The MX2008 3D Universal Edge Router is shipped in a wooden crate. A wooden pallet forms the base of the crate. The MX2008 chassis is bolted to this pallet. The shipping crate also contains a large rack mount tray, electromagnetic interference (EMI) cover, a cardboard accessory box, and a Quick Start (this document).

NOTE: The shipping container and router (fully populated) weighs approximately 1343 lb (609.17 kg), depending on your configuration.

The MX2008 3D Universal Edge Router with standard cable managers and EMI cover measures 42 in. (106.68 cm) high, 19 in. (48.26 cm) wide, and 30.90 in. (78.49 cm) deep

(from the front-mounting flanges to the rear of the chassis). An extended cable manager extends the total depth to 36.82 in. (93.53 cm).

One router can be installed in a 24-U or taller open-frame or four-post rack if the rack can support the combined weight, which can be greater than 664.8 lb (301.55 kg).

NOTE:

• The dimensions also include the cable managers and EMI cover.

• If you are installing the MX2008 router into a network cabinet, make sure that no hardware, device, rack, or cabinet components obstruct the 24-U rack space from access during installation.

The MX2008 router is 24 rack units (U) tall. One router can be installed in an open-frame rack, four-post rack, or cabinet. The MX2008 router has 10 dedicated line-card slots, which means a maximum of 10 Modular Port Concentrators (MPCs) including Adapter cards and Modular Interface Cards (MICs) can be installed on MX2008. ADCs provide housing to MPCs. The MPCs attach to the adapter cards, which in turn connect to the backplane. Up to 2 MICs can be installed in each MPC. Fully populated, the MX2008 router supports up to 20 MICs. The MX2008 host subsystem consists of two Routing and Control Boards (RCBs). The RCB is an integrated board and a single FRU that provides

Routing Engine and Control Board functionality and supports virtualization. The router contains 8 SFBs that provide 7+1 redundancy.

Rack-Mounting Requirements

• You can install the router in an open-frame rack, a four-post rack, or a cabinet.

NOTE: The shipping and installation site must be an electrostatic discharge

(ESD)-approved area.

• The rack rails must be spaced widely enough to accommodate the chassis’s external dimensions: 42 in. (106.68 cm) high, 19 in. (48.26 cm) wide, and 30.90 in. (78.49 cm) deep (measured from the front of cable manager to the rear of the chassis). An extended cable manager extends the total depth to 36.82 in. (93.53 cm) (measured from the front of cable manager to the rear of the chassis). See

Figure 1 on page 6

and

Figure 2 on page 7 .

In an open-frame rack, center-mounting is required to provide an even distribution of weight for greater stability. For center-mounting, use the mounting brackets attached to the center of the chassis for rack mounting.

• The rack must be strong enough to support the weight of the fully configured router, up to 742.2 lb (336.66 kg) for AC chassis, and 664.8 lb (301.55 kg) for DC chassis.

• 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.

• For service personnel to remove and install hardware components, there must be adequate space at the front and back of the router. Allow at least 36 in. (91.44 cm) in front of the router and 36 in. (91.44 cm) behind the router.

• The rack or cabinet must have an adequate supply of cooling air.

• Ensure that the cabinet allows the hot exhaust air of the chassis to exit from the cabinet without recirculating into the router.

• The router must have the shipping covers installed to help move the router into the rack or cabinet.

• The router must be installed into a rack or cabinet that is secured to the building structure.

• The cabinet must be clear of any hardware, device, rack, or cabinet component that obstructs the 24-U rack space from being accessed during installation.

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 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 MX2008 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 32 on page 41 ).

Figure 32: Grounding Points on the MX2008 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.

MX2008 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.

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.

Turn off the power to the management device.

Plug one end of an RJ-45 Ethernet cable into the ETHERNET port on the RCB.

Plug the other end of the cable into the network device.

CAUTION: You must use shielded cables for the following ports: console, management, auxiliary, USB, and clocking ports.

Connect a Management Console

Turn off the power to the management device.

Plug one end of an RJ-45 Ethernet cable into the CONSOLE or AUX port on the RCB.

MX2008 3D Universal Edge Router Quick Start

Plug the female DB-9 adapter end of the cable into the device's serial port.

CAUTION: You must use shielded cables for the following ports: console, management, auxiliary, USB, and clocking ports.

Connect the Line Card Cables

Have ready a length of the type of cable used by the MPCs or MICs. For cable specifications, see the MX Series Interface Module Reference .

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

WARNING: Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cable. Fiber-optic transceivers and fiber-optic cable 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 manager 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 manager 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 MX2008 3D Universal Edge Router Hardware Guide .

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 MX2008 3D Universal Edge Router

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

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: To comply with intrabuilding lightning and surge requirements, intrabuilding wiring must be shielded, and the shield for the wiring must be grounded at both ends.

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 MX2008 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 MX2008 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

Safety Warnings 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 MX2008 router.

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

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

261 lb (118.39 kg).

• When installing the router, do not incline the chassis 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 66.25 in. (168.27 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.

WARNING: 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 cover over the line 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 by 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):
