In addition to the connectors previously described in the Interconnection section the
front panel includes the following indicators and controls:
Each of the two electrical ports has an associated green LED that lights up when the link
operates at 1Gbit/s, stays off for other datarates and a yellow LED that both lights up to
indicate that the link has been established and blinks when there is activity. The optical
port has a single associated yellow LED that lights up when the link has been
established.
The REF. LED lights up in green when the presence of a 10MHz signal is detected on the
rear bus. Otherwise this LED lights up in red.
