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.

1.3 GETTING HELP

have any questions, comments, or suggestions related to this manual,

contact Cabletron Systems Technical Support. Before calling, please

have the following information ready:

• The product type (MMAC-M5FNB), and the product serial

number.The serial number is located on the front panel of the

MMAC, and the product type is on the fan tray label.

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.
