Navigate to Maintenance --> System --> Change Personality
Upload the SA package 7.1RX
Please be sure you are on UAC 4.1R1 before attempting this action. There were some EGA MAG2600 units that were created with 4.1R0 as the default that cannot switch personalities. Once you have this uploaded, if you have one of these units, you can switch the personality using the "Switch Personality" option.
If the base image is 4.1R1, you can also change personality through the serial console.
