The Link Lock check-box is now unavailable.
5. If required, repeat the procedure for Site B.
Setting the Date and Time
The ODU maintains a date and time. The date and time should be synchronized with any Net-
work 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 syn-
chronization with an NTP Server.
Note
To revert the Link Lock status to unlocked, power down each ODU
in turn. Use the above procedure to uncheck the Link Lock status
box for the live ODU.
A simple ODU reset at either end will restore the link to its previous
locked or unlocked state.
Note
The NTP uses UDP port 123. If a firewall 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.
