Cabletron Systems 42T User Manual

 

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

Chapter 4, 

 

, 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.

 

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.
