Connecting the Power
Cisco 7120 series and Cisco 7140 series routers feature four-output switching AC power supplies that
provide power factor correction and regulated outputs. Cisco 7120 series routers have one AC-input
power supply and Cisco 7140 series routers have two AC-input power supplies.
Cisco 7140 series routers will operate with power connected to either of the two power supplies. The
second AC-input power supply simply enables power load-sharing and redundancy. There is no primary
or secondary power supply for Cisco 7140 series routers.
For information on the power supply specifications, see Appendix B, “System Specifications.”
Warning Do not touch the power supply when the power cord is connected. For systems with a power switch,
line voltages are present within the power supply even when the power switch is off and the power
cord is connected. For systems without a power switch, line voltages are present within the power
supply when the power cord is connected.
The AC power supply has double pole/neutral fusing.
Check the following conditions before you start the router:
• The port adapter is securely inserted in its slot.
• All network interface cables are connected.
• A Flash Disk or Flash memory card is installed in its PC Card slot.
• The console terminal is connected and powered on.
