2 Cabling Storage Devices and Setting SCSI Addresses

Switches 3, 4 and 6 determine the SCSI address setting for each shelf in the hot- swap subsystem. Table 2-2 describes the settings and the shelf’s SCSI address.

Cabling Configurations

The storage system can be reconfigured by changing the internal cabling configuration or changing the switch settings on the cages. This section describes the external, the internal default, and some (but not all possible) internal cabling configurations and switch settings for both the hot-swap cages and the SCSI device shelves.

External Cabling

The storage system uses external, SCSI cables (not included) to communicate with the host system. Cables used with this product must be properly shielded to comply with regulatory requirements. The connection(s) at the back of the storage system are 68-pin, high-density connectors. Using the appropriate external SCSI cable, the storage system can be connected to the host system by using a variety of connectors (see Table 2-3 for the appropriate cable). The
