3. Installation
Before installation, power off all devices that will be connected to this system.
• Make sure that all devices you will connect are properly grounded.
• Place cables away from fluorescent lights, air conditioners, and machines
that are likely to generate electrical noise.
• Make sure that the DisplayPort video drivers are installed correctly on all
computers.
3.1 PC BIOS Notice
The following BIOS setup changes are necessary for PC users and not necessary
for Mac users:
• In standard CMOS, set “Halt on Error” to “All but keyboard.”
• In PNP and PCI setup, set “PNP OS installed” to “YES” and set “USB IRQ” to

Appendix: Troubleshooting
Appendix. Troubleshooting
Make sure that all cables are well-seated and labeled associated with each
computer to avoid confusion when connected to the unit.
The unit has built-in power protection that works automatically when needed.
When it works, USB communication halts and the only way to restart the unit
properly is to remove all power sources (USB cables and power adapter), wait a
few seconds, then apply power sources, and start again.
A.1 Problems/Causes/Solutions
Symptom: Keyboard or mouse does not work.
Causes:
• In Auto Scan, keyboard and mouse are not operable.
• Too many keyboards or mouse drivers are installed.
Solutions:
• Press any front-panel button to select a computer, then use the keyboard and
mouse.
• Remove all unnecessary keyboards and mouse drivers.
Symptom: Newly-installed USB device does not work.
Causes:
• Improper device driver.
• Device consumes too much power.
• Device consumes too much power instantaneously.
• Improper device initialization.
• When the unit works under self-power (that is, no power supply is added), it
supports a maximum of 100 mA as per USB specifications.
Solutions:
• Re-install the device driver.
• The device should be self-powered. Add a power adapter to the device.
Page 20
724-746-5500 | blackbox.com
Page 21
Appendix: Troubleshooting
• If the device does not have a power jack, add a power adapter with 9–12 VDC
and less that 1-A current rating to the unit.
• Make sure the USB cable is well-seated for good communications.
• Remove all power sources to the unit by unplugging all USB A–B cables and the
power adapter; then start all over again.
• Select the computer by push button, restart the computer, and try again.
Symptom: Computer hangs up while switching computer.
Causes: Device initialization or enumeration takes too much time.
Solutions:
• Wait at least five seconds before computer switching to ensure proper USB
communication.
• Turn off the device driver (not the keyboard or the mouse) before computer
switching.
Symptom: Auto Scan does not switch PC automatically, and the unit beeps.
Causes: All PCs are off or only one PC is turned on. Scan mode works for
powered-on computers only.
Solution: Turn on computers.
Symptom: No video signal when users plug and unplug the DisplayPort
connector or switch from port to port.
Cause: Some DisplayPort video cards do not respond to the signal switch
simultaneously.
Solutions:
• Make sure that you have plugged a monitor to the console’s DisplayPort port
before plugging/unplugging the PC’s video connector(s).
• Wait for a few seconds.
724-746-5500 | blackbox.com
Page 21
Page 22
Appendix: Troubleshooting
Symptom: When switching between computer ports, the DisplayPort monitor
displays “No Signal.”
Cause: Computer has gone into sleep mode or was not booted up while the con-
sole was selected on that specific computer.
Solution: If the DisplayPort video drivers are not installed, or are installed
incorrectly, the computer cannot be brought out of sleep mode by
using the keyboard and mouse. Also, when booting up a computer,
the respective port needs to be selected until the OS has fully booted
up. DisplayPort technology requires knowing exactly what is connected
when it initializes its video signal.
