Instructions
Overview
Purpose
These installation instructions provide product information and instructions for
installing the Prisma® Gigabit Ethernet Media Converter module.
Introduction
The SNMP-manageable Prisma Gigabit Ethernet Media Converter module (for
simplicity in this document called “module”) provides a single conversion between
1000Base-T twisted pair and 1000Base-SX/LX fiber cabling. Each module includes
one RJ-45 connector and one pair of SC fiber optic connectors. The module installs in
modular, SNMP-manageable Prisma MediaCenter™ series of chassis as well as the
unmanaged Prisma MediaCPE™ chassis series.
The module is also available in a single-strand fiber version that allows two
wavelengths to share one fiber strand. Full-Duplex data travels on different
wavelengths (1310 nm and 1550 nm), doubling the capacity of fiber. It includes one
RJ-45 connector and one SC fiber connector.
Note: All modules, including 1300 multi-mode and 1310 single-mode (TX/LX), 850
nm multi-mode fiber (TX/SX), single-strand versions (TX/SSLX) and those with
CDWM, will be referred to as such throughout this installation guide except where

Configuration Instructions
Introduction
The Prisma Gigabit Ethernet Media Converter modules have user-configurable
features. Refer to the table in Switch Configuration Table later in these instructions
for available features.
Instructions for configuring both managed (via an SNMP-compatible management
application like PrismaView™ ) and unmanaged modules follow.
Managed Modules
To manage one or more modules, an SNMP agent must be present in the chassis:
some chassis have embedded management; other chassis use an SNMP management
module. To configure managed modules, install the module first. Refer to
Installing the Prisma Gigabit Ethernet Media Converter Module later in these
instructions for installation instructions. Then, configure using the management
software. Refer to the PrismaView software for Media Converters online help file for
more information and assistance.
Note: Management software will override hardware settings (e.g., jumper, switch,
etc.), so you MUST configure a module that will be managed via the software. Until
you configure a managed module via the software, the module (and its LEDs) may
not work properly.

About LinkLoss and FiberAlert
Introduction
The Prisma Gigabit Ethernet Media Converter modules include the troubleshooting
features FiberAlert and TX LinkLoss that help locate "silent failures" on your
network. It is vital to understand how FiberAlert and LinkLoss work, and how they
will react in your network configuration, before attempting to install the module(s).
CAUTION:
Installing modules without understanding the effects of FiberAlert/LinkLoss
can cause perfectly functioning units to appear flawed or even dead
About Link Integrity
During normal operation, link integrity pulses are transmitted by all point-to-point
Ethernet devices. When a media converter receives valid link pulses, it knows that
the device to which it is connected is up and sending pulses, and that the copper or
fiber cable coming from that device is intact. The appropriate “LNK” (link) LED is
lit to indicate this.
The media converter also sends out link pulses from its copper and fiber
transmitters, but normally has no way of knowing whether the cable to the other
device is intact and the link pulses are reaching the other end. The combination of
FiberAlert and LinkLoss allows this information to be obtained, even when physical
access to a remote device (and its link integrity LED) is not available.
What Is TX LinkLoss?
TX LinkLoss is a troubleshooting feature. When a fault occurs on the twisted pair
segment of a conversion, TX LinkLoss detects the fault and passes this information to
the fiber segment. If a media converter is not receiving a twisted pair link, TX
LinkLoss disables the transmitter on the media converter's fiber port. This results in
a loss of link on the device connected to the fiber port.

About LinkLoss and FiberAlert, Continued
What Is FiberAlert?
FiberAlert minimizes the problems associated with the loss of one strand of fiber. If
a strand is unavailable, the device at the receiver end notes the loss of link. The
device then stops 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 where a cable fault is located.
Note: Enable FiberAlert on ONE side of a media conversion only; enabling it on
both sides would keep both transmitters off indefinitely!
Using FiberAlert and LinkLoss
Modules ship from the factory with troubleshooting features disabled. To
enable/disable these features, please refer to the Configuration Instructions earlier
in these instructions, or the product’s help file.

Additional Gigabit Features
Master/Slave Mode
This Master/Slave mode feature determines which clock will be used between the
Prisma Gigabit Ethernet Media Converter module and the device it is connected to (a
switch, NIC, or another Prisma Gigabit Ethernet Media Converter module, etc.).
Slave mode is the default setting. In Slave mode, the module receives and uses the
clock of the connected device. Master mode uses the module's clock. The
Master/Slave mode is only valid for the twisted pair link.
This Master/Slave mode feature is hardware configurable ONLY.
Preferred/Forced Mode
In addition to Master/Slave modes, the module also includes Preferred/Forced
modes for Master/Slave negotiation.
• Preferred mode helps determine whether the module should act as a Master or
Slave.
• Forced Mode should typically only be used when connecting to some legacy
switches, or when there is difficulty establishing a link.
This Preferred/Forced mode feature is hardware configurable ONLY.
Since most switches today typically function as Masters, we recommend configuring
the modules as indicated in the following chart.
DIP Switch
Setting
S1-1

FX Negotiation on the Prisma Gigabit Module
The modules include the FX Negotiation feature that negotiates duplex mode. The
default for this feature is disabled. You must enable or disable this feature on both
ends of the connection or you may have difficulty establishing a link. If the device
you are connecting to the module does not support this auto-negotiation feature,
disabling the feature on the module forces the link up.

Installing the Prisma Gigabit Ethernet Media Converter Module
Introduction
Prisma series modules install in an SNMP-manageable Prisma MediaCenter chassis
or in Prisma MediaCPE chassis.
Installing the Module
Follow these steps to install a module.
1.
Remove the blank bracket covering the slot where the module is to be
installed by removing the screws on the outside edges of the bracket.
2.
Slide the module into the chassis, via the card guides, until the module is
seated securely in the connector.
3.
Secure the module to the chassis by tightening the captive screw.
Note: Save any “blanks” removed during installation for future use should
configuration requirements change.
Installation Tip: When testing, we recommend testing modules first in an
unmanaged environment. To do this, disable management (turn management off or
remove the management module from the chassis), follow the unmanaged
configuration instructions, then install the unit, connect the cables and test the LEDs.
When finished, re-activate management and configure the unit via the software.
Installation Tip: 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.
Twisted Pair Crossover/Pass-Through Connections
The modules support both crossover and straight-through Cat5 twisted pair cabling
types of connections with AutoCross, a feature that automatically selects between
the two, depending on the connected device.

Fiber Optic Cleaning Guidelines
Optical Connector Cleaning Overview
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.
• CLETOP or OPTIPOP ferrule cleaner (CLETOP Type A for SC, Type B for LC)
• Compressed air (also called “canned air”)
• Lint-free wipes moistened with optical-grade (99%) isopropyl alcohol
• Bulkhead swabs for LC or SC type connectors (choose appropriate type)
• Optical connector scope
Tips for Optimal Fiber-Optic Connector Performance
Follow these guidelines to ensure optimal connector performance.
• Do not connect or disconnect optical connectors while optical power is present.
• Always use compressed air before cleaning the fiber-optic connectors.
• Always use end caps on connectors when they are not in use.
• Always use compressed air to clean the end caps.
• If you have any degraded signal problems, clean the fiber-optic connector.
• Advance a clean portion of the ferrule cleaner reel for each cleaning.
• Turn off optical power before making or breaking optical connections in order to
avoid microscopic damage to fiber mating surfaces.

• Use safety-approved optical fiber cable to maintain compliance with applicable
laser safety requirements.
Important: Ensure that no optical power is present prior to this procedure.
1.
Turn optical power off to the connector.
2.
Using an optical connector scope, inspect the connector for scratches, burns,
or other signs of damage.
Note: If the connector is damaged, replace the jumper.
3.
If the connector requires cleaning, swipe it across the face of the appropriate
ferrule cleaner several times.
Result: This will remove dust and some films.
Note: You may hear a slight "squeak" while cleaning the connector,
indicating that it is clean.
16
4.
Inspect the connector again. If the connector requires further cleaning, clean it
using 99% isopropyl alcohol and a lint free wipe.
5.
Swipe the connector across the face of the appropriate ferrule cleaner several
more times to remove any film left by the alcohol.

Installation Troubleshooting
Troubleshooting
• During installation, first test the fiber and twisted pair connections with all
troubleshooting features disabled, then enable these features, if desired, just before
final installation. This will reduce the features’ interference with testing.
• When working with units where the features cannot be disabled, you must
establish BOTH your twisted pair and fiber connections before the link LEDs will
illuminate.
• If using a high powered device (which is designed for long distance installations)
for a short distance installation, the fiber transmitters may overdrive the receivers
and cause data loss. If this is the case, you may need to add an optical attenuator
to your connection.
