Download Software from a USB 3.0 Device

Extreme devices support software (firmware) download from a USB 3.0 device. Before you can access the USB device, you must enable the device and mount it as a file system. The software images to be downloaded must be stored in the /brocade/firmware directory. Multiple images can be stored under this directory.

Note

For software download, USB 3.0 used can be in VFAT or EXT4 format. As a best practice, use USB devices with more than 16GB of storage.

Ensure that the USB device is connected to the device.

Enable the USB device from Privileged EXEC mode.
