|
|
LED | Status | Description |
|
|
|
Self Test | ON | The module is being self tested as a result of being powered on or because of a reset. If it |
|
| stays ON for a prolonged period of time (more than 30 seconds), the module has experienced |
|
| a hardware failure. See the instructions for the ON condition under the Fault LED below. |
|
|
|
| Flashing | This should only occur if the Fault LED is also flashing, and indicates that the module has failed |
|
| its firmware self test. See the instructions for the Flashing condition under the Fault LED below. |
|
| Try resetting the switch and module by pressing the Reset button on the module. |
|
| If the fault condition persists, attach a PC to the switch and run the console interface; the log |
|
| file should indicate the error condition. See Note below. |

|
Fault | ON | The module is being self tested as a result of being powered on or because of a reset. If it |
|
| stays ON for a prolonged period of time (more than 30 seconds), the module has experienced |
|
| a hardware failure. |
|
| Try resetting the switch and module by pressing the Reset button on the module. |
|
| If the failure persists, it may be due to incorrect module installation. Remove power from the |
|
| switch and try reinstalling the module. This condition may also be caused by an incorrectly |
|
| installed SIMM on the module. While the module is removed, verify that the SIMM is correctly |
|
| installed. |
|
| Apply power to the switch again. If the fault condition persists, the module may have to be |
|
| replaced. |
|
| If none of these procedures resolves the condition, the module may be faulty and would need |
|
| to be replaced. Contact your |
