Description
===========
The DEC FDDIcontroller/Q-bus allows the transmission of data from Q-bus
based systems to a 100Mb/s FDDI network. Depending on the model and the
topology, the controller can serve as either a SAS (Single Attachment
Station) or a DAS (Dual Attachment Station) connection to the network . A
SAS connection connects through a fiber optic cable to an FDDI-compliant
concentrator. A DAS connection connects directly to the FDDI network.
Features
========
Power on selftest LEDs
OpenVMS VAX operating system Version 5.5-2 or greater or DEC
FDDIcontroller/Q-bus driver files installed on the system
The DEC LAN Device Driver Kit for OpenVMS VAX, Version 1.0 (P/N
QA-OPAAA) contains the DEC FDDIcontroller/Q-bus driver files.
Flash memory
CSR address switches
Optical bypass connector RJ12 (The optical bypass relay feature
on the controller maintains FDDI dual ring integrity if the controller
breaks or is powered down. The optical bypass connector is available
only on the DAS multimode versions.)
MDM Diagnostics compatible

*WARNING: *Some fiber optic equipment can emit laser light that can
injure your eyes. Never look into an optical fiber or connector port.
Always assume the cable is connected to a light source.
