Loading images on the device
Any software upgrade or downgrade requires you to copy the downloaded images onto the device and load the new image on the device. You must load the boot code and flash code on the device.
Upgrade and downgrade software images
Software images for all Ruckus devices can be uploaded and downloaded between flash modules on the devices and a TFTP server on the network.
Ruckus 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.
You can use TFTP to copy an update image from a TFTP server onto a flash module. You can also use the Secure Copy Protocol (SCP) to copy images to and from a host. When you want to back up the current configuration and images for a device, you can copy the images and configuration files from a flash module to a TFTP server.
Loading the boot code
You can load the boot code using either TFTP or SCP as described in the following sections:
