4. Connecting the LS-4500AF
4.1 Before Connection
Before connecting the cables, confirm that the power of all devices,
including the computer system and the LS-4500AF, is turned off.
For an IBM PC/AT or compatible in which a SCSI board has not been
installed, install a SCSI board as explained in the manual supplied with the
board.
When installing a SCSI board for the first time, be careful not to use the
same number as used for another purpose such as an I/O address or inter-
rupt number, or the graphic board DMA channel.
Note: Make sure that the PC is powered off before installing the SCSI
board.
