The Time Configuration Page contains information concerning the configuration of the EX1401’s
source of time, and provides the ability to modify it.
•
Time Configuration
:
o
Time Zone
: Allows the user to select the time zone for displaying the current local time.
o
Time Source
: Selects the method to use for setting the EX1401’s time.
▪
PTP2
: Precision Time Protocol Version 2 (IEEE 1588-2008) will be used to synchronize
the EX1401’s time with a master clock on the network, or to act as master clock, based
on the IEEE 1588 Best Master Clock algorithm.
▪
NTP
: Network Time Protocol will be used to synchronize the EX1401’s time to a remote
server, which is specified in the
NTP Server
field below.
▪
Manual
: The time will be set manually by the user via the
Set Time
option below.
o
NTP Server
: The IP Address or hostname of the server from which to derive time when the
NTP
option is selected. If this is left blank, one of the following values will be used by instead:
▪
If the EX1401 is configured for DHCP, and if the DHCP server supplies the address of an
NTP server, that will be used.
▪
Otherwise, the default value of pool.ntp.org will be used.
o
Set Time
: Checking the
Set Time
box causes the
Date
and
Time
fields to appear. They will be
automatically populated with the current time of the user’s PC. When using the
Manual
option,
this sets the EX1401’s current date and time. When using the
PTP2
option, this causes a message
to be sent to the current master clock, requesting that it set its time.
