 3.Umount the disk with "umount [disk location]" (e.g., /dev/sdc)

root@jeff-D520MT-K:~# umount /dev/sdc2

 4. Start burning the ISO with "sudo dd if=[.ISO file location] of=[disk location]" command.

STEP2. Insert the USB drive to the data center switch. (e.g., AS6712-32X)

STEP3. Plug in the console cable into the console port. (e.g., AS6712-32x)

STEP4. Open the terminal. (e.g., Teraterm)

Note:  Please set the baud rate as 115200

STEP5. Power on the data center switch, wait for a few seconds and press "ESC" to enter the BIOS setup.

STEP6. Go to the Boot section and select the USB drive as boot option #1. (e.g., I-O DATAUSB FLASH DRIVE)

STEP7. Go to Save&Exit section, select "Save changes and Reset"

STEP8. Wait for the reset time and the ONIE Installer screen will pop up, select "ONIE: Embed ONIE", the system will start to reinstall the ONIE.

STEP9. When showing the "Installing ONIE on:/dev/sdx", the installer is almost complete. (e.g., /dev/sdb)

STEP10. The system will reboot after completion.

STEP11. Please follow STEP5 to go into BIOS again.

STEP11. Go to the Boot section and select the FLASH drive as boot option #1. (e.g., ATP ATP IG eUSB 1100), now you can remove the USB drive.

Note. Edgecore switch has two kinds of storage drives, eUSB or mSATA. Therefore, your switch's  FLASH model name might be different from the following picture.

STEP12. Go to "Save & Exit" section, select "Save changes and Reset"

STEP13. ONIE is recovered.
