with an NTP server. Enabling the NTP Client, which requires an Ethernet connection to an NTP server,
ensures the consistency of date and time stamps in alarms and log entries. Although the date/time is set or
displayed in the firmware in Universal Time, when displayed in the Date/Time dialog box, the value is
always in local time.
If you select the NTP Client Enabled option (the default is deselected):
• Date and Time areas become active, and you are prevented from manually setting the date and time
on the switch.
• NTP Server Discovery and NTP Server IP Address fields become active, and you can select a discovery
method.
