Identifying Problems Using Trouble Indicators and Status LEDs

If the system error LED on the front of the device is on, one or more LEDs inside the device or on the power supply will be on. Your device has LEDs to help you identify problems with some device components. These LEDs are part of the Light Path Diagnostics feature built into the device. By following the path of lights, you can quickly identify the type of system error that occurred.

Your device is designed so that any LEDs that are on remain on when the device shuts down as long as the AC power source is good and the power supply can supply +5 VDC current to the device. This feature helps you isolate the problem if an error causes the device to shut down. (See Table 5-4.)
