Setting the date/time and enabling NTP Client<br />
The Date/Time dialog allows you to manually set the date, time, and time zone on a<br />
switch, or to enable Network Time Protocol (NTP) Client to synchronize the date<br />
and time on the switch with an NTP server. Enabling the NTP client requires an<br />
Ethernet connection to an NTP server, but ensures the consistency of date and time<br />
stamps in alarms and log entries. When the date/time is set or displayed in the<br />
firmware, it is always in Universal Time. However, when displayed in the<br />
Date/Time dialog, the value is always in local time. If the NTP Client Enabled<br />
option is selected (default is un-selected), the Date and Time areas becomes inactive,<br />
thus preventing you from manually setting the date and time on the switch. The<br />
NTP Server Discovery and NTP Server IP Address fields become active, and allow<br />
you to select a discovery method (Static, DHCP, DHCPv6) and to specify an IP<br />
address.<br />
Notes:<br />
The difference between switch and workstation times must not exceed 24 hours, or<br />
the switch management application cannot connect using SSL.<br />
To manually set the date and time on a switch, do the following:<br />
<strong>1.</strong> Open the <strong>Switch</strong> menu, and select Set Date/Time.<br />
2. In the NTP area of the Date/Time dialog, clear (un-select) the NTP Client<br />
Enabled option. The fields in the Date and Time areas become active.<br />
3. Enter the day, year, hour, and minutes.<br />
4. Select a month and time zone from the drop-down lists.<br />
5. Click the OK button. The new date and time take effect immediately.<br />
To synchronize the date and time on the switch with an NTP server, do the<br />
