Overview
The Radiance 10/100Mbps interface line card provides seamless migration
between Ethernet and Fast Ethernet networks, in addition to built-in media
conversion allowing high-speed integration of fiber optic and twisted-pair
segments. A complete set of LEDs allows for quick status verification, and two
banks of DIP switches provide added versatility on each port. To optimize your
Ethernet network, each port operates independently in either half or full duplex.
The management functionality allows communication between the chassis and a
management station. This ability provides remote software control over the
Radiance line card configuration and notification of a failure to the management
station.
The Radiance 10/100Mbps interface line card offers the following key features:
• Auto-negotiation switch on the twisted-pair interface.
• Link loss auto-recovery on the fiber optic port.
• Link Loss Return (LLR) functionality to aid in troubleshooting a
remote network connection on the fiber optic port.
• Link Loss Carry Forward (LLCF) functionality to aid in troubleshooting a remote network connection.
• An MDI-II to MDI-X switch that eliminates the need for crossover
cables on the twisted-pair port.
• Flow control on each port in either half or full duplex mode.
• Store-and-forward switching to improve overall network performance by buffering packets during times of heavy congestion and
to prevent the forwarding of corrupted packets.
•A high-performance switching engine that performs forwarding and
filtering at full wire speed (148,800 packets per second).
• The ability to learn up to 1,024 MAC addresses.
• Low last-bit-in to first-bit-out delay.
4
• 128K bytes of buffer memory.
• VLAN tagging support.
• Discards packets with CRC errors, short packets (less than 64
bytes), or long packets (more than 1,518 bytes for un-tagged
frames and more than 1,522 bytes for IEEE 802.3ac tagged
frames).
• Compliant with applicable sections of IEEE 802.3, 802.3u, and
802.3x.
For updating or expanding an existing network, Metrobility offers line cards that
support a wide range of configuration needs. The Radiance 10/100Mbps
interface line cards support the following conversion combinations:
10/100Base-TX to 100Base-FX multimode SC
10/100Base-TX to 100Base-FX singlemode SC
10/100Base-TX to 100Base-FX multimode ST

Installation Guide
Follow the simple steps outlined in this section to install and start using
your Radiance 10/100Mbps 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
1
shipping damage does occasionally occur. Inspect your line card
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 unit is necessary.
Set the Switches
MDI-II to MDI-X Switch
2
To eliminate the need for crossover cables, the Radiance 10/100Mbps
interface line card includes an MDI-II to MDI-X switch for the twistedpair port. This push-button switch is located in the center of the front
panel and allows setup in either straight-through or crossover configurations.
When setting the switch, observe the positioning of the following
symbols:
• The parallel symbol (II) indicates a straight-through or parallel
connection. The switch is out. (default)
• The cross symbol (X) indicates a crossover connection. The
switch is in.
Use the tables below as a guide.
A device that is wired straight through needs one crossover connection:

DIP Switches
Two sets of DIP switches, located on the back of the line card, allow
you to select from several modes of operation. These switches are
clearly marked on the printed circuit board.

Auto-Negotiation Switch (AN1)
Switch AN1 controls the use of auto-negotiation on the copper port. To
enable auto-negotiation, push the lever UP. To disable this function,
push the lever DOWN. By default, auto-negotiation is enabled.
When the copper port has auto-negotiation enabled, it advertises
100Mbps full duplex capabilities. When auto-negotiation is disabled,
the port’s duplex is determined by the FD1 switch, and its speed is set
by the 100M1 switch.
Changes to switch AN1 only come into effect after the power-cycle
initialization.
*DIP switches also can be managed via console commands or with Metrobility’s NetBeacon™ or WebBeacon™
management software. Refer to the
Software Installation & User’s Guide
management information.

10/100Mbps Switch (100M1)
Switch 100M1 controls the speed setting for the copper port. If autonegotiation is disabled, the port speed will be the same as this switch
setting, where UP is 100Mbps and DOWN is 10Mbps. The default
speed setting is 100Mbps. When auto-negotiation is enabled, the
100M1 switch is ignored.
*
Half/Full Duplex Switch (FD1, FD2)
*
Switch FD1 determines the duplex mode for the copper port if autonegotiation is disabled. When auto-negotiation is enabled, the FD1
switch setting is ignored. Switch FD2 determines the duplex mode on
the fiber optic port. A port operates at full duplex when its FD switch is
UP. It operates at half duplex when its FD switch is DOWN. The
default is full duplex enabled (UP).
Link Loss Return Switch (LLR2)
The 10/100Mbps interface line card incorporates Link Loss Return
(LLR) functionality as an aid in troubleshooting remote connections on
the fiber optic port. When LLR is enabled, the loss of inbound link
pulses on the port stops the transmission of outbound link pulses on the
same port. For example, if LLR is enabled on port 2 and its receiver
(RX) stops detecting link pulses, then port 2’s transmitter (TX) will
stop sending link pulses. LLR is not applicable to the copper port.
Link Loss Return is enabled on Port 2 when switch LLR2 is UP. The
unit is shipped with LLR disabled. Refer to Link Loss Return in the
User Guide section of this manual for more information.
Link Loss Carry Forward Switch (LLCF)
In addition to LLR, the 10/100 line cards support Link Loss Carry
Forward functionality to help with troubleshooting remote connections.
Unlike LLR, which only applies to the fiber port, LLCF affects both
ports on the card. When LLCF is enabled, the loss of inbound link
pulses on a port stops the transmission of outbound link pulses on the
opposite port. For example, if LLCF is enabled, the loss of incoming
link pulses at Port 1 will stop the transmission of link pulses out of
Port 2. Conversely, if Port 2 stops receiving link pulses, Port 1 will not
transmit link pulses.
*Changes to the 100M and FD switch settings only come into effect after the power-cycle initialization.
