Temperature and Humidity Guidelines
The operating and nonoperating environmental site requirements are listed in Table A- 2. The router
normally operates within the ranges listed in Environmental Specifications, pageA-2; 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.
Caution Each Cisco ASR 9001 Router is powered by only one type of input: AC or DC. A hybrid (AC+DC)
power configuration is not supported.
