1.2 DEChub 90
The DEChub 90 chassis is designed to support the communication needs of small to
mid-size work groups. Figure 1–1 displays the DEChub 90 with modules installed.
Built as an Ethernet-based backplane, the DEChub 90 chassis provides mounting,
power, and backplane ThinWire Ethernet connection to accommodate up to eight
half-height modules. These modules include repeaters, network access servers,
bridges, and wide area routers. Network management capability is provided by the
DECagent 90 and SNMP-based network management software.
Any DEChub 90 configuration that includes a DECbridge 90 or a DECrepeater
90FA network module can connect to the Ethernet backbone using the standard
attachment unit interface (AUI) connector on the bridge or repeater. Two DEChub
90 chassis can be interconnected using the BNC port to create a sixteen-slot hub,
which can operate and be managed as a single entity.
