are not written to persistent memory until you click Apply and Restart
Field/Button
Description
Enable SNTP
Click this checkbox to enable SNTP, the device will automatically 
obtain current time from a SNTP server on the network. You must 
Apply and Restart before this change will become effective. SNTP is 
disabled by default. 
Time Zone Configuration
Time Zone
Use this panel to select the time zone where the IN-tact 1101 is 
located. This is necessary for the device to correctly calculate local 
time based on the UTC time received from NTP server(s). Daylight 
saving time is automatically calculated based on your time zone 
choice. The default time zone is Arizona (GMT - 07:00).
NTP server(s) provided by DHCP
If DHCP is enabled and the IN-tact 1101 obtained NTP server 
information from it, the first two NTP servers are displayed here and 
are available for time synchronization. 
Search NTP servers in this order
Use this panel to define the preferred search order for NTP servers. 
Servers are contacted in the order you select. The default search 
order is DHCP first, then statically-configured. 
There are two choices:
Try to connect to DHCP provided NTP servers first, then statically-
configured servers.
Try to connect to statically-configured servers first, then DHCP 
provided servers.
Static Configuration for NTP 
Servers
You have the option of configuring up to two NTP servers -- a primary 
and an alternate. The value entered can be an IP address or a 
domain name.
Time Synchronization Interval
Interval (hours)
Time is synchronized on start-up, then periodically according to the 
interval configured you specify in this panel. The interval is specified 
in hours, from 1 through 24, with 24 being the default. Time 
synchronization can be requested whenever necessary by clicking 
Synchronize Now. This button is only present if you have enabled 
SNTP and restarted the device. A message displays to inform you 
that the time synchronization process can take up to 40 seconds as a 
valid NTP server is contacted. The result (failure or success) is 
displayed on this page. An SNMP trap is generated when start-up 
time synchronization fails. After that, a failed synchronization attempt 
generates an event with no SNMP trap. If successful, the new time is 
also displayed. A successful manual synchronization resets the 
synchronization interval. In other words, the countdown until next 
synchronization is reset to zero at the time you click Synchronize 
Now
. If you are using a SNMP manager to set time synchronization, 
set your SNMP manager timeout to be at least 45 seconds to allow 
adequate time for this operation to take place. Time will be 
synchronized with the first server that successfully responds to the 
request. An event is recorded stating that time has been successfully 
synchronized, including the IP address of the NTP server that 
responded to the time request.
