Adjustable data rate data communications may be provided. First, a plurality of remote data rates at which a remote device is configured to operate may be received. Then, a plurality of local data rates at which a local device is configured to operate may be received. A greatest one of the plurality of local data rates may comprise a cable data rate comprising a greatest rate supported by a length of cable connecting the local device and the remote device. Next, an operating data rate may be determined. The operating data rate may comprise a highest one of the plurality of local data rates that has a corresponding equivalent within the plurality of remote data rates. The local device may then be operated at the operating data rate.

Adjustable data rates

Power Over Ethernet (POE)/universal power over Ethernet (UPoE) may be enabled at multigigabit port-channel connections. This may allow for additional speed support in auto-negotiation messages while employing multigigabit speeds. An integrated connector module (referred to herein as a 'ICM') compatible with UPoE with a modified local physical layer (PHY) circuit may be capable of supporting multi-gigabit data rates (such as between 1 G to 10 G, e.g., 2.5 G and 5 G) as to not limit the data rates to 1 G. The ICM may provide multi-gig data transmission through a first plurality of pins comprising a multi-gig data pin area. Furthermore, the ICM may provide UPoE power to support the multi-gig transmission through a second plurality of pins comprising a UPoE power pin area.

An example embodiment is illustrated to reduce power consumed by inactive connections. This embodiment may include detecting a connection condition signifying a requirement for an active connection between one network device and another network device. Thereafter, an enable instruction may be retrieved based upon the detecting of the connection condition, and a port may be enabled based upon the retrieved enable instruction resulting in increased electrical power consumption by a port component. The electrical power consumption may be increased relative to a prior level of electrical power consumption in which the port is disabled.

Power savings for a network device

A carrier module is physically compatible with a XENPAK/X2 10 GE slot and includes a socket for accepting a non-XENPAK/X2 module and interface circuitry for providing appropriate signals to a XENPAK/X2 70-pin connector on an interior side of the carrier module. The carrier module includes a cookie, accessible by host software, identifying the type of carrier module and non-XENPAK/X2 module accepted by the carrier card.

An improved rail includes two side portions, and a mid portion interconnected between the two side portions. The mid portion and the two side portions form a component that defines three sides of a transceiver module space. The rail further includes a blocking structure coupled to the component. The blocking structure is adapted to (i) permit a connecting portion of a transceiver module to connect with a connector when the transceiver module engages the rail and moves into the transceiver module space toward the connector and when a circuit board side of the transceiver module faces the printed circuit board, and (ii) prevent the transceiver module from contacting the connector when the transceiver module engages the rail and moves into the transceiver module space toward the connector and when a heat dissipation side of the transceiver module faces the printed circuit board.
