Chapter 2 - Installation
Introduction
There are three major steps to the installation of a DLT LibraryXpress System: mechanical
installation, cabling and configuration.
Mechanical installation consists of:
•
assembling the XpressChannel (the two-module system comes factory assembled),
•
installing the module mounting slides in the rack,
•
installing the XpressChannel in the rack, and
•
installing the modules in the rack.
Cabling consists of interconnecting the slave modules with the Global control Module,
connecting the Global Control Module to the XpressChannel motor, connecting the slave
module drive SCSI busses to host SCSI interfaces, connecting the Global Control Module to a
host SCSI interface, and terminating the busses properly.
Configuration consists of using the Configure Menu to customize the configuration options to
your particular application.
The remainder of this chapter describes each of these steps.
Planning Your Installation
The DLT LibraryXpress System is intended to be mounted in a standard 19-inch
EIA/RETMA equipment rack with a depth of 24 to 30 inches. Each of the modules is shipped
with two rack slides installed.
Every DLT LibraryXpress System includes:
•
one Global Control Module,
•
one expandable XpressChannel cartridge elevator, and
•
one or more slave modules (up to eight).
The Global Control Module has 16 slots and no drives. The slave modules can be Base
Modules (10 slots plus one or two drives), or Capacity Modules (16 slots, no drives), in any
useful combination. (All slots and no drives is not a useful combination.) Each module
occupies seven inches (4 units) of rack space.
The XpressChannel is composed of a motor drive assembly plus sections of track whose
combined length is equal to the combined heights of the Global Control Module plus the slave
modules. An extension section is needed for installation with each module.
