5. Troubleshooting

If you determine that your ServSwitch™ Brand Matrix Video Switch is
malfunctioning, do not attempt to alter or repair the unit. It contains no user-
serviceable parts. Contact Black Box Technical Support at 724-746-5500.

Before you do, make a record of the history of the problem. We will be able to

provide more efficient and accurate assistance if you have a complete description,
including:

• the nature and duration of the problem;

• when the problem occurs;

• the components involved in the problem—that is, what type of cable, makes

and models of computers (input devices), makes and models of monitor
(output devices), etc.;

• any particular application that, when used, appears to create the problem 

or make it worse; and

• the results of any testing you’ve already done.

If you need to transport or ship your Switch:

• Package it carefully. We recommend that you use the original container.

• Before you ship the unit back to Black Box for repair or return, contact us 

to get a Return Authorization (RA) number.
