The NetStacker II 12 port unmanaged hub provides 12 twisted pair ports. The 24 port managed hub provides 24 twisted pair ports. In addition, both hubs offer an expansion slot for a 100Base-FX interface so the user can slide a ﬁber- optic module into the rear panel. A slot for a 100Base-FX interface is also provided on the front panel, for use when the management module has been installed in the rear panel slot.

Both hubs automatically detect the speed (10Mbps or 100Mbps) of the devices they are connected to. For additional expansion, each hub provides an Uplink push-button for the 12th port, which can be cascaded to another hub by means of straight through cable.

The NetStacker II hubs can be stacked up to 8 units high and connected by means of the “Stack Connection In” and “Stack Connection Out” ports on the rear panel. In addition, one of the hubs in the stack may be equipped with a slide-in management module. The entire stack requires only one managed hub for all of the stacked devices to be managed. Each dual speed hub has its own ID, which is auto-detected and auto-conﬁgured. You do not have to conﬁgure the hub ID yourself.

Either model hub can be placed on a tabletop or rack mounted. With unmatched ﬂexibility, the hubs ensure operation in any LAN environment, regardless of size. The hubs provide the solutions that users require for their complex networks.
