The Automatic Cartridge Loader

An optional automatic cartridge loader (ACL) can be attached to the cartridge tape

drive for unattended loading and unloading of cartridge tapes. This option is available

from the factory as part of the tape drive CRU or as an upgrade installed in the field by

a trained service provider.

The ACL uses a removable cartridge magazine to store seven cartridges. Within the

ACL, an elevator mechanism (the autoloader) loads and unloads tapes from the

magazine in response to commands from the front panel or the system.

ACLs have the same operator controls as the 5190 and 5194 drives plus several

additional controls. For a description of how to operate the ACL, see Operating a

Tape Drive With an ACL on page 4-5.

Figure 1-3 shows a tape drive module in which both drive CRUs are equipped with

ACLs. In this configuration, only the front panel of the ACL is visible from the front of

the unit. The drive is mounted to the rear of the ACL inside the drive CRU.
