3.2.3 Time

The GSS-48T4SFP provides two methods to keep the switch’s time settings correct, they are

via manual input and via a Time Server on the internet. If you are manually entering your time

settings enter the “Year”, “Month”, “Day, “Hour”, “Minute” and “Seconds” into the space

provided. If you enter a number that is invalid, for instance you enter 61 in the seconds field it

will be rounded down to the nearest valid number, in this case 59.

If you are using NTP (Network Time Protocol) there are four built in Internet Time Servers that

you can use, or there is a space provided where you can enter a particular Time Server

address. When using NTP you will also need to specify what time zone you are presently

located in. The Time Zone is Greenwich-centered which uses the expression form of GMT +/-

xx hours.

Current Time: Shows the current system time.

Manual: You can set the switches time settings manually. Enter the Year,

Month, Day, Hour, Minute and Seconds into the spaces provided. The

valid figures for the parameters Year, Month, Day, Hour, Minute and

Seconds are >= 2000, 1 – 12, 1 – 31, 0 – 23, 0 – 59, respectively.

NTP: NTP is used to sync the network time with a time server on the internet

based on the Greenwich Mean Time (GMT). Once the user has selected

one of the built in time servers or entered a manual time server and

selected the correct time zone click the <apply> button to update. The

switch will now sync with the selected time server. However this

synchronisation does not occur periodically if the time does become out

of sync for some unknown reason the administrator will manually have to

click the apply button again to re-sync with the time server.

The Time Zone is an offset time of the GMT. The switch supports a

configurable time zone from -12 to +13 hours in increments of 1 hour.

Daylight Savings: Daylight Savings can be configured from -5 ~ +5 hours in increments of 1

hour. If your location has adopted daylight savings please enter the

appropriate value in the daylight savings drop down box. If your area

does have daylight savings you will need to enter a starting and ending

date of the daylight savings period. Once the date passes the starting
