3-14You are recommended to fasten the screws of each module right after you have inserted it.Connecting Interface CablesCable Routing RecommendationsInterface cables and power cords should be separately routed. Reasonable cable routing can improveefficiency by facilitating installation and removal of fan trays, PEM and some other components.An S12508 can connect up to 288 interface cables, with 144 cables respectively on the left and rightsides. An S12518 can connect up to 576 interface cables, with 288 cables respectively on the left andright sides.Workbench-mounted switchAll interface cables are routed at left and right sides of the chassis while power cords are routed at thechassis back. Interface cables are routed through cable management brackets to the cabling racks andthen up or down to the cabling trough.Rack-mounted switchz Interface cables are routed through the cable management brackets, bound at cabling racks onchassis sides, and then routed up or down to pass through the chassis top or the raised floor,depending on the available equipment room condition (that is, signal cables are routed into thechassis either from the cabling racks on the chassis top or from the cabling trough under the floor).z Put all the data signal cable adapters neatly under the chassis (instead of any places outside thechassis in case of unexpected damages).z The power cords run along the left-rear of the chassis and out of the chassis either from the chassistop or the raised floor depending on the equipment room conditions (power distribution cabinet,lightning protection box, and connector strip, etc.) of the exchange office.z Long cables can be bound with cable ties. Do not bind cables at the air exhaust vent to prevent thecables from aging too fast. For details, refer to Appendix A Cable Management.z Fix cables as near the device as possible. The cables between the fixing point and deviceinterfaces must be bound loosely.z To identify cables, you can stick labels on them. For details, refer to Appendix B EngineeringLabels for Cables.
