CHAPTER 6: Troubleshooting

6. Troubleshooting

If you have difficulty with your ServSwitch™ Duo Extender, see if the problem is
listed in

Section 6.1

and, if so, try the suggested remedies. If you’ve forgotten your

password, see

Section 6.2

. If you need to reset the Extender to its factory defaults,

see

Section 6.3

. If nothing seems to help, get the Extender’s firmware-revision level

as described in

Section 6.4

if possible, then call Black Box Technical Support as

directed in

Section 6.5

. If you need to ship your Extender, see

Section 6.6

.

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, make sure any cables you’re using to make your monitor/

CPU video connections are shielded or screened coaxial video cables.

Problem:

Your mouse does not move the cursor/pointer.

Possible Solutions:

1. Watch the Extender’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.

2. Check the mouse’s connection to the Extender and the CAT5 cabling

between the Extender and the Duo; if the cable connections are OK, try
removing and restoring power to the Extender.

3. If you are attempting to connect the mouse to a PS/2 mouse port on a Duo

CPU that has not been powered down, you will need to use the Duo’s mouse-
restoration function (see the “Hot-Plugging Devices Into the ServSwitch
Duo...” section in the Duo manual). If you’re attempting to connect the
mouse to a non-powered-down local CPU on a KV6EXT-R2 Extender, use the
Extender’s mouse-restoration function (see

Section 5.9

of this manual).

4. Make sure that you have an appropriate mouse driver loaded and that your

computer’s software is configured to accept a supported mouse of the type
that you have connected. See the relevant paragraphs in

Section 3.1

.
