A network switch subrack in a cabinet system is configured to bear a network switch. The network switch subrack includes an outer frame that is configured to be plugged into the cabinet. The outer frame includes a cavity sized to accommodate the network switch. The network switch subrack further includes a fastening assembly that is disposed in the outer frame and configured to fasten the network switch in the cavity in the outer frame. The network switch subrack further includes a transfer module having a first end pluggably connected to the cabinet system and a second end pluggably connected to the network switch.

A tower-mounted networking device facilitates deploying a remote station without having to build a custom station aside a radio tower. The networking device's chassis comprises a mounting bracket, which includes a curved contour for mounting the networking device on the radio tower. Also, the chassis can be resistant to weather intrusion, by not including a vent, to allow the networking device to be installed outdoors. The networking device can include a first power port coupled to an external connection line from a source external to the tower, such that the external connection line provides at least power to the networking device. The networking device can use the power to power a set of antenna mounted on the radio tower. The networking device can also relay a network connection between a pair of antennas, and/or between an antenna and a network connection to an Internet service provider.

Disclosed is a novel connector module structure, to be installed in a system to form connection between at least two functional modules. The connector module provides jumper connection capabilities, i.e., allowing one of its connection terminals to form electrical connection with a connection terminal of one or more particular non-adjacent connector modules.

One embodiment is directed to a tray for use in a subrack of a rack. The tray comprises a printed circuit board configured so that a plurality of connections can be made at a plurality of positions on the printed circuit board, each of the plurality of connections involving at least one connector positioned on a patch side of the plurality of positions and the least one connector having a device associated therewith in which information is stored. The tray is configured so that either side of the positions can be used as the patch side. The tray is configured so that the devices associated with the connectors involved in making the connections at the patch side can be read via the tray. The devices associated with the connections can be implemented, for example, using RFID tags or connection point identifier (CPID) storage devices (such as EEPROMs).

A connection apparatus includes: a housing case, where the housing case includes a first side face and a second side face that are intersected and disposed adjacent to each other; a first connector, disposed on the first side face and configured to be connected to a connector of a first line card, so that the connection apparatus is orthogonally connected to the first line card; and a second connector, disposed on the second side face and connected to the first connector. The second connector is configured to be connected to a connector of a network board. The connection apparatus can improve a capacity of the communications device.

A fiber panel system includes a chassis and at least blades configured to mount to the chassis. Each blade is moveable relative to the chassis between a retracted (closed) position and at least one extended position. Cable slack is managed at the front and/or rear of each chassis to facilitate movement of the blades without pulling or bending the cables beyond a maximum bend limit. Each blade may be locked into one or more positions relative to the chassis.

In some implementations, a switch card is provided. The switch card includes a set of switch chips configured to communicate data with a plurality of line cards. The plurality of line cards is coupled to a second switch card. The second switch card comprises a second set of switch chips. The switch card also includes a communication component coupled to the set of switch chips. The communication component is configured to determine whether the switch card should operate in a master mode or a slave mode. In response to determining that the switch card should operate in the master mode, the switch card is also configured to receive control plane data from a supervisor card. The switch card is further configured to communicate the control plane data to one or more switch chips of the set of switch chips and the second set of switch chips.

A connection apparatus includes: a housing case (31), where the housing case (31) includes a first side face and a second side face that are intersected and disposed adjacent to each other; a first connector (32), disposed on the first side face and configured to be connected to a connector of a first line card, so that the connection apparatus is orthogonally connected to the first line card; and a second connector (33), disposed on the second side face and connected to the first connector (32). The second connector (33) is configured to be connected to a connector of a network board. The connection apparatus can improve a capacity of the communications device.
