5 Firmware update To update the firmware from a remote machine, use the BMC LAN interface. You can also update the firmware 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 Yafuflash sends the image to the BMC via the USB bus. Typically the update process completes in five minutes. For more information about Yafuflash, see the S5200-ON Series Release Notes. Table 5.
