AP Names & AP Groups No more B.F.N• AP Config:• AP’s now have a single GROUP• AP’s now have a single NAME• Both are alphanumeric text strings-

FQLN• Use Fully Qualified Location Name (FQLN) to associate APs and AMs to a location• FQLN Format:APname.Floor.Building.Campus• Used to map AP to

FQLN• NOTE: you do not have to use the FQLN mapper if you simply set the AP Name in the AP Installation menu to be the same as the AP Name in RF Plan

Power Level Adjustment• Aruba radio power levels are adjustable between 0 and 4• 4 is highest• Calibration will automatically set the power level t
