User Guide
This section contains information regarding the operating features of the
Radiance chassis stacking line card.
LED Indicators
The Radiance chassis stacking line card provides several LEDs for the visible
verification of unit status and proper functionality. These LEDs can assist in
troubleshooting and with overall network diagnosis and management. There are
separate link/speed and activity/duplex indicators for each port.
After power is applied to the card, verify correct connectivity via the LK LEDs.

Full-Duplex Flow Control (FDFL)
Full-duplex flow control is provided as a means of avoiding packet loss during
times of network congestion. With FDFL enabled (default), the Radiance line
card issues a PAUSE frame when there is no buffer space available for incoming
packets. FDFL is configurable through management software
*
only.
When FDFL is enabled, it is set on all four ports. However, FDFL is applicable
only to a port when the following conditions are met:
• The chassis stacking line card is in full-duplex mode.
• Auto-negotiation is enabled on the port.
• During auto-negotiation, the port’s link partner indicated that it supports
PAUSE frames.
*Refer to the
Command Line Interface Reference Guide, NetBeacon Element Management Software Installation & User’s
Guide
or
WebBeacon Management Software Installation & User’s Guide
for software management information.
