AP 2.2 validation tests were performed on SunFDDI (revision 6.0) and GigabitEthernet (revision 2.0). If you install either of these devices, you must use the revision level that was tested, unless a higher revision level exists. In addition, you must install all of the available patches for these devices. Refer to http://www.sunsolve.sun.com for more information about the patches.
