Understanding the Front Panel Display LEDs
The front panel displays LEDs as they appear on the device front panel. The LEDs are color-coded with
the same configuration as the front panel.
Each card has its own set of LEDs. The LEDs on the host card indicate the device LED indication mode.
The LEDs on the other cards indicate the card individual port status.
Front Panel Display Mode LEDs
On the Host card are eight mode LEDs. Each LED represents a device function mode. The mode
selection determines what function is indicated by the LEDs on the individual cards. The selection is
made by physically clicking the Mode Selector button. The mode selected is applied to all the LEDs on
the device, for example, if "Rx" is selected, wherever a port is receiving a signal, the port corresponding
LED indicates this status.
Device Front Panel Display Power LEDs
On the Host front panel there are two power supply LEDs. The LED indicates the device power supply
status.
The top LED indicates if the device is powered by the power supply 1. The bottom LED indicates that
the unit is power by the power supply 2. The following table describes the color code representing the
power supply status.
