Chapter 1 Product Overview
Services Modules
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.
