E-2APPENDIX E: CABLING REQUIREMENTS

Consult the cabling system plan to set up the cable labeling and record keeping system best suited to the environment. Also consider the following recommendations:

Identify cables by securely attaching a label to the ends of all cables.

Draw a floor location grid matrix using the building floor plans. For easy reference, use this grid when assigning location numbers to cables.

Assign a unique block of sequential numbers to the group of cables that run between each pair of wiring closets.

Assign a unique identification number to each distribution rack.

Make all work areas and wiring closets easy to identify by labeling the front panel of the CoreBuilder 7000 and other hardware and by displaying the floor location grid and cabling plan in each wiring closet.

Keep accurate and up-to-date cable identification records, such as IBM's Cable Identification Label Sheet or Cable Schedule. Post records near each distribution rack. On the appropriate cable schedule, record the following cable drop information: the cable source, destination,

￿jumper location, and any additional information.

Make sure that optical and coax cables are labeled Rx and Tx accordingly.
