5.8  Power Up and Host Boot Mechanism 

The main power management function is performed by Power management IC (Atlas), 

which receives its voltage input from the PCIe interface. 3.3V on PCIe interface supplies 

power to PMIC. Atlas manages all data card power.  

  

When power is applied to the data card, the W3G ROM will attempt to enumerate with 

the host.  If the host if not ready, it will try again to enumerate with the host every 3 

seconds.  After successful enumeration, the host will download bootloader to the 

device.  After the download, the bootloader will re-enumerate as flash interface.  The 

firmware application is sent to the bootloader which downloads it to RAM and runs.  The 

firmware application will then enumerate with 2 ACM interfaces and 2 ECM interfaces. 

Description of the interfaces is provided in section 8.1.2
