    Abstract: A modular network switch is disclosed. In an embodiment, removable interface modules and a switch circuit board (SMB) are housed in a chassis. Each of the interface modules includes a circuit board that is positioned in parallel with other interface modules. The SMB is oriented in a plane perpendicular to orientation planes of the interface modules, and the circuit boards are connected to the switch circuit board. A switch chip is electrically connected to SMB, and configured to switch network traffic between network connections of the interface modules. The chassis may include airflow regions separated by a divider with respective air intake vents. A power supply is housed in one of the regions and the SMB/interface modules are housed in another region. Power supplies provide power to the interface modules via a bus bar and provide power to the switch circuit board via a connection separate from the bus bar.

    Abstract: Modular network switches and other computer systems are described herein. A modular network switch can include a latching device for installing and removing computer modules (e.g., line cards) from an associated cabinet or enclosure. The network switch can also include interconnected computer modules (e.g., line cards, fabric cards, control modules, etc.) that include circuit boards oriented parallel to the flow of cooling air through the cabinet in the absence of a backplane or midplane oriented perpendicular to the air flow. The absence of such backplanes and/or midplanes provides a more direct air flow path through the cabinet, thereby enabling a more efficient flow of cooling air and lower operating temperatures. Additionally, the network switch can include an orthogonal arrangement of data planes, control planes, and/or power planes that can be efficiently interconnected to increase operational speed and further facilitate the flow of cooling air through the computer cabinet.

    Abstract: In an embodiment, a system for accelerated monitoring of optical transceivers includes a monitoring unit included in a port interface module of a network switch. The monitoring unit is configured to receive a monitoring configuration, obtain status information from a plurality of optical transceivers connected to the port interface module at an instance based on the monitoring configuration, and store the obtained status information and at least one associated timestamp in a memory. The memory is included in the port interface module and configured to provide the stored status information to a requestor external to the port interface module.
