Chapter 6 Troubleshooting
6.1 Network Communication Errors
This chapter was developed to assist you in identifying a control communications problem when using
remote control panels with Integrity™ system frames.
Integrity is designed to transmit and receive data between remote control panels (RCPs) and cards via the
Ethernet on a Local Area Network (LAN). There are several potential causes of problems identified here
with ways to isolate them and render a solution.

6.2 Recommended Network Configuration
The recommended configuration for Integrity is to use an off-the-shelf Ethernet switch to connect all frames
and RCPs. For large systems, multiple switches may be cascaded. All devices are connected using Ethernet
patch cables, such as those used to connect a PC to a switch or patch panel.
Each RCP must be assigned a unique IP and MAC address. Assignments may be changed via a menu in the
RCP. There is a specific range of addresses that are considered valid. Invalid values will cause a system
communication failure.
