TS2900 Tape Autoloader Setup, Operator, and Service Guide
The Operator Panel operates in two basic modes.
•
User Interaction mode – Mode 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 transitions to User Interaction mode. User Interaction mode will
continue 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 will automatically transition to System Driven mode.
When this occurs, the library remembers what the user was doing before the display
mode changed.
Any operational conflict between commands received over the host interface or the
Web User Interface and those entered via the Operator Panel are avoided with a
reservation mechanism on a first-come, first-served basis. Operator Panel commands
are canceled by an Operator Panel logout or timeout.
Library firmware will not allow a user to select an impossible request. Those
situations will 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 detected by the library or drive controller and not recoverable through
predetermined firmware algorithms is considered fatal. 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 fatal 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 two
Clean Drive LED Amber LED lit when the drive needs cleaning. The LED turns OFF after
the drive is cleaned successfully.
Attention LED Amber LED lit when a cartridge is bad, marginal, or invalid. The LED
turns OFF when the media is removed from the drive. The LED may
also be lit when there is a power supply problem.
Error LED Amber LED lit when there is an unrecoverable library or drive failure.
The corresponding error message appears on the LCD display.
