Abstract
Low-cost network switches and other computing systems are described herein. A low-cost network switch can operate at a lower ambient temperature (e.g., 55° C.) than conventional switches, thereby enabling the use of lower cost components (e.g., optical components that are not rated for operation at up to 70° C.). The network switch can utilize a power bar pass-through card that provides power from an enclosure bus bar to components of the network switch in lieu of a power supply unit. Additionally, ports of the network switch can operate in a 2×50G mode in which a network switch port capable of communicating at 100 Gbps interfaces with two external ports each capable of communicating at 50 Gbps. Communication in 2×50G mode can be supported by a four-channel Y-cable, in which the four channels are utilized by the network switch port and fan-out to two channels to each of the two external ports.
