Table 6. LED status indications and recommended actions (Continued)

LED	Location	Color	Status	Meaning
CLK ERROR	Front	Yellow	On solid	• Primary Reference clocking source has been lost and the 6511RC is
	panel			using the Secondary Reference as its clocking source. Matrix Switch
				operation should continue unimpaired.
				• Visit the System Clocking Overview page and examine the current
				clocking configuration and status.
				• Use the clocking configuration and status information to determine
				the appropriate course of action to restore the Primary Reference
				clock source to operation.
			Flashing	• Master Clock source and the Secondary Clock source have been lost
				and the 6511RC is using its internal crystal for its clock. Matrix Switch
				operation should continue unimpaired.
				• Visit the System Clocking Overview page to examine the current
				clocking configuration and status.
				• Use the information in determined the appropriate course of action to
				restore the Primary Reference to operation.
			Off	No clock errors currently detected. No action recommended.
TEST MODE	Front	Green	On solid	The STM-1 port is currently operating in some test mode.
	panel			No action recommended.
			Off	None of the G.SHDSL ports is operating in test mode.
				No action recommended.
WANa	Front	Green	On solid	Indicates the STM-1 port is activated, synched, and operating normally.
	Panel			No action recommended.
			Single	Indicates that the Model 6511RC is detecting the SDH network, but is
			Flash	unable to synchronize with it.
				• Verify the STM-1 cables are fully and correctly connected.
				• Examine the SDH Configuration page and ensure each parameter
				value matches the corresponding value in the connected SDH net-
				work.
			Off	• Indicates rear module not present or STM-1 port is not configured.
				• Ensure rear module is incorrectly installed; install if absent.
				• Examine the SDH Configuration page and ensure each parameter
				value matches the corresponding value in the connected SDH net-
				work.
ENET	Front	Green	Flashing	Indicates there is Ethernet frame activity on at least one of the eight PICMG
(SWITCH)	Panel		or	2.16 connections to other blades on the PSB bus.No action recommended.
			On solid
			Off	Indicates no Ethernet frame activity detected on the PICMG 2.16 bus.
				No action recommended.
ENET(REAR)	Front	Green	Flashing	Indicates Ethernet frame activity on one or both of the 10/100/1000
	Panel		or	Ethernet ports. No action recommended
			On solid
