52 Section I: Features
Channel selection on the AT-MCF2032SP Module is indicated with the
row of numbered LEDs beneath the SFP slots.
Figure 23. Channel LEDs on the AT-MCF2032SP Module
You can select only one channel at a time. After you’ve selected a
channel, the CDC and FDC LEDs reflect the duplex mode settings and the
collisions of the channel’s two ports.
To set the operating mode of a channel, press the middle of the button to
toggle the channel between Link Test (LT), MissingLink (ML), and Smart
MissingLink (SML) modes. The operating mode of a channel is reflected
by the LT, ML, and SML LEDs. A change to the operating mode is
immediately activated on a channel.
Here is an example on how to use the Mode button. Let’s assume that you
wanted to determine the duplex modes of the two ports in channel 8 (i.e.,
twisted pair port 8 and fiber optic port 8) and to change the operating
mode of the channel to the Link Test mode. You first select channel 8 by
turning the Mode button up or down to toggle the channel LEDs until the
CH8 LED under fiber optic port 8 or, in the case of the AT-MCF2032SP
Module, the 8 LED is on. At that point the CDC and FDC LEDs reflect the
duplex modes and collisions of the two ports of channel 8. To change the
operating mode of the channel to the Link Test mode, you press the button
to toggle the operating mode LEDs until the LT LED is on.
Note
Using the Mode button to view the CDC and FDC LEDs or to change
the operating modes of the channels on a module does not affect
the operations of the channels.
