The router normally operates within the ranges listed in the table; however, if a temperature measurement is
approaching a minimum or maximum parameter, it indicates a potential problem. Maintain normal operation
by anticipating and correcting environmental anomalies before they approach critical values by properly
planning and preparing your site before you install the router.
Power Connection Guidelines
You can configure the router with either an AC input or DC input power subsystem, so the site power source
requirements differ depending on the power subsystem in your router. Ensure all power connection wiring
conforms to the rules and regulations in the National Electrical Code (NEC) as well as local codes.
Each Cisco ASR 9000 Series Router is powered by only one type of input: AC or DC. A hybrid (AC+DC)
power configuration is not supported.
