Using This Manual - Cabletron Systems TRMIM-22 Installation Manual

INTRODUCTION
CHAPTER 1
INTRODUCTION
Welcome to the Token Ring Media Interface Modules
Installation Guide. This manual serves as a reference for installing
and troubleshooting Cabletron Systems TRMIM-22 , TRMIM-24 ,
TRMIM-42 , and TRMIM-44 .
The TRMIM-22, TRMIM-24, TRMIM-42, and TRMIM-44 comprise a
family of Token Ring Concentrator modules. The TRMIM-22 and
TRMIM-24 provide 12 and 24 trunk coupling unit (TCU) ports,
respectively, that support voice grade unshielded twisted pair (UTP)
cabling. The TRMIM-42 and TRMIM-44 have 12 and 24 TCU ports,
respectively, supporting IBM type 1, 2, 6, and 9 shielded twisted pair
(STP) cabling.
Both UTP concentrator modules and both STP concentrator modules
are equipped with RJ-45 modular connectors. The STP concentrator
module RJ-45 connectors provide for connection of the cabling shield.
All four concentrator modules are designed for installation in any
Cabletron Systems Multi Media Access Center (MMAC ) equipped
with a Flexible Network Bus (FNB ). All four concentrator
modules are IEEE 802.5 compliant and compatible with IBM
products.
NOTE: The term Concentrator Module is used throughout this
manual when describing features and functions that are common to
the TRMIM-22, TRMIM-24, TRMIM-42, and TRMIM-44. The terms
TRMIM-22, TRMIM-24, TRMIM-42, and TRMIM-44 are used when
it is necessary to describe features that are unique to any device.

1.1 USING THIS MANUAL

Prior to installing and operating your concentrator module, read
through this manual completely to familiarize yourself with its
contents and to gain an understanding of the features of the
concentrator module.
A general working knowledge of Token Ring (IEEE 802.5) networks
will be helpful when installing your concentrator module.
