Troubleshooting Hardware
If your controller is not coming online, you need to follow some basic troubleshooting steps.
Controller Connectivity
The first step is to establish what is between the server and controller
Server
Controller
Depending on whether the controller and server are on the same sub network or not will affect how you go
about troubleshooting
Simple Networks
If the server and controller are on the same sub network, troubleshooting the network path is somewhat easier
Server
Controller
Switch
192.168.10.100 192.168.10.201
Devices on the same sub network only have switches or hubs connecting them together
This means the server and controller should be able to communicate directly if they are both physically
connected to the network
Complex Networks
If your network has routers between the controller and server, then troubleshooting can be more difficult
Server

Controller
10.10.1.100 203.86.25.12 203.96.14.26 10.12.1.201
Troubleshooting networks such as these are beyond the scope of this qualification
