Hot Standby Diagnostics

Diagnosing Hot Standby

If the synchronization between the Ethernet communication modules does not work properly before the Hot Standby switchover occurs, use the information on the Hot Standby Diagnostic page.

NOTE: Before you can open the Diagnostic window, connect the DTM for the target communication module to the physical module itself. To do this, select the module node in the DTM Browser, then select Edit → Connect.

Open the page:

1	In the DTM Browser, select the communication module and click the right mouse button. A pop-up menu opens.
2	In the menu, select Device menu → Diagnostic. The Diagnostic window opens.
3	In the left pane of the Diagnostic window, select the communication module node.
4	Click on the Hot Standby Diagnostic tab to open that page.
