Upgrade Process

Software images for all RUCKUS ICX devices can be uploaded and downloaded between flash modules on the device and a TFTP, SCP, HTTPS, or USB module on the network.

RUCKUS ICX devices have two flash memory modules:

• Primary flash: The default local storage device for image files and configuration files.
• Secondary flash: A second flash storage device. You can use secondary flash to store redundant images for additional booting reliability or to preserve one software image while testing another one.

Only one flash device is active at a time. By default, the primary image becomes active when you reboot the device.

The following methods are available to upgrade your RUCKUS ICX device.

• Trivial File Transfer Protocol (TFTP): Use TFTP to copy an image from a TFTP server onto a flash module.
• Secure Copy Protocol (SCP): Use SCP to copy images to and from a host (recommended).
• Hypertext Transfer Protocol Secure ( HTTPS): From FastIron release 08.0.80, you can use HTTPS, which requires a server that supports HTTP over TLS.
• Universal Serial Bus (USB): From FastIron release 08.0.30, you can use a USB device that contains the appropriate files and is connected to a standalone unit or the active controller in a stack.
  Note: The USB storage format must be FAT32. The USB drive can be formatted from a host computer or from an ICX device. Copying the firmware or configuration files from a host computer to USB is straightforward, like copying any other file from a computer to USB.
