When the adapter and cable is tested in wrap mode, the wrap is 
performed in the hub or concentrator, testing the adapter and 
all the cable between the adapter and the hub.
 
If you are using STP cable, you can disconnect the cable from 
the wall outlet and select Retest to exclude the wiring in the 
wall from the wrap test.

If your ring speed setting is different than the ring you are 
trying to insert into, this wrap test may pass, while insertion 
into the ring would fail.
