Port LEDs
Each channel on the media converter has a series of LEDs that you can use to
monitor the status of the ports of the channel. Each twisted pair port has one
LED labelled T-LNK that indicates whether or not a link has been established
between the port and the node connected to the port. Each fiber optic port has
two LEDs, one labelled F-LNK that lights when a link has been established
with the node connected to the port and another LED labelled Active that
lights when the port is receiving traffic.
Link Test Switch
The Link Test switch is a fast and easy way for you to test the integrity of the
fiber optic connections to the fiber optic ports on the multichannel media
converter (see Figure 4). The AT-MCF6xx system has one Link Test switch
which is used to test all six fiber optic ports on the unit. The AT-MCF12xx has
two Link Test switches; one switch is used to test the fiber optic ports in
channels 1 through 6 and the second switch is used to test the fiber optic ports
in channels 7 through 12 on the unit.
Figure 4
Link Test Switch
The Link Test switch is used after installation to verify that the unit and
connections are operating properly, or whenever you need to test the fiber
optic ports or the integrity of the fiber connections to the nodes connected to
the ports.
The LED next to the Link Test switch indicates the operating mode of the
fiber optic ports. If the Test LED is lit amber, a link test is being performed on
the fiber optic ports associated with the switch. The section “Verifying the
Installation” on page 19 contains instructions for performing a link test.
