Connecting Network Cables

NetClock provides a base 10/100 Ethernet port for full NTP functionality, as well as a comprehensive web-based user interface ("Web UI") for configuration, monitoring and diagnostic support. Additional network ports are available with the Gigabit Ethernet option module.

First, you need to decide how you want to configure basic network connectivity e.g., the IP address:

  1. Configure NetClock via the unit's front panel (NetClock 9483 only): See Setting Up an IP Address via the Front Panel.

    If your unit does not have a front panel, see Setting Up a Temporary IP Address Remotely.

  2. Configure NetClock by means of a PCPersonal Computer connected to an existing network.
    • When connecting to a hub, router, or network computer, use a straight-through wired, shielded CAT 5, Cat 5E or CAT 6 cable with RJ-45 connectors. Connect one end to the Ethernet port on the NetClock rear panel, and the opposite end of the cable to a network hub or switch.
  3. Configure NetClock by connecting a stand-alone computer directly via a dedicated network cable (standard-wired, or crossover cable):
    • When connecting directly to a stand-alone PC, use a network cable. Connect the cable to the NIC card of the computer.
      Since no DHCP server is available in this configuration both NetClock, and the PC must be configured with static IP addresses that are on the same subnet ( and with a subnet value of on both devices, for example). For more information on configuring static IP addresses, see Assigning a Static IP Address.

Once the unit is up and running, verify that the green link light on the Ethernet port is illuminated. The amber “Activity” link light may periodically illuminate when network traffic is present.
