Firmware update
To update the rmware from a remote machine, use the BMC LAN interface.
You can also update the rmware in the local host OS using the USB interface. The USB interface is between the BMC and the
microprocessor. When using the USB, the BMC simulates a virtual USB device, then Yafuash sends the image to the BMC via the USB
bus. Typically the update process completes in ve minutes.
For more information about Yafuash, see the S5200-ON Series Release Notes.
