  • Page 11: Tape Array Overview

    Chapter Tape Array Overview Introducing the Array The Compaq TA1000 Tape Drive Array™ supports up to 10 Compaq hot-pluggable tape drives. It supports Wide-Ultra and Wide-Ultra2 SCSI protocols. The internal bus supports only low voltage differential (LVD) drives. The external bus (the array to the host controller bus) supports either Wide-Ultra2 (LVD) or Wide-Ultra single-ended (SE) SCSI protocols.
  • Page 12: Tape Array Features

    A dual-bus Ultra2 I/O module A hot-pluggable tape drive in each bay The TA1000 Tape Drive Array supports up to ten 1.6-inch, Compaq hot- pluggable tape drives. The array is a rack-mountable device that requires a 3U vertical opening (5.25-inches) where a “U” is 1.75 inches.
  • Page 13: Scsi Buses

    Tape Array Overview 1-3 The hot-pluggable tape array elements are replaceable without stopping SCSI bus data transfers. The TA1000 Tape Drive Array is designed to support only Compaq hot-pluggable tape drives.

  • Page 16: Attaching The Mounting Brackets

    Attaching the Mounting Brackets Attach the two mounting brackets. IMPORTANT: Some Compaq racks use a square-hole rail design, while others use a round-hole rail design. Where indicated, follow the steps for each rack type. 1. For square-hole racks only: Install two alignment clips 1 over the round tabs on the front of each mounting bracket.
  • Page 17 2-4 Compaq TA1000 Tape Drive Array Reference Guide 3. If necessary, loosen the three screws in the middle of the mounting bracket to adjust the length of the bracket to fit your rack. 4. For square-hole racks only: Position the left mounting bracket 1 just behind the front vertical rail, aligning the middle two mounting bracket holes with the rail holes previously marked using the template.
  • Page 18 Tape Array Installation 2-5 5. For round-hole racks only: Extend the mounting bracket through the rear vertical rail holes. Be sure that the mounting bracket fingers are inserted into the corresponding vertical inner rail holes. Figure 2-4. Round-hole rack bracket alignment IMPORTANT: The mounting bracket must be parallel from front to rear before you secure it to the rack.
  • Page 19 2-6 Compaq TA1000 Tape Drive Array Reference Guide 6. Secure the bracket to the rear vertical rail using two washers and two Kep nuts 1. 7. Secure the mounting bracket to the front vertical rail using two pan head SEMS screws 2 (10-32 x 5/8 in).
