Recovering from a Mandatory Stop
Pushing the RST button (see page 49) 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 49) 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.
