Attaching the 8-Port Interface Cable to a Bracket (Optional)

To attach the 8-port interface cable to a bracket, follow these steps:

---

Step 1 Place the molded RJ-45 end of the cable on the bracket with the RJ-45 ports facing you. Align the two holes on the molded RJ-45 end of the cable with the holes on the bracket. (See Figure A-2.)

Figure A-2 Placing the Molded RJ-45 End of the Cable on the Bracket

Step 2 You can align the molded RJ-45 ends of the cables in different ways by following either Step a or Step b.

a. Place the molded RJ-45 ends of the cables next to each other. This placement creates space between the last molded RJ-45 end of the cable and the edge of the bracket adjacent to it. Route the cables through this space. (See Figure A-3.)

Figure A-3 Routing Cables with Molded RJ-45 Ends of Cables Next to Each Other

b. Align the molded RJ-45 ends of the cables with an opening between each adjacent molded RJ-45 end of the cable. This placement creates space between each adjacent molded RJ-45 end. Route the cables through this space. (See Figure A-4.)

Figure A-4 Routing Cables with Molded RJ-45 Ends of Cables Flush with Bracket Edges

Step 3 Secure the molded RJ-45 ends of the cables to the bracket with the flathead screws provided to you. (See Figure A-5.)

---

Note To secure a single molded RJ-45 end of the cable, use the short flathead screws. To secure two (stacked) molded RJ-45 ends of the cables, use the long flathead screws.

---

Figure A-5 Securing the Cable Bracket to the Rack

Step 4 Use the end screws on the bracket to secure the cable bracket to the rack. (See Figure A-5.)

Step 5 Insert the 36-pin cable connector into the 36-pin port on the 24 CT1/CE1 card. Tighten the captive screws on the 36-pin cable connector to secure the cable to the 24 CT1/CE1 card. (See Figure A-6.)

SDH/STM-1 Trunk Card Optical Cables

To connect a device to the SDH/STM-1 trunk card, use a standard SFF-LC, SM (single mode), IM (intermediate reach) optical cable with either one duplex connector or two simplex connectors. (See Figure A-8 or Figure A-9.)

SDH/STM-1 Test Port Adapter Cable

This cable (Cisco part number: 72-2694-01) has a Test Port I/O Connector on one end to attach to the SDH/STM-1 card and a four-port Bantam jack adapter on the other end. Connect a standard Bantam jack test cable to the transmit and receive ports on the adapter. (See Figure A-10.)
