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.
