CHAPTER 1
INTRODUCTION
The MMAC-M5FNB™ Multi Media Access Center offers
maximum flexibility and convenience in the design and operation of
your network.The enclosure provides space for one
Repeater/Management Module and up to five Media Interface
Modules (MIM™); or, by removing one of the five MIMs, you can add a
second, load-sharing power supply module.
This manual is an installation and reference guide. It lists the
features and options of the MMAC-M5FNB and explains how to
install the fan tray, power supply(ies), and security bars.You should
read through this manual prior to using the MMAC-M5FNB to gain a
full understanding of the MMAC-M5FNB and its capabilities.
CAUTION: Only qualified personnel should install or service this unit
and its modules!

1.2 USING THE MMAC-M5FNB MANUAL SET
Other manuals have been developed for the Repeater/Management
modules and for each MIM that can be installed in your
MMAC-M5FNB. These manuals explain how to install the individual
modules into the MMAC-M5FNB, how to attach cable segments to the
modules, and how to test those segments after they have been
installed. Specifications for all modules are included in each manual.
Additional manuals have been developed on how to use Cabletron
Systems’ Network Control Management software packages.
Each manual in this set assumes that you have a general working
knowledge of Ethernet or IEEE 802.3, 802.5, or FDDI type data
communications networks and their physical layer components.

1.4 THE MMAC-M5FNB MULTI MEDIA ACCESS CENTER
The Cabletron Systems MMAC-M5FNB is a complete modular
approach to integrated networks.The MMAC-M5FNB supports Local
Area Networks compliant to IEEE 802.3, IEEE 802.5, and FDDI
standards. It also supports all of the Cabletron Systems Media
Interface Modules (MIMs).
A variety of IEEE 802.3, IEEE 802.5, and FDDI compliant media can
be connected to the MMAC-M5FNB, including shielded and
unshielded twisted pair, fiber optic cable, thick or thin coaxial cable,
and standard AUI transceiver cable. Each media type has a MIM
which, when installed into the MMAC-M5FNB, is compatible with all
other MIMs installed in that unit.You can have complete network
integration of a variety of media through a single source.
The MMAC-M5FNB is designed so that network expansions or
changes in media types can be done without bringing down the entire
network. In a matter of minutes, you can add, change, or replace
MIMs without turning off the MMAC-M5FNB or using any special
tools.This design also allows the MMAC-M5FNB to adapt to
ever-changing industry standards. Figure 1-1 (following page)
illustrates an MMAC-M5FNB equipped with a variety of MIM cards.
CAUTION: Only qualified personnel should install or service this unit
and its modules!

1.5 MMAC-M5FNB FEATURES
Universal Power Supply
The MMAC-M5FNB power supply senses and automatically adjusts to
the input voltage and frequency. No additional adjustments are
necessary.
Built-in Power Supply Protection
The power supply module(s) automatically powers down under any of
the following conditions: thermal overload (thermal protection);
shorted output (over current, or short circuit protection); or excess
output voltage (over voltage protection).The power supply will
automatically recover when a thermal overload condition is corrected;
when an over current or over voltage condition is corrected, the power

supply requires AC power cycling (turn power switch off, then on
again) to recover.A FAULT LED on the power supply module indicates
when an over current condition has occurred.
Note: If you remove, then re-insert, the fan tray with no MIMs installed
in the chassis and the power on, you will have to turn each power
supply off, then on again to re-start.
Power OK Signal
The same signal that illuminates the Power OK LED on the power
supply module(s) will also alert the management module that the
power supply is functioning normally.
Power Factor Correction
The MMAC-M5PSM meets the EN60555-2 limits for power factor
correction, which may be required by utility companies in the near
future.
The power factor correction feature provides a number of advantages.
By improving this factor to meet the EN60555-2 limits, line noise and
peak current levels are dramatically reduced and the amount of power
available to the user is increased. Power factor correction also reduces
stress on fuses, circuit breakers, wall sockets, wiring, and
transformers.
Redundant Power with Current Sharing
The MMAC-M5FNB can operate with either one or two power supply
modules. If two MMAC-M5PSMs are installed, they share the power
load requirements of the installed MIMs; if one power supply fails,the
second automatically assumes the entire load.This ensures that your
network will remain operational until a replacement MMAC-M5PSM
can be installed.The two power supply modules use a current sharing
scheme such that each power supply provides 50% of the required load
( ± 5%, 5V output only) under all load conditions.
