Troubleshooting:
Ensure that all cables are well seated. Check that keyboard/mouse
cables are not swapped. Label and bundle the cables for each computer
to avoid confusion when connected to the StreamLine.
Symptom Possible causes Recommended solutions
Nothing works Bad connection at the
C-36 connectors
Push the assembled drawer and
the KVM module box firmly
together leaving on
ly 8mm (5/16
inch) space in between. Be sure
they are secured by two screws.
VGA monitor

keyboard and
touch pad does

Another keyboard or
mouse is connected to
the rear side of the KVM
module box (marked with
Local) when the C-
36
connector is connected
to the KVM drawer.
Connection inside the
KVM drawer becomes
loose due to vibration.
If the C-
36 connector on the KVM
module box connects to a KVM
drawer, its Local
console should
not connect to any keyboard or
mouse.
Verify if t
he KVM drawer is bad by
disconnecting it from the KVM
module box (the C-
36 connector
is not connected). Connect a
keyboard, mouse and monitor to
the Local
port on the KVM
module box and another
computer to any of the PC
ports
and use the KVM module box as
a stand-alone KVM switch.
