Table 11. Operator Panel component descriptions (continued)

Number Component Description

8 Attention LED Amber LED lit when a cartridge is incompatible with the drive, marginal,

or invalid. The LED turns OFF when the media is removed from the

drive. The LED might also be lit when there is a power supply problem.

9 Error LED Amber LED lit when there is an unrecoverable library or drive failure.

The corresponding error message displays on the LCD display.

The Operator Panel operates in two basic modes:

• User Interaction mode - Mode that is employed when a user is pushing keys on the Operator Panel.

• System Driven mode - Normal mode of operation where the Operator Panel displays status in response

to commands issued from the drive's internal interface.

When an Operator Panel key is pressed and released, the Operator Panel automatically changes to User

Interaction mode. User Interaction mode continues until 3 minutes after a user stops pushing keys, or the

requested accessor action stops, whichever is longer. Then, the Operator Panel returns to System Driven

mode.

If necessary, the Operator Panel automatically changes to System Driven mode. When this change occurs,

the library remembers what the user was doing before the display mode changed.

Any operational conflict between commands that are received over the host interface or the Web User

Interface and those commands that are entered by way of the Operator Panel are avoided with a

reservation mechanism on a rst-come, rst-served basis. Operator Panel commands are canceled by an

Operator Panel logout or timeout.

Library rmware does not allow a user to select an impossible request. Those situations include, but are

not limited to -

• Moving a cartridge from any source to a position occupied by another cartridge

• Moving a cartridge from an empty cartridge position

• Loading a cartridge from any source to a full drive

• Unloading a cartridge from an empty drive

Any error that is detected by the library or drive controller and not recoverable through predetermined

rmware algorithms is considered unrecoverable. When an error occurs, an error code is displayed on the

Operator Panel display and the error LED is ON. The error code remains on the Operator Panel until a key

is pressed, which causes the Operator Panel to return to the Home Screen. Numeric error codes are used

for unrecoverable errors. Otherwise, text status messages are displayed.

When the library powers ON or resets, it goes through several internally controlled initialization

processes, called the Power-On-Self-Test (POST).

Front panel LEDs

All LEDs are updated during power ON and reset sequences. At power ON or software reset, all LEDs turn

ON as soon as POST allows. When initialization starts, all LEDs turn OFF and the Ready/Activity LED

flashes at a rate of approximately 2 seconds per cycle. When the mechanical initialization is complete, the

Ready/Activity LED stops flashing and turns ON.

If a library failure occurs, the Ready/Activity LED turns OFF and the Error LED turns ON. The Operator

Panel also displays an appropriate error code to help identify the failure.
