No Response to Commands in ML Net

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.

No Connectivity Via Ethernet

If All Else Fails...

•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, http://NO500H.yourhome.network.com

•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.
