Installation
Operating Environment
The ND series is not water or moisture proof and is designed for indoor use only. Treat it as you
would any other delicate electronic device and do not expose it to water, excessive heat, or physical
abuse. See the Specifications section for details on the environmental/operational conditions.
Pre-Installation Checklist
Before installing an ND, 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 ND 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 (MAC) 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.
