Serial Event Settings 
The Serial Event Settings page is located under Auto Warning Settings in the System Management 
folder. This is where you specify how the NPort will notify you of DCD and DSR events for each serial port. 
Mail refers to sending an e-mail to a specified address. Trap refers to sending an SNMP trap. 
A change in the DCD (Data Carrier Detect) signal indicates that the modem connection status has changed. 
If the DCD signal changes to low, it indicates that the connection line is down. A change in the DSR (Data 
Set Ready) signal indicates that the data communication equipment is powered off. If the DSR signal 
changes to low, it indicates that the data communication equipment is powered down. 
ATTENTION 
SNMP indicates a change in DCD or DSR signals but does not differentiate between the two. A change in 
either signal from “–” to “+” is indicated by “link up” and a change in either signal from “+” to “–” is 
indicated by “link down.”
