CHAPTER 6: Troubleshooting

6. Troubleshooting

The first two sections of this chapter discuss things to try when problems arise in a
ServSwitch Ultra system. If the trouble you’re having with the Switch is something
you haven’t seen before, or if the trouble seems minor, try the procedures detailed
in 

Section 6.1

before doing anything else. The second section of this chapter

suggests possible causes of and solutions to frequently encountered problems; if
the trouble is chronic, see 

Section 6.2

. 

Sections 6.3

and 

6.4

discuss what’s involved

in calling Black Box and shipping your Switch.

CAUTION!

Do

not

open the ServSwitch Ultra’s cover. You could easily damage the

Switch and attached devices, and if the Switch is powered you could
hurt yourself as well.

6.1 Restoring Factory-Default Settings

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

carefully:

1. Make sure that the ServSwitch Ultra, any submasters attached to it, and all

CPUs directly or indirectly connected to it are turned OFF.

2. Press and hold in the 

or “–” (previous port) button on the front of the

Switch. While holding in this button, turn the Switch back ON.

3. Wait until the red (SELECT) LED of the Switch’s highest-numbered port

(port 4 on a 4-port unit, port 12 on a 12-port unit, etc.) lights up, then release
the minus button.

4. Cycle power to the Switch (push the ON/OFF button once to turn the Switch

OFF, then push it again to turn the Switch ON).

5. Select Port 1 on the ServSwitch Ultra. Power up the device on Port 1; if the

device is a CPU, wait for it to go completely through its boot-up process. Then
select Port 2, power up that device, and so on.

6. Starting with the lowest-numbered CPU and proceeding to the highest-

numbered one, power up the CPUs on the Switch’s submasters one at a time,
waiting for each to boot completely before going to the next.

Now reconfigure the box to your desired settings. If you’re still having difficulty,
refer to 

Section 6.2

. If it doesn’t help you to solve your problem, call Black Box for

technical support.
