• The most likely cause of the problem is either a voltage ʺspikeʺ
(increase) or a ʺbrown outʺ (decrease) in the power supply, which
would cause the microprocessors in the MCCAT to malfunction. A
short‐term solution to the problem is to try to recover operation by
turning the MCCAT power switch off and on. Then, if necessary,
restart all computers. The long‐term method of avoiding this
problem is to power MCCAT from a UPS.

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

• Try to identify if the problem is originating from the computer by
reconnecting the computer to a different channel with a different
cable. Then power 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 computerʹs mouse port is
out of order. Otherwise, contact your dealer or Raritan for service.

• If the problem occurs after MCCAT has been installed for a period
of time, and occurs to computers that have previously worked with
MCCAT, then some components are out of order. Contact your
dealer or Raritan for service.
