CHAPTER 1
INTRODUCTION
Welcome to the Cabletron Systems
BRIM-F6 User’s Guide
. This
manual describes features, explains installation procedures, and provides
specifications for the BRIM-F6 — Cabletron Systems FDDI Bridge/
Router Interface Module (BRIM).
The BRIM-F6 resides in, and provides additional connectivity/
functionality to, various Cabletron MIMs and hubs (e.g., the EMM-E6,
ESXMIM, NBR-420/620 or MicroMMAC). The BRIM-F6 utilizes two
FPIM (FDDI Port Interface Module) slots to provide you with the option
of using multimode fiber optic, single mode fiber optic, unshielded
twisted pair, or shielded twisted pair transceiver ports based on your
network requirements.

1.1 Using This Manual
Read through this manual completely to familiarize yourself with its
content and to gain an understanding of the features and capabilities of
the BRIM-F6.
In addition to having a general working knowledge of Ethernet and IEEE
802.3 type data communications networks and their physical layer
components, you should also understand FDDI networks and the ANSI
X3T9.5 standard prior to installing the BRIM-F6. For a review of FDDI,
see Appendix A,
Basic FDDI Networks
.
Chapter 1,
Introduction
, outlines the contents of this manual, highlights
BRIM-F6 features, and concludes with a list of related documentation.
Chapter 2,
Installation
, describes how to install FPIMs into the BRIM-F6
and how to install the BRIM-F6 into a Media Interface Module (MIM) or
a stand-alone hub.
Chapter 3,
Using LANVIEW
, describes how to use the front panel LEDs
to monitor BRIM performance.
Chapter 4,
Specifications
, lists various electrical and physical
specifications of the BRIM-F6.
Appendix A,
Basic FDDI Networks
, covers basic concepts of FDDI
networks, FDDI devices, and design/installation considerations.

1.3 BRIM-F6 Overview
The BRIM-F6 is an FDDI Bridge Router Interface Module (BRIM)
developed for use in Cabletron’s MMAC-FNB and MicroMMAC. The
BRIM-F6 can be used to provide a high-speed uplink from lower speed
networks such as Ethernet to a 100 Mbps FDDI backbone.
1.4 BRIM-F6 Features
Connectivity
The BRIM-F6 is equipped with slots for FDDI A and B ports. These two
ports allow connection to the ring as a DualAttached Station (DAS) using
two FPIMs or as a Single Attached Station (SAS) using one FPIM.
As a DAS, the MIM or hub that houses the BRIM-F6 connects directly to
the FDDI main ring. This provides the reliability of an FDDI dual,
counter-rotating ring topology. If one segment of the FDDI ring becomes
disabled, this dual ring configuration provides redundancy and restores
ring continuity.
As a SAS, the BRIM-F6 connects to the primary ring only by using a
single FPIM on the BRIM-F6 to attach to the M port of an FDDI
concentrator.
A dual homing configuration provides an additional redundancy feature
for the MIM or hub containing the BRIM-F6. Dual homing is a way of
connecting to an FDDI ring through the Master (M type) ports of two
separate dual attached concentrators. If one M type port or one segment
fails, the redundant port or segment activates automatically to retain
connection to the ring.
For more information regarding DAS, SAS or dual homing
configurations, refer to Appendix A,
Basic FDDI Networks
.
Bridging
The BRIM-F6 provides translational bridging between any channels or
ports in its host MIM or hub and the FDDI ring.

CHAPTER 2
INSTALLATION
This chapter contains instructions for unpacking the BRIM-F6, installing
FPIMs, and installing the BRIM-F6 into Cabletron devices that support
BRIM technology.
Note
: The BRIM-F6 is not shipped with the FPIMs installed. You must
order the correct FDDI Port Interface Modules based upon your network
requirements.
To install the BRIM and FPIMs, you need the following tools:
• 1 disposable wrist strap (provided with any BRIM, MIM or hub)
• 1 Phillips screwdriver.
Caution:
Observe all static precautions while handling modules.
2.1 Unpacking the BRIM and the FPIMs
Unpack the modules as follows:
1. Remove the shipping box material covering the module.
2. Carefullyremovethe modulefromthe shippingbox.Leave the module
in its static-shielding bag until you are ready to install.
3. After removing the module from its static-shielding bag, visually
inspect the device. If you notice any signs of damage, contact
Cabletron Systems Technical Support immediately.

2.2 Installing the FPIMs
To install an FPIM into the BRIM-F6:
1. Remove the screws securing the FPIM coverplate and the coverplate.
See Figure 2-1.
2. Insert the connector pins of the FPIM into the connector on the
BRIM-F6. See Figure 2-2.
Figure 2-1. Removing the FPIM Coverplate
3. Press down firmly on the FPIM until the pins slide all the way into the
connector holes.
4. Secure the FPIM with the screws provided.
