Temperature and Humidity Guidelines
The operating and nonoperating environmental site requirements are listed in
on page 120
. The router normally operates within the ranges listed in
Environmental Specifications, on page
120
; 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.
