5.5.2 Modem Power Connections
Figure 5-15. Modem Power Interface Examples
Connect the power cord for each modem. Do these steps:
1. Ensure that all modem power switches are in the OFF position before connecting the
power supply power cords. See
Figure 5-16. The design of the switch module may vary
according to product.
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.
The auto-sensing power supplies do not require any adjustments.
4. Do not turn the modem power switches ON until instructed to.
