Preparing to Connect to a Network
Power Supply Considerations
Check the power at your site to ensure that you are receiving “clean” power (free of spikes
and noise). Install a power conditioner if necessary.
Warning The device is designed to work with TN power systems. (To see translated
versions of this warning, refer to the Regulatory Compliance and Safety Information
document that accompanied the router.)
The router power supply includes the following features:
• Autoselects either 110V or 220V operation.
• All units include a 6-foot (1.8-meter) electrical power cord. (A label near the power cord
indicates the correct voltage, frequency, current draw, and power dissipation for the
unit.)
Warning This product relies on the building’s installation for short-circuit (overcurrent)
protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S.
(240 VAC, 10A international) is used on the phase conductors (all current-carrying
conductors). (To see translated versions of this warning, refer to the Regulatory Compliance
and Safety Information document that accompanied the router.)
If you encounter trouble with your power supply, refer to the section “Troubleshooting the
Power and Cooling Systems” in the appendix “Troubleshooting the Router.”
Preparing to Connect to a Network
When setting up your router, consider distance limitations and potential electromagnetic
interference (EMI) as defined by the EIA.
