Aggregating	You can use the Hub 1000 SX downlinks to aggregate servers into server
Servers	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.

Connecting a	A power workgroup consists of a small number of servers, or a small
Power Workgroup	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.
