Q24 Tape Library Installation and Operations Manual
© Copyright QUALSTAR 2014 22
3.1.3 Power ‐ Up Display
When the library powers up or resets, it goes through several internally controlled processes that
initialize and prepare the unit for normal operation. These processes are called Power‐On‐Self‐Test
(POST). While the POST is in process, the OCP will display appropriate information to keep the user
informed. When the library finishes POST, it will display the current library status for a defined time
or until a front panel key is pressed.
After this initial status screen, the home screen will be displayed until any key is pressed. The home
screen shows the overall health of the library, indicating the status of the media changer and the
connected drives.
3.1.4 Note about the LED’s
All LED’s are updated during power up and reset sequences. Upon power up or software reset, the
library will illuminate all LED’s at some point during the POST process. This will help the user to verify
whether all LED’s are functional. When initialization starts, all LED’s will be extinguished and the
ready/activity LED will flash at approximately two‐second intervals. When the mechanical
initialization is complete, the ready/activity LED will stop flashing and remain constantly illuminated.
If a library failure occurs, the ready/activity LED will be turned off and the error LED will be
illuminated. The OCP will also display a specific error code to help identify the failure.
The following are additional operational details regarding the LED’s.

The <Ready/Activity> LED will be lit any time the unit is powered on and functional (i.e.
successfully completed the power‐on self‐test). The LED will blink whenever there is any tape
library or drive activity. The LED will also blink when the unit is offline.

The <Clean> LED will only be lit when a ‘cleaning required’ has been issued by one of the drives.
The LED will be turned off after a successful drive cleaning operation is performed to the
requesting drive.
 The <Media Attention> LED will indicate that there is a piece of LTO media which is bad,
marginal or invalid. The LED will be cleared when all such cartridges have been exported from
the tape library.
 The <Error> LED will be lit when there is an unrecoverable (i.e. hard) drive or tape library
failure. This will occur simultaneously with the hard error message displayed on the screen; the
LED will remain illuminated until the error state is resolved.
3.1.5 Input Modes
There are several modes for entering values in the different menu items. These values may be
selectable predefined values, toggle values (e.g. on/off) or numerical values like network addresses.
Selectable predefined values
After navigating to the menu item, the various predefined values can be selected with the <DOWN>
and <UP> buttons. As soon as the display shows the desired value, it may be confirmed by pressing the
<ENTER> button.
