that you connect the USB cables first.
No mouse or keyboard operation from peripherals attached to User Access Node
• Ensure that the mouse and keyboard cables are connected to the correct PS/2 or USB ports on
the User Access Node. Match the connector color codes (green for mouse and purple for
keyboard).
• Ensure that both of the USB connectors from the Computer Access Node are securely con-
nected to the correct connectors on the remote computer.
• If the remote computer can provide only one USB port for the Computer Access Node:
• Use an external power supply for the Computer Access Node
• Ensure that the Computer Access Node USB cable labeled “2” is attached to the available
USB port of the remote computer
• Ensure that the correct keyboard layout is configured on the remote computer for the keyboard
you are using.
• Retest the mouse and keyboard by connecting them directly to the remote computer and reboo-
ting. If one does not function correctly, replace it.

• Ensure that the audio cable is securely plugged into the line-out port of the remote computer
(should be color-coded green).
• Ensure that the speaker cable is securely plugged into the line-out port of the
User Access Node.
• Verify that the audio sample rate has not been set to “off” for either the Computer Access Node
or the User Access Node. See Audio Performance Settings on page 38.
• Ensure that the same audio sample rate has been set for both the Computer Access Node and
the User Access Node. See Audio Performance Settings on page 38.
• Verify that the speakers are powered.
• Retest the speakers by connecting them directly to the remote computer. If they do not function
correctly, replace them.
