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,

, 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.
