Description and Action

 

 

 

 

On

 

The power supply is on and operating correctly.

 

 

 

 

Off

 

There is an AC power problem. Possible causes are:

 

 

1. There is no AC power to the power supply.

 

 

Verify these items:

 

 

a. The electrical cord is properly connected to

 

 

the device.

 

 

b. The electrical outlet functions properly.

 

 

2. Disconnect the ribbon cable from connector J25

 

 

on the system board. If the AC power LED comes

 

 

on, see the “Undetermined Problems” section on

 

 

page 5-25.

 

 

3. The power supply has failed and needs to be

 

 

replaced. Have the system serviced.

 

 

 

 

System Error LED

If the system error LED on the front of the device is on, one or more LEDs inside the device might be on. Use the Light Path Diagnostic panel to quickly identify the type of error that occurred. For LED locations, see Figure 5-1.

Your device is designed so that LEDs remain on when the device shuts down as long as the power supply is operating properly. This feature helps you to isolate the problem even if an error causes the device to shut down.
