Chapter 2 - Installation

29

Note: If your LibraryXpress system consists of more than four modules, attach a third
support bar to a module near the center of the stack, and mount a third pair of angle brackets
on the slides for that module.

Interfaces and Cabling

Refer to Figure 2-13. The connections required depend on the type of module. The Global
Control Module always has the SCSI connection to the host for the library robotics. Base
Modules have a separate SCSI connection to the host for each drive*, but the SCSI
connectors for the robotics should not be used. The portion of the library robotics that is
located in the slave modules is controlled by the Global Control Module through a cable
connected to the Global Control Interface connector on each module. Each module has a
separate AC power connection.

* In principle it is possible to daisy-chain the SCSI connections for multiple drives, to save SCSI
controllers. Overland Data strongly recommends against this practice because it may severely limit
the data throughput performance and reliability of the library.

Figure 2-13

Global Control SCSI Connectors, Terminator and Cables

(Fast/Wide SCSI Shown)

XpressChannel Motor Cable

The XpressChannel motor cable is 36 inches long and has a male DB-15 connector on each
end. Connect the cable from the connector on the motor housing to the elevator connector on
the Global Control Module.
