The backlit, 4-line by 20-character control panel display provides a highly
intelligible presentation of drive and loader status, menu choices and error
messages. The scrolling feature greatly expands the amount of information
available to you. In the MiniLibrary Expansion Unit, status information is
available for the entire system. The slave modules display other information as
needed for localizing malfunctions.
The magazine security lock is a key-operated switch on the front panel of each
module. It can be used to prevent inadvertent removal of the cartridge
magazine.
The AC power switch is located on the front panel of the module. The
autoranging power supply adjusts automatically to either of two operating
voltage ranges. The ranges are 100-120 VAC and 200-240 VAC. The power
supply is capable of operating at 50 or 60 Hz without any adjustment or
modification. AC power is supplied to the power supply by a single
IEC-compatible socket that can be connected to any properly grounded outlet.
The 10-cartridge and 16-cartridge magazines are removable from the front
panel, but can be protected from tampering by any of three means:
1. A key-operated magazine security lock must be unlocked before the
magazine can be removed,
2. An electronic combination lock operated by using buttons on the
Expansion Unit control panel.
3. Issuance by the host of a SCSI PREVENT MEDIUM REMOVAL
command.
The rugged carbon-fiber-reinforced polymer magazine fits into an extruded
track, which assures precise positioning with respect to the library robotics. A
10-cartridge tape magazine is shown in Figure 2-14.
