Quick Start Description
This Quick Start contains information you need to install and configure the router
quickly. For complete installation instructions, see the M7i Internet Router Hardware
Guide at http://www.juniper.net/techpubs/hardware/.
WARNING: This Quick Start contains a summary of safety warnings in “Safety
Warnings” on page 15. For a complete list of warnings for this router, including
translations, see the M7i Internet Router Hardware Guide at
http://www.juniper.net/techpubs/hardware/.
The M7i Internet Router is a complete routing system that provides ATM, channelized,
Ethernet, IP services, and SONET/SDH interfaces for large networks and network
applications, such as those supported by Internet service providers (ISPs).
Application-specific integrated circuits (ASICs), a definitive part of the router design,
enables the router to forward data at the high speeds demanded by current network
media.
The router accommodates up to four Physical Interface Cards (PICs). In addition to
the PICs, the Fixed Interface Card (FIC) provides two Fast Ethernet ports or one
Gigabit Ethernet port, depending on your configuration. The built-in tunnel interface
on the Compact Forwarding Engine Board (CFEB) provides tunnel services, and the
optional Adaptive Services Module (ASM) on the CFEB allows one or more services
to be configured on this interface.
The router provides very high throughput for any combination of PICs that does not
exceed 3.2 Gbps full duplex. A combination that exceeds this number is supported,
but constitutes oversubscription.
The router is shipped in a cardboard carton, secured with foam packing material.
The carton contains:
■ One accessory box (the box to which this Quick Start is taped)
■ One Juniper Networks router
■ One Quick Start (this document)
Step 1: Prepare the Site
Before installing the router, read the site preparation guidelines in the M7i Internet
Router Hardware Guide to make sure that the site meets power, environmental, and
clearance requirements for the router.
Rack-Mounting Requirements
■ You can install the router in a four-post rack or cabinet or an open-frame rack.
■ The rack must be strong enough to support the weight of the fully configured
router, up to about 36.5 lb (16.6 kg). You can mount up to 21 M7i routers in a
