1.5 BRIM-E100 FEATURES  
Local Area Network (LAN) Connectivity  
The BRIM-E100 uses Cabletron Systems Fast Ethernet Interface Modules  
for LAN connectivity. You can easily install these Modules into the  
BRIM-E100 for the configuration of your choice.  
Fast Ethernet Interface Module connector and pinout  
information is located in Appendix A of this User’s Guide.  
NOTE  
Auto-Negotiation  
The BRIM-E100 when coupled with the FE-100TX module is capable of  
auto-negotiation for either 10 Mbps or 100 Mbps operation in full duplex  
or standard Ethernet (half duplex) mode. The device at the other end of  
the segment must also be capable of auto-negotiation in order to  
auto-negotiate full duplex mode. If the device is not capable of  
auto-negotiation, the BRIM-E100 senses the speed at which the device  
operates and switches to that speed in standard Ethernet mode.  
BRIM-E100 User’s Guide  
Page 1-3  
 
Chapter 1: Introduction  
Full Duplex Functionality  
The BRIM-E100 has the ability to transmit and receive at the same time.  
Full duplex operation allows the BRIM-E100 when coupled with the  
FE-100TX Fast Ethernet Interface Module to provide either 20 or 200  
Megabit bandwidth throughput as long as the device at the other end of  
the segment supports full duplex mode. The BRIM-E100 is also capable  
of operating in either full or half duplex mode at 100 Mbps when  
equipped with the Fiber Optic FE-100FX Fast Ethernet Interface Module.  
The BRIM-E100 is configured through Local Management on the  
management module (i.e., the EMM-E6, MicroMMAC, etc.) to operate in  
either full duplex (20/200 Mbps) or standard Ethernet (10/100 Mbps)  
mode.

CHAPTER 2  
CABLING REQUIREMENTS  
This chapter describes the cabling requirements for the BRIM-E100. The  
network must meet the requirements and conditions specified in this  
chapter to obtain satisfactory performance from this equipment. Failure to  
follow these guidelines could result in poor network performance.  
2.1 UTP CABLE SPECIFICATIONS  
The BRIM-E100 with an FE-100TX Fast Ethernet Interface Module  
installed provides an RJ45 connection that supports Unshielded Twisted  
Pair (UTP) cabling. The device at the other end of the twisted pair  
segment must meet IEEE 802.3u 100BASE-TX specifications in order for  
the devices to operate properly at 100 Mbps. Use Category 5 UTP cabling  
for networks operating at 100 Mbps. Category 3, 4, or 5 UTP cabling may  
be used for networks operating at 10 Mbps.  
The BRIM-E100 with an FE-100TX Fast Ethernet Interface  
Module installed is capable of operating at either 10 or 100  
NOTE  
Mbps. The FE-100TX automatically senses the speed of the  
other device and adjusts its speed accordingly.  
When connecting a 100BASE-TX Twisted Pair Segment to the  
BRIM-E100 twisted pair network port, the network must meet the  
following requirements:  
Length  
The IEEE 802.3u 100BASE-TX standard requires that 100BASE-TX  
devices be capable of transmitting over a 100 meter (328 foot) link using  
Category 5 UTP cable or Category 3, 4, or 5 cable for 10 Mbps operation.  
Impedance  
Unshielded Twisted Pair cables typically have an impedance from 85 to  
110 ohms.  
BRIM-E100 User’s Guide  
Page 2-1  
 
Chapter 2: Cabling Requirements  
Jitter  
Intersymbol interference and reflections cause jitter in the bit cell timing,  
resulting in data errors. A 100BASE-TX link must not generate more than  
1.4 nanoseconds (ns) of jitter. If the cable meets the impedance  
requirements for a 100BASE-TX link, jitter should not be a concern.  
Crosstalk  
Crosstalk is caused by signal coupling between the different cable pairs  
contained within a multi-pair cable bundle. 100BASE-TX transceivers are  
designed so that the user does not need to be concerned about cable  
crosstalk, provided the cable meets all other requirements.  
Noise  
Noise is caused by either crosstalk or externally induced impulses.  
Impulse noise may cause data errors if the impulses occur at very specific  
times during data transmission. Generally, the user need not be concerned  
about noise. If noise-related data errors are suspected, it may be necessary  
to either reroute the cable or eliminate the source of the impulse noise.  
UTP Propagation Delay  
Propagation delay is the amount of time it takes data to travel from the  
sending device to the receiving device. Total propagation delay allowed  
for the network is 256 bit times. 256 bit times is equivalent to 2.56  
microseconds (µs) at 100 Mbps operation or to 25.6 µs at 10 Mbps  
operation. If the total propagation delay between any two nodes on the  
network exceeds 256 bit times, then further segmentation of the network  
through the use of bridges or other devices is required.  
Temperature  
The attenuation of PVC insulated cable varies significantly with  
temperature. At temperatures greater than 40°C (104°F), Cabletron  
Systems recommends the use of plenum-rated cables to ensure that cable  
attenuation remains within specification.  
Page 2-2  
BRIM-E100 User’s Guide  
 
Multimode Specifications for the FE-100FX  
2.2 MULTIMODE SPECIFICATIONS FOR THE FE-100FX  
The BRIM-E100 supports the Cabletron Systems FE-100FX. The  
FE-100FX meets IEEE 802.3u standards. When connecting a fiber optic  
segment to the BRIM-E100 with the FE-100FX module installed, the  
network must meet the following requirements:  
Cable Loss  
Test the fiber optic cable with a fiber optic attenuation test set adjusted for  
an 850 nanometer (nm) wavelength. This test verifies that the signal loss  
in a cable is within an acceptable level. The maximum loss for a  
multimode fiber optic cable is 11.0 decibels (dB).  
Fiber Optic Budget and Propagation Delay  
Determine the maximum fiber optic cable length by calculating the fiber  
optic budget delay and total network propagation before fiber optic cable  
runs are incorporated in any network design.  
Fiber optic budget is the combination of the optical loss due to the fiber  
optic cable, in-line splices, and fiber optic connectors.  
Propagation delay (collision delay) is the amount of time it takes data to  
travel from the sending device to the receiving device. Total propagation  
delay allowed for the entire network is 256 bit times (2.56 µs). If the total  
propagation delay between any two nodes on the network exceeds  
2.56 µs, then further segmentation of the network through the use of  
bridges or other devices is required.  
2.3 NETWORK CABLE LENGTHS  
This section details the maximum network cable lengths specified by the  
IEEE 802.3u standard. As stated in the previous sections, the physical size  
of the network is limited primarily by propagation delay. The propagation  
delay cannot exceed 256 bit times.  
A 100BASE-TX/FX network might use all copper (UTP) links, all fiber  
links or a combination of both. The maximum length of any segment is  
determined by the types and combination of links and by the type of  
repeater (if any) between segments. IEEE 802.3u standards specify two  
repeater classes (Class 1 and Class 2) and the maximum cable lengths for  
each media type.  
BRIM-E100 User’s Guide  
Page 2-3  
 
Chapter 2: Cabling Requirements  
If you are installing this BRIM into a 100BASE-TX/FX environment with  
repeaters, use the repeater instruction manual to determine maximum  
cable lengths when laying out your network.  
UTP Maximum Cable Lengths  
An unshielded twisted pair copper segment in a 100BASE-TX  
environment may be no more than 100 meters in length.  
Multimode Fiber Cable Lengths  
The maximum distance between two Data Terminal Equipment (DTE)  
devices on a 100BASE-FX segment may be no more than 412 meters in  
half duplex mode or 2 Kilometers (DTE to DTE) in full duplex mode.

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  
BRIM-E100 with FE-100FX  
Section 4.1.1  
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  
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.

Connecting the BRIM to the Network  
4.1.2 Connecting a Multimode Segment to the FE-100FX  
The FE-100FX has an SC style network port (see Figure 4-2). Cabletron  
Systems supplies fiber optic cable that uses keyed SC style connectors to  
insure proper crossover of the transmit and receive fibers.  
An odd number of crossovers (preferably one) must be  
maintained between devices so that the transmit port of one  
NOTE  
vice versa.  
If you are using fiber optic cable that uses SC style connectors that do not  
resemble MIC style connectors or if the cable has SC connectors on one  
end and a different type such as ST connectors on the other, you need to  
ensure that proper crossover occurs. Read and follow the directions in  
Section 4.1.2.2, Fiber Connection: SC to ST.  
4.1.2.1 Fiber Connection: SC Connectors  
Do not touch the ends of the fiber optic strands, and do not let  
the ends come in contact with dust, dirt, or other contaminants.  
Contamination of the ends causes problems in data  
with alcohol using a soft, clean, lint free cloth.  
!
CAUTION  
1. Remove the protective plastic covers from the fiber optic ports on the  
applicable port on the module and from the ends of the connectors.  
2. Insert one end of the SC connector into the FE-100FX installed in the  
BRIM-E100. See Figure 4-2.

4.1.2.2 Fiber Connection: SC to ST  
Follow the directions in this section if you are connecting a non-Cabletron  
Systems device to the FE-100FX using different types of connectors such  
as SC to ST.  
The physical communication link consists of two strands of fiber optic  
cabling: the transmit and the receive. Connect the transmit strand from the  
applicable port on the module to the receive port of the fiber optic  
Ethernet device at the other end of the segment. Connect the receive  
strand of the applicable port on the module to the transmit port of the fiber  
optic Ethernet device.  
Label the fiber optic cable to indicate which fiber is receive and which is  
transmit. Cabletron Systems fiber optic cable is labeled so that one fiber is  
labeled 1, and the other fiber is labeled 2 at both ends of the cable. If the  
cable was not purchased from Cabletron Systems, label the cable as  
described above.  
Connect a fiber optic link segment as follows:  
Do not touch the ends of the fiber optic strands, and do not let  
the ends come in contact with dust, dirt, or other contaminants.  
Contamination of the ends causes problems in data  
transmissions. If the ends become contaminated, clean them  
!
CAUTION  
1. Remove the protective plastic covers from the fiber optic ports on the  
applicable port on the module and from the ends of the connectors on  
each fiber strand.  
2. Attach the fiber labeled 1 to the receive port on the FE-100FX. See  
Figure 4-3.  
3. Attach the fiber labeled 2 to the transmit port on the FE-100FX.  
4. At the other end of the fiber optic cable, attach the fiber labeled 1 to  
the transmit port of the device.

Displays the current active technology of the BRIM-E100. In the example  
shown in Figure 5-1, 100Base-TXFD (100 Mbps, full duplex) is the  
current operational mode.  
Desired Operational Mode  
This field allows the user to select the desired operational mode. The field  
toggles between 100Base-FX and 100Base-FXFD (full duplex) when a  
BRIM-E100 with an FE-100FX fiber optic Fast Ethernet Interface  
Module is installed.  
If an FE-100TX module is installed in the BRIM-E100, the field steps  
between Auto-Negotiation, 10Base-T, 10Base-TFD (full duplex),  
100Base-TX, and 100Base-TXFD (full duplex). In normal operation, the  
BRIM-E100 with an FE-100TX installed is capable of auto-negotiating  
the operational mode and no further user setup is required.  
In normal operation, the BRIM-E100 with an FE-100TX  
installed automatically establishes a link with the device at the  
NOTE  
other end of the segment without requiring user setup.  
However, Local Management provides the user with the option  
of manually configuring the BRIM-E100.  
Advertised Ability  
During auto-negotiation, the FE-100TX “tells” the device at the other end  
of the segment what its capabilities are. The capabilities of a BRIM-E100  
with an FE-100TX installed are 10Base-T, 10Base-TFD (full duplex),  
100Base-TX, and 100Base-TXFD (full duplex). In normal operation,  
with all capabilities Enabled, the BRIM-E100 “advertises” that it has the  
ability to operate in any mode. The Network Manager may choose to set  
up the BRIM-E100 so that only a portion of the available capabilities are  
advertised and the others are disabled. For example, only 100Base-TX  
and 100Base-TXFD might be enabled so that only devices that operate at  
100 Mbps can communicate with the BRIM-E100.
