Powering-on the Library
▼ To power-on the library
1. Close and lock the front access door if the doors are open.
Note – If you DO NOT want to power-on the robots, CAPs, and the elevators, leave the
doors open.
2. Move the system power-off/on switch to ON (1) position.
Note – If the library has a 2N power configuration, you must switch on the system
power on both the PDUs.
See FIGURE 4-11 on page 69 and FIGURE 4-12 on page 70 for detailed illustrations.
Maintenance Mode of Operation
Maintenance mode is active when a service representative enters the access door to
perform maintenance or to replace a component.
An example of this would be the replacement of a defective HandBot when a
redundant or operational HandBot is available. Each HandBot has two motors, if one
fails, the other motor is powerful enough to move the defective HandBot into the
forward service area. If both the motors fail for a HandBot, then the redundant
HandBot moves the defective HandBot into the forward service area thus continuing
HandBot operations. The service representative then requests that the library be made
available for maintenance entry on the side where the HandBot is positioned. The
maintenance key (available only to a service representative) is inserted, a service safety
door moves to the side selected (partitioning the service area from operational library
activity) and the HandBot is replaced.
Note – The service safety door is not parallel to the front of the library; its right side is
angled toward the rear of the library (see FIGURE 1-2 on page 4 ).
Service Safety Door Operation
During the replacement, the library continues to function. Because there are cartridge
arrays in the forward portion of the Customer Interface Module, these slots are
reserved for diagnostic and cleaning cartridges only. A mount request for a cartridge in
the slot closer to the side (left or right) where the service safety door is engaged may be
