Upgrade Procedure

2. In order to provide the most stable wireless conditions possible during the upgrade process it is recommended to 
set the radio speed to the minimum (6 Mbps) in both the MU and RU. Turn autorateshifting off during the 
upgrade. 
3. Turn on the radio’s tftp daemon 
4. From computer’s command prompt, tftp the firmware file into the radio using binary mode. 
5. After file is successfully tftp’d to the radio, the radio will automatically reboot itself and load the new firmware 
 
IMPORTANT: DO NOT POWER CYCLE OR INTERUPT THE REBOOT PROCESS IN ANY MANNER. 
WAIT AT LEAST THREE MINUTES TO ENSURE AUTOMATIC REBOOT COMPLETION. LOSS OF 
POWER DURING THE REBOOT SEQUENCE WILL RESULT IN A CORRUPTED/INCOMPLETE 
FIRMWARE LOAD WHICH WILL REQUIRE REFLASHING AT THE FACTORY. 
6. Repeat process for other radio 
7. Repeat process for web file.
