Symbol Technologies AP-5131 - Manual (Page 110)

AP-5131 Access Point Product Reference Guide 4-34
This option is disabled when the Enable NTP on AP-5131 checkbox has been selected, and
therefore should be viewed as a second means to define the AP-5131 system time.
4. If using the Manual Date/Time Setting screen to define the AP-5131’s system time, refer to
the
Time Zone field to select the time used to use as complimentary information to the
information entered within the Manual Date/Time Setting screen.
5. If using an NTP server to supply system time to the AP-5131, configure the NTP Server
Configuration field to define the server network address information required to acquire
the AP-5131 network time.
6. Click Apply to save any changes to the Date and time Settings screen. Navigating away
from the screen without clicking the Apply button results in all changes to the screen being
lost.
7. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the
settings displayed on Date and Time Settings screen to the last saved configuration.
8. Click Logout to securely exit the AP-5131 Symbol Access Point applet. A prompt displays
confirming the logout before the applet is closed.
Enable NTP on
AP-5131
Select the Enable NTP on AP-5131 checkbox to allow a
connection between the AP-5131 and one or more specified NTP
servers. A preferred, first alternate and second alternate NTP
server cannot be defined unless this checkbox is selected.
Disable this option (uncheck the checkbox) if Kerberos is not in use
and time synchronization is not necessary.
Preferred Time Server Specify the numerical (non DNS name) IP address and port of the
primary NTP server. The default port is 123.
First Alternate Time
Server Optionally, specify the numerical (non DNS name) IP address and
port of an alternative NTP server to use for time synchronization if
the primary NTP server goes down.
Second Alternate
Time Server Optionally, specify the numerical (non DNS name) and port of yet
another NTP server for the greatest assurance of uninterrupted
time synchronization.
Synchronization
Interval Define an interval in minutes the AP-5131 uses to synchronize its
system time with the NTP server. A synchronization interval value
from 15 minutes to 65535 minutes can be specified. For
implementations using Kerberos, a synchronization interval of 15
minutes (default interval) or sooner is recommended.
