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 Table A-3; 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.
