Operator Control Panel (OCP)
• The <Clean> LED is only lit when a 'cleaning required' has been issued by one of the drives. The
LED is turned off after a successful drive cleaning operation is performed to the requesting
drive.
• The <Media Attention> LED indicates that there is a piec
e of LTO media which is bad, marginal
or invalid. The LED clears when all such cartridges have been exported from the tape library.
• The <Error> LED illuminates when t
here is an unrecoverable (i.e. hard) drive or tape library
failure. This occurs simultaneously with the hard error message displayed on the screen - the
LED remains illuminated until the error state is resolved.
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.
Toggle Values
Toggle values are used to switch between two different states like 'on' and 'off'. After navigating to
the menu item the display shows its current state. Pressing the <ENTER> button will select the
item, whose value may then be toggled using the <UP> and <DOWN> buttons. Pressing <ENTER>
again sets the item to the displayed value.
Numerical Values
Numerical values are needed for network addresses, PIN entries, and other configuration entries.
After navigating to the menu item to be changed, the actual value will be displayed and the cursor
stays on the first digit. The value may be incremented / decremented with the <DOWN> and <UP>
buttons. After pressing the <ENTER> button to select the displayed value, the cursor moves to the
next editable digit. Each digit can be changed in the same way. After pressing the <ENTER> button
at the last digit, the complete entry will be stored. Pressing the <CANCEL> button will cancel the
whole edit process and the old value will be restored.
