The front panel of the 9920-16C modules contains four LEDs located between the upper and lower ports. The two LEDs on the left are both green and indicate the channel within the port, which is indicated by the remaining two LEDs. The font panel also contains a Channel Selector button, which cycles through the four selectable channels. The selected channel applies to all ports on the card.

The rate indication determines if a port is channelized. The link status for the entire port is indicated regardless of the channel selected when the port is not channelized.
The rate/link/activity LEDs use the colors red, green, and blue and indicate the configured port rate, port linkage, and port traffic activity. The LEDs also indicate fault conditions.
