Note Software downloads are only necessary when a revision of the code is needed.
The supervisor module can force a reset on the services module and controls whether power is applied to the switching module.
If a single component or a set of components on the switching module fails, this failure does not disable another switching module if that is the only failure in the system.
Each ASM has a hardware watchdog timer to detect most component failures. The watchdog timer resets the card if it is not serviced periodically.
LEDs on the Fibre Channel Advanced Services Modules
Table 1-18 describes the LEDs for the ASM.

|
| Status |
| Green | All diagnostics pass and the module is operational (normal | |||
|
|
|
|
| initialization sequence). | |||
|
|
|
|
|
| |||
|
|
|
| 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 ensure 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. | |||
