Note: POST diagnostics only display a voltage/temperature warning or failure. It does not result in an error. Voltage/temperature failures cause router shutdown after the router has booted.

Problem: The system hangs after the “All diagnostic tests passed” message or while scanning devices.

Solution: Follow these steps to resolve the problem:

1Verify there are no SCSI address conflicts.

2Check the connected SCSI devices to make sure everything is properly connected and SCSI termination is correct. See Restoring the Default Configuration Through the Flash Utility.

3If the devices work properly, replace the router.
