This manual describes hardware components, installation, basic configuration, and
basic troubleshooting procedures for the Juniper Networks MX240 Ethernet Services
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
procedures covered in this manual, see the JUNOS software configuration guides for
information about further JUNOS software configuration.
NOTE: For additional information about Juniper Networks Ethernet Services routers
and the Dense Port Concentrators (DPCs) 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.
