MULTI-HEAD SERVSWITCH™

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 Multi-Head ServSwitch. 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 Multi-

Head ServSwitch.

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 Multi-Head ServSwitch is not receiving data from

the mouse. Check the mouse’s connection to the Switch; if it’s OK, try resetting the

mouse using the reset function (see Section 5.7), warm-resetting the Switch (see

Section 5.10) 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 5.8).

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 Multi-

Head ServSwitch 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.
