Management Unit

1-3

The two expansion connectors are used for adding components (additional hubs or a Management Unit) to create a hub stack. The LinkBuilder FMS 100-TX Hub can be used as a stand-alone repeater or as a stacked unit with other LinkBuilder FMS 100 Hubs. Stacking units provides the benefit of a higher port count, with the stack functioning as a single logical repeater. Up to eight units (for example, seven hubs and a Management Unit) can be connected together in a stack.

The rear panel of the hub provides a three-pronged socket for attaching a 100–240 V AC power cord to the hub. Alternatively, power can be supplied through a 3Com Redundant Power System (RPS) connected to the DC input connector. Refer to the section “Using the Redundant Power System” in Chapter 2 for additional information.

A 2 A, 250 V fast-blow fuse is located in the hub’s AC receptacle.

You can mount the LinkBuilder FMS 100-TX Hub in a 19-inch standard rack or you can place it as a stand-alone unit on a desk or table. A rack-mounting kit is supplied with each hub.

Management Unit The LinkBuilder FMS 100-TX Hub can support a Management Unit to provide full SNMP manageability to a hub stack. The Management Unit is designed for inclusion in 3Com’s SuperStack family of stackable network devices and can also be connected to the Redundant Power System (RPS). If a Management Unit is included in a stack, a maximum of seven hubs is allowed in the stack — that is, one Management Unit plus seven repeaters for a total of eight components, the maximum number of components allowed in one hub stack.

Only one Management Unit can be attached to each stack.
