Server1  The IP address of the primary SNTP server.

Server2  The IP address of a secondary SNTP server to be accessed if the primary SNTP server is unavailable.

SNTP Polling Interval  Enter the polling interval in seconds. The valid range of values is 60 to 86400. The default value is 1024 seconds (approx. 17 minutes).

Master Election  If you want the system to assign the master unit, keep the default setting, Automatically. If you want to specify the master unit yourself, select Force Master, then select unit 1 or 2 from the drop-down menu.

NOTE: If unit 1 is the master unit and unit 1 becomes unavailable, unit 2 will immediately become the master unit. If unit 1 becomes available again within 10 minutes, unit 1 will be restored as the master unit. If unit 1 becomes available after 10 minutes, unit 2 will remain the master unit. In this case, to restore unit 1 as the master unit, set Master Election to specify unit 1 as the master unit, then reboot the stack.

Stacking Ports After Reset  This indicates which Gigabit ports will be used for stacking when the system is reset. Select either Copper Ports (default) or Combo Ports.

Unit No. After Reset  This is used to change the unit numbers of the switches in the stack when the system is reset. To change a switch’s unit number, locate the unit in the Unit No. column, then select the new unit number in the Unit No. After Reset column.
