Reinstall Components
1. Slide each component into the chassis evenly so that it does not become stuck
or damaged.
2. Tighten the captive screws for each component.
NOTE: Make sure that all empty slots are covered with a blank panel before operating
the router.
Step 4: Connect External Devices and DPC Cables
To connect external devices and DPC cables, perform the following procedures:
■Connect to a Network for Out-of-Band Management on page 13
■Connect a Management Console on page 14
■Connect the DPC Cables on page 14
Figure 7: Connect External Devices and DPC Cables
Connect to a Network for Out-of-Band Management
1. Turn off the power to the management device.
2. Plug one end of the RJ-45 Ethernet cable into the ETHERNET port on the Routing
Engine.
Step 4: Connect External Devices and DPC Cables ■13
Step 4: Connect External Devices and DPC Cables

3. Plug the other end of the cable into the network device.
Connect a Management Console
1. Turn off the power to the management device.
2. Plug one end of the RJ-45 Ethernet cable into the CONSOLE or AUX port on the
Routing Engine.
3. Plug the female DB-9 end into the device's serial port.
Connect the DPC Cables
1. Have ready a length of the type of cable used by the DPC. For cable specifications,
see the MX-series Ethernet Services Router DPC Guide.
2. If the DPC 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 cables. 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.
3. Insert the cable connector into the cable connector port on the DPC faceplate.
4. 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.
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.

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 MX960 Ethernet Services Router Hardware Guide at
http://www.juniper.net/techpubs/hardware/.
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.
Safety Warnings ■19
Safety Warnings

■Only trained and qualified personnel should install or replace the router.
■Perform only the procedures described in this quick start or the MX960 Ethernet
Services 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 MX960
Ethernet Services 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 6 in. (15.2 cm) of clearance between side-cooled
routers. Allow 2.8 in. (7 cm) between the side of the chassis and any
non-heat-producing surface such as a wall.
■When installing the router, do not use a ramp inclined more than 10 degrees.
■Manually installing the router requires three to lift. Before lifting the chassis,
remove components and attach the installation handle as described in the MX960
Ethernet Services Router Hardware Guide. To prevent injury, keep your back
straight and lift with your legs, not your back. Do not attempt to lift the chassis
by the power supply handles.
■The router should be mounted at the bottom of the rack if it is the only unit in
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.
■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 power supply using the appropriate lugs. When connecting power,
the proper wiring sequence is ground to ground, +RTN to +RTN, then –48 V
to –48 V. When disconnecting 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.
