Cartridge Position Indicator
A seven-segment LED display in the center of the ACL control panel displays the
cartridge position number currently selected by the ACL autoloader mechanism. The
ACL lets you select which cartridge to load (from one of seven slots in the cartridge
magazine). To change the selected cartridge position number, you press the
POSITION button on the control panel.
In addition to the numbers 1 through 7, seven other codes can appear on the cartridge
position indicator. Table 4-5 lists these codes and describes events that display them.
Bringing the ACL and Tape Drive Online or Offline
A tape drive must have a tape cartridge loaded before it can be brought online. The
tape cartridge must be unloaded before the tape drive can be brought offline.
The following table summarizes the operator activities:
If power is removed from the ACL while the DOOR LOCK LED is unlit, the door can be
opened and the magazine can be removed. If power is removed while the DOOR
LOCK LED is lit, the door remains locked to protect the cartridges within the ACL and
drive. See Unlocking the ACL Door When Power Is Removed on page 4-20.
