4-2. Setting of PCS-1/1P and HUB
The initial setting of the PCS-1/1P is Auto.
In the Auto setting of the PCS-1/1P, 10/100 can be selected automatically, however, Half/Full cannot be selected
automatically. Therefore, if the HUB is set to Full mode, a connection failure or packet loss occurs. The following table
shows an example of connection between the PCS-1/1P and Catalyst 2950. When the HUB is set to 100FULL or 10FULL,
change the setting of HUB or adjust the PCS-1/1P setting to HUB. Refer to Operating Instructions.
