While classes represent large groupings of information, areas represent the information that
Fabric Watch monitors. For example, switch temperature, one of the values tracked by Fabric
Watch, is an area within the class Environment.
The tables in this section describe all of the areas monitored by Fabric Watch, organized by
their associated classes.

Area Description
Fan Refers to the speed of the fans inside the switch, in revolutions per
minute. It is important that the fans spin quickly enough to keep
the ambient temperature from rising to levels at which switch
damage might occur.
Power Supply Monitors whether power supplies within the switch are on, off,
present, or absent. Fabric Watch monitors power supplies to be
sure that power is always available to a switch.
Temperature Refers to the ambient temperature inside the switch, in degrees
Celsius. Temperature sensors monitor the switch in case the
temperature rises to levels at which damage to the switch might
occur.

occur when there is a conflict of domain IDs in a single fabric and the
principal switch has to assign another domain ID to a switch.
