Section I: Features
CDC and FDC
Duplex Mode and
Collision LEDs
The CDC and FDC LEDs are used to view the duplex modes of the ports
in a channel and, for ports operating in half-duplex mode, the collisions.
The CDC (Copper, Duplex mode, Collisions) LED reports this information
for the twisted pair port and the FDC (Fiber optic, Duplex mode, Collisions)
LED displays the same information for the fiber optic port.
These LEDs can display only one channel at a time and have to be used
with the Mode button. For example, if you were to use the Mode button to
select channel 4, the CDC and FDC LEDs would report the duplex modes
and the collisions for twisted pair port 4 and fiber optic port 4. For more
information, refer to “Mode Button” on page 51.
Twisted Pair
Port
Off
The fiber optic port in the channel
can establish a link with its network
device, but the twisted pair port is
unable to establish a link with its
local device.

or Amber
Both ports in the channel can
establish links to their network
devices, but one of the ports is
connected to another media
converter that also supports the
Smart MissingLink feature, forming
a chain of converters. A link has
been lost on one of the ports in the
chain, causing a ripple affect
through the chain of converters.
Alternatively, one of the ports is
only able to form an intermittent
link with its network device.
