Abstract: In one embodiment, a method includes identifying optical transceivers installed in optical module ports at a network device based on input received at electrical interfaces at the network device, identifying at least one optical module port without an optical transceiver installed, determining if a plug is inserted into the optical module port, wherein an electrical signal indicates insertion of the plug into the optical module port, and raising an alarm if the optical module port is open. Insertion of the plug into the optical module port reduces airflow bypass, electromagnetic interference leakage, and contamination without the optical transceiver installed in the optical module port. The plug is also disclosed herein.

Abstract: In one embodiment, a transmission system includes a transmitter, a receiver, and a filter operable at one of the transmitter and the receiver to remove channel impairments. The filter is operable according to a sum of a Gaussian function and a reciprocal of cosine function, wherein the Gaussian and reciprocal of cosine functions comprise tunable parameters to account for skew and channel asymmetry.

Abstract: In one embodiment, a method includes transmitting data on two wire pairs carrying pulse power, wherein the pulse power comprises a plurality of voltage pulses with the voltage pulses on the wire pairs offset between the wire pairs to provide continuous power and identifying transitions between at least one of a pulse-on time and a pulse-off time, and a pulse-off time and a pulse-on time on at least one of the wire pairs. Data transmission on the wire pair is controlled during the identified transitions on the wire pair to prevent interference between the pulse power and the data.

Abstract: In one embodiment, a method includes receiving an indication at a modular electronic system of initiation of online removal for a module removably inserted into a slot of the modular electronic system, increasing a fan speed at the modular electronic system before the module is removed, monitoring an internal temperature at the modular electronic system, and providing an indication that the module is ready for removal upon reaching a specified cooling state at the modular electronic system based on the temperature monitoring. A panel on an adjacent module is opened and extends into the slot upon removal of the module to substantially block airflow bypass from the slot and maintain cooling within the modular electronic system. An apparatus and logic are also disclosed herein.
