G8264CS Application Guide for ENOS 8.4
You can insert a USB drive into the USB port on the G8264CS and use it to work
with switch image and configuration files. You can boot the switch using files
located on the USB drive, or copy files to and from the USB drive.
To safely remove the USB drive, first use the following command to un‐mount the
USB file system:
system usb-eject
Command mode: Global configuration
USB Boot allows you to boot the switch with a software image file, boot file, or
configuration file that resides on a USB drive inserted into the USB port. Use the
following command to enable or disable USB Boot:
[no] boot usbboot enable
Command mode: Global configuration
When enabled, when the switch is reset/reloaded, it checks the USB port. If a USB
drive is inserted into the port, the switch checks the root directory on the USB drive
for software and image files. If a valid file is present, the switch loads the file and
boots using the file.
Note: The following file types are supported: FAT32, NTFS (read‐only), EXT2, and
EXT3.
The following list describes the valid file names, and describes the switch behavior
when it recognizes them. The file names must be exactly as shown, or the switch
will not recognize them.
RSG8264_Boot.img

The switch replaces the current boot image with the new image, and boots with
the new image.
RSG8264_OS.img

The switch boots with the new software image. The existing images are not
affected.
RSG8264_replace1_OS.img
