Known Issues:

- If your configuration has ALL three of the characteristics listed:

 1. You have inband management disabled
 2. You have a management VLAN enabled
 3. You manage a remote radio (far side of an airFiber RF link) by connecting the remote data port to the management port either directly or through a switched network

you will need to enable inband management on the remote radio BEFORE you upgrade. After the upgrade, you can then reconnect to the remote radio and disable inband management. Failure to do so will leave the remote radio unmanageable over the RF link (local access via the management port will still function normally).

- Only first 8 characters of old passwords are used after update - must reconfigure for longer passwords
