M7i Internet Router Quick Start

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

Quick Start Description ■3

Quick Start Description

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:

■6 in. (15.2 cm) is required between the side of the router and any equipment

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.

4■Step 1: Prepare the Site

Step 1: Prepare the Site ■5

Step 1: Prepare the Site

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.

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.

■Connect a Management Console or Auxiliary Device on page 9

■Connect to a Network for Out-of-Band Management on page 9

■Connect FIC and PIC Cables on page 9

8■Step 4: Connect External Devices and PIC Cables

M7i Internet Router Quick Start

Figure 5: Connect External Devices and PIC Cables to Router

Connect a Management Console or Auxiliary Device

1. Turn off the power to the console or auxiliary device.

2. Plug the female end of the RS-232 serial connector into the CONSOLE or

AUX/MODEM port.

3. Use a 2.5 mm flat-blade screwdriver to tighten the screws on the connector.

4. Connect the other end of the cable to the console or auxiliary device.

Connect to a Network for Out-of-Band Management

1. Turn off the power to the networking device.

2. Plug one end of the Ethernet cable (with RJ-45/RJ-45 connectors) into the MGMT

port on the Routing Engine.

3. Plug the other end into the networking device.

Connect FIC and PIC Cables

WARNING: Do not look directly into a fiber-optic transceiver or into the ends of

fiber-optic cables connected to a transceiver. Fiber-optic transceivers contain laser

light sources that can damage your eyes.

Step 4: Connect External Devices and PIC Cables ■9

Step 4: Connect External Devices and PIC Cables

CAUTION: To prevent damage to fiber-optic transceivers and fiber-optic cables,

observe the following precautions:

■Do not leave a fiber-optic transceiver uncovered except when inserting or

removing cable. The safety plug keeps the port clean and prevents accidental

exposure to laser light.

■Do not bend fiber-optic cable beyond the maximum bend radius. An arc smaller

than a few inches in diameter can damage the cable and cause problems that

are difficult to diagnose.

■Do not let fiber-optic cable hang free from the connector.

■Do not allow fastened loops of cable to dangle, which stresses the cable at the

fastening point.

1. Make sure you have the appropriate cable for the FIC or PIC.

2. If you are connecting to a FIC or PIC with removable transceivers, make sure

the transceiver is installed.

3. If the transceiver is covered by a rubber safety plug, remove the plug.

4. If the cable connector is covered by a rubber safety cap, remove the cap.

5. Insert the appropriate cable connector into the cable connector port on the FIC

or PIC faceplate.

6. Arrange the cable in the cable management system to prevent it from dislodging

or developing stress points. Secure the cable so that it is not supporting its own

weight as it hangs to the floor. Place excess cable out of the way in a neatly

coiled loop in the cable management system. Placing fasteners on the loop helps

to maintain its shape.

Step 5: Connect Ground and Power Cables

NOTE: Connect each power supply to a separate external power source.

The M7i router uses either AC or DC power supplies. Perform the appropriate

procedure for each power supply in your router.

■Connect AC Power on page 10

■Connect DC Power on page 11

Connect AC Power

1. Locate the power cords shipped with the router, which should have a plug

appropriate for your geographical location.

2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and

connect the strap to one of the ESD points on the chassis.
