MAKING FMS 100-TX HUB
C
ONNECTIONS
This chapter discusses how to use the LinkBuilder FMS 100-TX Hub in
various network environments. The chapter also discusses how to interpret
the hub’s LEDs and how to use the power-up disabled option.
Making Network
Connections
Table 3-1 summarizes the possible schemes for connecting the LinkBuilder
FMS 100-TX Hub in a 100BASE-T network. These connections are the only
ones permitted for a Class I device such as the LinkBuilder FMS 100-TX Hub.
Connections that use the 100BASE-TX module are identical to those that use
an RJ-45 port on the hub’s front panel.
