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 Expansion Unit 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 2–49.
