CHAPTER 1
INTRODUCTION
Welcome to the Cabletron Systems BRIM-E6 User’s Guide . This
manual explains how to install the Bridge/Router Interface Module
(BRIM) for Ethernet into Cabletron products that support BRIM
technology (e.g., the EMM-E6 or MicroMMAC). It also explains
BRIM-E6 features and specifications.
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-E6.A general working knowledge of Ethernet, and IEEE 802.3
type data communications networks and their physical layer components
is helpful when using the BRIM-E6.
Chapter 1,
Introduction , describes BRIM-E6 features, lists
specifications, and concludes with a list of related manuals.
Chapter 2,
Installation , describes how to install the BRIM-E6 into a
Media Interface Module (MIM) or a stand-alone product. This chapter
also explains how to install an Ethernet Port Interface Module (EPIM)
into the BRIM.
Chapter 3,
Connecting to the Network , explains how to connect network
segments to the EPIM.
Chapter 4,
Using the LANVIEW LEDS , describes how to use the
BRIM-E6 LEDs to monitor BRIM performance and status.
Appendix A,
EPIM Specifications , lists specifications for each of the
EPIMs available for the BRIM-E6.
Appendix B,
EPIM Cable Requirements lists cable requirements for
each of the EPIMs.

1.3 BRIM-E6 OVERVIEW
The BRIM-E6 extends the functionality of your individual MIM or
stand-alone hub to include Ethernet bridging capability. The BRIM-E6
has one user-configurable Ethernet Port Interface Module (EPIM)
interface. Cabletron Systems offers a variety of EPIMs that support
connections for Unshielded Twisted Pair, Shielded Twisted Pair,
Multimode Fiber Optic, Single Mode Fiber Optic, AUI, or Thin Coaxial
cable.
1.4 BRIM-E6 FEATURES
Ethernet Bridging
The BRIM-E6 adds an Ethernet bridged connection to any Cabletron
device with a BRIM expansion port. Refer to section 1.6 for more
information about Ethernet bridging.
MIB Support
For information on how to extract and compile individual MIBs, contact
Cabletron Systems Technical Support (see
Getting Help ).
LANVIEW Diagnostic LEDs
Cabletron equips the BRIM-E6 with a visual diagnostic and monitoring
system called LANVIEW. LANVIEW LEDs help you quickly identify
Bridge and Link status.
