Controller Based WLANs

This article applies for all 70xx/720x controller running 6.3/6/4 version and upgrading of controller is through CPBoot using USB

Controller will look for a particular folder (Arubaimage) in USB for code upgrade. Hence create a folder called "Arubaimage" in USB and copy AOS image into that folder

After we insert the USB to the controller we can use the below commands to verify the connection

(Aruba7205) #show usb

Now reload the controller and get into the CPBoot.
 
(Aruba7205) #reload

cpboot>upgrade [device: partition] [usb device:partition] <filename of the image> <------ this is the general format of upgrade command.

Below is an example
            
cpboot>upgrade 0:0 1:1 Arubaimage/ArubaOS_72xx_6.4.4.4_53338  

AOS Upgrades with Ancillary Files images from cpboot will cause <--------- (executing the command will upgrade both the partition 0 and 1 to the corresponding version)
partition 0 and 1 to both contain the new AOS version.

Note:

All the models of 70xx and 72xx has only USB port either in the front or rear panel. But 7205 controller has two USB ports one in front and another one in rear end. We recommend to use rear end panel of the 7205 controller for USB code upgrade.
