Symptom Probable cause
Repeated “Keyboard
ERROR” at computer
power-up.
Loose cable from the server to the CIM.
Loose Cat5e UTP cable.
Paragon II components may be out of order. Verify that the server
recognizes a keyboard that is directly connected. Contact Raritan

contact information.
Keyboard suddenly
locks-up when a
particular computer is
selected, but operates
normally when other
computers are selected.
Loose keyboard cable connection.
Voltage spike (increase) or brown out (decrease) in power supply

seconds, and then turn on the unit. Powering Switch from a UPS
avoids variation in power supply to Switch.

INSTALLATION
FAILURE” at computer
power-up.
Loose mouse cable from the server to the CIM
Loose Cat5 UTP cable. If an error occurs only with new servers
being added to the system, contact Raritan Technical Support for
assistance—mouse emulation firmware may need to be
upgraded for compatibility with newer servers. See the last page
for global contact information.

The USB Combo
keyboard and USB
mouse do not function
properly.
You may not follow the procedure described in this user guide to
connect the USB Combo keyboard and mouse. Power cycle the user
station to resolve the issue. See How to Connect a USB Combo
Keyboard (on page 48) for more information.
Access to an available
channel is unsuccessful
and the OSUI shows
"Switch busy. Please try
again."
If two or more users highlight the same channel and press Enter to
access the channel almost "at the same second," the access conflict
occurs. The system will accept one user's access and reject the
others. Those who are rejected see the message "Switch busy.
Please try again." on the OSUI.
When this occurs, try to access the same channel again seconds
