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. Continued on next page

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. Continued on next page

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.

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. Continued on next page

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.

The laser light source on this equipment emits invisible laser radiation. Avoid direct exposure to the laser light source. Avoid personal injury! Viewing the laser output with optical instruments (such as eye loupes, magnifiers, or microscopes) may pose an eye hazard. • Do not apply power to this equipment if the fiber is unmated or unterminated. • Do not stare into an unmated fiber or at any mirror-like surface that could reflect light that is emitted from an unterminated fiber. • Do not view an activated fiber with optical instruments (e.g., eye loupes, magnifiers, microscopes). • 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.
6.
Repeat all the steps above as needed until the connector is clean.

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.
