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.

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.

User Guide
This section contains information regarding the operating features of your
Radiance 10Mbps redundant interface line card.
LED Operation
Several LEDs are visible from the front panel. These include the switchover
(SW), power (PWR), secondary (SEC), link (LK) and activity (AT) LEDs. There
are separate link and activity LEDs for each of the three ports (MAIN,
PRIMARY and SECONDARY). Refer to the table below for a description of
each.
The indication of each LED is as follows:
LED Label Color (Status) Indication
SW Amber (steady) SECONDARY port was the active
port at some point. This LED
functions in Dynamic Recovery
Mode (DRM) only.
PWR Green (steady) Power ON
SEC Green (steady) SECONDARY port is active
OFF PRIMARY port is active
(MAIN) LK Green (steady) Receive link present
(MAIN) AT Green (blinking) Receiving data
(PRIMARY) LK Green (steady) Receive link present
(PRIMARY) AT Green (blinking) Receiving data
(SECONDARY) LK Green (steady) Receive link present
(SECONDARY) AT Green (blinking) Receiving data

Radiance 10Mbps Redundant Interface Line Card 17
Reset Push Button
A small RESET push button is located on the front panel of the Radiance
redundant interface line card. When used in conjunction with the card’s SW and
SECONDARY LEDs and theAUTO DIP switch setting, this push button allows
you to effectively maintain or troubleshoot a PRIMARY link connection.
Because of its small size and recessed placement within the front panel, press
the RESET push button with the tip of a pointed object. Pushing and holding the
RESET push button has no effect. It is the act of pressing the push button that
causes a reset.
In the event of a PRIMARY link failure, pressing the RESET push button has
the following effects:
If theAUTO switch is UP The active port automatically reverts to PRI-
and RED switch is UP MARY when primary link is reestablished and
pressing the RESET switch clears the SW LED.
If the AUTO switch is The active port does not automatically revert to
DOWN and the RED switch PRIMARY when a primary link is reestablished.
is UP Pressing the RESET switch clears the SW LED
and the SECONDARY LED and forces the
PRIMARY port to be the active port. If the
SECONDARY link is disabled, it reverts to the
PRIMARY if the PRIMARY has a good link.
If there is only a SECONDARY link, then the SW
and SECONDARY LEDs remain lit and pressing
the RESET switch has no effect.
If the RED switch is DOWN The card operates in Network Select Mode
(NSM). The RESET push button toggles the
active link between the PRIMARY and SECOND-
ARY ports. Note that the SW LED remains off
during Network Select Mode (NSM) operation.

18 User Guide
Link Loss Carry Forward (LLCF)
The Radiance 10Mbps redundant interface line card has been designed with
Link Loss Carry Forward ability for troubleshooting a remote connection. The
card is shipped with LLCF disabled.
When LLCF is enabled, the ports on the card do not transmit a link signal until they
receive a link signal from the opposite port. For example, if LLCF is enabled and
two redundant interface line cards are connected with nothing else connected to
them, the Link LED is not lit. When a valid link is established, a complete connec-
tion is accomplished.
The diagram below shows a typical network configuration using Radiance
redundant interface line cards for remote connectivity:
If the connection breaks, or the remote device fails, the card carries that link loss
all the way to the switch/hub which generates a trap to the management station.
The administrator can then look at the card to determine the source of the loss.

Radiance 10Mbps Redundant Interface Line Card 19
Switch On No Activity Received (SONAR)
The R712-11 is designed to protect a network from failure that would prevent
data from reaching its destination. With SONAR enabled, the card monitors the
active port for loss of data activity, as well as loss of a valid link. SONAR
enables the redundant line card to automatically change its active port to its
backup when the following two conditions occur:
•No data activity is detected on the active port for two (2) seconds.
• Data activity is detected on the backup port.
To switch active ports, the backup port must have data activity within the two-
second time-out period when the active port lost activity. If both ports have no
activity, the port that receives data activity first becomes the active port.
The active port is switched immediately if it loses its link and the backup port
has a link.
To properly activate SONAR, make sure that the following switches are en-
abled:
1. RED switch. This sets the redundant interface line card to operate in
Dynamic Recovery Mode.
2. LINK switch. This allows link signals to be sent out both ports.
3. SONAR switch.
The settings of the other DIP switches do not affect SONAR operation. How-
ever, SONAR will override the Auto Restore Primary Circuit (AUTO) switch. If
both SONAR and AUTO are enabled, the active port will not automatically
revert to the primary port (after switching to the secondary port) if the primary
port has link but no activity. Data activity on the primary port must also be
detected during the two-second time-out period before the active port reverts
back to the primary port.
NOTE: The R712-11 is shipped with SONAR disabled. In addition to the
hardware switch setting, SONAR can be enabled via console commands or
through WebBeacon or NetBeacon management software (version 2.0 or later).
Refer to the Radiance Command Line Interface Reference Guide,
NetBeacon Element Management Software Installation & User Guide or
WebBeacon Software Installation & User Guide for software instructions.
