USB Port
USB device can be inserted for auto firmware up-gradation. Switch auto-checks the firmware
version present in the USB device and upgrades if newer version of Firmware is present.
For example if you are running with Firmware version 1.0.0.S0 you need to upgrade the
firmware to version 1.0.1.S0 then you need to follow these steps.
1.
Create a folder with model name in USB (eg: NGI-M08C4-L2)
Note: don’t add ‘A’ in folder name.
2.
Insert new firmware file in that folder.
Note:
There should be only one firmware file in the folder. If there is more than one, the
firmware upgrade process will stop.
3.
