Control Node and Network Switch Cabling 
Example

This document provides background information and detailed procedures for cabling dual 
Cassatt Active Response control nodes and network switches and for configuring those 
network switches. These procedures are an example of one way you could cable the control 
nodes and configure the switches. If your site setup differs, use this document as a guideline.

Cabling control node and switch hardware

Prerequisites

This example assumes you have completed the following tasks:

You have obtained all the required hardware.

You have determined your network address strategy and allocated the required IP 
addresses according to network requirements of 

Cassatt Active Response. 

You have configured your gateway or gateways using the static IP addresses you allocated 
from the Cassatt network.

See the 

Info Central

 site for detailed information on calculating network addresses for 

Cassatt Active Response. 

Port numbering

You must understand the switch and control node port numbering to cable the Cassatt Active 
Response environment’s hardware components together correctly. Figure 1 assumes use of a 
Cisco switch and shows switch ports, the switch module ports, and the control node ports. As 
an example, this document assumes four network switches intended for use with 24
