a different IP address in another. For example, you could translate one public IP address to multiple private IP 
addresses on your LAN (SUA Only).

PROBLEM
CORRECTIVE ACTION
None of the LEDs turn 
on when you press 
the Prestige’s power 
button.
Make sure that you have the correct power adaptor connected to the Prestige and an 
appropriate power source. Make sure that the power source is turned on. Check all cable 
connections.
If the LEDs still do not turn on, you may have a hardware problem. In this case, you 
should contact your local vendor.
