Overview

This chapter describes the DEChub 900 MultiSwitch hub. It includes an overview of

the features, and it describes the hub power system and backplane capabilities.

The DEChub 900 MultiSwitch hub complements Digital’s DEChub 90 and DEChub

ONE family of products. The DEChub 900 MultiSwitch hub uses advanced hub

technology to provide complete backward compatibility with the DEChub 90 network

modules.

The DEChub 900 MultiSwitch hub with either DEChub 90 or DEChub 900 Multi-

Switch series network modules installed becomes an integral part of any distribution

subsystem within a structured wiring environment.

This hub is a high density hub that is capable of supporting multiple network technol-

ogies. A flexible channel architecture is used to support Ethernet, Token Ring, and

fiber distributed data interface (FDDI) technologies, as well as higher speed emerg-

ing technologies such as asynchronous transfer mode (ATM).

The DEChub 900 MultiSwitch uses industry standard Simple Network Management

Protocol (SNMP) and a network management station (NMS) with native SNMP to

manage the hub with in-band and out-of-band support.
