Nº500H Series Power Amplifier

1. Verify that the master device and the Nº500H series amplifier are

properly connected together with a router.

2. Verify that the Nº500H series amplifier’s network setup is correct.

Access to the internal Web page via a computer is required to 
verify the network settings of the Nº500H series.

•   Verify that the network cables are properly connected between

the router, switch, or hub and the amplifier. If connecting to 
a computer, verify that the computer network cable is in the 
correct port.

•   Verify the age of the router, switch, or hub. There may be

a communication issue with the Nº500H series and older 
network devices. Power cycle the Nº500H series and use a 
newer router, switch, or hub between the network and the 
amplifier.

•   If connected directly to the computer, make sure a crossover

cable is used.

•  Verify that the router and computer have valid IP addresses.

•   Verify that the proxy server in the computer’s network setup is

disabled. An active proxy server can interfere with the software
upgrade procedure.

•   If the web browser cannot find the host name of the amplifier,

verify the following:

• Ensure that the local DNS server is properly configured.

We recommend configuring the local DNS Server to “DNS 
Forwarding” mode. To configure the DNS Server, refer to
the setup manual of the server.

• If using a subdomain, enter the complete address into the

browser. For example,

• Enter the IP Address of the amplifier into the browser. For

example, “http://192.168.50.5”

1.    Power-cycle the Nº500H series, waiting at least 10 seconds 

between powering the amplifier off and on.

2.   Restore the default settings on the internal web page.
