DATA CENTER BEST PRACTICES GUIDE Cabling Installation (Front Side, Director Ports to Patch Panel): 1. Start cabling from the top ports (e.g. port 31). 2. Bundle the cables with Velcro in groups of eight to match the ASIC or trunk boundaries. This will facilitate servicing of the system through easy identification of the cable path. 3. Work your way down to the bottom port. 4. Bundle the 32 cables using Velcro (ports 0-31). CAUTION: Do not use plastic zip ties or metal tie wraps. These types of ties can cause sheathing and overstress the patch cables, causing signal loss. 5. Connect each cable to an LC patch panel port using the numbering schema defined in Appendix A. If you choose your own methodology, it is important to be consistent across all port blades and patch panel ports. This will minimize the confusion as to which director ports are allocated to which LC patch panel ports. Allocate 30-centimeters (12-inches) of slack at the patch panel to enable the patch panel's top and middle shelf to be raised into the up position for servicing. 6. Repeat Steps 1 through 5 for the second column of ports on the same blade (ports 32-63). 7. Bundle the 64 cables below the cable comb using Velcro. 8. Route the cables to the side of the rack (when facing the director, cables from director Slot 1-4 should be routed to the left and down; cables from director Slot 9-12 should be routed to right and down). NOTE: Do not route cables from Slot 1-4 towards the right as this could cause the fiber cables to be damaged if ICL cables are used in the configuration. 9. Each bundle of 64 cables is about 3.75 inches in circumference. Wrapping and labeling this bundle (68) with a cord management sleeve will protect the fiber and make it easier to identify and service the port blade.
