5.4 Mode Select Key
The Mode Select key (Figure 5-2), on the front of the loader, locks the loader transfer
assembly into the enclosure and locks the receiver closed. The key has four modes:

Servicing procedures
5.4.1 OCP Disabled Mode
When the magazine is inserted into the receiver and the receiver is closed, the loader
transfer assembly scans the magazine. The first cartridge in the magazine
automatically loads into the drive.
When you copy data to the tape, operations stop if one of the following happens:
•
Storage capacity of the last tape cartridge is exceeded
•
No tape cartridge is in the next sequential slot in the magazine
To lock the DLT4700 mini-library into the enclosure and lock the receiver, set the
Mode Select key to OCP Disabled.
The following results of setting the Mode Select key to OCP Disabled are:
•
The OCP pushbuttons are disabled.
•
SCSI media changer commands are disabled.
•
If the receiver were open and a magazine were then inserted, the lowest-numbered
cartridge is automatically loaded into the drive. Subsequently, issuing the SCSI
‘unload’ command would unload the cartridge and load the next higher-
numbered cartridge.
