Services Modules
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.

Description
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.
•
T
he 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.
