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:

Full Duplex Functionality

Introduction

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 100B ASE-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

NOTE

Module installed is capable of operating at either 10 or 100
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:

Jitter

Cabling Requirements

Intersymbol interference and reflections cause jitter in the bit cell timing,
resulting in data errors. A 100B ASE-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. 100B ASE-TX transceiv ers 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

T est 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 en vironment 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 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.

connector on the twisted pair segment into the RJ45 port on the
module. See Figure 4-1.

2. Check that the RX LED on the BRIM-E100 is green or flashing yellow
(refer to Chapter 6). If the LED is off, perform each of the following
steps until it is on:

a. Check that the 100B ASE-TX device at the other end of the twisted

pair segment is powered up.

b. Verify that the RJ45 connector on the twisted pair segment has the

proper pinouts.
c. Check the cable for continuity.
d. Check that the twisted pair connection meets dB loss and cable

specifications outlined in Chapter 2, Section 2.1.
e. Check that the crossover switch is in the correct position.

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 dif ferent 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.
