® 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

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) 1 carefully. If you discover any shipping damage, notify your carrie

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. 12 3 4 5 6 Switch Pn osition

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 l

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

• 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 th

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 leng

User Guide This section contains information about the operating features of the Radiance access line cards. LED Indicators The Radiance access line cards provide several LEDs on the front panel for the visible verification of unit status and proper functionality. These LEDs can help with troubleshooting and overall network diagnosis and management. There are separate receive (RX), link (LK), loopback (LBK) and disable (DIS) indicators for each port. The following table describes the indication

The maximum burst size can be adjusted to one of the following settings: 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

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. RMON Statistics Each port on the c

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

* Link Loss Carry Forward (LLCF) The access line cards incorporate an LLCF function for 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.

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
