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.
