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.
Quick Start Description
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

floor-to-ceiling rack. If you do so, the rack must be capable of supporting a combined weight of over 766 lb (347 kg).
■ The rack rails must be spaced widely enough to accommodate the router chassis's
external dimensions: 3.5 in. (8.9 cm) high, 18.2 in. (45.7 cm) deep, and 17.5 in. (44.5 cm) wide. The mounting hardware extends the width to fit into standard 19-in. racks.
■ For service personnel to remove and install hardware components, there must
be adequate space at the front and back of the router. At least 24 in. (61.0 cm) both in front of and behind the rack or cabinet is required. NEBS GR-63 recommends at least 30 in. in front of the rack or cabinet.
■ The rack or cabinet must have an adequate supply of cooling air:
that produces heat.
■ 2.8 in. (7.1 cm) is required between the side of the router and any large
surface that does not produce heat, such as a wall.
■ In a closed cabinet, there must be a minimum of 6 in. (15.2 cm) of
unobstructed airflow behind the router, or airflow baffles must be installed
to prevent recirculation of hot air and overheating.
■ If the router is the only unit in the rack, mount it at the bottom of the rack.
■ When mounting the router in a partially filled rack, load the rack from the bottom
to the top with the heaviest component at the bottom of the rack.

Step 1: Prepare the Site

Tools Required

■ Phillips (+) screwdriver, numbers 1 and 2
■ Electrostatic discharge wrist strap
■ Antistatic mat
■ Blank panels to cover any slots not occupied by a component

Step 2: Prepare for Front or Center Mounting

The cable management system organizes and supports the PIC cables to prevent damage. The mounting brackets are shipped installed in the front-mounting position, but must be removed to install the cable management system.
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and
connect the strap to one of the ESD points on the chassis.
2. Use a number 2 Phillips screwdriver to remove the screws from the front and
rear of the mounting brackets on the chassis. Remove the mounting brackets.
3. Locate the cable management racks and appropriate screws in the accessory
box.
4. Slide the cable management racks into the slots at the front of the chassis.
5. Use a number 2 Phillips screwdriver to tighten the screws that secure the cable
management system to the chassis.
6. Reinstall the mounting brackets.
■ Front-mount: Reinstall the mounting bracket in the position shown in
Figure 2 on page 6 and replace the screws.
■ Center-mount: Install the mounting brackets in the center-mounting position
and replace the screws.

6 ■ Step 2: Prepare for Front or Center Mounting

Step 3: Install the Router

1. Have one person grasp each side of the router, lift the router, and position it in
the rack. See Figure 4 on page 8.
2. Align the bottom hole in each mounting bracket with a hole in each rack rail,
making sure the chassis is level.
3. Install a mounting screw (provided in the accessory box shipped with the router)
into each hole. Use a Phillips screwdriver to tighten the screws.
4. Install a screw into the second hole in each mounting bracket.
5. Verify that all the mounting screws on one side of the rack are aligned with the
mounting screws on the opposite side and that the router is level.
