Overview  
The Metrobility Radiance 100Mbps Access Line Cards are the industry’s  
first media converters with the ability to reach across a wide area network  
(WAN) to communicate, test and reconfigure an unmanaged remote device,  
without reducing the available bandwidth to the customer site. This capability is  
accomplished through the employment of Metrobility’s revolutionary Radiance  
technology. Using this protocol, the line cards are able to receive and transmit  
special management packets in an embedded side channel that exists between  
data packets.  
Radiance access line cards continually exchange information in a master/slave  
relationship through the fiber optic port. A card can serve as both a master and a  
slave. While the master card must be under local software control via an SNMP  
agent such as Metrobility’s NetBeacon® or WebBeacon management software, the  
slave card can be located up to 100 km away.  
Through NetBeacon, the network administrator can open a dialog with the remote  
device to reset its hardware switch settings, monitor its environmental parameters,  
or view port details and statistics. NetBeacon provides extensive real-time and  
historical graphs to display information such as the packet error rate and packet  
details. The administrator can also conduct tests on the remote link, without any  
bandwidth reduction, and isolate problems to prevent downtime. This end-to-end  
visibility and testing of the network simplifies network management and increases  
reliability.  
The Radiance access line card offers several operational functions that are set by  
the user through hardware switches, software commands or remote management  
instructions. Among the features unique to the card are loopback mode, bandwidth  
provisioning with adjustable burst size setting, Far End Fault (FEF), and write  
protection. Loopback enables a port to return its incoming data back to the sender.  
Bandwidth provisioning and maximum burst size setting allow the user to set the  
receive (RX) and transmit (TX) bandwidth through the copper port. FEF enables a  
locally managed line card to detect a break in the remote card’s fiber port receiver.  
Write protection enables or disables the remote card from controlling the locally  
managed card. The combination of these functions, along with the line card’s  
remote management ability, enable easy deployment of Ethernet WAN services to  
customers.  
For updating or expanding an existing network, Metrobility offers 100 Mbps access  
line cards in various combinations, including fiber optic distance support up to 100  
km. All cards are compatible with any Fast Ethernet device.

Installation Guide  
Follow the simple steps outlined in this section to install and start using the  
Radiance access line cards.  
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 Cards  
Your order has been provided with the safest possible packaging, but  
shipping damage does occasionally occur. Inspect your line card(s)  
carefully. If you discover any shipping damage, notify your carrier and  
follow their instructions for damage and claims. Save the original  
shipping carton if return or storage of the cards is necessary.

Set the Switches  
MDI-II to MDI-X Switch (twisted-pair ports only)  
To eliminate the need for crossover cables, the access line card has an  
2
MDI-II to MDI-X switch on its twisted-pair port. The switch is located  
on the center of the front panel. Use this switch to configure the port for  
either a straight-through or crossover connection.  
• The parallel symbol (II) indicates a straight-through or parallel  
connection. The switch is up. (default)  
• The cross symbol (X) indicates a crossover connection. The switch is  
down (depressed).  
Use the following table as a guide.  
A device that is wired straight through needs one crossover connection:

DIP Switches  
A bank of six DIP switches is located on the back of the card. Switches  
1, 3, 5 and 6 allow you to select from several modes of operation.  
These switches are clearly marked on the card’s circuit board. Refer to  
the table below for the proper setting of the DIP switches.*  
When setting DIP switches, the UP position is when the lever of the  
DIP switch is pushed away from the circuit board. The DOWN position  
is when the lever is pushed toward to the board.

Link Loss Carry Forward  
Link Loss Carry Forward (LLCF) is provided as an aid in troubleshoot-  
ing a remote connection. When LLCF is enabled, loss of the receive  
signal at the TX port prevents the FX port from transmitting an idle  
signal onto the cable. Conversely, if the FX port does not detect a  
receive signal, the TX port does not transmit an idle signal.  
When LLCF is disabled (default), the card continually transmits idle  
signals on both ports.  
Warning: If LLCF is enabled on a remote access line card and there is  
no link on the cards copper port, you will NOT be able to manage that  
remote card.  
Refer to Link Loss Carry Forward for further details.  
Auto-Negotiation  
Auto-negotiation (AN) is only supported on the copper port. Enable AN  
to establish a full duplex connection with another auto-negotiating  
device or to force the port to half duplex.  
When AN is enabled, the copper port advertises 100Mbps and full/half  
duplex capability. The line card cannot auto-negotiate speed, which is  
set to 100Mbps.  
When AN is disabled (default), the copper port is set to full duplex.  
IMPORTANT: The duplex mode of the device connected to the fiber  
port must be the same as the copper ports connection.  
Link Loss Return  
Link Loss Return (LLR) is only applicable to the fiber optic port. When  
LLR is enabled, loss of the receive signal at the port disables its own  
transmit link.  
When LLR is disabled (default), the fiber port continually transmits an  
idle signal.  
Refer to Link Loss Return for additional information.

Installation Guide  
 
Far End Fault  
Far End Fault (FEF) is only applicable to the fiber optic port. FEF  
enables the locally managed access line card to detect a break in the  
remote card’s fiber port receiver. The remote card sends an alarm to the  
locally managed card if the remote card has FEF enabled and it loses its  
receive (RX) fiber link. No alarms are issued if FEF is disabled.  
Install the Line Card  
The Radiance access line card offers the ease of plug-and-play installa-  
tion and is hot-swappable. The card must be firmly secured to the  
chassis before network connections are made. Follow the simple steps  
outlined below to install your line card.

• Slide the card in until the top and bottom edges of the front panel are  
flush and even with the top and bottom edges of the chassis.  
• To secure the line card to the chassis, turn the thumbscrew clockwise  
until it is snug. The card is now properly installed and ready for  
connection to the network.  
• It is not necessary to install a management card in the remote chassis  
containing an access line card. Management of the remote access  
line card is provided through the local management card and the  
fiber link connecting the two access line cards.  
Connect to the Network  
To connect the card to the network, insert the cables into the appropri-  
ate connectors as illustrated below. Make sure the card is secured to the  
chassis before making network connections. Once power is applied to  
the unit, correct connectivity can be verified via the link (LK) LED.

Twisted-Pair Interface  
The twisted-pair port provides a shielded RJ-45 connector that supports  
a maximum segment length of 100 meters. Use only Category 5 cables.  
Fiber Optic Interface  
The fiber optic interface’s receiver is located above its transmitter.  
When making network connections, make sure that the fiber receiver of  
the card connects to the transmitter of the connected device. Make sure  
that the receiver port of the connected device connects to the fiber  
transmitter of the line card.  
The R231-13 and R231-15 fiber optic multimode interface supports a  
maximum segment length of 2 km for remote links.  
10  
Installation Guide  
 
The singlemode (SM) connector supports a maximum segment length  
of 20, 40, 60, or 100 km, depending on the model.  
NOTE: To enable remote management, make sure the management  
(MAN) LED is ON after connecting the fiber cable to the remote  
access line card. If not, reset one of the access line cards via software  
or a power cycle of the card.  
BWDM Interface  
The bidirectional wavelength division multiplexed (BWDM) port  
provides one pair of singlemode SC connectors that supports a  
maximum segment length of 20 km. BWDM line cards must always be  
used in complementary pairs. That is, a -1X model must always be  
connected to a -1Y. The -1X cards are designed to transmit data at a  
wavelength of 1550 nm and receive at 1310 nm. Correspondingly, the -  
1Y cards transmit data at 1310 nm and receive at 1550 nm.  
CWDM Interface  
The coarse wavelength division multiplexed (CWDM) port provides  
one pair of singlemode LC connectors that supports a maximum  
segment length of 60 km. The port’s wavelength (in nm) is printed on  
the front panel.

Software Settings  
Five operational functions on the access line card can be modified only through  
software commands,* either locally or remotely. Remote management communi-  
cations only occur on the fiber optic segment.  
Bandwidth Allocation  
This option allows you to specify the amount of incoming and outgoing data that  
can be carried over the network. The receive (RX) and transmit (TX) bandwidths  
are set through the copper port. The bandwidth can be set in 1Mbps increments  
from 1 to 100. Set both the TX and RX bandwidths to the same rate if you want  
the input and output bandwidth to be equal. Frames that overrun the allocated  
bandwidth are blocked, then dropped.  
When you set the RX bandwidth, the allocation is applied to traffic received on  
the copper port. When you set the TX bandwidth, the allocation is applied to  
traffic transmitted on the copper port.  
In addition to the bandwidth allocation, you can maximize performance by  
choosing the maximum burst size in each direction.  
Maximum Burst Size  
To accommodate for the fluctuations that commonly occur in network traffic, the  
Radiance access line card provides an option to specify the maximum burst size  
permitted in each direction. This allows your customers to have full access to  
their channel bandwidth until the burst threshold is reached. At that point the  
channel bandwidth is restricted for a period of time, depending on the bandwidth  
setting, until more data frames can be accepted. This arrangement benefits the  
customer who can take advantage of the channel’s full bandwidth, as long as the  
data burst size can be quantified and the burst is followed by a period of inactiv-  
ity.  
* Refer to the Command Line Interface Reference Guide, NetBeacon Element Management Software Installation &  
User Guide or WebBeacon Management Software Installation & User Guide for software management information.

16, 32, 64, 128 or 256 kilobytes.  
Loopback Mode  
You can enable loopback on either port on the locally managed card or on the  
remote fiber port. The loopback function allows a port to return its incoming  
data back to the sender, while continuing to receive and transmit management  
packets. The management packets are not looped back to the sender—only the  
data packets are returned.  
Loopback can only be applied to one port at a time (i.e., both ports on a card can  
never be in loopback mode simultaneously). This is because when you enable  
loopback on a port, the other port on the card is automatically disabled (no link).  
Because you would lose the ability to manage the remote access line card,  
loopback cannot be applied to the remote copper port. If a port is in loopback  
mode, its LBK LED will be lit.  
When loopback is enabled on a port, its incoming data is transmitted through the  
entire circuitry of the board, not just the port in loopback mode. This allows the  
entire circuit to be tested. RMON statistics are incremented on both ports—even  
though the physical interface on the port without loopback is neither transmit-  
ting nor receiving traffic.  
A full power cycle of the card takes it out of the loopback mode. Removing the  
card and reinserting it also takes it out of loopback mode because the loopback  
setting is not saved in the software’s persistence data file. Loopback is the only  
software switch setting that is not saved in this file.  
Typically, the remote card’s fiber port is placed in loopback mode to test the  
segment by using any standard packet-generating test equipment.  
Write Protect  
To prevent the remote access line card from controlling the locally managed  
card, set Write Protect to ReadOnly. Set Write Protect to ReadWrite if you want  
the remote card to be able to override software settings on the locally managed  
access line card.  
Port Enable/Disable  
Either port on a managed access line card can be enabled or disabled  
independently. When a port is disabled, its DIS LED is lit.

User Guide  
 
Disabling a port stops the data flow to and from that port. Although data is  
neither sent nor received, the disabled port continues to accept, process and  
transmit management packets. However, if LLCF is enabled and the opposite  
port has no link, management packets will not be transmitted.  
Remote Management Statistics  
Through SNMP management, NetBeacon or WebBeacon, you can view Remote  
Monitoring (RMON) and Ethernet statistics for the Radiance access line card.

Singlemode Fiber Optic Power Monitors  
Through software*, you can read the input and output power levels of the  
singlemode fiber optic port on the access line cards with diagnostic capabilities.  
Input Power Level  
The accuracy of the input power monitor is ±1 dBm from -28 dBm to -12 dBm.  
The accuracy is ±2 dBm from -31 dBm to -29 dBm. The monitor is  
unresponsive below -31dBm. If there are no cables connected to the fiber port,  
the software may display a reading of -40 dBm. The access line card peaks at -  
12 dBm and reaches saturation at -7 dBm.  
The singlemode long haul (R231-17) and extended long haul (R231-1J) ports  
are operational down to -34 dBm, which is too low for the monitor to measure.  
If the input power level is between -34 dBm and -29 dBm, a valid link will be  
established, however, the light level displayed by the software will show a  
reading of -40 dBm. This reading is not a failure indication; it simply means the  
level is beyond the range of the power monitor.

Link Loss Carry Forward (LLCF)*  
The access line cards incorporate an LLCF functionfor troubleshooting a remote  
connection. When LLCF is enabled, the ports do not transmit a link signal until  
they receive a link signal from the opposite port.  
The diagram below shows a typical network configuration with a good link  
status using access line cards for remote connectivity. Note that LLCF is enabled  
as indicated in the diagram.

If the fiber connection breaks, the card carries that link loss forward to the  
switch/hub which generates a trap to the management station. The administrator  
can then determine the source of the problem.

Important: When connecting a line card with LLCF enabled to an auto-  
negotiating device, force both sides of the configuration to 100Mbps and either  
full or half duplex. This allows the card to immediately see link pulses and start  
passing data.  
* Cards are shipped with LLCF disabled (OFF).

Link Loss Return (LLR)  
The fiber optic ports of the access line cards have been designed with an LLR  
function* for troubleshooting a remote connection.  
When LLR is enabled, the fiber port’s transmitter shuts down if its receiver fails  
to detect a valid receive link. LLR should only be enabled on one end of the link  
and is typically enabled on either the unmanaged or remote device.  
The diagram below shows a typical network configuration with a good link  
status using access line cards for remote connectivity.

aids the network administrator in determining the source of the loss.
