Grounding requirements
A safety ground must be provided by the site AC power system. The green wire (or green wire with yellow stripe) in the AC power cord provides the safety ground connection between the power supply and the site AC power system. The site AC power system must provide the safety ground to earth ground connection.
All site AC power connection points, including convenience outlets for test equipment, must be maintained at the same safety ground potential.
Interface requirements
An important part of site preparation is planning the layout and routing of I/O cables. All drives and other SCSI devices are connected together and to the host with an I/O cable. TheSCSI bus can have up to 16 devices attached to it as shown inFigure 7.TheI/O cabling scheme used is called a daisy chain. Each end of the SCSI bus must be terminated.
