SERVSWITCH™ DUO AND SERVSWITCH™ QUADRO

6. Troubleshooting

6.1 Things to Try

This section suggests possible answers for a number of problems that people
sometimes encounter when trying to operate the ServSwitch Duo/Quadro. If the
suggested actions don’t solve your problem, or if you don’t see a listing for the type
of trouble you’re having, contact Black Box Technical Support as described in

Section 6.2

.

Problem:

Poor video quality with smearing, fuzziness, or rippling.

Possible Solution:

Use shielded or screened coaxial video cables to connect your devices to the
ServSwitch Duo/Quadro.

Problem:

Your mouse does not move the cursor/pointer.

Possible Solutions:

If you move the mouse and your user station’s ACTIVITY LED doesn’t flash, then
the ServSwitch Duo/Quadro is not receiving data from the mouse. Check the
mouse’s connection to the Duo/Quadro; if it’s OK, try resetting the mouse using
the reset function (see

Section 5.7

), resetting the keyboard and mouse (see

Section 5.9

) or powering the Duo/Quadro OFF and then ON again. If you are

attempting to connect the Duo/Quadro to a CPU with a PS/2 mouse connection
that has not been powered down, you will need to use the mouse-restoration
function (see

Section 5.8

).

Make sure that the selected computer’s software is configured to accept a

Microsoft compatible PS/2 mouse of the type that you have connected.

Make sure that (a) the mouse and computer were both connected to the

ServSwitch Duo/Quadro before any part of the system was powered up, and
(b) the Duo/Quadro was powered ON before the attached computer. If you’re not
sure whether this was the case, then (if it’s possible to do so) power everything
down, make sure all cable connections are correct and secure, power up the
Duo/Quadro, then power up all attached computers.
