buttons. When you press either button
for more than one-half second, the control panel behaves as if you were pressing and
releasing the button about four times per second. This effect stops when you release the
button.
Front Panel & Media Locks
To avoid accidental interruption of PowerLoader™ operation by entering the Menu Mode or
removing cartridges while the host is accessing the PowerLoader™, the front panel and the
media may be electronically locked. When the front panel is locked, you can only enter the
Menu Mode after entering a 4-digit code. That is, when the Default Screen is displayed,
pressing the
Enter
button does not invoke the Menu Mode until you enter the code. The front
panel cannot be unlocked without using the Security submenu to unlock it.
The media may also be locked by software running on the host, using the SCSI Prevent/Allow
Medium Removal command. The PowerLoader™ provides no control panel override for this
command. Usually, exiting the host software restores media access. In the event of host failure,
you can restore media access by cycling PowerLoader™ power.
Procedures for locking and unlocking front panels and media are described later in this chapter.
