Cabletron Systems MICROMMAC-22T, 42T manual MicroMMAC-T Overview

INTRODUCTION

describes how to install a TPIM and concludes with installation check-out instructions.

Chapter 4, Local Management, explains how to set up and use a management terminal and a modem to access Local Management.

Chapter 5, Troubleshooting, explains how to monitor the operation performance of the MicroMMAC-T using LANVIEW® LEDs and LCD’s. It also explains how to access POWER UP diagnostic test information.

1.2 MicroMMAC-T OVERVIEW

The MicroMMAC-T is an intelligent, stackable Multi-Media Access Center providing connectivity and SNMP management for up to 255 Token Ring users (Local Management for up to 120 Token Ring users) in remote office environments. The MicroMMAC-T can be used in conjunction with Cabletron’s STH HubSTACK series of stackable non-intelligent hubs.

Figure 1-2 illustrates a typical MicroMMAC-T configuration scenario. Attachable Bridge/Routing Interface Modules (BRIMs), incorporated as seamless entities within the MicroMMAC-T, provide connectivity not only to standard Token Rings but also to Ethernet, FDDI, ATM, and WAN environments, depending upon the BRIM types used.

Token Ring Port Interface Modules (TPIMs) attachable at the Ring In/Ring Out (RI/RO) ports provide connectivity and expanded trunk connections to a range of Token Ring media: Unshielded Twisted Pair (UTP), Shielded Twisted Pair (STP), and Fiber.

By installing Cabletron’s MicroSNAC daughterboard in the MicroMMAC-T, you can consolidate SNA/SDLC, BSC, LAN, and WAN connectivity into a single unit.

Telnet support provides easy access to Local Management tools from any TCP/IP based node on the network.

The MicroMMAC-T complies with the IEEE 802.5 standard and is fully IBM Token Ring compatible. The remainder of this chapter discusses MicroMMAC-T features in greater detail.
