Transition Networks SISPM1040-3xxx-L Web User Guide Configure NTP Server: Click this button to configure NTP server, when 'Use NTP Server' is selected at Clock Source select dropdown (see above). NTP (Network Time Protocol) is used to sync the network time based Greenwich Mean Time (GMT). If you use NTP mode and select a built-in NTP time server or manually specify a user-defined NTP server as well as Time Zone, the switch will sync the time in a short after clicking the Apply button. Though it synchronizes the time automatically, NTP does not update the time periodically without user's processing. Time Zone is an offset time of GMT. You have to select the time zone first and then perform time sync via NTP because the switch will combine this time zone offset and updated NTP time to come out the local time, otherwise, you will not able to get the correct time. The switch supports configurable time zone from -12 to +13 in 1 hour steps. Default Time zone: +8 Hrs. Parameter descriptions: NTP Time-Sync Interval: The switch is periodically transmitting NTP frames to its servers for having the network time information up-to-date. The interval between each NTP frame is determined by the NTP Time-Sync Interval value. Valid values are 5, 10, 15, 30, 60, and 120 minutes. Server 1 to 5: Provide the NTP IPv4 or IPv6 address of this switch. IPv6 address is in 128-bit records represented as eight fields of up to four hexadecimal digits with a colon separating each field (:). For example, 'fe80::215:c5ff:fe03:4dc7'. The symbol '::' is a special syntax that can be used as a shorthand way of representing multiple 16-bit groups of contiguous zeros; but it can only appear once. It can also represent a legally valid IPv4 address. For example, '::192.1.2.34'. Buttons: Apply :Click to save changes. Reset : Click to undo any changes made locally and revert to previously saved values. 33763 Rev. G https://www.transition.com Page 26 of 496
