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.

4 Overview

The Radiance access line card provides the following key features:

• Remote management using Metrobility’s unique Radiance technology which

enables communication with an unmanaged remote device.

• Complete Remote Monitoring (RMON) Group 1 Ethernet Statistics support.

• Remote link testing capability that does not affect the customer’s available

bandwidth.

• User-selectable maximum burst size and bandwidth allocation.

• Individual port enable/disable.

• Far End Fault functionality to detect a loss of the remote card’s fiber port

receiver.

• Duplex auto-negotiation on the copper port.

• Half and full duplex support on the copper port.

• Write protect to enable or disable a remote line card from controlling a locally

managed card.

• Link Loss Carry Forward (LLCF) and Link Loss Return (LLR) functionality

to aid in troubleshooting.

• Push-button MDI-II/MDI-X switch on the front panel to eliminate the need

for crossover cables on the copper port.

• Fused power on each line card to protect the rest of the cards in the chassis

from a short circuit. The power (PWR) LED on an affected card is not lit if its fuse is blown.

• Hot swap circuitry.

• Auto-polarity on the copper port.

• Compliance with applicable sections of IEEE 802.3.

• Data frame size transparency.

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 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.

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 troubleshooting 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 card’s 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 port’s 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.
