Date
and
Time
Setting
the
Date
and
Time
The
ODU
maintains
a
date
and
time.
The
date
and
time
should
be
synchronized
with
any
Network
Time
Protocol
(NTP)
version
3
compatible
server.
During
power
‐
up
the
ODU
attempts
to
configure
the
initial
date
and
time
using
an
NTP
Server.
If
the
server
IP
address
is
not
configured
or
is
not
reachable,
a
default
time
is
set.
When
configuring
the
NTP
Server
IP
address,
you
should
also
configure
the
offset
from
the
Universal
Coordinated
Time
(UTC).
If
there
is
no
server
available,
you
can
either
set
the
date
and
time,
or
you
can
set
it
to
use
the
date
and
time
from
the
managing
computer.
Note
that
manual
setting
is
not
recommended
since
it
will
be
overridden
by
a
reset,
power
up,
or
synchronization
with
an
NTP
Server.
To
set
the
date
and
time:
1.
Determine
the
IP
address
of
the
NTP
server
to
be
used.
2. Test
it
for
connectivity
using
the
command
(Windows
XP
and
7),
for
example:
Enhanced
Security*:
Immediately
implement
the
enhanced
security
option.
When
and
if
the
unit
is
reset,
there
is
a
2
‐
minute
grace
period
where
the
enhanced
security
option
is
temporarily
removed.
After
this
time,
the
enhanced
security
option
is
re
‐
established
automatically.
Enhanced
Security:
Immediately
implement
the
enhanced
security
option.
The
NTP
uses
UDP
port
123.
If
a
fire
wall
is
configured
between
the
ODU
and
the
NTP
Server
this
port
must
be
opened.
It
can
take
up
to
8
minutes
for
the
NTP
to
synchronize
the
ODU
date
and
time.
