4.5.1 Overview
Once the CRS-500 1:N Redundancy System and its accompanying components (switch units,
modems, etc.) have been properly cabled as outlined in this chapter, depending on the state of
operation the system may be powered up for initial configuration or for general operation.
4.5.2 Modem Power Connections
Connect the power cord for each modem as follows:
Step Task
1
Ensure that all modem power switches are in the OFF position before connecting the power
supply power cords. The design of the switch module may vary according to product, as
illustrated in Figure 4-16.
2
Each modem is supplied with a power supply cord. Connect the female end of the power cord
into the power input module.
3
Plug the male end of the power cord into the power source. It is recommended that every
other modem is connected to an alternate power source.
Note: The auto-sensing power supplies do not require any adjustments.
4 Do not turn the modem power switches ON until instructed in Sect. 4.5.4.
