Table 7.2: NS1 + NS2: Network Status (one per port)

Check: Link Status

The status of the Ethernet link cannot be directly identified by means of the LEDs.

Use par. EN-10, Link Status to verify presents of the link.

Use par. EN-11, Link Duration to verify that the link is steady present.

The parameter will show the duration of the present link, and preset to 00:00:00:00 if the link is broken.

Check: Cabling

In rare cases of cabling mis-configuration, the option might show the presents of a link, but no communication is running. Exchange the cable in doubt.

Check: IP Address

Verify that the option has a valid IP address (please refer to section: IP Settings) in par. EN-01, IP Address. If the option has identified a duplicate IP Address NS

LEDs will light steady red. If the option is set up for BOOTP or DHCP, verify that a BOOTP or DHCP server is connected in par. EN-04, DHCP Server. If no server is

connected, the parameter will show: 000.000.000.000.
