You can shutdown the telephone system for a specified number of minutes.
The telephone system remains unavailable for the duration you specify, the default 10 minutes. After the shutdown duration, there is a further short delay for the telephone system to complete its restart.
Important:
A shutdown must always be used to switch off the system. Simply removing the power cord or switching off the power input may cause errors.
This is not a polite shutdown, any users calls and services in operation are stopped. Once shutdown, the system cannot be used to make or receive any calls until restarted.
The shutdown process takes up to a minute to complete. When shutdown, the CPU LED and the base card LEDs 1 and 9 (if trunk daughter card fitted) flash red rapidly. The memory card LEDs are extinguished. Do not remove power from the system or remove any of the memory cards until the system is in this state.
To restart a system when shutdown indefinitely, or to restart a system before the timed restart, switch power to the system off and on again.
