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,

Page 1-3

INTRODUCTION

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.

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.

are for installation only; they are not designed to
support the full weight of the chassis, and should no
be used as carrying handles.

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.
