Network Time Synchronization
*To access the Network Time Synchronization fields:
1. Navigate to System Configuration > Network > Network Time Synchronization section.
These fields are used to synchronize network time using the host name or IP address of a known server to provide a synchronized time for all appliances in the network.
Note: Network Administrators please note. DHCP Option 4 (TIME) and Option 42 (NTP) are requested from the DHCP server to obtain SNTP server addresses. One or both of these options must be enabled in the DHCP server for these addresses to be returned to the DME. If both are returned, the DME will use the NTP server address. If the DHCP server configuration is unknown, it is recommended that the address(es) be manually entered since the DHCP server-supplied address will always override a manually-entered address.
