The CIM's mouse cable to the computer is loose. Secure the
connection and turn on the computer again.
If the problem only occurs to new computers which are just added to
the system, the firmware in the KVM (TMCAT17 internal mouse
emulator) may need to be upgraded to a later version to be
compatible with newer computers. Contact your dealer or Raritan for
help.

Try to identify if the problem is originating from the computer by
reconnecting the computer to a different channel with a different
cable. Then turn on the computer. If the problem is not with the cable
or with a specific channel, connect the mouse directly to the
computer. If the problem persists, then the computer's mouse port is
out of order. Otherwise, contact your dealer or Raritan for help.
If the problem occurs after the TMCAT17 switch has been installed
for a period of time, and occurs to computers that have previously
worked with the TMCAT17 switch, then some components are out of
order. Contact your dealer or Raritan Technical Support for help.
