CHAPTER 4
CONNECTING TO THE NETWORK
This chapter outlines the procedure for connecting the BRIM-E100 to a
network.
4.1 CONNECTING THE BRIM TO THE NETWORK
The procedure for connecting network segments to the BRIM-E100
depends on which Fast Ethernet Interface Module is installed in the
BRIM. The FE-100TX Fast Ethernet Interface Module provides an RJ45
connection for Unshielded Twisted Pair (UTP) wiring. The FE-100FX
provides an SC style connector for use with multimode fiber optic
cabling. Refer to the following list and perform the procedure described
in the subsections that apply to your configuration:
• BRIM-E100 with FE-100TX Section 4.1.1
• BRIM-E100 with FE-100FX Section 4.1.2
Prior to connecting the network cabling check the connectors for the
proper pinouts as shown in Appendix A.
4.1.1 Connecting a UTP Segment to the BRIM-E100
The BRIM-E100 with an FE-100TX installed is often used to provide a
connection between the BRIM and a bridge, router, or switch. Usually, in
this configuration, a “straight-through” cable is used and the crossover
switch shown in Figure 4-1 is set to “not crossed over.”
Normally, when connecting devices to like devices, crossing over of the
transmit and receive pairs must occur. Before connecting a segment to the
FE-100TX, check each end of the segment to determine if the wires have
been crossed over for the proper connection. If the wires do not cross
over, use the switch on the FE-100TX to internally cross over the RJ45
port. Refer to Figure 4-1 to properly set the FE-100TX crossover switch.
