SERVSWITCH™ JR. MP

5. Troubleshooting

The first two sections of this chapter discuss some of the problems that can arise in a ServSwitch Jr. MP system and suggest possible causes and solutions. If the trouble you’re having with the Switch is something you haven’t seen before, or if the trouble seems minor, try the procedure detailed in Section 5.1 before doing anything else. If the trouble is chronic, see Section 5.2.

Sections 5.3 and 5.4 discuss what’s involved in calling Black Box and shipping your Switch.

CAUTION!

Do not open the ServSwitch Jr. MP’s cover. You could easily damage the Switch and attached devices, and if the Switch is powered you could hurt yourself as well.

5.1 Restoring Factory-Default Settings

If you’re having difficulty with a ServSwitch Jr. MP, something that often helps is resetting the Switch to its factory defaults. Follow these steps carefully:

1.Make sure that at least one powered CPU is attached to the ServSwitch Jr. MP (it doesn’t matter to which port).

2.Press and hold the “1” button on the ServSwitch Jr. MP’s front panel.

3.Press and release the RESET button, then release the “1” button. The POWER LED should flash three times, and the unit should be restored to the factory-default settings listed in Appendix A.

Now reconfigure the Switch to your desired settings. If you’re still having difficulty, refer to Section 5.2. If it doesn’t help you to solve your problem, call Black Box for technical support.
