Firmware update

BMC, BIOS, and CPLD firmware update is required before you install the Z9264F-ON switch.

CAUTION: The preferred method of updating the BMC code is through the ONIE Firmware Updater. For

firmware update instructions, see the

Dell EMC PowerSwitch Firmware Updater Release Notes

. Only use the

following update method if there is an issue with the Firmware Updater.

To update the firmware from a remote machine, use the BMC LAN interface.

You can also update the firmware in the local host operating system 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 using the USB bus. Typically the update process completes in five minutes.

For more information about Yafuflash, see the Dell EMC PowerSwitch Z9264F-ON Release Notes.
