Abstract: A system provides a charging and a connection for a mobile unit. The system includes a housing of a mobile unit that couples to a latch. The housing comprises a loop and a panel. The loop is disposed on a top portion of the housing and receives a hook of the latch. The panel is disposed on a back portion of the housing and receives a corresponding panel of the latch. The panel includes a first set of electrical contacts that couple to a second set of electrical contacts of the corresponding panel to establish an electrical connection.

Abstract: A data switch includes multiple switching modules interconnected over a backplane. The data switch maintains flow integrity while path transitioning. The flow integrity can be maintained by temporarily disabling one or more of the switching modules from transmitting data units over the backplane for a flow undergoing a path transition. The disable condition is imposed when the path transition is commenced, and is lifted after the path transition is completed and an interval has passed ensuring that all data units for the flow transmitted to the backplane prior to imposing the disable condition have cleared the backplane. The backplane includes a multicast fabric and a unicast fabric, wherein flow path transitions are made from the multicast fabric to the unicast fabric upon source learning. All switching modules are temporarily disabled from transmitting data units having as a destination address an address undergoing source learning to the backplane.
