SCE 2000	Description	Status LED State
Operational
Status
Warning	SCE 2000 is fully operational (as above) but one of the	Flashing orange
	following occurred:
	• Line ports (FE ports) to the link are down
	• Management port link is down
	• Temperature raised above threshold
	• Voltage not in required range
	• Fans problem
	• Power supply problem
	• Insufficient space on the disk
	Note: If the condition that caused the SCE 2000 to be in
	Warning state is resolved (for example, link is up) the SCE
	2000 reverts to Operational state.
Failure	System is in Failure state after Boot due to one of the following	Red
	conditions:
	• Power on test failure
	• Three abnormal reboots in less than 20 minutes
	• Platform configured to enter Failure mode consequent to
	failure-induced reboot (this is configurable using CLI
	command)
	Note: Depending on the cause of failure, the management
	interface and the platform configuration may or may not be
	active/available.

Problem Solving Using a Subsystems Approach

Identifying Startup Problems

Startup problems are commonly due to the source power or to a poor cable connection.

When you start up the SCE 2000 platform for the first time, you should observe the startup sequence described in the Starting the SCE 2000 Platform (on page 7-1). This section contains a more detailed description of the normal startup sequence and describes the steps to take if the system does not perform that sequence as expected. LEDs indicate all system states in the startup sequence. By checking the state of the LEDs, you can determine when and where the system failed in the startup sequence. Use the following descriptions to isolate the problem to a subsystem, and then proceed to the appropriate sections to try to resolve the problem.

When you start up the system by turning on the power supply switch, the following should occur:

•You should immediately hear the fans operating.
