Overview of the Model 281xSA Hub
The Model 2813SA and 2814SA Ethernet Hubs (see Figure 1-1 and
Figure 1-2, respectively) are preconfigured for plug-and-play operation. These
workgroup hubs support 10BASE-T Ethernet in a manageable, physical star
configuration using a building’s existing premises wiring. Model 281xSA
Ethernet Hubs offer a cost-effective solution for high-power, low-density
10BASE-T departmental segments, as well as the flexibility and expandability
to support medium-density 10BASE-T workgroups operating within a large
enterprise network.

management software.
