Recovering from a Mandatory Stop

Pushing the RST button (see page 53) while recovering from a mandatory stop

loads the island’s default configuration data.

Hot Swapping a Mandatory Module

If the NIM has stopped island bus operations because it cannot detect a healthy

mandatory module, you can recover island bus operations by installing a healthy

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 starts of restarts normal island bus operations.

WARNING

UNINTENDED EQUIPMENT OPERATION/LOSS OF CONFIGURATION—RST

BUTTON WHILE RECOVERING FROM MANDATORY STOP

Pushing the RST button (see page 53) causes the island bus to reconfigure itself

with factory-default operating parameters, which do not support mandatory I/O

status.

z Do not attempt to restart the island by pushing the RST button.

z If a module is unhealthy, replace it with the same module type.

Failure to follow these instructions can result in death, serious injury, or

equipment damage.
