Port event selection:
5.4.6 Fault Relay Alarm
The Fault Relay Alarm function provides the Power Failure and Port Link Down/Broken detection. With both power input 1
and power input 2 installed and the check boxes of power 1/power 2 ticked, the FAULT LED indicator will then be possible
to light up when any one of the power failures occurs. As for the Port Link Down/Broken detection, the FAULT LED
indicator will light up when the port failure occurs; certainly the check box beside the port must be ticked first. Please refer
to the segment of 'Wiring the Fault Alarm Contact' for the failure detection.
Device warm start: When the device executes warm start, the system will
issue the event log/email alert to the system log/SMTP server respectively.
Authentication Failure: When the SNMP authentication fails, the system will
issue the event log/email alert to the system log/SMTP server respectively.
X-ring topology change: When the X-ring topology has changed, the
system will issue the event log/email alert to the system log/SMTP server
respectively.
Also, before the drop-down menu items are available, the Syslog Client Mode
selection item on the Syslog Configuration tab and the E-mail Alert selection
item on the SMTP Configuration tab must be enabled first. Those drop-down
menu items have 3 selections—Link UP, Link Down, and Link UP & Link
Down. Disable means no event will be sent to the system log/SMTP server.
Link UP: The system will only issue a log message when the link-up event of
the port occurs.
Link Down: The system will only issue a log message when the link-down
event of port occurs.
Link UP & Link Down: The system will issue a log message at the time
when port connection is link-up and link-down.
