Embodiments of the present disclosure provide a method and apparatus for reducing cross talk among pins in a connector. The apparatus may detect a bit error rate (BER) for each of a plurality of pins in a connector and compare the BER for each pin to a threshold BER. Responsive to determining that a set of pins among the plurality of pins each have a BER that is above the threshold BER, the apparatus may decrease the BER for each pin in the set of pins by selecting a subset of pins among the plurality of pins and adjusting operational characteristics of one or more of the subset of pins. The operational characteristics include a transmit power of the pin.

Reducing cross talk among connector pins

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 mechanism to mitigate assembly torsion on an electronics assembly is provided. The mechanism including an electronics assembly and a first connector, mounted to the electronics assembly with a lower portion of the first connector proximal to the electronics assembly and an upper portion of the first connector distal to the electronics assembly. The mechanism includes a spring, mounted so as to press the upper portion of the first connector and preload the first connector against assembly force imparted by assembly of the first connector to a second connector. A method to mitigate assembly torsion on an electronics assembly is also provided.
