This Quick Start contains information you need to install and configure the router quickly. For complete
installation instructions, see the MX104 Universal Routing Platform Hardware Guide at

WARNING: This Quick Start contains a summary of safety warnings in “Safety
Warnings” on page 25. For a complete list of warnings for this router, including
translations, see the MX104 Universal Routing Platform Hardware Guide at
https://www.juniper.net/documentation/.
The router is environmentally hardened and is 3.5 rack units (U; that is 6.125 in., or 15.55 cm) tall. Several
routers can be stacked in a single floor-to-ceiling rack, for increased port density per unit of floor space.
The chassis installs in standard 11.81 in. (30 cm)-deep (or larger) enclosed cabinets, 19-in. equipment racks,
or telco open-frame racks.

Step 1: Prepare the Site for MX104 Router Installation
Prepare your site for MX104 installation by observing the following guidelines:
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 chassis's external dimensions: 6.125
•
in. or (15.55 cm) high, 9.5 in. (24.13 cm) deep, and 17.5 in. (44.5 cm) wide. The outer edges of the
mounting brackets extend the width to 19.2 in. (48.7 cm).
One person must be available to lift the router while another secures the router to the rack.
•
The rack must be strong enough to support the weight of the fully configured router, up to 32 lb (14.5 kg).
•
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 devices. 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 30 in. (76.2 cm) in front of the router and 24 in. (61 cm)
behind the router.
5
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.
You must install the router into a rack that is secured to the building structure.
•
Mount the router 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.
Install the router only in restricted areas, such as dedicated equipment rooms and equipment closets, in
•
accordance with Articles 110-16, 110-17, and 110-18 of the National Electrical Code, ANSI/NFPA 70.

Install the MX104 Router in the Rack
The router can be installed horizontally in a rack or cabinet.
Two people are required to install the MX104 router. The chassis weighs approximately 32 lb (14.5 kg).
To install the chassis (see Figure 3 on page 8):
1. Ensure that 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.
2. Position the router in front of the rack or cabinet.
3. Have one person grasp both sides of the router, lift the router, and position it in the rack, aligning the
mounting bracket holes with the threaded holes in the rack rails. Make sure the chassis is level.
4. Have the second person install a mounting screw into each of the open mounting holes aligned with
the rack, starting from the bottom.
5. 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.

Tools Required to Ground the MX104 Router
To ground the router, you need the following tools:
Phillips (+) screwdriver, number 2
•
9
ESD grounding wrist strap
•
Two SAE 10-32 screws and washers
•
Grounding lug, Panduit LCD10-10-L
•
Grounding cable, use 14-AWG (2.08 mm2) 90°C wire for AC (not provided)
•
Grounding cable, use 6-AWG (13.3 mm2) 60°C wire for 24V DC (not provided)
•
Connect the Grounding Cable
You ground the router by connecting a grounding cable to earth ground and then attaching it to the chassis
grounding points on the front of the router. To ground the router:
1. Verify that a licensed electrician has attached the cable lug provided with the router to the grounding
cable.
2. Attach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an approved
site ESD grounding point. See the instructions for your site.
3. Ensure that all grounding surfaces are clean and brought to a bright finish before grounding connections
are made.
4. Connect the grounding cable to a proper earth ground.
