MX960 Ethernet Services 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 MX960 Ethernet Services Router
Hardware Guide at http://www.juniper.net/techpubs/.
WARNING: This Quick Start contains a summary of safety warnings in “Safety
Warnings”on page 19. 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/.
The MX960 router is 16 rack units (RU) tall. Three routers can be stacked in a single
floor-to-ceiling rack, for increased port density per unit of floor space. The router
provides 14 slots that can be populated with up to 12 interface cards and two Switch
Control Boards (SCBs) in nonredundant fabric configurations. The MX960 Services
Router is an Ethernet-optimized edge router that provides both switching and
carrier-class Ethernet routing. The MX960 router has a capacity of up to 480 gigabits
per second (Gbps), full duplex.
Fully populated, the MX960 provides up to 480 Gigabit Ethernet or up to 48 10-Gigabit
Ethernet ports. Two types of Dense Port Concentrator (DPC) interface cards are
available, both of which consist of consist of four Packet Forwarding Engines and
enable a throughput of 10 Gbps:
■A 40-port Gigabit Ethernet DPC with SFP connectors (1000 Mbit copper and fiber
only).
■A 4-port 10-Gigabit Ethernet DPC with XFP connectors.
The router is shipped in a cardboard box strapped securely to a wooden pallet. Plastic
straps secure the top and bottom in place. The router chassis is bolted to this pallet.
Quick Start installation instructions and a cardboard accessory box are also included
in the shipping container.

Quick Start Description
Step 1: Prepare the Site
Figure 1: Rack Clearance and Router Dimensions
Rack-Mounting Requirements
■You can install the router in a four-post rack or cabinet or an open-frame rack.
■The rack rails must be spaced widely enough to accommodate the router chassis's
external dimensions: 27.75 in. (70.49 cm) high, 23.0 in. (58.42 cm) deep, and
4■Step 1: Prepare the Site
MX960 Ethernet Services Router Quick Start
17.37 in. (44.11 cm) wide. The outer edges of the mounting brackets extend the
width to 19 in. (48.3 cm).
■The rack must be strong enough to support the weight of the fully configured
router, up to 350 lb (158.76 kg). If you stack three fully configured routers in
one rack, it must be capable of supporting about 1,050 lb (476.3 kg).
■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
30 in. (76.2 cm) in front of the router and 24 in. (61 cm) behind the router.
■The rack or cabinet must have an adequate supply of cooling air.
■Ensure that the cabinet allows the chassis hot exhaust air to exit from the cabinet
without recirculating into the router.
■The router must be installed into a rack that is secured to the building structure.
■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.
Tools Required
To unpack the router and prepare for installation, you need the following tools:
■A mechanical lift—recommended
■Phillips (+) screwdrivers, numbers 1 and 2
■2.5 mm flat-blade (–) screwdriver
■3/8-in. nut driver
■1/2-in. or 13-mm open-end or socket wrench to remove bracket bolts from the
shipping pallet
■Electrostatic discharge wrist strap
■Antistatic mat
Step 1: Prepare the Site ■5
Step 1: Prepare the Site
Step 2: Install the Mounting Hardware
To install the mounting hardware in a four-post rack or cabinet or an open-frame
rack, perform one of the following procedures:
■Install the Mounting Hardware in a Four-Post Rack or Cabinet on page 6
■Install the Mounting Hardware in an Open-Frame Rack on page 7
Install the Mounting Hardware in a Four-Post Rack or Cabinet
To install the mounting shelf, follow this procedure:
1. On the front rack rails, install cage nuts in the holes specified in the MX960
Ethernet Services Router Hardware Guide for the large shelf and the spacer bars.
2. On the front of each front rack rail, partially insert a mounting screw into the
hole containing the lowest cage nut.
3. Install the large shelf on the front rack rails. Rest the bottom slot of each ear on
a mounting screw.
4. Partially insert a mounting screw into the top hole in each ear of the large shelf.
5. Tighten all the screws completely.
6. On the rear rack rails, install cage nuts in the holes specified in the MX960
Ethernet Services Router Hardware Guide for the small shelf.
7. On the back of each rear rack rail, partially insert a mounting screw into the hole
containing the lowest cage nut.
8. Install the small shelf on the back rack rails. Rest the bottom slot of each ear on
a mounting screw. The small shelf installs on the back of the rear rails, extending
toward the center of the rack. The bottom of the small shelf should align with
the bottom of the large shelf.
9. Partially insert screws into the open holes in the ears of the small shelf.
10. Tighten all the screws completely.
6■Step 2: Install the Mounting Hardware

Install the Mounting Hardware in an Open-Frame Rack
To install the mounting shelf, follow this procedure:
1. On the rear of each rack rail, partially insert a mounting screw into the highest
hole specified in the MX960 Ethernet Services Router Hardware Guide for the large
shelf.
2. Install the large shelf on the rack. Hang the shelf over the mounting screws using
the keyhole slots located near the top of the large shelf flanges.
3. Partially insert screws into the open holes in the ears of the large shelf.
4. Tighten all the screws completely.

Step 3: Install the Router
Because of the router's size and weight, we recommend you install the router using
a mechanical lift. The procedure for installing the router depends on whether you
use a mechanical lift:
■Install the Router Using a Lift on page 8
■Install the Router Without a Mechanical Lift on page 10
Install the Router Using a Lift
To install the router using a lift:
1. Ensure the rack is in its permanent location and is secured to the building. Ensure
that the installation site allows adequate clearance for both airflow and
maintenance. For details, see the MX960 Ethernet Services Router Hardware Guide.
2. Load the router onto the lift, making sure it rests securely on the lift platform
(see Figure 4 on page 9).
8■Step 3: Install the Router
MX960 Ethernet Services Router Quick Start
Figure 4: Load the Router onto the Lift
3. Using the lift, position the router in front of the rack or cabinet, centering it in
front of the mounting shelves.
4. Lift the chassis approximately 0.75 in. above the surface of the mounting shelves
and position it as close as possible to the shelves.
5. Carefully slide the router onto the mounting shelves so that the bottom of the
chassis and the mounting shelves overlap by approximately two inches.
6. Slide the router onto the mounting shelves until the mounting brackets or
front-mounting flanges contact the rack rails. The shelves ensure that the holes
in the mounting brackets and the front-mounting flanges of the chassis align
with the holes in the rack rails.
7. Move the lift away from the rack.
8. To install the router in an open-frame rack, install a mounting screw into each
of the open mounting holes aligned with the rack, starting from the bottom.
9. Visually inspect the alignment of the router. If the router is installed properly in
the rack, all the mounting screws on one side of the rack should be aligned with
the mounting screws on the opposite side and the router should be level.

Step 3: Install the Router
Install the Router Without a Mechanical Lift
To install the router without a mechanical lift, perform all of the following procedures:
■Remove Components on page 11
■Lift the Router into the Rack on page 12
■Reinstall Components on page 13
