Modules
The SL150 Modular Tape Library is comprised of two types of modules: the base
module (designated Module 1) and the expansion module (designated as Modules 2
through 10).
The base module is the smallest fully functional library. The base module contains:
the front control panel, two 15-slot tape magazines (left and right), a mailslot, one
robotic hand, a power supply (with an option to add a second power supply), one
tape drive (with an option to add a second drive), and the robotics. Up to three tape
slots in the base module can be designated as reserved slots to store diagnostic or
cleaning tapes. The bridge drive
must reside in the base module.
At the rear of the base module there is an Ethernet port for remote management and
nine USB Type A ports for connection to expansion modules (see
FIGURE 1-2 ).

An expansion module can be added to the bottom of the library to provide additional
tape cartridge capacity and additional performance by adding tape drives (see
FIGURE 1-1 on page 11 ). An expansion module requires 2U of rack space. An
expansion module ships with two 15-slot tape magazines (left and right), a module
controller, and an expansion cable. The module controller is connected to the base
module by an expansion cable that incorporates USB Type A connectors. The cable
provides a communication path between the base and expansion modules and a
power source for the module controller.
The module has slots for two tape drives and two power supplies. There is
insufficient power from the expansion cable to support a tape drive. Therefore, a
power supply is required when the expansion module has a tape drive.
