TROUBLESHOOTING
Possible Cause
The component is plugged into a switched outlet
and the PowerCenter has not been turned On.
The PowerCenter is plugged into a Switched outlet, but power on the
component is not On. In some instances, a component plugged
into a switched outlet won't receive power when the PowerCenter is
turned On unless the component power is also switched On.
The PowerCenter is sharing AC power with equipment
that is not properly grounded.
Remedy
• Turn the PowerCenter On.
• Or, plug the component into an Unswitched outlet.
• Turn the component power On.
• Connect your PowerCenter to a dedicated outlet.
• Try unplugging different components from the
PowerCenter one at a time to see if the noise stops.
If a component is discovered to be improperly grounded,
attach a copper wire from the component's chassis
to the PowerCenter's grounding post.
