Display
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 the operator. In the Global
Control Module, status information is available for the entire system. The slave modules
display other information as needed for localizing malfunctions.
Magazine Security Lock
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.
Power Supply
The AC Power switch is located on the front panel of the module. The autoranging power
supply will adjust 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 which can be connected to any properly grounded outlet.
Tape Cartridge Magazines
The ten-cartridge and sixteen-cartridge magazines are removable from the front panel, but
may be protected from tampering by any of three means: 1) a key-operated Magazine Security
Lock which must be unlocked before the magazine can be removed, 2) an electronic
combination lock operated by using buttons on the Global Control Module control panel, and
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 ten-cartridge tape magazine is shown in
Figure 1-4. Insertion and removal of the magazine is described in Chapter 3 - Operation.
