System Startup and Shutdown
The system administrator can start, configure, restart, and stop the system. System startup includes cold
start and warm start.
Cold Starting the System
Cold start the system from the power-off state. Complete the following steps to cold start the system:
1. Apply power to all field stations. When stations are powered they are operational although they do
not communicate with the card rack until the cold start completes.
2. Apply power to the card rack. The visual indicators on the MCU card illuminate. The O NLINE
indicators on the PPI card illuminates when the system is running.
Warm Starting the System
Warm start the system from the power-on state by pressing the R ESET button on the MCU bezel in the
card rack. Field stations remain operational during the warm start.
System Shutdown
The system is shutdown by removing power from the card rack. Field stations continue limited operation
until their power is removed.
