Chapter 2 Preparing for Installation
Site Requirement Guidelines
Temperature and Humidity Guidelines
The operating and nonoperating environmental site requirements are listed in
Table A-4 on page A-4. 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 “Router Bonding and Grounding Receptacles—Top Rear” section on
page 2-23 for grounding requirements.
