LOCAL UNIT OPERATION 41
Local Console Commands
After pressing the initial ‘hot’ key on the Local keyboard, you can issue a number of
commands by pressing additional keys. These commands allow you to start a private mode
session on the Local console or to reset the keyboard and mouse.
These commands only apply to Local units and Rack hubs having firmware
versions ‘S50’ and above.
Command Key Sequence
Private Mode <Scroll Lock>
Local units that feature dual access (ACU2009A, ACU2028A) allow the Local user to lock
out the Remote console by triggering a ‘Private Mode’ function. This prevents the Remote
console from being used even if the two second inactivity timeout period expires.
During a Private Mode session, the extender system:
• Flashes the Scroll Lock LED on the Local keyboard.
• Illuminates all three LEDs on the Remote keyboard.
• Displays a blank image on the Remote console’s monitor.
• Locks the Remote console’s keyboard and mouse.
Reset Local Keyboard and Mouse <Num-Pad Up Arrow>
Resets the Local console’s keyboard and mouse. Use if the mouse or keyboard locks up or
the mouse does not initialize correctly.
Send NULL Mouse Byte <Num-Pad Left Arrow>
Use this command if you experience erratic movement of the mouse pointer. This can occur
when the mouse signal synchronization is lost. The command sends a null mouse byte to the
system and then automatically exits Command Mode. You may need to enter the command a
number of times to re-synchronize the mouse signal. Alternatively, stop moving the mouse
for a few seconds and the operating system’s mouse drivers may automatically re-
synchronize the signal.
