Chapter 6 Troubleshooting Processor Subsystem Troubleshooting Cable Interface Line Cards Check the following to help isolate a problem with the cable interface line cards: Step 1 Step 2 Verify that all cable interface card enabled LEDs are on. a. If yes, the system is operational. Check to see if all cable interface card enabled LEDs are off. a. If yes, verify that you are running a version of Cisco IOS software that supports the cable interface cards you are using. For the latest Cisco IOS software release information, refer to the Cisco uBR7200 series release notes, at the following URL: http://www.cisco.com/en/US/products/hw/cable/ps2217/prod_release_notes_list.html Step 3 Step 4 For the latest information on supported features, refer to the Cisco uBR7200 series software features guide at the following URL: http://www.cisco.com/en/US/products/hw/cable/ps2217/products_feature_guides_list.html b. If the Cisco IOS software is correct, contact Cisco TAC for instructions. Check to see if any cable interface card enabled LEDs are off. a. If the enabled LED on an individual cable interface line card is off, check to see if the cable interface line card has pulled away from the midplane. b. Reseat the cable interface line card in its slot. (You do not have to turn off the system power when removing or replacing cable interface line cards.) c. After the system reinitializes the interfaces, the enabled LED on the cable interface line card should come on. If the enabled LED remains off, the system detected a processor hardware failure. This LED should be on in normal operation. Contact Cisco TAC for instructions.
