Types of Troubleshooting Methods
Description
The system LEDs (on the operator panel) indicate any system or
hardware error detected during initial diagnosis or system
operation. Additional LEDs are provided on the XSCF Unit, power
supply unit, fan unit, and other units so that you can always locate
faulty components and identify specific errors.
System messages are often displayed on the system console. These
messages can alert you to system problems, such as a device that is
about to fail.
You can use the XSCF Shell to find details of an error state, the
device status history, and other status information.
