Date and Time Chapter 6RADWIN 5000 HPMP User Manual Release 3.2.00 6-14Figure 6-6: Alternative Community Dialog boxDate and TimeSetting the Date and TimeThe 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 theUniversal Coordinated Time (UTC). If there is no server available, you can either set the dateand time, or you can set it to use the date and time from the managing computer. Note thatmanual setting is not recommended since it will be overridden by a reset, power up, or syn-chronization 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), for example:w32tm /stripchart /computer:216.218.192.202NoteThe NTP uses UDP port 123. If a fire wall is configured between the ODUand the NTP Server this port must be opened.It can take up to 8 minutes for the NTP to synchronize the ODU date andtime.
