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

To attach the 8CT1/CE1 cable to a bracket:


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-7.)

Figure A-7 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-8.)

Figure A-8 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-9.)

Figure A-9 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-10.)


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-10 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-10.)

Step 5 Insert the 36-pin cable connector into the 36-pin port on the AS54-DFC-8CT1/CE1 card. Tighten the captive screws on the 36-pin cable connector to secure the cable to the AS54-DFC-8CT1/CE1 card. (See Figure A-11.)
