The system should always be shutdown using the following process before it is switched off. This ensure that system actions such a file writes are completed before the power is removed. It also ensure that the current configuration in the system's memory is backed up to its System SD card.
The shut down can be either indefinite or for a set period of time after which the system will automatically reboot. This command performs a indefinite system shutdown. To restart the system power will need to be removed and then reapplied. To performed a timed shutdown refer to Shutting Down the System.
! WARNINGS
•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 calls and services in operation will be stopped. Once shutdown, the system cannot be used to make or receive calls until restarted.
•The shutdown process takes up to a minute to complete. When shutdown, the CPU LED and the IP500 base card LEDs 1 and 9 (if trunk daughter card fitted) will flash red rapidly. The memory card LEDs on the rear of the control unit are extinguished. Do not remove power from the system or remove any of the memory cards until the system is in the 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.
