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.

An uninterruptible power supply includes a multipurpose data port that facilitates a plurality of communication methods including USB, serial and other communication methods, between the uninterruptible power supply and a host computer system. The multipurpose data port is configured to prevent interference if a user mistakenly connects a phone line or other similar but inappropriate line to the uninterruptible power supply. The multipurpose data port reduces the machine footprint needed to support multiple communication ports.

One aspect relates to a communication protocol for communicating between one or more entities, such as devices, hosts or any other system capable of communicating over a network. A protocol is provided that allows communication between entities without a priori knowledge of the communication protocol. In such a protocol, for example, information describing a data structure of the communication protocol is transferred between communicating entities. Further, an authentication protocol is provided for providing bidirectional authentication between communicating entities. In one specific example, the entities include a master device and a slave device coupled by a serial link. In another specific example, the communication protocol may be used for performing unbalanced transmission between communicating entities.
