Problem
Solution
After
a
period
of
trouble
‐
free
operation,
the
keyboard
attached
to
MCCAT
locks
(unable
to
input
keystrokes)
when
a
particular
computer
is
selected,
but
works
normally
when
other
computers
are
selected
•
The
most
likely
cause
of
the
problem
is
either
a
voltage
ʺ
spike
ʺ
(increase)
or
a
ʺ
brown
out
ʺ
(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.

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.

Try
to

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

directly
to
the
computer.

the
problem
persists,
then
the
computer
ʹ
s
mouse
port
is
out
of
order.
