Checking a Connection Using Direct Link
In case of an optical fiber link (as shown in
connection is checked as follows:
•
Both devices at the link ends have to be switched on.
•
Check in the event log or in the spontaneous annunciations:
–
If the message
with the device index of the other device in case of an optical fiber conductor, a link has been estab-
lished and one device has recognized the other.
–
If the message
with the device index of the other device in case of a copper connection, a link has been established
and one device has recognized the other.
–
The device indicates
been detected.
•
In case of an incorrect communication link, the indication
faulty (no. 3232) is displayed. In this case, check the connection again:
