Site Requirement Guidelines

Temperature and Humidity Guidelines

The operating and nonoperating environmental site requirements are listed in
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)

requirements.

AC-Powered Routers

AC power modules operate in the input range of 180 VAC to 264 VAC, 47 to 63 Hz (nominal input level
of 200 to 240 VAC). Refer to
1 and version 2 power modules.
Power redundancy requirements vary based on the system configuration (number and type of line cards,
etc.). AC-powered systems are 2N protected. A minimum of two power supplies are required for
redundant operation. Refer to the Cisco ASR 9000 Power Calculator at the following URL to determine
actual redundancy requirements for any given configuration:
