3.3Power and SCSI Cable Connection Procedures

This section contains the power and SCSI cabling procedures for a single or multiple Device Expansion Shelf subsystem installation. Each procedure de- scribes how to connect the Controller Shelf to the Device Expansion Shelve(s), the host system, the UPS, and the maintenance PC. Your Controller and Device Expansion shelf shipment contains all of the power, serial control, and SCSI data cables required to connect and configure your system. These cables, along with two Trilink adapter connectors allow you to create a single or multiple storage subsystem as shown in Figures 3–1 through 3–4.

The section is divided into four procedures that describe how to connect a single or multiple-shelf configuration. Each is supported by a wiring diagram and is in- dependent of the other three. Proceed to the procedure that applies to the number of Device Expansion Shelves you are connecting to the Controller Shelf.

NOTE

All four cabling procedures describe how to con- nect your subsystem to a single host via the host I/O module 0 connector on the Controller Shelf. The procedures are the same for host I/O module 1. Also, no connections are shown to the Host Out connector on the I/O module. This connector is electrically the same as Host In and is used for mid-bus connections in a multiple-host configura- tion.
