Welcome to the NetSight Element Manager for the MicroMMAC-T User’s Guide. We have designed this guide to serve as a simple reference for using NetSight Element Manager for the MicroMMAC-22T/24T and MicroMMAC-42T/44T.

The MicroMMAC-22T/24T™and MicroMMAC-42T/44T™are intelligent Token Ring hubs that provide front panel ports for network connections, a rear-panel HubSTACK™ Interconnect Bus port for stackable connections, and a rear-panel port for one optional Bridge Router Interface Module™ (BRIM®) that provides the MicroMMAC-T™with bridging and routing capability. All the devices fully conform to the IEEE 802.5 standards, and provide the flexibility to connect networks using a variety of media via 12 or 24 active RJ45 ports for STP or UTP lobe connections. All of the models are functionally identical; the only difference among them is the configuration of the front panel ports: the MicroMMAC-22T has 12 built-in active UTP RJ45 lobe ports; the MicroMMAC-24T has 24 built-in active UTP RJ45 lobe ports; the MicroMMAC-42T has 12 built-in active STP RJ45 lobe ports; and the MicroMMAC-44T has 24 built-in active STP RJ45 lobe ports. Using the MicroMMAC-T’s external HubSTACK-IN and HubSTACK-OUT connections on the rear of the unit, you can stack as many as four of Cabletron’s STH Series non-intelligent Token Ring hubs with one MicroMMAC-T, and the entire stack can be managed by the MicroMMAC-T as a single Token Ring. This configuration allows you to expand the connectivity of the MicroMMAC-T to up to 120 ports.

NOTE

Since the devices covered in this User’s Guide are functionally identical, they will be jointly referred to throughout the text as the MicroMMAC-T. Likewise, since the only differences in the windows for each device will be the device name (MicroMMAC-24T, MicroMMAC-44T, etc.) and the number of ports displayed, only the MicroMMAC-24T windows will be shown.
