Disclosed is a power line broadband communication system having broadband coupler devices capable of direct electrical connection to an energized power line. Thus, the SCSI repeater can transparently connect independent SCSI buses that are connected to different devices with different requirements, preventing the slowest device from limiting the speed of the fastest device. The latching assembly is capable of receiving an end portion of the compartment cover such that the latching assembly requires less interactive force to receive the end portion than to release the end portion. The natural air-cooling radiator is attachable onto and detachable from the main transceiver section. A super-coolable composition is disposed within the core cavity of the thermal mass cooling core body encapsulating at least a portion of the cooling member.
