IBM 4690 manual Attaching the SCSI and Power Cables, Completing the Installation

Note: You can also mount the drive in a 5.25-inch (1.6-inch high) bay using the 5.25-inch mounting kit provided. When you attach the brackets to the sides of the 3.5-inch tape drive, you increase the width and height of the drive. The installation instructions are located on the mounting kit packaging.

2.Remove the cover plate from the bay selected. Slide the drive partially into the bay. Align the drive-bay screw holes with the threaded holes in the drive housing (or bracket, if applicable).

3.Use the screws provided to secure the drive in the bay. Usually two screws are used on each side. Some installations use the screw holes on the bottom (circuit board side) of the drive. Using the wrong size screws can damage the drive. Do not overtighten the screws. Check to ensure that the drive is securely mounted.

Step 5. Attaching the SCSI and Power Cables

1.Locate the SCSI and power connectors. The tape drive connectors are: v SCSI connector

vSCSI connector - pin 1

vPower connector

2.Locate the SCSI bus cable (usually a 50-pin ribbon cable). The SCSI bus adapter can be on the Store Controller system board or on an adapter installed in an expansion slot. If your Store Controller has a 68-pin cable, you need a 16-bit to 8-bit SCSI internal converter (IBM part number 32G3925 or equivalent).

3.There can be up to seven connectors on the cable from the SCSI bus adapter. Locate an available SCSI connector and plug it into the tape drive. Ensure that line 1 of the SCSI cable (usually color coded) aligns with pin 1 of the SCSI connector.

4.Locate an available power cable and connect it to the 4-pin power connector on the tape drive. If all power cables are in use, purchase a dc Y-connector at your computer dealer or electronics store. The power cable connector is keyed and ®ts properly only one way. Do not force it. If it does not attach easily, turn the connector around and try it again.

Step 6. Completing the Installation

1.Be sure that the power and interface connectors are securely attached.

2.Be sure that the cables are neatly routed. They must not: v Get in the way when the cover is replaced

vImpede the power supply fan blade

vBlock air ¯ow paths

3.Replace the Store Controller cover and secure it in place.

4.Reconnect the ac power cord and cables. Turn on all attached devices; then turn on the Store Controller.

Installing the External SCSI Drive

This section provides instructions for installing the external SCSI tape drive. The external SCSI model is essentially the internal SCSI model in a self-contained enclosure.
