Cisco ASR 9000 Series Aggregation Services Router Hardware Installation Guide

Chapter 1 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 the table; 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

Each Cisco ASR 9000 Series Router is powered by only one type of input: AC or DC. A hybrid (AC+DC)
power configuration is not supported.

Caution

Proper grounding is necessary to avoid damage from lightning and power surges. See

NEBS

Supplemental Unit Bonding and Grounding Guidelines, page 1-52

for grounding requirements.
