CHAPTER 2

NETWORK PLANNING AND CONFIGURATION

Before you attempt to install the Cabletron Systems EMME, review the
requirements outlined in this chapter. Also, refer to the operating
specifications and environmental requirements that are listed.

All conditions, guidelines, specifications and requirements included in
this chapter must be met to insure satisfactory performance of the EMME.
Failure to follow these guidelines will result in unsatisfactory network
performance.

2.1

NETWORK REQUIREMENTS

When connecting a network segment to the EMME, via a transceiver and
an AUI cable, you will need to make sure that the following requirements
are met:

•

The transceivers used to connect the EMME meet Ethernet Version 2
or IEEE 802.3 standards.

•

The AUI cables connecting the EMME to the transceivers on the
network match the transceiver type on the network segment, Ethernet
Version 1, Version 2, or IEEE 802.3 type cables, and do not exceed 50
meters in length.

2.2

EMME IN THE MULTI MEDIA ACCESS CENTER

The EMME is designed to be installed in the Cabletron Systems Multi
Media Access Center (MMAC). The MMAC-FNB (Flexible Network
Bus) hub series provides the platform for multiple separately repeated
Ethernet segments. The FNB backplane provides two additional buses for
Ethernet channels B and C. The MMAC Ethernet A channel, supports
Cabletron’s non-repeater Ethernet modules, while Ethernet channels B
and C support Cabletron’s family of repeater MIMs.
