SCSI Cable Connectors

To identify the various SCSI cables required 64-Bit/66 MHz Single Channel

Wide Ultra3 SCSI Adapter installation in the various configurations of

Compaq servers, see Figure 1-2.

Keep these characteristics of SCSI cables in mind:

■

External standard Wide SCSI cables have a round wire with securable

connectors, and the connector heads are smaller than 68-pin external

wide SCSI connector heads.

■

Internal SCSI cables have a flat ribbon cable with push-on connectors.

■

Internal 68-pin wide SCSI ribbon cables (Wide Ultra2 SCSI,

Wide-Ultra SCSI-3, Fast-Wide SCSI-2) are narrower than 50-pin SCSI

(Fast-SCSI-2) cables.

■

Compaq SCSI cables are keyed so they cannot be installed incorrectly.
