Converter Modules
This procedure explains how to verify the operations of the individual
channels on a media converter module, using the Link Test mode and the
Link LEDs. The procedure assumes the following:
❒
The media converter chassis is powered on.
❒
The network cables are connected to the ports on the media converter
module and to the local and remote network devices.
❒
The local and remote network devices are powered on.
To verify the operations of a channel on the media converter module:
1. Turn the Mode button up or down to select a channel, as explained in
“Mode Button” on page 51.
2. Set the channel to the Link Test operating mode by pressing the
middle of the Mode button until the LT LED is on.
3. Observe the Link LEDs of the twisted pair and fiber optic ports of the
channel.
❒
If the Link LEDs for both of the ports in the channel are on, the
ports have established links with the local and remote network
devices, which may already be forwarding network traffic to each
other through the media converter channel. You can either leave
the channel in the Link Test mode or, by pressing the middle of the
Mode button, change it to the MissingLink or Smart MissingLink
mode, indicated by the ML and SML LEDs, respectively. For
further information on the operating modes, refer to “Channel
Operating Modes” on page 37.
❒
If the Link LED for a port in the channel is off, the port does not
have a link to the network device. For suggestions on how to
resolve the problem, go to “AT-MCF2012LC, AT-MCF2012LC/1
and AT-MCF2032SP Media Converter Modules” on page 146 in
Chapter 23, “Troubleshooting the Modules”.
4. Repeat this procedure to test the other channels.
