I recommend that you check that the interface is UP using 'show interface FastEthernet0/1'.  If it is not up, you will not be able to ping the IP address that you have assigned to the interface.

If there is no active connection on the interface - so it shows as down when you issue show ip interface brief, it will not ping.

You can use the no keepalive command on the interface if you want to force the interface up without attaching a cable.
