ACX2000 and ACX2100 Quick Start Description
This Quick Start contains information you need to install and configure the router quickly. For complete
installation instructions, see the ACX2000 and ACX2100 Universal Access Routers Hardware Guide at
https://www.juniper.net/documentation/.
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
ACX2000 and ACX2100 Universal Access Routers Hardware Guide at
https://www.juniper.net/documentation/.
The ACX Universal Metro Routers are Ethernet-optimized mobile backhaul routers that provide both
switching and carrier-class Ethernet routing. The ACX Series routers enable a wide range of business and
residential applications and services, including microwave cell site aggregation, MSO mobile backhaul
service cell site deployment, and service provider or operator cell site deployment. The ACX2000 routers
have high-density Ethernet interfaces and high-capacity switching throughput.
The routers are single-board routers with a built-in Routing Engine and one Packet Forwarding Engine.
The Packet Forwarding Engine has one “pseudo” Flexible PIC Concentrator (FPC 0). Because there is no
switching fabric, the single Packet Forwarding Engine takes care of packet forwarding.
The compact routers are one rack unit (U; that is, 1.75 in., or 4.45 cm) tall. Several routers can be stacked
in a single floor-to-ceiling rack for increased port density per unit of floor space.
The ACX2000 router contains sixteen T1/E1 ports and eight copper Gigabit Ethernet ports. The ACX2000
router also contains two ports for installing Gigabit Ethernet SFP and two ports for installing 10-Gigabit
Ethernet SFP+ transceivers.
The ACX2100 router contains sixteen T1/E1 ports, and four copper Gigabit Ethernet ports. The ACX2100
router also contains two ports for installing Gigabit Ethernet SFP transceivers and two ports for installing
10-Gigabit Ethernet SFP+ transceivers. The ports labeled COMBO PORTS provide an additional four
copper Gigabit Ethernet ports or four Gigabit Ethernet SFP ports. You can only use one set of combination
ports at a time.

Figure 3 on page 5 show the front panel of the AC-powered and DC-powered ACX2100 routers.

Step 1: Prepare the Site for Installation
Prepare your site for 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: 1.7 in.
(4.4 cm) high, 9.4 in. (24 cm) deep, and 17.5 in. (44 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 7 lb (3.2 kg).
•For service personnel to remove and install hardware components, allow at least 2.16 in. (5.5 cm) in
front of 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.
•When deploying the router in environments where the router may operate between 131° F (55° C) and
149° F (65° C), allow a 1 rack unit (U) gap above and below the router.
•When installing the router in a cabinet, ensure that the bottom of the cabinet is closed and there is no
opening.
•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.

Tools Required to Install the Router in a Rack
To install the router in a rack, you need the following tools:
•Phillips (+) screwdriver, number 2
•ESD grounding wrist strap
Install the Mounting Brackets
Two mounting brackets for front or rear mounting ship with the router (see Figure 5 on page 9 and
Figure 6 on page 9).
Attach both mounting brackets to either the front or rear of the chassis:
1. Align the bracket with the two sets of mounting holes.
2. Insert the four screws at the top and bottom of the bracket and tighten each partially.
3. Tighten the four screws completely.
4. Repeat the procedure for the other bracket.

Install the ACX Series Router in the Rack
The router can be installed horizontally in a rack or cabinet.
NOTE: For additional installation options, contact JTAC.
One person must be available to lift the router while another secures the router to the rack. The chassis
weighs approximately 7 lb (3.2 kg). To install the chassis (see Figure 7 on page 10):
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.
9
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.
