This arrangement requires:

•A network switch

•A network interface card (NIC) in the PC

•A SCSI HBA card in the PC

•A SCSI cable that fits your HBA card and has a VHDCI connector to fit the VTrak SCSI channel

VTrak’s SCSI connectors are bi-directional. However, the internal termination feature works only on the “Out” connector. Internal termination is set to “Automatic” by default.

Connect the PC’s standard NIC and VTrak’s Management Port to your network switch to establish the management path.

Connect a SCSI cable to the PC’s SCSI HBA card and one of the VTrak’s SCSI channels. To use the internal termination feature, attach the SCSI cable to the “In” connector. An external terminator is not required for this arrangement.

If you plan to connect multiple VTraks on a SCSI chain, connect the other side of the same SCSI channel on the first VTrak to a SCSI channel on the second VTrak.

See “SCSI Channel Settings” on page 95 or “Channel Settings” on page 198 for more information about the internal termination feature.
