Powering On the System

	To power on the system:
	1. Check all connections.
	2. Turn on the power supplies by pushing the ON (—) switch for
	each supply. (ON is indicated by “—” and OFF is indicated by
	“O”.)
Power-On Sequence	As the system powers on:
	■ Cajun v4.1.x (or later version) displays on the 8-character
	LED display on the front panel of the switch.
	■ On properly functioning modules, Port LEDs will cycle from
	yellow to normal operating status as the system continues
	through its power-on diagnostics.
	When the system has completed running its internal diagnostics, the
	8-character LED display should read:
	Cajun v4.1.x (or later version)
	The LEDs should function as described in "Interpreting Front Panel
	LED Displays " in the Cajun P550/P220 Switch Operation Guide. In
	general, you will observe the following on properly functioning
	modules (Table6):
