1.4 THE MMAC-M3FNB MULTI-MEDIA ACCESS CENTER
The Cabletron Systems MMAC-M3FNB is a complete modular
approach to integrated networks.The MMAC-M3FNB 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-M3FNB, including shielded and
unshielded twisted pair, fiber optic cable, thick or thin coaxial cable,

INTRODUCTION
Page 1-4
and standard AUI transceiver cable. Each media type has a variety of
MIMs, which, when installed into the MMAC-M3FNB, are compatible
with all other MIMs installed in that MMAC-M3FNB. You can have
complete network integration of a variety of media through a single
source.
The MMAC-M3FNB 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-M3FNB or using any special tools.
This design also allows the MMAC-M3FNB to adapt to changing
industry standards. Figure 1-1 illustrates an MMAC-M3FNB
equipped with a variety of MIM cards.

1.5 MMAC-M3FNB FEATURES
Removable Fan Tray
The MMAC-M3FNB is equipped with a removable fan tray, which
means that you can replace a failed fan unit quickly, without any
special tools.The fan tray incorporates an LED that indicates fan
status; the same signal that illuminates the LED also alerts the
management module that the fans are operating properly.

Universal Power Supply
The MMAC-M3FNB power supply senses and automatically adjusts to
the input voltage and frequency. It is designed to operate at 110 or 220
volts without any user configuration.
Built-in Power Supply Protection
The power supply module automatically powers down under any of
the following conditions: thermal overload (thermal protection);
shorted output (short circuit protection); or excess output voltage
(over-voltage protection).The power supply will automatically recover
when a thermal overload or shorted output condition is corrected;
when an over-voltage condition is corrected, the power supply requires
AC power cycling (turn power switch off, then on again) to recover.
Power OK Signal
The same signal that illuminates the Power OK LED on the power
supply module will also alert the management module that the power
supply is functioning normally.
Flexible Network Bus
The MMAC-M3FNB’s Flexible Network Bus lets you combine Token
Ring, FDDI, and Ethernet modules in the same hub. Cabletron
Systems offers a full line of media interface modules that let you
create new networks and extend and connect existing networks.
The fan tray is hot-swappable; however, the MMAC
chassis should not be run for extended periods of tim
e
without the fans installed, as it will quickly overhea
t.
The handles provided on the fan tray and power supply
are for installation only; they are not designed to
support the full weight of the chassis, and should no
t
be used as carrying handles.

INTRODUCTION
Page 1-6
Rack Mountable Chassis
The MMAC-M3FNB chassis can be mounted into a standard 19"
(48.26 cm) equipment rack. Separate rack mount brackets are
included that allow the unit to be flush mounted or recessed from the
front plane of the rack mount unit for safety and ease of network
connections.

INSTALLATION REQUIREMENTS AND SPECIFICATIONS
Page 2-1
CHAPTER 2
INSTALLATION REQUIREMENTS
AND SPECIFICATIONS
This chapter describes the following:
• Site guidelines that must be met before installing an
MMAC-M3FNB onto your network
• MMAC configuration guidelines
• Operating specifications for the MMAC-M3FNB enclosure and
power supply module
2.1 SITE GUIDELINES
The following guidelines must be followed when you select a site for
the MMAC-M3FNB. If not, unsatisfactory network performance may
result.
• An unrestricted free surface area of 8.3" (21.1 cm) high,
19" (48.3 cm) wide, and 17" (43.2 cm) deep is needed for
the MMAC-M3FNB enclosure.
The unit should be mounted
to allow the free flow of air around the chassis.
• If the MMAC-M3FNB is to be placed on a shelving unit, the
shelf must be able to support 35 lb (15.9 kg) of static weight.
• A USA standard 3 prong power receptacle must be located
within 2.13 m (7 ft.) of the site.
• The temperature of the location must be maintained between
5 ° and 40 ° C (41 ° to 104 ° F).Temperature changes of greater
than 10 ° C (18 ° F) per hour must not occur.
The handles provided on the fan tray and power supply
are for installation only; they are not designed to
support the full weight of the chassis, and should no
t
be used as carrying handles.

INSTALLATION REQUIREMENTS AND SPECIFICATIONS
Page 2-2
2.2 MMAC-M3FNB CONFIGURATION GUIDELINES
The MMAC-M3FNB has three slots: two that accept media interface
modules, or MIMs; and one for a management module.The slots are
numbered from bottom to top; slot #1 is a half-width slot reserved for
the management module. Cabletron Systems’ management modules,
such as the IRM3 and the EMME, are equipped with firmware-based
Local Management, which lets you manage the MMAC MIMs.
Management modules are also SNMP compliant,which means that an
MMAC equipped with a management module can be managed
remotely by any SNMP management software, including any one of
the SPECTRUM
®
for Open Systems suite of management products.
You can combine Token Ring, Ethernet, and FDDI MIMs in the same
MMAC; be sure to consult the appropriate management module and
MIM installation guides for detailed setup information.

LEDs
OK When lit, this green LED indicates that the
(Power Supply) power supply module is operating correctly; a
signal is also sent to the management/repeater
module to indicate that the power supply is
functioning properly.
Fail When lit, this red LED indicates a loss of input
(Power Supply) power, loss of regulation on any output, or the
activation of any power fail circuit protection.
The supplied power cord is not designed for European
installations. This unit is intended to be operated fr

Fan Tray LED This LED is green when both the fans are
(Fan Tray) operating properly. The LED turns red when
either fan slows to half speed or less, and
signals the management/repeater module that
there is a fan tray problem.
SAFETY
Designed in accordance with UL1950,UL910,NEC 725-2(b),CSA 950,
IEC950, EN55022 Class A. Meets FCC Part 15, Class A limits.
This unit must be assembled and used in accordance with the
instructions in this manual.
If you have not yet installed a repeater/management
module and/or a MIM or MIMs, the Fail LED may
remain lit until installed MIMs create a power load.
At
that time, the green (Power OK) LED will light.
NOTE
When the M3FNB is first powered up, this LED will be
red for a moment until the fans are operating at the
proper speed.
NOTE
It is the responsibility of the person who sells the system
of which the M3PSM will be a part to ensure that th
e
total system meets allowed limits of conducted and
radiated emissions.
NOTE
The handles provided on the fan tray and power supply
are for installation only; they are not designed to
support the full weight of the chassis, and should no
t
be used as carrying handles.
