		MANDATORY STOP
		Pushing the RST button (See The RST Button, p. 55) causes the island
		bus to reconfigure itself with factory-default operating parameters,
		which do not support mandatory I/O status.
		￿Do not attempt to restart the island by pushing the RST button.
		If a module is unhealthy, replace it with the same module type.
		Failure to follow this precaution can result in death, serious injury,

Hot Swapping a	If the NIM has stopped island bus operations because it cannot detect a healthy
Mandatory	mandatory module, you can recover island bus operations by installing a healthy
Module	module of the same type. The NIM automatically configures the replacement module
	to match the removed module. Assuming that other modules and devices on the
	island bus are correctly configured and conform to their configuration data as written
	to Flash memory, the NIM will start/restart normal island bus operations.
	Note: When hot swapping a mandatory module with a Fipio NIM present, the
	hardware configuration fault bit (x5) in the standard channel status is set.
	Replacing the module does not clear the bit. To restore normal operations in
	accordance with Fipio standards, reset the NIM with a reset command from the
	fieldbus or cycle NIM power.
