2.5 INSTALLING THE XVME-678/688 INTO A BACKPLANE
This section provides the information necessary to install the XVME-678/688
PCI
AT Processor Module
into the VMEbus backplane.
Xycom modules are designed to comply with all physical and electrical VMEbus backplane specifications.
The XVME-678/688 is a double-high, single-board VMEbus module. As such, it requires one slot with
either just the PI VMEbus backplane, or with both the PI and P2 backplanes.
The XVME-955 Hard Disk/Floppy Disk Module, available from Xycom, is ideally suited for use with
the
XVME-678/688.
It combines a high-capacity 3.5" IDE drive and a 3.5" 1.44 Mbyte micro-floppy into
a unit that occupies only two double-high VMEbus slots. Ask your Xycom representative for details.
WARNING
Do not install or remove any boards before turning off the power to the bus
and all related external power supplies.
1. Disconnect all power supplies to the backplane and/or terminal.
2. Make sure the backplane PI and P2 connectors are accessible.
3. Verify all jumper settings.
4. If using the Intel80387SX math co-processor, install it in socket U7 of the XVME-678/688. Refer
to Section 2.8 for more detailed diagrams.
5. Position SWI switch 6 to closed to enable the on-board battery.
