Overview of Online Offline Diagnostics
The Online Offline Diagnostics is a field diagnostic mechanism that allows the customers to test and verify
the line card hardware problems.
To perform a hardware diagnostic test on a line card in the Cisco cBR universal broadband router, download
an OOD Field Diagnostic image for free from Cisco.com and use it to verify if the line card problems are due
to hardware failure. The customer can run field diagnostic tests on the standby line card at any time without
interrupting service. Testing the standby line card improves high availability of the system by ensuring the
standby line card is ready for a switchover.
Field Diagnostic Image Information
Field Diagnostic image is used to run diagnostic tests on a line card and is available from Cisco.com.
First, download it from Cisco.com to one of the flash file systems on the router. Then move it to the line card,
and the line card is automatically taken offline. Once field diagnostic tests are complete and the test results
are gathered, the Field Diagnostic image must be unloaded from the line card. Normal line card operation will
automatically resume after the Field Diagnostic image is unloaded from the line card.
