Firmware download from a USB device

The Brocade 300, 5100, 5300, 7800, 8000, and VA-40FC switches and the Brocade DCX and
DCX-4S Backbones support a firmware download from a Brocade branded USB device attached to
the switch or active CP. Before the USB device can be accessed by the firmwareDownload
command, it must be enabled and mounted as a file system. The firmware images to be
downloaded must be stored under the relative path from /usb/usbstorage/brocade/firmware or
use the absolute path in the USB file system. Multiple images can be stored under this directory.
There is a firmwarekey directory where the public key signed firmware is stored.
When the firmwareDownload command line option, -U (upper case), is specified, the
firmwareDownload command downloads the specified firmware image from the USB device. When
specifying a path to a firmware image in the USB device, you can only specify the relative path to
/firmware or the absolute path.

Enabling USB

1. Log in to the switch using an account assigned to the admin role.
2. Enter the usbStorage -e command.
