6.6 USB interface

The IG902 provides a USB 2.0 Host interface, which is mainly used for expanding storage devices.

IG902 supports USB storage device hot-plugging. It will mount all the partitions automatically.IG902 will mount all the USB storage device partitions under the path /mnt/usb/sda1, and only the first partition of the USB storage device will be mounted.

ATTENTION:

Before disconnecting the USB mass storage device, remember to enter the sync command to prevent data loss. When you disconnect the storage device, exit from the /mnt/usb/sda1 directory. If you remain in /mnt/usb/sda1, the automatic uninstall process will fail. If this happens, type umount /mnt/usb/sda1 to manually unmount the device!

6.7 Micro SD

The IG902 has a Micro SD card. The SD card does not support hot plugging and needs to be operated when the power is off. It will automatically mount all partitions

The IG902 will mount all partitions of the micro SD memory card to the /mnt/sd path. The naming format of the mounted folder is mmcblk0p<num>, where <num> is a number from 0 to 9

To install a Micro SD card, remove the protective case. Installing the Micro SD card into the IG902's SD card slot

6.8 SIM card slot

The IG902 is equipped with 2 drawer type SIM card slots for cellular communication, located on the upper panel. The installation procedure is as follows:

Step 1: The SIM card of IG902 needs to be installed in the case of power failure, please make sure that the device has been disconnected from the power supply before installation

Step 2: The protective casing needs to be removed before installation

Step 3: Insert the SIM card into the drawer SIM slot

6.9 Antenna Interface

IG902 has 4 antenna interfaces, and different models are equipped with different numbers of antennas. The antenna support for specific models can be found in the "Ordering Guide" section of the IG902 Series Edge Gateway datasheet.
