Time

Use the Time screen to view and adjust date and time settings. The Switch supports Simple Network Time Protocol (SNTP). SNTP assures accurate network device clock time synchronization up to the millisecond. Time synchronization is performed by a network SNTP server. This software operates only as an SNTP client and cannot provide time services to other systems.

In the System Time section you can use the following options:

Options Description

Current time

Displays the current time.

Enable SNTP

Select whether to Enable or Disable the SNTP server. The system time is set via an SNTP sever.

SNTP/NTP Server Address

Enter the SNTP or NTP sever IP address or hostname.

Server Port

Displays the time sever port.

Time Zone

Select the difference between Greenwich Mean Time (GMT) and local time.
Daylight Saving Time (DST)

Enable to reflect the observance of daylight saving time.

Notes on countries observing and non observing Daylight Saving Time.

    When selecting countries where DST is not observed, the DST option is disabled by default and user cannot enable.
    When group of countries is selected, with some observing DST and others not, the user has the flexibility to enable or disable DST according to their preference.

To configure date/time through SNTP

  1. In the Enable SNTP settings, select the Enable option to configure the date or time through SNTP.
  2. In the SNTP/NTP Server Address field, enter the IP address or the host name of the SNTP/NTP server.
  3. Enter the port number on the SNTP server to which SNTP requests are sent. The valid range is from 1–65535. The default is 123.
  4. In the Time Zone Offset list, select by country or by the Coordinated Universal Time (UTC/GMT) time zone in which the Switch is located.
  5. If required, select Daylight Saving Time to reflect the observance of daylight saving time.
  6. Click Apply to update the system settings.

To configure date/time manually

  1. In the Enable SNTP settings, select the Disable option to configure the date or time manually.
  2. In the Manual Time settings, select the date, time, and choose the appropriate time zone.
  3. Click Apply to update the system settings.

In the Schedule section you can configure a time schedule for connected Power over Ethernet (PoE) enabled devices that are active only during business hours. This helps save energy, reduce electricity consumption, and lower associated costs.

To add a schedule

Utilize the scheduling feature to manage the timing of PoE ports on the Switch. Create a schedule object, and then apply it across the PoE ports.

  1. Click + icon to add the schedule object.
  2. Enter a name for the new schedule.
  3. Select the type of schedule from the list:
    • Once- This options allows the selection of one schedule profile defined by setting the Start and End date and time.

    • Recurring-This option allows the configuration of a recurring entry with up to seven entries defined. Select the day and time for each schedule. Each profile allows scheduling up to seven entries.

    • Mixed- Allows to add both once and recurring schedule entries. Select the day and time for each schedule in both Once and Recurring settings.

Next go to the Switching > Port Settings > PoE tab to select these schedule profiles that are available for PoE usage on the switch port.
