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 
Technical support for assistance. See the last page for global 
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 
to connected Paragon II switch. Turn off the Switch, wait for 20 
seconds, and then turn on the unit. Powering Switch from a UPS 
avoids variation in power supply to Switch. 
Repeated “MOUSE 
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. 
Mouse suddenly locks 
up when a particular 
computer is selected, 
but operates normally 
when other computers 
are selected. 
 
Loose cable from the server to the CIM. 
 
Loose Cat5 UTP cable. 
 
Paragon II components may be out of order. Verify that the server 
works with a mouse directly connected. Contact Raritan 
Technical support for assistance. See the last page for global 
contact information. 
OSUI non-functional. 
Replace the keyboard. OSUI works only with PS/2 or extended 
AT-style keyboards. 
Video is “fuzzy” or out of 
focus. 
Video Gain Adjustment is required (especially needed with LCD flat 
panel monitors). 
 
Activate OSUI (by pressing the Scroll Lock key twice rapidly). 
 
Use numeric keypad + and - keys to adjust the video image until 
it is in focus. 
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
