Step 6: Plug one end of the internal SCSI cable into the host adapter's internal SCSI connector. s If you purchased your host adapter in an Adaptec kit, an internal SCSI cable that allows you to connect up to two internal SCSI devices is included. If you are connecting more than two internal SCSI devices, you must obtain a 50-pin internal SCSI cable with enough connectors to accommodate all of your devices. s Make sure the colored stripe on one side of the cable is aligned with pin-1 of the host adapter's connector. Pin-1 of the connector is usually designated by a small triangle (v), or a "1" on the connector.
