Pre-Installation Checklist
Before installing a ND-CLK, one should be prepared with the following basic
configuration information that the device will require. It may be necessary to obtain
some or all of this information from a network administrator in your organization.
Static Networking Configuration
__ IP address and netmask designation for device
__ Primary and secondary DNS (domain name) servers
__ Gateway/router
__ Primary and secondary NTP time sources
Dynamic Networking Configuration (DHCP/BOOTP)
__ Confirm that a DHCP/BOOTP service is accessible on the local network
__ Determine if DHCP server will provide NTP server configuration
__ Determine if DHCP server will provide time zone configuration
NTP Addressing Mode
__ Determine if the clock (client) will query the NTP server (unicast mode), listen for NTP
broadcast messages (broadcast mode) , or listen to NTP as part of a multicast group (multicast
mode)
All network clocks can be provided with a verbose name. The name is arbitrary and may
be useful for organizing and managing devices once installed at a facility. By default,
device names are the product name abbreviation followed by the device’s Ethernet
address. Customers may wish to designate names relating to their own organizational
requirements. It is recommended that a robust naming scheme be developed before
devices are installed to different locations within an organization.
