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.

Radiance 10Mbps Redundant Interface Line Card 5
The Radiance 10Mbps redundant interface line card provides the following
features:•Dynamic Recovery Mode (DRM) operation to ensure session
integrity and increased uptime.
•Network Select Mode (NSM) operation to redirect and isolate
traffic adding extra security.
•Immediate switching from the primary link to the secondary link if
the primary link fails.
•In addition to switching on loss of link, the R712-11 can be
configured to switch on loss of data (SONAR).
•Minimal impact on the round trip delay for communication in
half-duplex collision domains.
•Twisted-pair ports equipped with MDI-II to MDI-X switches to
eliminate the need for crossover cables.
* Refer to the page titled Link Loss Carry Forward (LLCF) in the User Guide section of this document for
additional information.

6 Overview
•Can be configured to return automatically to the primary link after
the failure condition is resolved or only upon secondary failure, or
manually switched back to primary after failover.
•Full- and half-duplex support.
•Auto-polarity support on all twisted-pair ports.
•In addition to providing link and data on the active ports, the
Radiance redundant interface line card can be configured to
provide link or link-and-redundant-transmit-data on the inactive
port.
•Link Loss Carry Forward*enable/disable switch.
•Compatibility with devices configured for auto-negotiation.
•Fast failover time (400 ms) ensures low packet loss.
•Fused power on the card to protect the system from a short circuit.
This prevents a faulty card from bringing down an entire system.
•Full compliance with applicable sections of IEEE 802.3/802.3u.
•Transparent to data frame sizes.

* DIP switches can also be managed via console commands or through Metrobility’s NetBeacon or
WebBeacon management software. Refer to the
Radiance Command Line Interface Reference
Guide
,
NetBeacon Element Management Software Installation & User Guide
or
WebBeacon
Management Software Installation & User Guide
for software management information.
Follow the simple steps outlined in this section of the manual to install and
start using your Radiance 10Mbps redundant interface line card.
NOTE: Electrostatic discharge precautions should be taken when handling any
line card. Proper grounding is recommended (i.e., wear a wrist strap).
Unpack the Line Card
Your order has been provided with the safest possible packaging, but
shipping damage does occasionally occur. Inspect your order carefully
for damage that may have occurred during shipment. If you discover
any shipping damage, notify the carrier and follow their instructions for
damage and claims. Save the original shipping carton if return or storage
of the unit is necessary.
Set the DIP Switches
A set of DIP switches, located on the line card, provides user-selectable
configuration options for several modes of operation. These switches
are clearly marked on the printed circuit board. Refer to the table on the
following pages for the proper setting of the DIP switches.*
8 Installation Guide
R711-11: The DIP switches for this card can be set for the following
operational functions:
Switch Name Position* Operation
TX UP Transmits data on both the PRIMARY and
SECONDARY ports simultaneously. The LINK
switch must be enabled on both ports.
DOWN Transmits data on the active port only.
(default)
AUTO UP Automatically reverts the active port back to the
PRIMARY port when the primary link is
reestablished.
DOWN Does not revert the active port back to the
(default) PRIMARY port when the primary link is reestab-
lished until the SECONDARY link fails. If the
SECONDARY link does not fail, the SECOND-
ARY port remains active. Use the RESET push
button located on the front of the card to force the
active port back to the PRIMARY port and to clear
the switchover (SW) LED.
LINK UP Link signals are sent out on both the PRIMARY
and SECONDARY ports (i.e., link is sent out
both ports).
DOWN Link signals are sent out on the active port
(default) only. With the LINK switch in this position, data
is not transmitted out the inactive port regardless
of the TX switch setting.
LLCF UP Link Loss Carry Forward is enabled.
DOWN Link Loss Carry Forward is disabled.
(default)
* When setting DIP switches, the UP position is when the lever of the switch is pushed away from the
circuit board. The DOWN position is when the lever of the switch is pushed toward the board.

Switch Name Position Operation
UP Operates in Dynamic Recovery Mode (DRM).
(default) If the primary link fails, the SECONDARY port
becomes active. Refer to the description for the
AUTO switch.
RED DOWN Operates in Network Select Mode (NSM). Use
the RESET push button to toggle between
PRIMARY and SECONDARY. In NSM, the
AUTO switch sets the initial active port on
power-up. Note that the SW LED remains off in
NSM.

10 Installation Guide
R712-11: The table below describes the operational functions of the
DIP switches on the R712-11 line card with SONAR.
Switch Name Position* Operation
SONR UP SONAR is enabled. To properly activate
SONAR, the RED and LINK switches also must
be enabled.
DOWN SONAR is disabled.
(default)
TX UP Transmits data on both the PRIMARY and
SECONDARY ports simultaneously. The LINK
switch must be enabled on both ports.
DOWN Transmits data on the active port only.
(default)
AUTO UP In Network Select Mode (NSM), sets the default
port to SECONDARY.
In Dynamic Recovery Mode (DRM), the active
port automatically reverts back to the PRIMARY
port when the primary link is reestablished. If
SONAR is enabled, activity detection is also
required before the active port reverts back to
PRIMARY.
DOWN In NSM, sets the default port to PRIMARY.
(default) In DRM, the active port does not revert back to
the PRIMARY port when the primary link is
reestablished or if activity is detected (SONAR
enabled). Use the RESET push button located on
the front panel to force the active port back to
PRIMARY and to clear the switchover (SW) LED.
Note: The active port reverts back to PRIMARY
if the SECONDARY port has no link or a loss of
activity for two (2) seconds (SONAR enabled)
and the PRIMARY port has a valid link and data.
* When setting DIP switches, the UP position is when the lever of the switch is pushed away from
the circuit board. The DOWN position is when the lever of the switch is pushed toward the board.
