MicroMMAC Installation Guide Page 1-3

Chapter 1: Introduction

1.5 MicroMMAC FEATURES

Repeater Functionality

The MicroMMAC fully conforms to the IEEE 802.3 Repeater, AUI, and

10BASE-T specifications, and provides the flexibility to connect networks using IEEE 802.3, Ethernet Version 1 or Version 2 equipment.

The MicroMMAC transmits retimed data packets, regenerates the preamble, extends fragments, and arbitrates collisions.

The MicroMMAC automatically partitions problem segments, and reconnects repaired segments to the network. This feature minimizes the impact on network operation resulting from a problem on one segment by isolating the problem segment. Only devices on the problem segment are affected. When the problem is solved, the MicroMMAC automatically reconnects the isolated segment to the network.

Polarity Detection and Correction

Each twisted pair port on the MicroMMAC incorporates a Polarity

Detection and Correction feature. This feature allows the MicroMMAC to pass data regardless of the polarity of the twisted pair segment’s receive link. Cabletron Systems does not recommend operating in this condition.

If you discover this condition, remove the segment from the network and wire it correctly. This reduces the potential for problems in the future if equipment changes are made.

Local Management

Local Management allows you to manage the MicroMMAC and all its attached segments. It also provides full packet and error statistics for the entire stack, individual device, or individual port. You access Local

Management by attaching a DEC VT320 terminal or a PC using VT320 emulation software to the MicroMMAC’s RJ45 COM 2 port. Refer to the

MicroMMAC Local Management User’s Guide for instructions on how to use Local Management.

LANVIEW LED

Cabletron Systems LANVIEW status monitoring and diagnostics system is a troubleshooting tool that helps diagnose power failures, collisions, cable faults, and link problems. LANVIEW LEDs are conveniently located on the MicroMMAC front panel.

Page 1-4 MicroMMAC Installation Guide

MicroMMAC Features

LCD

The MicroMMAC is equipped with an LCD that provides information about the MicroMMAC such as power up diagnostics, firmware revisions,

MAC and IP addresses, and error alerts.

Reset Button

The Reset button lets you re-boot and initialize the processor.

Intelligence

The MicroMMAC is equipped with an advanced Intel i960 microprocessor to provide a scalable RISC-based architecture.

Management Information Base (MIB) Support

The MicroMMAC provides IETF MIB support which includes the following:

• Remote Monitoring MIB (RMON)

• Bridge MIB

• MIBII

Serial Connections

The MicroMMAC provides two RJ45 ports (COM 1 and COM 2) for serial connections. The COM ports allow access to Local Management by locally connecting a DEC VT220 or VT320 terminal, or a PC using VT emulation software. The COM ports also provide a connection for an

Uninterruptible Power Supply (UPS).

DLM

Cabletron Systems Distributed LAN Monitor (DLM) is a software option for the MicroMMAC. DLM provides a method to locally poll and monitor any Simple Network Management Protocol (SNMP) or Internet Protocol

(IP) device using a remote management application.

MicroMMAC Installation Guide Page 1-5

Chapter 1: Introduction

•

•

FLASH EEPROMs

The MicroMMAC uses FLASH Electrically Erasable Programmable

Read Only Memory (EEPROM) which allows you to download new and updated firmware using SPECTRUM Element Manager for Windows or any device using BOOTP or tftp protocols.

The MicroMMAC supports the following download applications:

Standard Download - the MicroMMAC automatically becomes disabled while the new firmware image loads directly into Local

Dynamic Random Access Memory (LDRAM). You can not perform a

Standard Download through a BRIM interface.

Runtime Download - the MicroMMAC continues to operate without interruption while you download the new firmware image directly into

FLASH memory. The original firmware image in LDRAM continues to run until the MicroMMAC is reset. You can perform a Runtime

Download through any network port, including the BRIM.

1.6 STACKABLE CAPABILITIES

The MicroMMAC can be stacked together with Cabletron Systems SEH series of non-intelligent hubs. You can stack as many as four non-intelligent hubs with one MicroMMAC. The MicroMMAC provides complete management for the stack, including full packet and error statistics for the entire stack, individual device, or individual port. You can also add or remove hubs from the stack without having to power down.

Stackable configurations let you maintain only one IEEE repeater hop while providing up to 130 Ethernet ports. The rear panel HubSTACK

Interconnect Bus Out port of the MicroMMAC lets you daisy chain hubs together using the HubSTACK Interconnect cable. Figure 1-1 shows a typical stackable configuration.

!

C AUT IO N

DO NOT change the state of Switch 6 unless

–you have a station acting as a BOOTP server, and a tftp server that contains the MicroMMAC image file. The BOOTP server and the tftp server could be different servers.

–you intend to set up a station to act as a BOOTP server for the

MicroMMAC.

After changing the state of this switch, and repowering the device, the

MicroMMAC requests a new image until it either receives a new image, or you reset the MicroMMAC again by using the Reset button on the front panel.

Reset the MicroMMAC a second time. The device attempts to locate a BOOTP server again. However, the BOOTP request times out after about one minute, and the MicroMMAC boots from FLASH memory.

• Switch 7 - Cabletron Systems use only.

• Switch 8 - Password Defaults. Changing the state of this switch clears user-entered passwords stored in NVRAM, and restores default passwords. Once you reset the MicroMMAC, you can use the defaults or re-enter your passwords.

4.1.4 Connecting a 10BASE-F Segment to an EPIM-F1

!

C AUT IO N

When connecting a fiber optic link segment with SMA 906 connectors to an EPIM-F1 with SMA ports, make sure each connector uses half alignment, NOT full alignment, sleeves. A full alignment sleeve damages the receive port. SMA 905 connectors do not need alignment sleeves.

Each fiber optic link consists of two strands of fiber optic cabling: the transmit (TX) and the receive (RX). The transmit strand from a module port connects to the receive port of a fiber optic Ethernet device at the other end of the segment. The receive strand of the applicable port on the module connects to the transmit port of the fiber optic Ethernet device.

Page 4-6 MicroMMAC Installation Guide

Connecting the MicroMMAC to the Network

Cabletron Systems recommends labeling fiber optic cables to indicate receive and transmit ends. Many cables are prelabeled, providing matching labels or tapes at both ends of each strand of cable.

1. Remove the protective plastic covers from the fiber optic ports on the applicable port on the module, and from the ends of the connectors on each fiber strand.

!

C AUT IO N

Do not touch the ends of the fiber optic strands, and do not let the ends come in contact with dust, dirt, or other contaminants.

Contamination of cable ends causes problems in data transmissions. If necessary, clean contaminated cable ends using alcohol and a soft, clean, lint-free cloth.

2. Attach one fiber to the receive port (RX) on the EPIM-F1. Insert the

SMA connector into the port. Turn the connector clockwise until the connector will no longer turn easily. Do not overtighten the connector.

3. Attach the other fiber of the pair to the applicable transmit port on the module. Use the same procedure for insertion of the ST connector.

MicroMMAC Installation Guide Page 4-7

Chapter 4: Connecting to the Network

4. At the other end of the fiber optic cable, attach the fiber pair to the transmit and receive ports of the device.

If link indicators are present for the fiber optic connection, check that they are ON. If an indicator is present but not ON, that port does not have a valid link. Perform each of the following steps until you reach a resolution of the problem and achieve a link.

• Check that the device at the other end of the link is ON.

• Verify proper cross-over of the fiber strands. Try swapping the transmit and receive connections at only one end of the link.

• Verify that the fiber connection meets the dB loss specifications outlined in Appendix C, Network Planning and Configuration.

If you are still unable to establish a link, attempt to make the connection between the devices with another fiber optic cable. If this is unsuccessful, contact Cabletron Systems Technical Support.

APPENDIX C

NETWORK PLANNING AND CONFIGURATION

This appendix contains general network guidelines. Before attempting to install the MicroMMAC or any additional EPIMs or BRIMs, review the requirements and specifications outlined in this appendix.

!

C AUT IO N

Your network installation must meet the conditions, guidelines, specifications, and requirements included in this appendix to ensure satisfactory performance of this equipment. Failure to follow these guidelines may produce poor network performance.

C.1 NETWORK CABLE REQUIREMENTS

The network ports of the MicroMMAC support 10BASE-T Shielded

Twisted Pair (STP) or Unshielded Twisted Pair (UTP) cabling.

EPIMs support UTP, STP, multimode fiber optic, single mode fiber optic,

AUI, or 10BASE2 thin coaxial cabling. The rear panel Interconnect Bus port supports Cabletron Systems HubSTACK Interconnect cables for stackable applications.

Take care in planning and preparing the network cabling and connections.

The quality of the connections and the length of cables are critical factors in determining the reliability of the network. The following sections describe requirements for each media type.

C.1.1 HubSTACK Interconnect Cable

Attach the MicroMMAC to modules in the stack with the HubSTACK

Interconnect bus cables available only from Cabletron Systems. Refer to

Chapter 1 for cable part numbers.

The rear panel of the MicroMMAC has an Interconnect Bus Out port

(male connector) to stack SEH non-intelligent hubs together. One

MicroMMAC supports a stack of up to four SEH non-intelligent hubs.

MicroMMAC Installation Guide Page C-1

Appendix C: Network Planning and Configuration

C.1.2 10BASE-T UTP and STP Cable

The devices and 10BASE-T twisted pair segments connected to the

MicroMMAC and EPIM-T must meet the IEEE 802.3 specifications listed below:

Length

The IEEE 802.3 10BASE-T standard requires that 10BASE-T devices transmit over a 100 meter (328 foot) link using 22-24 AWG unshielded twisted pair wire. However, cable quality largely determines maximum link length. With high quality, low attenuation cable, link lengths of up to

200 meters are achievable. Cable delay limits maximum link length to

200 meters, regardless of the cable type. Cabletron Systems does not recommend UTP cable lengths of more than 100 meters.

NOTE

Losses introduced by connections at punch-down blocks and other equipment reduce total segment length. For each connector or patch panel in the link, subtract 12 meters from the total length of your cable.

Insertion Loss

The maximum insertion loss allowed for a 10BASE-T link is 11.5 dB between frequencies of 5.0 and 10 MHz. This includes the attenuation of the cables, connectors, patch panels, and reflection losses due to impedance mismatches in the link segment.

Impedance

Cabletron Systems 10BASE-T products work on twisted pair cable with

75 to 165 ohms impedance. Unshielded twisted pair cables typically have an impedance of between 85 to 110 ohms.

Shielded twisted pair cables, such as IBM Type 1 cable, are also used. The impedance of IBM Type 1 cable is typically 150 ohms. Higher impedance increases signal reflection, but because the cable is shielded, signal reflection has little effect on the quality of the received signal due to the lack of crosstalk between the shielded cable pairs.

Network Cable Requirements

Jitter

Intersymbol interference and reflections can cause jitter in the bit cell timing, resulting in data errors. A 10BASE-T link must not generate more than 5.0 ns of jitter. If the cable meets the impedance requirements for a

10BASE-T link, jitter should not be a concern.

Delay

The maximum propagation delay of a 10BASE-T link segment must not exceed 1000 ns This 1000 ns maximum delay limits the maximum link segment length to no greater than 200 meters.

Crosstalk

Signal coupling between different cable pairs within a multi-pair cable bundle causes crosstalk. 10BASE-T transceiver design alleviates concerns about crosstalk, provided the cable meets all other requirements.

Noise

Crosstalk or externally induced impulses can cause noise. Impulse noise may cause data errors if the impulses occur at very specific times during data transmission. Generally, noise is not a concern. If noise-related data errors are suspected, it may be necessary to either reroute the cable or eliminate the source of the impulse noise.

Temperature

Multi-pair PVC 24 AWG wires typically have an attenuation of approximately 8 to 10 dB/100 meters at 20

°

C (68

°

F). The attenuation of

PVC insulated cable varies significantly with temperature. At temperatures greater than 40

°

C (104

°

F), Cabletron Systems recommends the use of plenum-rated cables to ensure that cable attenuation remains within specification.

The maximum allowable fiber optic cable length is 2 km (2187.2 yards). However, IEEE 802.3

FOIRL specifications specify a maximum of 1 km (1093.6 yards).

Attenuation

Test the fiber optic cable with a fiber optic attenuation test set adjusted for an 850 nm wavelength. This test verifies that the signal loss in a cable is within an acceptable level. Table C-1 shows the attenuation for each multimode cable type.

Fiber Optic Budget and Propagation Delay

When determining the maximum fiber optic cable length to incorporate fiber runs into the network, calculate and consider the fiber optic budget

(a total loss of 10.0 dB or less is permissible between stations) and total network propagation delay.

To determine the fiber optic budget, combine the optical loss due to the fiber optic cable, in-line splices, and fiber optic connectors. Typical loss for a splice and connector (together) equals 1 dB or less.

Propagation delay is the amount of time it takes data to travel from the sending device to the receiving device. Total propagation delay allowed for the entire network is 25.6

µ s in one direction (51.2

µ s round trip). If the total propagation delay between any two nodes on the network exceeds 25.6

µ s, then bridges must be used.

However, IEEE 802.3 FOIRL specifications specify a maximum of 1 km (1093.6 yards).

Attenuation

Test the fiber optic cable with a fiber optic attenuation test set adjusted for an 1300 nm wavelength. This test verifies that the signal loss in a cable falls within the acceptable level of 10.0 dB or less for any given single mode fiber optic link.

Fiber Optic Budget and Propagation Delay

When determining the maximum fiber optic cable length to incorporate fiber runs into the network, calculate and consider the fiber optic budget

(a total loss of 10.0 dB or less is permissible between stations) and total network propagation delay.

To determine the fiber optic budget, combine the optical loss due to the fiber optic cable, in-line splices, and fiber optic connectors. Typical loss for a splice and connector (together) equals 1 dB or less.

C.1.5 10BASE2 Thin Coaxial Cable

The following specifications show 10BASE2 thin coaxial cable requirements for the EPIM-C:

Cable Type

50 ohm RG-58A/U type coaxial cable must be used when making up a

10BASE2 thin coaxial cable segment.

Length

The 10BASE2 thin coaxial cable segment must be no longer than 185 meters (203.5 yards).

Terminators

Terminate each end of a 10BASE2 thin coaxial cable segment.

Connectors

A maximum of 29 T-connectors may be used throughout the length of cable segment for host connections. If an excessive number of barrel connectors are used within the cable segment, such as finished wall plates with BNC feed-throughs, then a reduced number of host connections may be required. For special network design, contact Cabletron Systems

Technical Support.

Grounding

For safety, ground only one end of a 10BASE2 thin coaxial cable segment. Do NOT connect EPIM BNC ports to earth ground.

Connecting a 10BASE2 thin coaxial cable segment to earth ground at more than one point could produce dangerous ground currents.
