Cisco nexus is their brand of datacenter switches. But also found this https://en.m.wikipedia.org/wiki/Google_Nexus https://en.m.wikipedia.org/wiki/Google_Nexus “ Upon the announcement of the first Nexus device, the Nexus One, the estate of science fiction author Philip K. Dick claimed that the Nexus One name capitalized on intellectual property from Dick's 1968 novel Do Androids Dream of Electric Sheep? and that the choice of name was a direct reference to the Nexus-6 series of androids in the novel.” Looks like there was a lawsuit, that was eventually settled out of court and we don’t know what was agreed.
