62 Configuring the ViconNet System XX112-36-00 Rev 909 Kollector Hybrid Network Digital Video Recorder
Configuring the Nucleus
The Nucleus takes an active role in the ViconNet system, acting as a central station that connects all
devices running the ViconNet application. This is why the ViconNet system is designed in a way that will
allow it full operation even if the Nucleus is down. The information on the Nucleus is always sent to all
devices (after any update), so in a case where the Nucleus goes down, they can use that data to operate
until the Nucleus is restored. In such cases, only “new” actions that require the Nucleus, will not work (like
adding a new site). The more devices connected to the system, the more resources the Nucleus requires.
The device holding the backup Nucleus files, which runs at all times, can also be configured as a safety
mechanism for cases when the system does not operate due to a problem, such as a power failure in the
Nucleus. When there is a failure on the Nucleus device, all systems that were connected to the Nucleus will
display as “not connected.” The user can then change the name of the backup workstation to the computer
name of the original Nucleus Workstation and then change the IP of the “Backup” to be the same as that of
the Nucleus PC. Then the user must restore the settings from the Nucleus backup folder to the “Backup
Nucleus.” This makes this device transparent to the other Workstations and they will all connect to it as if
they are connected to the original Nucleus PC.
In a small network (fewer than five sites), the Nucleus and backup Nucleus (if it exists) can be on any of the
transmitters or Workstations and a backup Nucleus should only be configured if deemed necessary. If the
Nucleus is configured on a site and it is heavily loaded with recordings and transmissions, the Nucleus
should be moved to a dedicated Workstation. In a large network (more than five sites), it is strongly
recommended that the Nucleus and backup Nucleus be run on dedicated Workstations.
Creating a New Network
This procedure provides a five-step example of how to create a new ViconNet network using a field-proven
method of setup and commissioning. In this example, we will create a network made up of Kollectors with
RAIDs and Workstations.
Step 1: Setting the Sites' IP Addresses, page 63
Step 2: Configuring the Network Setup for a Master Nucleus System, page 64
Step 3: Configuring a Site to Connect to Nucleus, page 65
Step 4: Connecting the Master Nucleus to the Backup Nucleus, page 65
Step 5: Testing the Network, page 66
NOTES:
To prevent problems, it is recommended that you methodically plan your network ahead of time.
Do not use this procedure to modify an already existing network.
Before beginning, ensure that all CAT5 cables to the transmitters and Workstations are connected to a hub
or switch and that they are properly wired on each end, per 568B (or 568A). It is important to not mix
connection methods or connect or disconnect cables when the application is running.
