Proper electrical termination is essential for each twisted-pair channel. Failure

to terminate the network can degrade performance, and in some cases, eliminate

a device’s ability to communicate with other devices. For TP/XF and TP/RS485

channels, use the terminator circuits shown in Figure 44. You can also use the

terminators provided with the NodeBuilder FX Development Tool.

Connecting Power

After the router is physically attached to the desired channels, power must be

supplied.

When power is connected to a router, the Service LED for each side changes state

as described in Figure 45. After a router is powered and configured, the Service

LEDs stay off, unless the service request button is pressed.
