摘要： GBIC frames are mounted with respect to one or another or with respect to the printed circuit board so as to facilitate space sufficiency, e.g. of a front or other panel. In one aspect two GBIC frames are mounted in back-to-back fashion on opposite surfaces of a mounting plate of preferably minimal thickness. Plate cut-outs are positioned to accommodate frame feet or other mounting structures in a fashion off-set, on opposite faces, to avoid interference between frame legs. In one aspect, portions of GBICs and frames are received in cut-out or other edges of a PCB so that GBICs in frames straddle a major surface of a PCB to reduce height for accommodating 1RU or other form factors while increasing space efficiency.

The power is received at a connector jack comprising conductor pins configured to receive the power and data. A transceiver is configured to interface with the first portion and the second portion of the conductor pins of the connector jack. The power distribution paths are electrically isolated, and rectifying diodes are configured to interface with the conductor pins are also electrically isolated. The power is transmitted from the inline power device across the multiple power distribution paths.

摘要： Devices and methods are provided for enabling high-speed data communication at relatively low cost. Some methods allow devices to communicate by selecting a data transfer rate from among multiple data transfer rates. Some such methods allow devices to communicate according to the highest data transfer rate among multiple data transfer rates at which communications can be made without exceeding a predetermined error rate. Communications may be enabled between a first device operating at a relatively higher data transfer rate and a second device operating at a relatively lower data transfer rate. Pause frames or the like may be used to rate limit data received from the first device and maintain an average data transfer rate for communications with the second device at the lower data transfer rate.

摘要： A set of network communications devices shares available power among themselves to meet overall system power loading. An individual device is configured to include a local power supply delivering power to a local power bus at a local supply voltage varied in response to a voltage control signal. A protection component is connected between the local power bus and an external power cable used to connect the device to another device for sharing power. The protection component provides an interruptible low-impedance DC path for carrying current based on direction and magnitude of a voltage difference between the local power bus and the external power cable. Control circuitry is used to: (a) drive a current-sharing bus connected among the devices to influence a value of a system current-sharing signal indicating a level of system power loading among the devices; (b) generate a difference signal indicating a difference between local power loading of the local power supply and the system power loading reflected by the system current-sharing signal; and (c) generate the voltage control signal based on the difference signal to achieve a predetermined sharing of the system power loading by the local power supply.

摘要： In one embodiment, power from multiple inline power sources is collected. Power is supplied to powered network circuits from the collected power and any excess power from the collected power is supplied to downlink inline equipment. A worst-case power source loss scenario is determined based on power source and load information. Removal of an inline power source is detected and load power is reduced when the removed power source reduces the power required to operate the powered network circuits.
