CAUTION
	•	The SD Memory Card must be inserted in the SD Memory Card slot of the IPCMPR card before startup.
	•	Before touching the System Initialize Switch, discharge static electricity by touching ground or wearing a grounding strap.
	•	Once you have started the PBX and if you unplug the PBX, do not perform the following procedures to start the PBX again. Otherwise, your programmed data is cleared. To restart the PBX, refer to "5.1.4 Using the Reset Button".
	•	The PBX will continue to be powered even if the power switch is turned "OFF".
	•	The power supply cord is used as the main disconnect device. Ensure that the AC outlet is located near the equipment and is easily accessible.

System Initialization Procedure

1.

Slide the System Initialize Switch to the "SYSTEM INITIALIZE" position.

2.

Plug the AC power cord into the PBX and an AC outlet, and turn on the PBX. The RUN indicator will flash.

Note
	For safety reasons, do not stretch, bend, or pinch the AC power cord.

3.

While the RUN indicator is flashing, slide the System Initialize Switch back to the "NORMAL" position. Depending on the configuration, initialization takes about 1 min to 3 min. If successfully executed, the RUN indicator will stop flashing and stay lit.

All data will be cleared, and the PBX as well as all optional service cards (except for the IP-GW card) will be initialized to the default values. The DPTs should show the time as 01:00.
The data of the IP-GW card will not be initialized.

Note
	Use only the AC power cord included with the PSU.
