Installing the Prisma FiberLinX Gigabit Module
Follow these steps to install the Prisma FiberLinX Gigabit module in a Prisma
MediaCenter chassis or Prisma MediaCPE chassis.
1.
Turn the chassis power switch to OFF and disconnect the chassis from the
power source.
2.
Remove the blank bracket (if present) covering the slot where the module is to
be installed.
3.
Slide the module into the chassis using the card guides until the module is
seated securely in the connector.
4.
Secure the module to the chassis by tightening the captive screw(s).
5.
After installing the module, assign the Prisma FiberLinX Gigabit module an
IP address. Refer to Assign IP Information later in this document.
6.
Attach the network cables between the module and other devices that will be
interconnected.
7.
Plug the chassis into a power source and turn the chassis power switch to
ON.
Notes:
• The Prisma FiberLinX Gigabit module includes on-board SNMP logic. When
installed in a Scientific-Atlanta SNMP-manageable chassis, the Prisma FiberLinX
Gigabit module draws power from the chassis only. It is an independently
managed module.
• Since single-strand fiber products use optics that transmit and receive on two
different wavelengths, you must deploy single-strand fiber products in pairs, or
connect two compatible single-strand fiber products. The two connected products
must also have the same speed and distance capabilities.

Fiber Optic Cleaning Guidelines
Cleaning Optical Connectors
Cleaning fiber-optic connectors can help prevent interconnect problems and
therefore aid system performance. When optical connectors are disconnected and
reconnected, the fiber surface can become dirty or scratched. The goal of cleaning
the fiber optic connectors is to remove all dust and contaminants without leaving
any residue.
Required Equipment
The following equipment is required to clean the ends of fiber-optic connectors.
• Optical-grade (91%) isopropyl alcohol
• Lint-free wipes
• Compressed air (also called “canned air”)
Tips for Optimal Fiber-Optic Connector Performance
Follow these guidelines to ensure optimal connector performance.
• Connect or disconnect optical connector performance.
• Always use compressed air before cleaning the fiber-optic connectors.
• Use end caps on connectors when they are not in use.
• Always use compressed air to clean the end caps.
• Use optical-grade isopropyl alcohol of at least 91% or greater. Anything less than
91% isopropyl may leave a film on the fiber surface, creating more problems.
• Do not contaminate your alcohol supply.
− Use a sprayer (a fountain pump is also adequate)
− Do not put used alcohol back into the main container
• Use only lint-free wipes. Never use “Kleenex-type” tissues.
• If you have any degraded signal problems, clean the fiber-optic connector.

Cleaning Optical Connectors
Follow these steps to clean an optical connector.
1.
Remove loose dirt or dust from the end of the connector by using compressed
air (canned air) to blow dirt off the fiber and the connector.
2.
Dampen a lint-free wipe with optical-grade (99%) isopropyl alcohol. If no
wipes are available, use ferrule cleaner, part number 468517.
3.
Clean the end of the connector using the lint-free wipe or ferrule cleaner.
4.
Inspect the end of the connector for obvious contamination.
5.
Mate the connector with an adapter or cover with an end cap.

Assign IP Information
Assigning IP Information
In order for the Prisma FiberLinX Gigabit module to allow for SNMP-management,
the module must be assigned IP configuration information (e.g., IP address, subnet
mask, etc.) using iConfig via PrismaView software, the module’s serial port, or
DHCP. In addition to assigning an IP address and subnet mask, the former two
methods also allows you to create community strings, assign access rights, configure
traps, and more.
iConfig offers more options than serial port configuration (e.g., you can select which
traps to assign with iConfig). After assigning the Prisma FiberLinX Gigabit module
an IP address, you can use PrismaView software or another SNMP-compatible
Network Management System (NMS) to remotely configure, monitor, and manage
the Prisma FiberLinX Gigabit module.
Note: To access the Remote site’s Prisma FiberLinX Gigabit module and perform
upgrades using iConfig, Telnet, etc., assign the module its own unique IP address.

Software Configuration
Introduction
The following Prisma FiberLinX Gigabit module features are software configurable
via PrismaView software only:
• FX LinkLoss
• FiberAlert
• Bandwidth Control
• Loopback testing functionality
The following Prisma FiberLinX Gigabit module features are configurable via
PrismaView software or serial/Telnet session:
• Auto-Negotiation
• Selective Advertising
• Force Mode
• Flow Control
Refer to the Help file for configuration information. Refer to Serial
Configuration/Telnet Session later in this document.
Auto-Negotiation
The Prisma FiberLinX Gigabit module ships from the factory with Auto-Negotiation
enabled on the twisted-pair ports. In this mode, the ports negotiate for speed and
duplex.
Auto-Negotiation, Duplex Mode and Speed
The twisted-pair ports on the Prisma FiberLinX Gigabit module auto-negotiate for
speed and duplex mode. This device also provides the option of selectively
advertising or forcing the speed and duplex mode. The fiber port operates at 1000
Mbps Full-Duplex. Configure features on twisted-pair ports via the management
software. Refer to the Help file for configuration information.
Forcing the Duplex Mode and Speed
The twisted-pair ports on the Prisma FiberLinX Gigabit module can also be manually
set for 10 Mbps, 100 Mbps or 1000 Mbps operation and for Half- or Full-Duplex (i.e.
10 Mbps Full-Duplex, 10 Mbps Half-Duplex, 100 Mbps Full-Duplex, etc.).
Continued on next page
4008630 Rev B

19
Software Configuration, Continued
Selective Advertising
Selective Advertising, when used in combination with Auto-Negotiation, advertises
only the configured speed and duplex mode for the twisted-pair port.
Note: If a specific speed and/or duplex mode is desired, Scientific-Atlanta
recommends using Selective Advertising, rather than Force Mode, when connecting
to devices that ONLY auto-negotiate.
Bandwidth Control
The Prisma FiberLinX Gigabit module includes bi-directional bandwidth control by
independently set bandwidth from the TX Data Port to the FX Port and vice versa in
single Prisma FiberLinX Gigabit module solutions, and from the Host unit to the
Remote unit and vice versa in dual Prisma FiberLinX Gigabit module applications
(i.e., the bandwidth on the TX Data ports on both Host/Remote units is throttled).
Increments of bandwidth depend on speed; refer to the chart for granularity.
10 Mbps
4.88 Kbps per sec
100 Mbps
48.8 Kbps per sec
1000 Mbps
244 Kbps per sec
Loopback Testing
For troubleshooting, the Prisma FiberLinX Gigabit module includes Loopback
testing functionality, which loops back all frames arriving on the fiber port (except
for the device’s management traffic). When in Loopback mode, the Prisma
FiberLinX Gigabit module drops the link on the twisted-pair port.
Note: Loopback functionality is not an option for the Host when deploying Prisma
FiberLinX Gigabit modules in pairs.
Refer to the Help File for bandwidth control and Loopback configuration
information.

Software Configuration, Continued
FX LinkLoss and FiberAlert
The Prisma FiberLinX Gigabit module includes the troubleshooting features FX
LinkLoss and FiberAlert. When a fault occurs on the fiber segment of a conversion,
FX LinkLoss detects the fault and passes this information to the twisted-pair
segment. If a media converter is not receiving a fiber link, FX LinkLoss disables the
transmitter on the media converter's twisted-pair port. This results in a loss of link
on the remote twisted-pair device.
FiberAlert minimizes the problems associated with the loss of one strand of fiber. If
a strand is unavailable, the Prisma FiberLinX Gigabit module notes the loss of link.
The device will then stop transmitting data and the link signal until a signal or link
pulse is received. The result is that the link LED on BOTH sides of the fiber
connection will go out indicating a fault somewhere in the fiber loop. Using
FiberAlert, a local site administrator is notified of a fault and can quickly determine
the location of a cable fault.
Refer to the Help File for configuration information for these features.

Serial Configuration/Telnet Session, Continued
Is a VLAN tag required on Management packets? This refers only to management
from the TX and/or FX Data ports. If you say Yes, the device will ask you to enter a
VLAN ID. Configure both units in your Host/Remote application the SAME.
Are VLAN IDs required on the EXT port? You must answer Yes to the first question
in order to answer Yes to the second question. You can configure this question
differently on each unit.
Note: If only using the EXT port(s) for management, answer Yes to questions 1 and
2, then disable management on the Data ports by setting DIP switches 2 and 3 to
OFF.
Transparency Disabled
If you disable Transparency Mode, then you will receive the following screen and
can assign up to 32 VLAN IDs.
You can configure all ports on the Prisma FiberLinX Gigabit module to
accept/transmit VLAN-tagged packets. To enable VLAN functionality on the
Prisma FiberLinX Gigabit module, there must be a Y (Yes) under Tags for either the
TX Data port or the FX port (or both); if there is an N for BOTH the TX Data and FX
ports, VLAN functionality is disabled. Valid VLAN IDs are 1 to 4,094. You can also
set a Priority for port and SNMP VLAN traffic (see Priorities/Base VLAN Priority
section later in this document).
Continued on next page
32
Prisma FiberLinX Gigabit Module Installation Instructions
4008630 Rev B
Serial Configuration/Telnet Session, Continued
If you enable a port for Tags (Tagged Port), it will only accept and transmit VLANtagged packets. If a port is NOT enabled for Tags (Untagged Port), it will only accept
and transmit untagged packets.
Ports/Data VLANs
Type Y (Yes) under Tags for the FX port AND/OR the TX Data port.
• If you enable Tags on ONE of the above-mentioned ports (FX or TX Data), assign a
VLAN ID and Priority to the other port in the Ports section.
Note: When a tagged packet arrives on the Tagged Port, the Prisma FiberLinX
Gigabit module forwards the packet to the Untagged Port only if the VLAN ID in
the tag matches the VLAN ID defined for the Untagged Port. If an untagged
packet is received on the Untagged Port, the Prisma FiberLinX Gigabit module
adds a tag with the specified VLAN ID to the packet before forwarding it to the
Tagged port.
• If you enable Tags on BOTH the TX Data port and the FX port, assign up to 32
VLAN IDs in the Data VLANs section (rather than one in the Ports section).
Management VLANS
SNMP
When using VLAN functionality, always define an SNMP VLAN ID and Priority if
management is enabled on any port configured for VLAN-tagged traffic. Also in
this section, you can configure the TX EXT MGMT port to accept/pass VLANtagged packets by typing Y under EXT Tag.
Priorities/Base VLAN Priority
The Prisma FiberLinX Gigabit module has two outgoing queues; one for highpriority traffic and one for low-priority traffic. Use the PrismaView software to set a
Base VLAN Priority to designate what will be high priority and low priority.
• If the Base VLAN Priority is 4, 0-3 are low priority and 4-7 are high priority.
• If you change the Base VLAN Priority to 3, 0-2 are low priority and 3-7 are high
priority.
In the VLAN Configuration screen (shown previously), enter a Priority (0 - 7) for
each port and SNMP, if desired.

Serial Configuration/Telnet Session, Continued
Telnet
Assign the Prisma FiberLinX Gigabit module an IP address BEFORE using a Telnet
session (refer to Assigning IP Information earlier in this document). All
configurations that can be done via the serial port can also be performed using
Telnet.
Note: Use only one Telnet session at a time. Do not use an RS-232 serial session and
a Telnet session at the same time.
There are three levels of Telnet account access:
• User: Can only see status, change own password, reboot
• Operator: Can change settings
• Administrator: Can add/delete accounts, cleandb
Note: The serial port is always at the Administrator level.
DHCP
There is a Dynamic Host Control Protocol (DHCP) client in the Prisma FiberLinX
Gigabit module. By default, the DHCP client is disabled. If a DHCP server is
present on the network, the DHCP client will initiate a dialogue with the server
during the boot up sequence. The server will then issue an IP address, default
gateway, and subnet mask to the Prisma FiberLinX Gigabit module.
Once the new IP address is received, the Prisma FiberLinX Gigabit module will
reboot so that the new IP address will take effect.
Refer to Basic Device Configuration earlier in this document. If there is no DHCP
server on the network, make sure that DHCP is disabled and use iConfig or serial
configuration to manually set the IP addresses.
DHCP servers give out lease times; devices renew their leases based on the
administrator-specified time.
• If a device cannot renew its lease, and the lease expires, the device is given the IP
address 10.10.10.10 and reboots.
• If an IP address is already assigned to the device, and DHCP is then enabled, that
original IP address is saved.
• When DHCP is disabled, the saved IP address is reinstated and the device reboots.

Will you define VLAN IDs?
If you want VLAN traffic with specific tags on any/all of the twisted-pair ports (as
indicated in the following illustration), you will need to disable Transparency Mode
and define VLAN IDs (see Transparency Disabled earlier in this document). If you
want both tagged and untagged VLAN traffic, enable Transparency Mode (see
Transparency Enabled earlier in this document).

Application Examples
Introduction
The following are application examples for both VLAN and non-VLAN
environments. These are only examples and other implementations are possible. If
you require assistance configuring an application, contact Scientific-Atlanta technical
support.
There are three general types of installations:
• Transparency Mode (enabled) with untagged and tagged packets; VLAN IDs are
not defined;
• Non-VLAN environment with only untagged packets;
• VLAN environment using ONLY defined VLAN IDs; Transparency Mode
disabled.
Note: When configuring VLAN IDs, remember that you can use any between 1 and
4,094. The VLAN IDs used in the following applications are for example purposes
ONLY.
Host/Remote Application— Transparency Mode Enabled
In Host/Remote applications when using management on the TX EXT MGT port
and the FX Data port (management disabled on TX Data port) and you enable
Transparency Mode, both tagged and untagged traffic passes. Although you do not
have to define any VLAN IDs, Scientific-Atlanta recommends settings a specific
VLAN ID for SNMP management.

Troubleshooting
Troubleshooting the Prisma FiberLinX Gigabit Module
Condition
Possible Cause
If you cannot
establish a fiber link
• Make sure that the fiber transceivers on Prisma
FiberLinX Gigabit modules are not over/under driving
the fiber receivers. For fiber specifications, please contact
Scientific-Atlanta technical support.
• Make sure the fiber mode and wavelength on both
Prisma FiberLinX Gigabit modules match (i.e., both are
1310 nm single-mode fiber).
• If using the FiberAlert feature, make sure that FiberAlert
is enabled on only one unit when connecting two Prisma
FiberLinX Gigabit modules or when connecting a Prisma
FiberLinX Gigabit module to another Scientific-Atlanta
media converter which includes the FiberAlert feature.
If you cannot
establish a link on a
twisted-pair port
• Make sure cable connection is good; if not, replace the
cable.
Note: Prisma FiberLinX Gigabit module includes
AutoCross. You should detect link regardless of the
CAT-5 cable type.
• Make sure the port speeds on the Prisma FiberLinX
Gigabit module match those on the end devices
connected to the Prisma FiberLinX Gigabit module.
Scientific-Atlanta recommends configuring all connected
devices to Auto-Negotiation, or if using Force mode, be
sure speed and duplex match.
If two Prisma
FiberLinX Gigabit
modules are not
communicating
properly
• Make sure one is a Host and the other is a Remote. If the
second unit is NOT configured as a Remote, it will be
recognized as a Standalone unit and the Host and
Remote units will not communicate properly.

Troubleshooting, Continued
Condition
If management is
not functioning
properly
Possible Cause
• Make sure DIP switch settings are accurate for the port
you are managing.
• Make sure READ/WRITE Community Strings for the
Prisma FiberLinX Gigabit modules and PrismaView
software are the same.
• Make sure neither the TX Data port nor the TX EXT MGT
port on the Prisma FiberLinX Gigabit modules are
connected to the twisted-pair port on the Prisma
MediaCenter chassis.
To restore the unit
to factory default
settings
4008630 Rev B
• Use the cleandb function via the serial port (see Serial
Configuration/Telnet Session section earlier in this
document). This is especially helpful if you feel you have
made a mis-configuration. Scientific-Atlanta
recommends using this function on both units in
Host/Remote applications, then reconfigure all settings.
