If you place the hub on a desk or table, attach the supplied rubber feet to
each bottom corner of the hub. If you stack additional hubs on top of the
bottom one, place rubber feet on the bottom of each corner of each hub in
the outline shown on the unit's base.
To prevent hubs from possibly sliding off the stack, fasten each hub to the
hub below it by using the supplied brackets, as shown in Figure 2-4.

The LinkBuilder FMS 100-TX Hub chassis is equipped with a rear panel port
into which you can insert an optional 3Com transceiver interface module.
The transceiver interface module permits connections to a 100 Mbps Ethernet
station or a network backbone that is also running 100 Mbps Ethernet.
The two types of transceiver interface modules are shown in Figure 2-5.
Table 2-1 describes the two 100 Mbps modules.
