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. 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.
Problem:
Your mouse does not move the cursor/pointer.
Possible Solutions:
If you move the mouse and the activity indicator (the dot on the 7-segment
display) does not flash, then the ServSwitch Duo is not receiving data from the
mouse. Check the mouse connection to the Switch; if it’s OK, try resetting the
mouse using the reset function (see Section 3.3) or powering the Switch OFF and
then ON again. If you are attempting to connect the Switch to a CPU with a PS/2
mouse connection that has not been powered down, you will need to use the
mouse-restoration function F5 or F6 (see Section 5.11).
Make sure that your software is configured to accept a Microsoft compatible
mouse of the type that you have connected (PS/2 or RS-232).
Make sure that (a) the mouse and computer were both connected to the
ServSwitch Duo before any part of the system was powered up, and (b) the Switch
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 Switch, then power up all
attached computers.
