TABLE 2-2
Operator Panel Switches
Switch Description
Menu Pressing the Menu switch accesses the menu system, steps through a series of
submenus, or answers No to a displayed question. Pressing the Menu switch the first
time causes the Online/Offline selection to display.
See x for information/guidance with the menu system.
Select Pressing the Select switch accesses a displayed submenu, steps through possible
options of a submenu, or answers Yes to a displayed question. When the drive is
Online and in a view only submenu, pressing Select is the same as pressing Menu.
IPL Pressing the IPL switch causes the drive to execute an initial program load (IPL)
sequence. During IPL, the drive firmware loads from non-volatile memory in an
EEPROM, to RAM. The same process occurs at power-on.
Unload Pressing the Unload switch causes the tape cartridge to rewind, unthread, and
unload; ending with the tape cartridge ejected and retrievable.
If this switch is pressed during a write operation, the drive attempts to write the
remaining data before it unloads. A display of UnWr xxxx (meaning Unwritten Data,
where xxxx is a fault symptom code) means that the attempt failed and some data
remains unwritten to tape.
Note –
Pressing
Unload
a second time causes the
unwritten data to be lost. Before you press
Unload
again,
see
UnWr xxxx
