Chapter 2      Preparing for Installation
Site Requirement Guidelines
Temperature and Humidity Guidelines
The operating and nonoperating environmental site requirements are listed in 
. The router normally operates within the ranges listed in 
Table A-4, 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
Proper grounding is necessary to avoid damage from lightning and power surges. 
See the 
 for grounding requirements.
