This product complies with the performance standards set by the U.S. Food and
Drug Administration for a Class II Laser Product. This product belongs to a class of
laser products that requires precautions be taken to avoid prolonged viewing of the
laser beam. Under normal working conditions, you must not come in direct contact
with the laser beam. This classification was accomplished by providing the
necessary protective housings and scanning safeguards to ensure that laser
radiation is inaccessible during operation or is within Class II limits. These products
have been reviewed by external safety agencies and have obtained approvals to
the latest standards as they apply to this product type.
Operator Safety
The operator should remember the importance of safe operation when performing
any of the tasks in this book. The operator should know the location and how to use
the switches and controls on the IBM 3494 Tape Library.
Safety Characteristics
The front doors on the library should not be opened during normal operation
because of the moving components within the library. The doors have key locks to
prevent the doors from being opened inadvertently. The 3494 includes integral
safety control circuits that detect whether the doors are open or closed.
When a door is detected to be open, the power is removed from the cartridge
accessor and the picker slowly descends. All host systems attached to the tape
subsystems or through the RS-232 interfaces associated with the library are notified
of the condition. This gives the operator a warning of a safety exposure and a
warning of potential unauthorized access to the cartridges stored in the library.
