X330W-2DS1 Front Panel and LEDs
The front panel of the X330W-2DS1 has two columns of four LEDs each, one for 
each Serial (WAN) port in the access router module. There is also a Fast Ethernet 
port, and a Console port for directly connecting a terminal. Between the LEDs and 
the Console port there is a RST/FIV button for manually resetting the module.
