SERVSWITCH™ WIZARD MULTIMEDIA KVM EXTENDER
6. Troubleshooting
If you have difficulty with your ServSwitch™ Wizard Multimedia KVM Extender,
see if the problem is listed in
Section 6.1
and, if so, try the suggested remedies. You
can also, at any time, reset the Extender itself as described in
Section 6.2
. If
nothing helps, get the Extender’s firmware-revision level as described in
Section 6.3
if possible, then call Black Box Technical Support as directed in
Section 6.4
. If you need to ship your Extender, see
Section 6.5
.
6.1 Things To Try
Problem:
Poor video quality with smearing, fuzziness, or rippling.
Possible Solution:
Make sure that the video compensation has been set for your system, as described
in
Section 4.2.2.A
. Make sure your Category 5 cable is pinned and paired properly;
see
Appendix A
. Also, if you are using cables other than those that came with the
Extender to make your video connections, make sure these are shielded or
screened coaxial video cables.
Problem:
Video is lost during periods of very high audio output.
Possible Solution:
Turn down the CPU’s maximum audio-output level.
Problem:
Your mouse does not move the cursor/pointer.
Possible Solutions:
1. Are you trying to use it with a Compaq laptop computer connected to the
Extender with a “Y” cable? If so, you need to set position 4 of Unit A’s DIP
switch ON and power the Extender down and back up again to get the
Extender to detect the mouse properly. See
Section 4.2.1
.
2. If you’re using the mouse at the primary station, do this test: Watch Unit B’s
red Control LEDs while you move the mouse. If you move the mouse and
these LEDs don’t flash, then the Extender is not receiving data from the
mouse—proceed with the next few steps.
3. Check the mouse’s connection to the Unit and (if you’re using the primary
mouse to control the primary CPU) the CAT5 cabling between the Units; if
the cable connections are OK, try removing and restoring power to the
Extender.
