Radiance 10/100 Mbps Services Line Card

Overview
Chapter 1: Overview
Designed to support the new IEEE 802.3ah standard, Metrobility’s
Radiance R821 10/100 Mbps Services Line Card is a manageable two-
port copper-to-fiber device capable of remote communications with an
off-site unit. A third console port provides a connection for direct
management of the R821. Using an in-band management channel, two
Radiance services line cards in a back-to-back configuration can
communicate without a separate IP address at the remote end. Because
an IP address is not needed at every access point, this solution ideally
suits large metro access service deployments.
When paired with Metrobility’s NetBeacon
®
Element Manager, the
services line card provides the highest level of manageability with a user-
friendly graphical interface. NetBeacon delivers non-intrusive RMON
Group 1 statistics, errored symbol and frame event notifications, and
real-time information on power and temperature, along with Dying Gasp
capabilities.
Other advanced management features and diagnostics include Metro-
bility’s patent-pending Logical Services Loopback (LSL), rate limiting,
traffic prioritization into four service class levels, Q-in-Q double tagging,
PVID support, built-in copper line quality (CLQ) testing on the copper
port, integral temperature and transmit/receive optical power monitoring
on the fiber port, Link Loss Carry Forward (LLCF), Link Loss Return
(LLR), and Far End Fault (FEF). Rate limiting of user data allows control
over traffic speed and volume, thus maximizing bandwidth efficiency.
LSL, CLQ, LLCF, LLR, and FEF assist in testing and troubleshooting
remote connections.
Additional features include management access control which protects
the system and network connections from denial of service attacks from
the user’s network. By default, management access control automatically
discards unauthorized traffic received over the access port, making the
device impervious to all traffic conditions and traffic patterns. Access
control is also provided by reserving the 0x000 VLAN for use with
management. This management VLAN can be made unavailable to
users by changing the VLAN ID.

Two versions of the operational software, the FPGA firmware, and
configuration files can be stored on the services line card. New
embedded software can be downloaded easily in the field as upgrades
become available.
The 10/100 Mbps services line card can be managed as an independent
network interface device (NID) with its own IP address. As a NID at the
CPE demarcation point, the services line card responds to SNMP
requests addressed to unicast and subnet broadcast addresses by deliv-
ering information on its health and status as well as its network
connection. SNMP provides Internet-standard management and can be
used for surveillance and fault management.
The versatile R821-1S provides a 10/100BASE-T port (Port 1) and a
small form-factor pluggable (SFP) port (Port 2) with numerous
wavelength and distance options. Typically, Port 1 is designated as the
access port and Port 2 as the network port. To simplify device configu-
ration, a third console port is provided for direct access to the services
line card’s management agent.
Both Ethernet interfaces on the services line card support VLAN double-
tagging, baby giant frames (up to 1532 bytes untagged and 1536 bytes
tagged), and auto-negotiation. When auto-negotiation is enabled, the
copper port auto-detects MDI-II/MDI-X
1
. Both ports also support flow
control (forced collisions in half duplex and PAUSE frames in full duplex).

Safety Warning
Electrostatic Discharge Warning
Electrostatic discharge precautions should be taken when handling any
line card. Proper grounding is recommended (i.e., wear a wrist strap).
1. Unpack the Line Card
Your order has been provided with the safest possible packaging, but
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 card is necessary.
2. Set the Switches
A bank of six DIP switches is located on the back of the card. These
switches allow you to select from several modes of operation that only
affect the access port (Port 1). Functional switches are clearly marked on
the card’s circuit board. Refer to the following table 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 the board.

DIP Switches Auto-Negotiation (AN1)
AN1 is the auto-negotiation switch for Port 1. When auto-negotiation is
enabled, the port advertises 10/100 Mbps and half/full duplex capability
to its link partner. When auto-negotiation is disabled, the speed and
duplex for Port 1 are set through the SPD1 and DUP1 switches.
Note: Speed and duplex are dependent upon auto-negotiation. If AN1 is
enabled, the SPD1 and DUP1 switches will be ignored.
Speed (SPD1)
The speed switch applies to Port 1 and is effective only when auto-
negotiation (AN1) is disabled. Port 1 is set to 100 Mbps when SPD1 is
up, and 10 Mbps when SPD1 is down.
Duplex (DUP1)
The duplex switch applies to Port 1 and is effective only when auto-
negotiation (AN1) is disabled. Port 1 is set to full duplex when DUP1 is
up, and half duplex when DUP1 is down.
3. Install the SFP Optics
The R821-1S requires one small form-factor pluggable (SFP) optic.
Optics are shipped separately.
Table 1: DIP Switches
Switch
Label Position Description
AN1
UP (default) Auto-negotiation is enabled. Port 1 advertises 10/100
Mbps half/full duplex capability to its link partner.
DOWN Auto-negotiation is disabled. The SPD1 and DUP1
switches determine the speed and duplex for Port 1.
SPD1 UP (default) Port 1 is set to 100 Mbps when AN1 is disabled.
DOWN Port 1 is set to 10 Mbps when AN1 is disabled.
DUP1 UP (default) Port 1 is set to full duplex when AN1 is disabled.
DOWN Port 1 is set to half duplex when AN1 is disabled.

Installation Guide
Before installing the SFP module, make sure the bail latch is closed, as
shown below. Do NOT open the bail.
To install the optics, align the SFP module so the receiver (▲) is
positioned above the transmitter (▼). For a BWDM module, align it so the
visible part of the circuit board located at the back of the module is to the
right. The SFP’s circuit board should be on the same side as the LEDs.
Slide the module into the empty slot. Push the SFP firmly in place.
Important: The Radiance services line card is designed and tested to
operate using only Metrobility-supplied SFP transceivers. Safety, perfor-
mance, and reliability are guaranteed only when Metrobility transceivers
are used. Installing unspecified parts may damage the product and
will void the unit’s warranty.
4. Install the Line Card
The Radiance services line card offers the ease of plug-and-play instal-
lation 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.
•Grasp the card by the front panel as shown.

•Insert the card into a slot in the chassis. Make sure that the top and
bottom edges of the board are aligned with the card guides in the
chassis. Do not force the card into the chassis unnecessarily. It should
slide in easily and evenly.
•Slide the card in until the top and bottom edges of the front panel are
flush and even with the edges of the chassis.
•To secure the 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.venly.
5. Connect to the Network
To connect the line card to the network, remove the dust plug from the
SFP transceiver and insert the cables into the appropriate connectors as
illustrated below. Make sure the card is secured to the chassis before
making network connections.

Installation Guide
Twisted-Pair Interface
The twisted-pair port provides a shielded RJ-45 connector that supports
a maximum segment length of 100 meters.
Fiber Optic Interface
For maximum flexibility in designing or expanding your network, the fiber
port supports any of the following Metrobility-supplied small form-factor
pluggable (SFP) transceivers. Each transceiver provides as a set of LC
or SC connectors. The maximum distance and cable type supported by
the SFP transceivers is as follows:
Model # . . . . . . . . . . Distance . . . . . . . . Fiber Type
O280-M2 . . . . . . . . . . . . . 2 km . . . . . . . . . . . . . . .MM
O281-40. . . . . . . . . . . . . 40 km . . . . . . . . . . . . . . . SM
O281-80. . . . . . . . . . . . . 80 km . . . . . . . . . . . . . . . SM
O283-20. . . . . . . . . . . . . 20 km . . . . . . . . . . . . . . . SM
O383-20-xx . . . . . . . . . . 20 km . . . . . . . .SM (BWDM)
O483-80-xx . . . . . . . . . . 80 km . . . . . . . SM (CWDM)
Important: The distances noted are for reference purposes only. The
most important factor to achieve the desired distance is the optical power
budget. Metrobility specifications indicate the typical transmit power
budget. The actual distance is a function of the fiber type and quality, the
number and quality of splices, the type and quality of connectors, the
transmission loss, and other physical characteristics.

When making fiber optic connections, make sure that the transmit (TX)
optical fiber of the services line card connects to the receive (RX) optical
fiber of the connected device, and that the transmit (TX) optical fiber of
the remote device connects to the receive (RX) optical fiber of the
services line card.
BWDM Interface
The bidirectional wavelength division multiplexed (BWDM) transceiver
provides one singlemode SC connector that supports a maximum
segment length of 20 km. BWDM transceivers must always be used in
complementary pairs. That is, the O383-20-13 must be connected to the
O383-20-55.
The O383-20-31 transmits data at a wavelength of 1310 nm and
receives at 1550 nm. Correspondingly, the O383-20-55 transmits data at
1550 nm and receives at 1310 nm.
Use the link (LK) LEDs on the front panel of the card to verify correct
segment connectivity. As you insert the cable into each port, the LK LED
will be lit if the following conditions are met:
•Power is being applied to the chassis.
•There is an active device connected to the other end of the cable, and
it is sending idle link signals.
•All connections are secure and the cables are undamaged.
•Both ends of the cable are set to the same auto-negotiation state. To
maximize device compatibility, the R821 is shipped with auto-negoti-
ation enabled on both ports. If necessary, disable auto-negotiation and
set full duplex on the fiber port of the remote device to establish link.
