Chapter 2 – Installation
This chapter describes how to install the XVME-977 Hard Disk/Floppy Disk Module
into the VMEbus backplane. It also provides information on connecting the XVME-977
to Xycom’s XVME-65x VMEbus PC/AT processor modules.
Installing into a VMEbus Card Cage
The XVME-977 occupies only one double-high VMEbus slot, and fits into any standard
6U VMEbus card cage. Like all of Xycom’s modules, the XVME-977 is designed to
comply with all electrical VMEbus backplane specifications. This module only draws
current from the +5 volt power supply.
Caution
Never attempt to install or remove any boards before turning
off power to the bus and all related external power supplies.
Before installing a module, determine and verify all connec-
tions to external devices or power supplies.
Figure Chapter 2 -1 depicts installation of the XVME-977 board.
