotiated the loop rates.
			The port LEDs remain lit (green) in the presence of occasional minor alarms.
		Flashing	The port is enabled and is trying to communicate with the remote CPE. (That is, the
		green	port is training or preparing to train.)
		Off	One of the following conditions exists:
			• The port is experiencing an intrusive DMT hardware test.
			• The port is disabled or is not configured.
