An electrical machine, such as a router, switch, hub, etc. , includes a housing in which a Primary Backplane and Secondary Backplane are mounted in stacked spaced relationship. A primary Bus is fabricated on the Primary Backplane and a secondary Bus is fabricated on the Secondary Backplane. Connectors with feed through elements provide mechanical support and electrical transmission between the Primary Backplane and Secondary Backplane.

A network router for coupling a Local Area Network to a Wide Area Network such as the Internet or an intranet includes a smart card device for receiving and reading a smart card. The smart card will include information needed for permitting the router to access the Internet or intranet, such as an access phone number, an encryption key, configuration data, and an ID and password. A specified security level can also be stored within the information on the smart card to restrict such access.

A system for controlling staggered connection timing of an adapter module so that live insertion, or "hot swapping", may be performed with the adapter module, has a connector with staggered pins, i. e. , some pins being longer than others for initial contact with mating pins of a mating connector. The system further has a latch for controlling the timing of the connection of the staggered pins. As an adapter module is inserted into a housing, the latch allows the adapter module to be in one of three positions: (1) an entirely disconnected position where none of the pins of the adapter module are connected to the pins of the housing connector; (2) a "stopped", or partially connected, position where the longer of the staggered pins are connected between the housing and adapter modules connectors; and (3) a "fully-engaged" position wherein all pins of the connectors are engaged. The latch and the pin lengths are designed so that upon the longer pins making mating contact, the latch momentarily forces the module into the stopped position thereby allowing any circuits on the adapter module or elsewhere in the housing to sufficiently pre-charge.
