Reserved System Slots

Both the Base Module and the Drive Expansion Module have reserved system cells on the lower rear wall. These cells provide special functions for the library and tape drives. Do not place data cartridges in a reserved slot. The reserved cells are composed of:

• Two swap cells in column 2, rows 49 and 50.

• One diagnostic cell in column 2, row 51, and four diagnostic cells in column 3, rows 49, 50, 51, and 52.

• A module identification block in column 4, rows 49, 50, 51, and 52 (see Figure B-1).

• Four cleaning cartridges in column 5, rows 49, 50, 51, and 52, and four cleaning cartridges in column 6, rows 49, 50, 51, and 52.

Module Identification Block

Each module has an identification block with labels that identify the module configuration. This block is on the lower rear wall in the forth column from the left, rows 49, 50, 51, and 52. During an initialization or after an upgrade, the robotic assembly visits the module identification block to determine the module configuration.

The block identifies the:

• Type of module: Base Module, Drive Expansion Module, Cartridge Expansion Module, Parking Expansion Module, or Access Expansion Module.

• Back wall configuration: 1 drive array, 2 drive arrays, 3 drive arrays, 4 drive arrays, arrays, bulk load magazines, or empty.

• Front wall configuration: Arrays, cartridge access port, CAP window, empty, or bulk load magazines.

• Options: Arrays, op panel or window, empty, or service bay.
