Temperature and Humidity Guidelines
The operating and nonoperating environmental site requirements are listed in Environmental Specifications,
on page 142. The router normally operates within the ranges listed in Environmental Specifications, on page
142; 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.
