You can use the Hub 1000 SX downlinks to aggregate servers into server 
farms. First, install 3Com 3C985-SX Gigabit EtherLink

®

 Server NICs in 

each server. Then, connect up to eight servers through the downlinks. 
The hub’s optional gigabit interface connector (GBIC) uplink can connect 
to a 3Com SuperStack II Switch 9300 Gigabit Ethernet switch, thereby 
connecting to the network backbone. See Figure 3-1.

A power workgroup consists of a small number of servers, or a small 
number of sophisticated users on high-end workstations. Such a 
workgroup requires very high performance to run applications that 
move and process massive amounts of data in real time (for example, 
medical imaging, video editing, film postproduction, CAD/CAM, or 
digital prepress).

You can provide gigabit bandwidth to a power workgroup as shown in 
Figure 3-2.
