Appendix E Cable installation and power separation guidelines Overview When installing Rugged RPs, cables that can withstand temperature extremes and inclement weather should be used. In outside environments, avoid contamination or damage to plugs. Plugs must be protected from sunlight and water in a suitable equipment housing or NEMA 4 rated box. It is also important to avoid exposure to water at cut ends of unfilled cables and cords.
Appendix E Cable installation and power separation guidelines Figure E-2. Cable with sock attached using tie wrap Sock Conduit Tie-wrap Feed the sock through the conduit and secure the sock on the terminal end of the cable with the tie-wrap. Once the sock and tie-wrap are in place, pull the cable through the conduit. Cable termination Before installing the Rugged RP, terminate the RP end of the Ethernet cable with the RJ45, IP67 connector provided in the box. Figure E-3.
Appendix E Cable installation and power separation guidelines Use the split grommet provided. Once it is in place, coat it with silicone to ensure the connector is sealed. Figure E-4. Assembling the connector on the RP end Cable splicing DRAFT Some cables are run in one piece from source to destination and have connector terminations. In other cases, two shorter pieces of cable need to be spliced together.
Appendix E Cable installation and power separation guidelines 2 Position the filled tube to overlap the end of the inner jacket and seal the gel. Clean off all excess sealant. NOTE: Tape can be used to stabilize the tube for immediate termination before the sealant sets. DRAFT Cable termination Shielded cables must be properly terminated, either grounded or isolated. For exposed installations requiring protection, the end of the shield can be bonded in various ways.

Appendix E Cable installation and power separation guidelines 3 Fold back the foil shielding and drain wire to expose the inner jacket. 4 Prepare the inner jacket for blocking the gel and direct burial. a Cut back the inner jacket b Trim the flute c Clean the excess gel NOTE: The flute can be cut longer to match the blocking tube length. DRAFT OneCell® Hardware Installation, Release 4.
Appendix E Cable installation and power separation guidelines Fill all space inside the tubing with B-sealant and position the filled tube to overlap the end of the inner jacket and seal the gel. 6 Fold the drain wire and foil back over the tube and position the foil to be folded back over the tube. DRAFT 5 E-8 M0303A2 4.5.
Appendix E Cable installation and power separation guidelines An extra piece of foil can be used to cover the foil seam. 8 For an HGS620 termination, wrap the drain wire at least two times around and position it where the spring clips will capture them. 9 Tape over the foil for stability. 10 Trim the wire ends.

Appendix E Cable installation and power separation guidelines Cable grounding For CAT-6A cables, the shield termination method is to use the ground lug and Bbond clip that are available in the 12A1 Grounding Kit. Fold the foil back over the jacket end and wrap the drain wire around the end and push the ground lug over the wrap. DRAFT 1 E-10 M0303A2 4.5.
Appendix E Cable installation and power separation guidelines Open the B-bonding clip to be placed and closed over the grounding lug. 3 The lug tail can be cut off or used for ground attachment. 4 Treat the inner jacket as described in step 4 on page E-7. OneCell® Hardware Installation, Release 4.
Appendix E Cable installation and power separation guidelines For an isolated shield termination, the 1572A and 1592A outer jacket foil and drain wire are removed a short distance back from the termination and electrical tape is used to isolate the foil end. Lightning protection CommScope recommends including lightning protection in your OneCell system to isolate equipment from surge damage.

The following link is for the recommended CommScope part. Ceiling connector 1 Terminate the indoor cable first – then lay down a bed of B sealant. OneCell® Hardware Installation, Release 4.
Appendix E Cable installation and power separation guidelines Clean all gel from the end of the OSP cable. 3 After the cable and conductors are positioned, fill the area around the cable end with sealant and close the connector housing. DRAFT 2 E-16 M0303A2 4.5.
Appendix E Cable installation and power separation guidelines Patch panel CommScope recommends installing a patch panel in the NOC to connect and manage CAT-6A cables. The following is a list of recommended CommScope 24 and 48 port patch panels and high density information outlets. • 760163436_HFTP-HD6B-1U-24 • 760163444_HFTP-HD6B-2U-48 • 760163451_HFTPA-HD6B-1U-24 • 760163469_HFTPA-HD6B-2U-48 • 760163519_HFTP-J6 • 760163527_HFTP-J10G For more information, go to CommScope.
