Fail LED blinks steadily | This is a user correctable problem. The steadily | |

|
| properly, unbroken, and undamaged. |
| 2. | Make sure that you are using the correct type |
|
| of fiber optic cable. |
| 3. | If you have autonegotiation enabled on the |
|
| local gigabit Ethernet interface, make sure |
|
| that it is enabled on the remote interface also. |
|
| If autonegotiation is disabled, it must be |
|
| disabled at the remote interface as well. |
| 4. | Replace the GBIC. |
|
|
|
Gigabit Ethernet card resets itself intermittently. | 1. | Issue the show diag command. If this |
|
| indicates a “parity error” occurred, contact |
|
| Cisco TAC for possible replacement of the |
|
| card. |
