Connecting SX-200 IP Nodes
You can connect up to two SX-200 IP Nodes to the SX-200 EL. The system requires one Control
Triple CIM card (three onboard CIM circuits) in the main control cabinet.
The following connections are required to configure the SX-200 IP Node:
• Connections between peripheral bays and the main control cabinet are made with standard
CIM connections, page 41.
• An Ethernet crossover cable connects the Control Triple CIM Card in the main control
cabinet to the CIM port on the IP Node. All voice and signalling communications are carried
over this connection.
• Another Ethernet crossover cable connects the IP Node to the Ethernet switch on the LAN.
• The IP phones are connected to the LAN through the Ethernet switch.
The configuration rules that apply to connecting standard peripheral bays to the control cabinet
through CIMs also apply to connecting IP Nodes. For more information about configuration,
