You can use the Hub 1000 SX downlinks to aggregate 10/100 Mbps
switches such as the 3Com SuperStack II Switch 1000, Switch 3000,
or Switch 3900. The Switch 1000 and Switch 3000 units must be
equipped with Gigabit Ethernet uplink devices (SuperStack II Switch
Gigabit Ethernet SX Module, part number 3C16925). The Switch 3900
has one built-in Gigabit Ethernet port, which can be used to connect with
the Hub 1000 SX.
First, install 3C16925 uplink devices in the SuperStack II Switch 1000
or SuperStack II Switch 3000 switches. Then connect up to eight
switches to the Hub 1000 SX through the eight downlinks. The hub's
optional GBIC uplink can connect to a 3Com SuperStack II Switch 9300
Gigabit Ethernet switch, thereby connecting to the network backbone.
See Figure 3-3.
The Hub 1000 SX does not support bandwidth aggregation (trunking).
