1Connect the cable from the SCSI device to a VHDCI SCSI port on the FastStream VT 5300.

2Check the type of cable, cable length limit and number of devices recommended for the port. See Exhibit A-1.

Keep cable lengths as short as possible to ensure the highest signal quality and performance. These cable lengths include the wiring inside the devices.

3Set the IDs of the SCSI devices connected to the FastStream to a value other than 7.

Use a sequential ID starting at 0 for each device. The SCSI port has an internal factory setting ID of 7, typical for a SCSI initiator device.

4Terminate the SCSI bus after the last device. The FastStream VT 5300 is terminated internally.

Fibre Channel connections

The Fibre Channel port connects the FastStream VT 5300 into either a Fabric or Arbitrated Loop.

The FastStream VT 5300 uses optical SFP connectors and multimode fiber optic cable.

Make sure all cables are anchored securely at both ends with the proper connectors. Use the shortest possible cable length for best performance.
