2.0 INTRODUCTION

SECTION II

INSTALLATION AND OPERATION

Section II describes unpacking, inspecting, installing, cabling, adjusting, and operating the Model 9600B/9650B Tape Drive.

2.1 UNPACKING

WARNING

The Model 9600B Tape Drive weighs 110 pounds. Use safe lifting practices to remove the drive from the container.

The Model 9600B and 9650B Tape Drives are shipped cushioned by polyethylene foam supports in a heavy-weight cardboard container. Place the shipping container on a flat, horizontal, dry, non-slip surface. Carefully cut the binding straps, and remove the top lid. Remove the cardboard sides of the shipping container. The Drive can now be conveniently lifted from the shipping container. Set the Drive on a flat, horizontal surface. Save the following items: Slide Rails, AC Power Cord, alternate voltage Fuse Kit, Hardware (two Shipping Retainer Brackets, Rack-Latch Angle Bracket, . screws, etc.) and 9600B/9650B Manual. Retain the shipping container, polyethylene wrap, and foam supports for possible future shipment.

Tape Drives shipped in racks may be held in place by the two Shipping Retainer Brackets mentioned above (Figure 2-1). These Brackets should be removed after the Rack is put in its final location at the installation site, and the Rack-Latch Angle Bracket (also mentioned above) must be installed in place of the left Retainer Bracket. This Bracket comprises the Catch (Figure 2-1) for the Retainer Latch located just inside the Front Panel.

2.2 INSPECTION

Inspect the drive for shipping damage such as scratches, dents, or cracks in the frame. On the Dust Cover (top of Drive), turn the two holding fasteners 1/4 turn counterclockwise and open the. dust cover. With the Cover Support Bar (Figure 2-2), latch the Dust Cover in Maintenance Position. Check for loose or missing parts, and foreign material. Open the Tape Path Cover and verify that all parts/areas of the tape path are clean. Remove the PCBA Cover and verify that all PC Boards (Figure 2-4) are seated properly. Reinstall PCBA Cover.
