You can run field diagnostics to help isolate a faulty line card without disrupting the operation of the system. Field diagnostics are not designed to identify specific components within the router.
Chapter 6 Router Field Diagnostics Diagnostics Overview • Easy access to the most current diagnostics software—Because the field diagnostic software is now maintained as a separate image, the most recent version is always available on Cisco.com, without regard to the Cisco IOS software release currently in use.
Chapter 6 Router Field Diagnostics Field-Programmable Gate Array Overview Diagnostic testing stops when all of the tests are completed, are terminated by the user, or by default if an error is encountered. If multiple cards are specified for the test cycle, the diagnostics stop testing a card when it fails a test, but then continues testing the remaining cards. When testing is finished, a pass or fail message appears on the console, and on the alphanumeric LED display on the card being tested.
Chapter 6 Router Field Diagnostics Field-Programmable Gate Array Overview Some FPGA images are bundled within the Cisco IOS image and are updated along with a new release. These type of FPGA images do not require flash memory storage and are developed and expanded within Cisco IOS feature sets. FPGA images stored in flash memory on the line card receive updates occasionally.
Chapter 6 Router Field Diagnostics Field-Programmable Gate Array Overview Note Before updating the next line card, wait about 30 seconds after the Cisco IOS software reloads on the line card to give the router a chance to synchronize all of its internal functions. Upgrading an FPGA Image on a Line Card When the Cisco IOS image boots, it verifies that a compatible FPGA image is running on the router.
Chapter 6 Router Field Diagnostics Field-Programmable Gate Array Overview Step 2 Enter the diag slot-number update-fpga source {tftp | flash} source-path command to update the flash memory. Where: • slot-number is the slot number of the line card you are upgrading. • source-path is the path to the diagnostic image. – For flash memory cards, the source path is typically: slot0:c12k-fdiagsbflc-mz.120-25.S or slot1:c12k-fdiagsbflc-mz.120-25.S.
