This section contains information about the operating features of the
Radiance 10Mbps single interface line cards.
LED Indicators
The Radiance 10Mbps single interface line cards provide several LEDs 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 activity (AT) and link (LK) indicators for each port.
When lit, the LEDs indicate the following information:
• PWR (power): normal operation.
• LK (link): satisfactory link status.
• AT (activity): receiving data.
• COL (collision): collision detected. (R111-12 only)
Once power is applied to the card, verify correct connectivity via the LK LED.
