ONIE self-update
WARNING:
Do not power-cycle the board when an ONIE self-update is in progress. If the install or upgrade task
is interrupted, the board might have an invalid MBR/GPT/Grub, and would not boot into ONIE. In this case, use
a recovery procedure to bring up the switch so long as the BIOS is functional.
I2C bus
NOTE:
After a thermal shutdown, the I2C bus could lock up occasionally. If this action happens, you must manually power
cycle the switch.
