4.4.9 Date and time

Click on Date and Time in the menu.

This menu enables initialisation of the date and time of the card in three different ways.

The date format is always of year/month/day type

 Set manually: Enables initialisation of the date and time of the card, with the values entered in the Date

and Time fields. This update is made after clicking on the Save button.

Maximum drift is +/- 2 min./month

 Accept automatic update from IPP or IPM: Enables initialisation of the date and time of the card, with

the values provide by the Intelligent Power Protector or the Intelligent Power Manager.

 Synchronize with NTP server: Enables connection with a time server, either available on the

company’s internal network or on the Web. This server communicates GMT time. The IP address or

hostname of the time server must be entered, and the time zone of your geographic area must then be

selected from the list. Connection is made with the server and the date and time are set after clicking on

the "Save" button. Time is updated every five hours, thus preventing any drift in the time. After two

attempts, if the NTP server is not accessible, the card resends periodic requests.

The card uses the NTP protocol (UDP 123 port). The "firewall" must be configured to transmit queries

outside the intranet. When ntp could not be contacted, an error message is issued at the top of the web

page.

Note 1:

The even the card is used in a UPS supporting time-stamping, the card's time is automatically synchronized with

that of the UPS.

Note 2:

After start-up, if the card is in manual mode or if no NTP server was reached, the card initializes at 01/01/1970.
