Using FC-to-SC FDDI Adapters in the Cisco 4000 Series, Cisco 7000 Series, and Cisco 7500 Series Routers

Product Number: FC-SC-ADAPTER=

This publication contains instructions for making single-mode connections using FC-to-SC interface adapters (FC-SC-ADAPTERS=) in the Cisco 4000 series, Cisco 7000 series, and Cisco 7500 series routers.

FC-to-SC FDDI adapters allow newer versions of the Cisco 4000 series FDDI network processor module, and the FDDI Interface Processor (FIP), to be connected to existing FC-type optical fiber. All newer FDDI products are equipped with SC-type connectors and replace older versions of these products equipped with FC-type connectors; this FC-to-SC adapter prevents you from having to change the existing connectors on your FC-type fiber-optic cables. (You can also reverse the FC-to-SC adapter and use older FC-type, single-mode FDDI products with SC-type, single-mode optical fiber.)

This publication is for the FC-to-SC adapter installer, who should be familiar with electronic circuitry and wiring practices and have experience as an electronic or electromechanical technician.

This publication is to be used in conjunction with the following publications:

•For Cisco 4000 series users—Cisco 4000 Series Public Network Certification publication. If you have a Cisco 4000-M, Cisco 4500-M, or Cisco 4700-M router, also use this publication with the Cisco 4000 Series Installation Guide publication that shipped with your router. If you have a Cisco 4000, refer to the Cisco 4000 Hardware Installation and Maintenance publication. If you have a Cisco 4500 or Cisco 4700, refer to the Cisco 4000 Series Hardware Installation and Maintenance publication.

•For Cisco 7000 series or Cisco 7500 series users—use the FDDI Interface Processor (FIP) Installation and Configuration configuration note that shipped with your FIP. You can also refer to the hardware installation and configuration publications that shipped with your Cisco 7000 series or Cisco 7500 series routers.

Safety Recommendations

Follow these guidelines to ensure general safety:

•Keep tools away from walk areas where you or others could fall over them.

•Do not wear loose clothing that may get caught in the chassis. Fasten your tie or scarf and roll up your sleeves.

•Wear safety glasses when working under conditions that may be hazardous to your eyes.

Warning

Invisible laser radiation may be emitted from the aperture ports of the single-mode FDDI card when no cable is connected. Avoid exposure and do not stare into open apertures.

Following is an example of the warning label that appears on the product:

Figure 1 Warning Label on the Cisco 4000 series

Figure 2 Warning Label on the FIP

Note   The single-mode transmitter is designed to comply with specification 21, Code of Federal Regulations (CFR), Chapter 1, Subchapter J. The single-mode transmitter uses a small laser to transmit the light signal to the ring. Keep the transmit port covered whenever a cable is not connected to it.

•Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.

Safety with Electricity

Warning

Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground. This can cause serious burns or even result in welding to the terminals.

Follow these guidelines when working on equipment powered by electricity:

•Locate the room's emergency power-off switch. Then, if an electrical accident occurs, you can quickly shut the power OFF.

•Before working on the system, turn OFF the power and unplug the power cord.

•Disconnect all power before doing the following:

•Do not work alone if potentially hazardous conditions exist.

•Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, and missing safety grounds.

•Never assume that power is disconnected from a circuit. Always check.

•If an electrical accident occurs, proceed as follows:

•Use caution, and do not become a victim yourself.

•Turn OFF power to the system.

•If possible, send another person to get medical aid. Otherwise, determine the condition of the victim and then call for help.

•Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

Tools and Equipment Required

No additional tools or equipment are required to replace FC-to-SC connector adapters.

Older versions of the single-mode Cisco 4000 series network processor module and Cisco 7000 series and Cisco 7500 series FIP use simplex FC-type connectors (see ) for the transmit and receive ports. Newer versions of these products use simplex SC-type connectors. (See .) The connector accepts standard 8.7 to 10/125-micron single-mode fiber-optic cable. The single-mode interface supports connections at distances up to 6 miles (10 kilometers).
