wherein each hub (137a, 137b) is configured to pass a third signal from the third port of the hub (137a,137b) to the fourth port of the hub (137a,137b), and to pass a fourth signal from the fourth port of the hub (137a,137b) to the third port of the hub (137a,137b), the locking system being adapted to pass lock status signals between locks (131a,131b, 127a,127b) coupled to the same hub (137a, 137b) as third and fourth signals in order to allow synchronic activation of these locks (131a,131b, 127a,127b). an authentication device; a power converter; a plurality of hubs (137a, 137b) coupled between the authentication device and the power converter, each of the hubs (137a,137b) including a first port, a second port, a third port, and a fourth port, wherein each hub (137a,137b) includes a first set of signal paths from a top edge of the hub (137a,137b) to the bottom edge of the hub (137a,137b), the first set of signal paths coupling the first and the second ports of the hub (137a,137b), and includes a second set of signal paths from a left edge of the hub (137a,137b) to a right edge of the hub (137a,137b), the second set of signal paths coupling the third and the fourth ports of the hub (137a,137b), with the signal paths of the first set of signal paths coupled to some of the signal paths of the second set of signal paths, and with others of the signal paths of the second set of signal paths not coupled to the first set of signal paths; and a plurality of locks (127a,127b,131a,131b), at least partially controlled by at least one processor for use in control of the locks, with each lock coupled to a one of the plurality of hubs (137a,137b), each lock including a housing and a processor within the housing for use in controlling operation of the lock; a plurality of pairs of drawer slides (129,125), each pair of drawer slides for mounting one drawer and including a first drawer slide and a second drawer slide, with a first lock of the plurality of locks engaging with the first drawer slide and a second lock of the plurality of locks engaging with the second drawer slide, the first lock and the second lock being coupled to a same hub, with the first lock coupled to the third port of the same hub and the second lock coupled to the fourth port of the same hub, wherein each hub (137a, 137b) is configured to pass a first signal from the first port of the hub (137a,137b) to the second, third, and fourth ports of the hub (137a,137b) and to pass a second signal from the second port of the hub (137a,137b) to first, third, and fourth ports of the hub (137a,137b) in order to provide authentication and power signals to the locks (131a,131b,127a,127b) and another hub (137a,137b) of the plurality of hubs;
