Overview
The Radiance 10Mbps redundant interface line card offers the resiliency of
data link redundancy to ensure network integrity with no down time. This link
duplication provides the nonstop networking capability essential for high
priority traffic and mission-critical applications. The Radiance 10Mbps redun-
dant interface line card provides full redundant data paths for Ethernet devices.
The card actively monitors the primary link and, if it fails, automatically
activates the secondary link without interruption to network operation.
The R712-11 also features a function called Switch On No Activity Received
(SONAR ). With SONAR enabled, the line card provides protection against loss
of data activity as well as link integrity.
Management control over the Radiance redundant interface line card allows the
network administrator to monitor and configure the card via a PC using console
commands, our NetBeacon
™
or WebBeacon
™
management software, or any
SNMP application.
The Radiance 10Mbps redundant interface line card contains a MAIN port, a
PRIMARY port and a SECONDARY port. Redundancy is provided between the
PRIMARY and SECONDARY ports.
