Automatic
Synchroniza
tion
NTP Server 1.
Enable clock automatic synchronization with an NTP server. You can
specify two NTP servers by entering their IP addresses. NTP Server 1 is
the primary and NTP Server 2 is the secondary.
IMPORTANT:
• With automatic synchronization configured, the device periodically
synchronizes its time with the NTP server. If the synchronization
fails, the system uses the manually configured time. After the
synchronization recovers, the system uses the synchronized time.
• The IP address of an NTP server is a host address, and cannot be a
broadcast or a multicast address, or the IP address of the local clock.
• If the system time of the NTP server is ahead of the system time of
the device, and the difference between them exceeds the Web idle
time specified on the device, all online Web users are logged out
because of timeout.
