SL4000 Modules

There are five types of modules in an SL4000 library, with a total of 15 modules allowed in a single library.

Note:

Refer to your SL4000 library publications for the latest updates to configuration and feature availability, as needed.
  • Base module, one, required

    This module consists of a single frame, which centralizes the infrastructure for all other modules in the library. One Base Module, and only one, is required for every library installation.

    On the front of this module is:

    • A single, 26 cartridge-dual magazine-cartridge access port (CAP).

    • A service door for library access.

    • A front panel with three LEDs: Library Active, Service Required, and Wait.

    • An optional feature for a touch screen operator panel or window.

  • Drive Expansion Module (DEM), maximum of three

    This module allows further expansion of tape drives and provides additional data cartridge capacity. A maximum of three Drive Expansion Modules can be added to the required Base Module, on any side of the base module.

  • Cartridge Expansion Module (CEM), maximum of twelve

    This module provides additional cartridge cell capacity and growth. It does not include tape drives. A maximum of twelve Cartridge Expansion Modules can be added, though the maximum number is dependent on the number of other module types present.

  • Parking Expansion Module (PEM), leftmost and the rightmost side modules

    These are the left-most and the right-most side modules. They are the same as the cartridge expansion module, with six columns of arrays (three on the front wall and three on the rear wall) that are inaccessible to allow the library to park a defective robot. In the left PEM, it is the three leftmost columns (front and back). In the right PEM, it is the three rightmost columns.

  • Access Expansion Module (AEM)

    See Using the AEM for more information.

Note:

An SL4000 with dual robots has either AEMs or PEMs.
