+== Modem Power On sequence
+'''The CMB100 will not power on by default by design without toggling a the pOnOff pin'''
+
+To turn on the CMB100 the pOnOff input on connector pin 19 must be pulled high for at least 6 seconds then released.
+
+The pOnOff pin is connected to the M.2 B-Key pin 8 W_DISABLE1# signal though an inverter. Because this signal is an active-low wireless disable it is usually driven high by default by the board/firmware on Gateworks boards so you need to drive it low for 6 seconds then high to get the CMB100 to power on.
+
+To power off the CMB100 gracefully drive W_DISABLE1# signal high for at least 3 seconds.
+
+To unconditionally shut down the CMB100 drive FULL_CARD_POWER_OFF# low.
+
+The following table shows the GPIO mapping for these two signals on various Gateworks products with an M.2 B-Key sockets:

+saveenv

+== Modem Mode 
 
 The modem can be configured to be in different USB modes. Consult the AT command guide for all the modes.
