Configuration; Setting Slave Configuration (Base Module Only) - Overland Data DLT LibraryXpress Series Service Manual

3. Determine whether the module is to be connected in daisy-chain fashion with other
devices.
•
If not used in a daisy-chain, install the terminator in the second SCSI
connector.
•
If used in a daisy-chain, and the drive is the last device of the chain, install the
terminator in the second SCSI connector. Otherwise, do not use the terminator.
Connect the next cable in the chain to the second SCSI connector.
4. Make sure that the cable you use meets the specifications listed earlier in this
chapter.
5. Measure the cable length to connect the module to the computer system.
6. Be sure that the length of the entire bus falls below the maximum permissible length
given in the section on SCSI cable specifications

Configuration

Individual Base Modules in all newly assembled systems must be configured as described in
the next section. In addition, the LibraryXpress System is designed with several configuration
options, each offering multiple settings to support a variety of applications and platforms. The
setting of each option is stored in non-volatile memory in the module. For most applications,
you will not need to change the factory default settings.
To change settings, you need to use the Control Panel on the Global Control Module. For an
overview of how the Control Panel works, and a description of the functions of the buttons,
indicators and display, refer to the sections titled 'Entering the Menu Mode,' 'Exiting the
Menu Mode,' and 'Navigating Through the Menu Structure' in Chapter 3 - Operation.
The settings can be changed using the procedure described below under "A Configuration
Example - Setting the SCSI ID." Before changing any configuration settings, consult your
host system documentation to determine which settings may need to be changed.

Setting Slave Configuration (Base Module Only)

Important Note: All Base Modules are shipped configured as standalone systems. Before
powering up the Global Control Module in a LibraryXpress system for the first time, you
must reconfigure each of the Base Modules in the system as a slave. To do so, perform the
following procedure on each Base Module.
1. Turn on the power switch on the Base Module. After a series of self-test screens, the
screen shown in Figure 2-16 appears.
