DETAILED STEPS

	Command or Action	Purpose
Step 1
	Apply power to the second LCC.	Starts up the LCC.
		• Allow the chassis to fully boot.
		• Verify that “IOS XR RUN” appears on the RP
		faceplates.
		• In each FCC, verify that the indicator LED on the OIM
		LED panel is green for each fabric cable connected to
		the non-DSC LCC.
		• The LCC loads any necessary software and
		configurations from the DSC, including the rack
		number and appropriate Cisco IOS XR software
		packages.
		• Do not proceed until both RPs in the LCC display
		“IOS XR RUN.” This indicates that the RP has
		successfully loaded the Cisco IOS XR software.
Step 2
	show controllers fabric rack all detail	Displays the status of all racks in the system.
		• In a properly operating system, the rack status for all
	Example:	racks should be Normal, and the server status should be
	RP/0/RP0/CPU0:router(admin)# show controllers	Present.
	fabric rack all detail
Step 3
	show controllers fabric plane all detail	Displays the status of all racks and additional information
		for racks in install mode.
	Example:	• Wait for the status in the Admin State and Oper State
	RP/0/RP0/CPU0:router(admin)# show controllers	columns to change to UP for all planes.
	fabric plane all detail
Step 4
	show controllers fabric connectivity all detail	Displays the LCC cards that can communicate with all eight
		fabric planes.
	Example:	• The expected output should contain a series of ‘1’s for
	RP/0/RP0/CPU0:router(admin)# show controllers	each of the fabric planes active in the system. If a fabric
	fabric connectivity all detail	plane is administratively “shutdown” the output of the
		command above remains the same. If the fabric card is
		physically removed or powered down, the “1” changes
		to “.”
