Removing and Installing Boards
This section describes how to remove and install VME option boards.
WARNING: Unqualified personnel attempting to remove, install, or
service internal components or options in AViiON 5000, 6000,
7000, and 8000 series systems risk both personal injury and
damage to the system. Data General Corporation supports
the maintenance and expansion of these systems by qualified
Data General personnel only. Service by other than
Data General personnel may void product warranties. For
more information regarding Data General warranties, refer to
your Data General sales and field engineering contracts.
NOTE: The instructions in this chapter cover all standard VME option boards
supported by your AViiON system, including the Model 7411–KA VAC/16
board. Data General Model 7411–K VAC/16 boards, however, include
nonstandard air dams and junction box assemblies. For instructions on
removing and installing Model 7411–K option boards, refer to Appendix D,
“Special Instructions for Model-Specific VME Hardware.”
CAUTION: If your system has the old EMI/air dam system, you must install an
EMI/Air Dam Upgrade Kit as described in the previous section before
installing new or replacement VME controller boards with the new
EMI/air dams.
