21.

Insert sixteen mounting screws (eight on each side) into the mounting holes to secure the router to the rack.

22.

Visually inspect the alignment of the router. To verify that the router is installed properly in the rack, see that all the mounting screws on one side of the rack are aligned with the mounting screws on the opposite side and the router is level.

23.

Reassemble the router transport kit, and set aside.

Step 4: Connect the Grounding Cable

Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to an approved site ESD grounding point. See the instructions for your site.

Connect the grounding cable to a proper earth ground.

Verify that a licensed electrician has attached the cable lug provided with the router to the grounding cable.

Make sure that grounding surfaces are clean and brought to a bright finish before you make grounding connections.

Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis. For more information about ESD, see the MX2020 3D Universal Edge Router Hardware Guide.

Place the grounding cable lug over the grounding points. The upper pair is sized for

UNC 1/4-20 bolts, and the lower pair is sized for M6 bolts.

Secure the grounding cable lug to the grounding points, first with the washers, and then with the nuts (see

Figure 30 on page 43 ).

Figure 30: Grounding Points on the MX2020 Router

Verify that the grounding cabling is correct, that the grounding cable does not touch or block access to router components, and that it does not drape where people could trip on it.

MX2020 3D Universal Edge Router Quick Start

Step 5: Reinstall Components

To reinstall the components in the router:

Take each component out of its electrostatic bag, and identify the slot on the component where it will be connected.

NOTE: Remove the shipping covers before installing router components.

Slide each component into the chassis evenly so that it does not become stuck or damaged.

NOTE: We recommend reinstalling the rear components first.

Tighten the captive screws, and secure all levers for each component.

NOTE: Make sure that all empty slots are covered with a blank panel before operating the router.

MX Series Interface Module Reference

If the cable connector port is covered by a rubber safety plug, remove the plug.

MX2020 3D Universal Edge Router Quick Start

WARNING: Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to a transceiver emit laser light that can damage your eyes.

CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

Insert the cable connector into the cable connector port on the faceplate.

Arrange the cable in the cable management system to prevent it from dislodging or developing stress points. Secure the cable so that it does not support 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.

CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

CAUTION: 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.

Step 7: Connect Power Cables

Depending on your configuration, your router uses either AC or DC power distribution modules (PDMs). Perform the appropriate procedures for each PDM in your router. For more information about PDMs, see the MX2020 3D Universal Edge Router Hardware Guide.

CAUTION: Do not mix AC and DC power modules within the same router.

For more information about configuring the backup routing and static routes, see the

Junos OS Administration Library for Routing Devices.

Configure the name of the router. If the name includes spaces, enclose the name in quotation marks (“ ”).

[edit] root# set system host-name host-name

NOTE: The DNS server does not use the hostname to resolve to the correct

IP address. This hostname is used to display the name of the Routing

Engine in the CLI. For example, the following hostname appears on the command-line prompt when the user is logged in to the CLI:

user-name@host-name>

Configure the IP address of the DNS server.

[edit] root# set system name-server address

Configure the router’s domain name.

[edit] roott# set system domain-name domain-name

Configure the IP address and prefix length for the router’s management Ethernet interface.

[edit] root # set interfaces fxp0 unit 0 family inet address address/prefix-length

Configure the IP address of a backup Routing Engine. The backup Routing Engine is used while the local router is booting and if the routing process fails to start. After the routing process starts, the backup Routing Engine address is removed from the local routing and forwarding tables.

[edit] root# set system backup-router address

(Optional) Configure the static routes to remote subnets with access to the management Ethernet port. Access to the management Ethernet port is limited to the local subnet. To access the management Ethernet port from a remote subnet, you must add a static route to that subnet within the routing table.

Safety Warnings

WARNING: See installation instructions before connecting the router. This is a summary of safety warnings. For a complete list of warnings for this router, including translations, see the MX2020 3D Universal Edge Router

Hardware Guide at http://www.juniper.net/techpubs/

WARNING: The intrabuilding port(s) of the router is suitable for connection to intrabuilding or unexposed wiring or cabling only. The intrabuilding port(s) of the router MUST NOT be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intrabuilding interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue

4) and require isolation from the exposed OSP cabling. The addition of primary protectors is not sufficient protection to connect these interfaces metallically to OSP wiring.

CAUTION: Before removing or installing components of a router, attach an

ESD strap to an ESD point and place the other end of the strap around your bare wrist. Failure to use an ESD strap could result in damage to the router.

CAUTION: Use an external surge protective device (SPD) at the AC input of the router.

•

Only trained and qualified personnel should install or replace the router.

•

Perform only the procedures described in this Quick Start or in the MX2020 3D Universal

Edge Router Hardware Guide. Other services should be performed by authorized service personnel only.

•

Read the installation instructions before you connect the router to a power source.

•

Before installing the router, read the guidelines for site preparation in the MX2020 3D

Universal Edge Router Hardware Guide to make sure that the site meets power, environmental, and clearance requirements for the router.

•

For the cooling system to function properly, the airflow around the chassis must be unrestricted. Allow at least 36 in. (91.44 cm) of clearance between front to rear-cooled routers. Allow 2.8 in. (7 cm) between the side of the chassis and any non-heat-producing surface such as a wall.

•

Four people are required to move the MX2020 router.

•

Always remove the front and rear shipping covers before removing the components.

MX2020 3D Universal Edge Router Quick Start

•

Always remove all components before moving the router. The empty router weighs

330 lb (149.68 kg).

• When installing the router, do not use a ramp inclined more than 10 degrees.

•

Measure the shipping container to make sure there is adequate clearance through doorways and passages to accommodate the dimensions.

NOTE: The shipping container (wooden crate) is 85.1 in. (216.15 cm) high,

48 in. (121.92 cm) deep, and 42 in. (106.68 cm) wide.

•

Always reinstall the front and rear shipping covers to help move the router.

CAUTION: The shipping covers help prevent damage to the card cage and backplanes during rack installation.

•

When installing components into the router, load the chassis from the bottom to the top.

• After installing components, install the EMI covers over the line and system cards.

•

If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the router in the rack.

• When removing or installing an electrical component, always place it component-side up on a flat antistatic surface or in an electrostatic bag.

•

When you install the router, always make the ground connection first and disconnect it last.

• Wire the DC PDMs using the appropriate lugs. When you connect power, the proper wiring sequence is ground to ground, +RTN to +RTN, then –48 V to –48 V. When you disconnect power, the proper wiring sequence is –48 V to –48 V, +RTN to +RTN, then ground to ground. Always connect the ground wire first and disconnect it last.

• Do not work on the system or connect or disconnect cables during electrical storms.

• Before working on equipment that is connected to power lines, remove jewelry, including rings, necklaces, and watches. Metal objects heat up when connected to power and ground and can cause serious burns or become welded to the terminals.

• Failure to observe these safety warnings can result in serious physical injury.

• AC power cable warning (Japan):
