LED Indicators

This chapter contains information about the operating features of the
Radiance 10/100 Mbps services line card.
The Radiance services line card provides several LEDs on the front
panel for the visible verification of unit status and proper functionality.
These LEDs can help with troubleshooting and overall network diagnosis
and management. There are separate receive (RX) and link (LK)
indicators for each port. The following table describes the meaning of
each LED when lit.
