4.2 Turning OFF the GE865
The turning off of the device can be done in three ways:
• by software command (see GE865 Software User Guide)
• by hardware shutdown
• by Hardware Unconditional Restart
When the device is shut down by software command or by hardware shutdown, it issues to the
network a detach request that informs the network that the device will not be reachable any more.
4.2.1 Hardware shutdown
To turn OFF the GE865 the pad ON# must be tied low for at least 2 seconds and then released.
The same circuitry and timing for the power on shall be used.
The device shuts down after the release of the ON# pad.
TIP: To check if the device has powered off, the hardware line PWRMON should be monitored. When PWRMON goes
low, the device has powered off.
