TROUBLESHOOTING
Possible Cause
The PowerCenter
is not turned on.
The PowerCenter is sharing AC power with
equipment that is not properly grounded.
Remedy
• Make sure the PowerCenter's AC power plug
is plugged into a properly grounded 120
volts (nominal) wall outlet.
• A wall switch may need to be turned on. Try
turning on the light switches located near
the wall unit powering the PowerCenter.
• 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.
