Paging a switch

You can use the beacon feature to page a switch. The beacon feature causes all Logged-In LEDs to flash, making it easier to recognize. Select Switch > Toggle Beacon (check mark shown) to page a switch. Select Switch > Toggle Beacon again (check mark removed) to cancel the beacon.

Setting the date/time and enabling NTP client

The Date/Time and Network Time Protocol (NTP) dialog enables you to manually set the date, time, and time zone on a switch, or to enable the NTP Client. The NTP client synchronizes the date, time, and time zone on the switch with an NTP server. Enabling the NTP client ensures the consistency of date and time stamps in alarms and log entries. An Ethernet connection to an NTP server is required. When date/time is set or displayed in the firmware, it is displayed based on the time zone configured. However, when displayed in the Date/Time dialog, the value is always in local time. The difference between switch and workstation times must not exceed 24 hours, or the switch management application can not connect. To set the date and time on a switch:

1.Select a switch in the fabric tree to open the faceplate display.

2.Select Switch > Set Date/Time.

3.Choose one of the following:

•Enter the year, month, day, time, and time zone in the Switch Date/Time dialog. The new date and time take effect immediately.

•Select a time zone option from the Select Time Zone pull-down list.

•Select the NTP Client Enabled option to enable the switch to synchronize its time with an NTP server. Enter the IP address of the NTP server. Ethernet connection to NTP server is required.

4.Click OK to save the settings.
