Chapter 8 Basic Setting The following table describes the labels in this screen. Table 11 Basic Setting > General Setup LABEL System Name Location Contact Person's Name Use Time Server when Bootup DESCRIPTION Choose a descriptive name for identification purposes. This name consists of up to 64 printable characters; spaces are allowed. Enter the geographic location of your Switch. You can use up to 32 printable ASCII characters; spaces are allowed. Enter the name of the person in charge of this Switch. You can use up to 32 printable ASCII characters; spaces are allowed. Enter the time service protocol that your timeserver uses. Not all time servers support all protocols, so you may have to use trial and error to find a protocol that works. The main differences between them are the time format. When you select the Daytime (RFC 867) format, the Switch displays the day, month, year and time with no time zone adjustment. When you use this format it is recommended that you use a Daytime timeserver within your geographical time zone. Time (RFC-868) format displays a 4-byte integer giving the total number of seconds since 1970/1/1 at 0:0:0. NTP (RFC-1305) is similar to Time (RFC-868). Time Server IP Address Current Time New Time (hh:mm:ss) Current Date New Date (yyyymm-dd) Time Zone Daylight Saving Time None is the default value. Enter the time manually. Each time you turn on the Switch, the time and date will be reset to 1970-1-1 0:0. Enter the IPv4 or IPv6 address of your timeserver. The Switch searches for the timeserver for up to 60 seconds. If you select a timeserver that is unreachable, then this screen will appear locked for 60 seconds. Please wait. This field displays the time you open this menu (or refresh the menu). Enter the new time in hour, minute and second format. The new time then appears in the Current Time field after you click Apply. This field displays the date you open this menu. Enter the new date in year, month and day format. The new date then appears in the Current Date field after you click Apply. Select the time difference between UTC (Universal Time Coordinated, formerly known as GMT, Greenwich Mean Time) and your time zone from the drop-down list box. Daylight saving is a period from late spring to early fall when many countries set their clocks ahead of normal local time by one hour to give more daytime light in the evening. Start Date Select this option if you use Daylight Saving Time. Configure the day and time when Daylight Saving Time starts if you selected Daylight Saving Time. The time is displayed in the 24 hour format. Here are a couple of examples: Daylight Saving Time starts in most parts of the United States on the second Sunday of March. Each time zone in the United States starts using Daylight Saving Time at 2 A.M. local time. So in the United States you would select Second, Sunday, March and 2:00. Daylight Saving Time starts in the European Union on the last Sunday of March. All of the time zones in the European Union start using Daylight Saving Time at the same moment (1 A.M. GMT or UTC). So in the European Union you would select Last, Sunday, March and the last field depends on your time zone. In Germany for instance, you would select 2:00 because Germany's time zone is one hour ahead of GMT or UTC (GMT+1). VES1724-56 User's Guide 73
