If a single component or a set of components on the switching module fails, this failure will not disable another switching module if that is the only failure in the system.
For the detection of most component failures, each switching module has a hardware watchdog timer that resets the card if is not serviced periodically.

|
|
|
|
|
| Orange | One of the following occurs or occurred: |
|
|
| • The module is booting or running diagnostics (normal |
|
|
| initialization sequence). |
|
|
| • The inlet air temperature of the system exceeded the |
|
|
| maximum system operating temperature limit (a minor |
|
|
| environmental warning). To assure maximum product life, |
|
|
| you should immediately correct the environmental |
|
|
| temperature and restore the system to normal operation. |
|
|
|
|
|
| Red | One of the following occurred: |
|
|
| • The diagnostic test failed. The module is not operational |
|
|
| because a fault occurred during the initialization sequence. |
|
|
| • The inlet air temperature of the system exceeded the safe |
|
|
| operating temperature limits of the card (a major |
|
|
| environmental warning). The card shut down to prevent |
|
|
| permanent damage. |
