Configuring the Card
To set the date and time:
1 Click Time from the menu bar to open the Setting time page.
2 To manually set the date and time, select Set manually and enter values in the Date and Time
fields, and click Save. Maximum drift is ±2 min/month.
3 To synchronize the time with the NTP server, select Synchronize with NTP server. Selecting this
option enables a connection with a time server, available either on the company's internal network
or on the Web. This server communicates GMT time.
S
Enter the IP address or host name of the time server.
S
Select the time zone for your geographic area from the list.
S
Click Save to connect with the server and set the date and time.
The time is updated every five hours to prevent any time drift. After two attempts, if the NTP
server is not accessible, the card shifts to manual mode. The card uses the NTP protocol (UDP 123
port). The firewall must be set to transmit queries outside the intranet. No error message is
generated if the time server contact fails.
NOTE: After startup, if the card is in manual mode, or if no NTP server was reached, the card initializes at 00:00
01/01/1970.
NOTE: If the card is installed in a UPS that supports time-stamping, the card's time is automatically
synchronized with that of the UPS.
