3.4 Bridges
Network Modules 3–39
3.4.1 DECbridge 90
The DECbridge 90 connects to the backbone using ThinWire Ethernet or AUI
transceiver cable. The AUI can support various transmission media such as coaxial
and fiber optic cables by use of an optional MAU. Figure 3–13 shows the DECbridge
90 network module.
You can be connected to either the ThinWire or the AUI, but not both
simultaneously. The active connection is determined by a slide switch on the front of
the module. It also includes a ThinWire 10Base2 port connector (ThinWire BNC) on
the side panel (available when installed in the stacking unit or standalone).
NOTE
When used in the hub or stack, the bridge requires a proxy agent. Also,
when used in the DEChub 90 the bridge must be installed in slot 7 or 8.
