A multi-port cabling system for use in installing cable to an equipment rack or enclosure or within an equipment room or data center includes a cabling assembly comprising at least one connector head having a plurality of ports and at least one cable operatively connected to the plurality of ports. The at least one cable terminates internally within the connector head to operatively couple the cable to the plurality of ports. The system further includes a mounting bracket. The mounting bracket and the connector head are each configured for tool-less attachment of one or more cabling assemblies to the bracket. The mounting bracket is further configured to removably mount to an equipment rack or enclosure, and/or to a wall, to thereby install one or more cables. The cabling assembly and the cabling system help to eliminate on-site cable termination and testing during installation of cables to rack-mounted equipment.
