Details power-related guidelines and requirements for installation, including voltage, current, and grounding considerations to ensure reliable and safe operation.
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.
The Cisco C8400 Secure Routers have specific power and electrical wiring requirements. Adhering to these requirements ensures reliable operation of the system. Follow these precautions and recommendations when planning your site for the Cisco Cisco C8400 Secure Routers :
-
The Cisco C8400 Secure Routers are always provided with a second support dual, identical power supplies to ensure that power to the chassis continues uninterrupted if one power supply fails or input power on one line fails.
-
For power redundancy, each of the two power supplies should be connectedto a separate input power source. If you fail to do this, your system might be susceptible to total power failure due to a fault in the external wiring or a tripped circuit breaker.
-
To prevent a loss of input power, be sure the total maximum load on each circuit supplying the power supplies is within the current ratings of the wiring and breakers.
-
Provide proper grounding to avoid personal injury and damage to the equipment due to lightning striking power lines or due to power surges. The chassis ground must be attached to a central office or other interior ground system.
For additional information, please refer to the Cisco C8400 Secure Routers datasheet.
The Cisco C8400 Secure Routers can be powered by a DC or AC source. Ensure that equipment grounding is present and observe power-strip ratings. Make sure that the total ampere rating of all the products plugged into the power strip does not exceed 80 percent of the rating.
