A system including a baseboard management controller (BMC) and a socket is described. The BMC is configured to provide a management interface to a network device. The socket is configured to accept an edge connector of a removable storage card. The BMC is configured to access via the socket at least a portion of the firmware of the BMC stored on the removable storage card.

Baseboard-management-controller storage module

Disclosed embodiments include a network switch having a first group of switch elements and a second group of switch elements. The second group of switch elements is cross-connected to the first group of switch elements to passively route network traffic through the network switch in accordance with a predefined configuration.

Lite network switch architecture

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.

Modular network switch

Disclosed embodiments include a network switch having a first number of switch elements and a second number of switch elements cross-connected to the first switch elements to passively route network traffic through the network switch in accordance with a predefined configuration.
