CHAPTER 1 INTRODUCTION The MMAC-M8FNB™ 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 seven Media Interface Modules (MIM™), allowing up to 171 network connections depending on the Repeater/Management module and the MIMs that have been installed. This manual is an installation and reference guide.
INTRODUCTION Chapter 3, MMAC-M8FNB Setup, contains instructions for rack mounting your MMAC-M8FNB, inserting the fan tray, installing the power supply(ies), installing the security bars, and powering up the MMAC-M8FNB. 1.1.
INTRODUCTION modules into the MMAC-M8FNB, 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 Management software packages; these manuals include information about how to remotely manage the MMAC-M8FNB and the M8PSM-E and M8PSM-EDC power supply modules.
INTRODUCTION 1.4 By Internet mail: support@ctron.com By FAX: (603) 337-3075 By BBS: (603) 335-3358 (4 lines available) THE MMAC-M8FNB MULTI MEDIA ACCESS CENTER The Cabletron Systems MMAC-M8FNB is a complete modular approach to integrated networks. The MMAC-M8FNB 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).
INTRODUCTION A variety of IEEE 802.3, IEEE 802.5, and FDDI compliant media can be connected to the MMAC-M8FNB, 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-M8FNB, is compatible with all other MIMs installed in that unit. The MMAC-M8FNB provides complete network integration of a variety of media through a single source.
INTRODUCTION 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 power cycling (turn power switch off, then on again) to recover. A FAULT LED on the power supply modules indicates when an over current condition has occurred.
INTRODUCTION Any two matching power supply modules (i.e., two M8PSMs, two M8PSM-Es, or two M8PSM-EDCs) will use a current sharing scheme such that each power supply provides 50% of the required load (±5%, 5V output only) under all load conditions; if you have one M8PSM and one M8PSM-E installed, the M8PSM-E will supply 60% of the required power, and the M8PSM will supply the remaining 40%.
INTRODUCTION NOTE In a system in which two power supplies are installed and each is using more than 50% power, LED segments 5-9 will illuminate yellow, warning of the loss of redundancy.
INTRODUCTION Removable Fan Tray The MMAC-M8FNB 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. The fan tray is hot-swappable; however, the MMAC chassis should not be run for extended periods of time without the fans installed, as it will quickly overheat.

Installing the M8FNB into a Rack 7. Align the slots on each mounting bracket with the desired holes on the equipment rack. 8.
MMAC-M8FNB SETUP 3.2.2 Rack Mounting the Cable Tie Tray A cable tie tray is provided with the MMAC-M8FNB to support and organize cables connected to the unit. The tray is designed to be installed under the MMAC-M8FNB in the equipment rack. To mount the cable tray in a standard 19" equipment rack: 1. Slide the cable tie tray (Figure 3-2) into the rack. 2. Align the slots on each mounting bracket on the tray with the desired holes on the equipment rack. 3.
MMAC-M8FNB SETUP 3.2.3 Inserting the Fan Tray The MMAC-M8FNB is equipped with a removable fan tray that allows for easy periodic cleaning and/or replacement if a problem occurs with fan operation. To insert the fan tray in the MMAC-M8FNB: 1. Hold the fan tray as shown in Figure 3-3 (following page) and align the slotted paths on the tray with the slot guides on the left and right walls of the MMAC-M8FNB chassis. 2.

MMAC-M8FNB SETUP The MMAC-M8FNB power supply modules are installed in the slots in the rear of the MMAC-M8FNB chassis (Figure 3-4). If you intend to install a single power supply module, the single module can be installed in either the left or the right slot; be sure to leave the empty power supply slot covered. Install the power supply module(s) into your MMAC-M8FNB as follows: 1. Unpack the power supply module by removing it from the shipping box and sliding the two foam end caps off the unit.
MMAC-M8FNB SETUP 4. Slide the power supply into the appropriate slot of the MMAC-M8FNB as follows: a. Hold the module by the two handles on its front panel. b. Align the power supply module with the slotted paths on the top and bottom of the opening. c. Ensuring that the power supply is inserted into the slotted paths, carefully slide the module forward until the module is connected to the backplane.
MMAC-M8FNB SETUP 3.2.5 Installing the Security Bars The MMAC-M8FNB is equipped with security bars to prevent unauthorized access to the hub and its installed modules. Two security bars have been provided: one to cover the top row of knurled knobs securing the modules to the chassis, and one to cover the bottom row of knobs. To attach the security bars to the chassis: 1. Install all MIMs in the M8FNB hub, as desired; be sure to install panels over any empty slots. 2.
MMAC-M8FNB SETUP Install the security bars over the knurled knobs on the modules; align the screws in the security bars with the holes in the chassis as indicated, and secure.
MMAC-M8FNB SETUP 3. For any installed M8PSM-EDC power supplies: Verify that the DC power source is off or disconnected before making power connections to the M8PSM-EDC power supply. a. To connect to a positive 48 volt power source: 1.) Connect the ground terminal on the M8PSM-EDC to appropriate earth ground. 2.) Connect the positive 48 volt return lead to the negative terminal on the M8PSM-EDC. 3.) Connect the positive 48 volt lead to the positive terminal on the M8PSM-EDC. 4.
MMAC-M8FNB SETUP 6.) Move the power switch on each power supply to the ON position. 4. Make sure that the Power OK LED is lit. NOTE If you have not yet installed a repeater/management module and/or a MIM or MIMs, the Fault LED may illuminate when the power switch is turned on. If this happens, turn the power supplies off, install the MIMs, then turn the power supplies back on (remember, power cycling is required once the Fault LED has been lit). At that time, the green (Power OK) LED should illuminate.
