Objectives

This manual describes hardware installation and basic troubleshooting procedures

for the Juniper Networks M160 Internet router. It explains how to prepare your

site for router installation, unpack and install the hardware, power on the router,

perform initial software configuration, and perform routine maintenance. After

completing the installation and basic configuration p rocedures covered in this

manual, refer to the JUNOS Internet software c onfiguration guides for information

about further JUNOS software configuration.

NOTE: For additional information about Juniper Networks Internet routers and the

Physical Interface Cards (PICs) they support—either corrections to or information

that might have been omitted from this guide—see the hardware release notes at

http://www.juniper.net/.

Audience

This guide is designed for network administrators who are installing and

maintaining a Juniper Networks router or preparing a site for router installation. To

use this guide, you need a broad understanding of networks in general, the Internet

in particular, networking principles, and network configuration. Any detailed

discussion of these concepts is beyond the scope of this guide.
