ACX2000 Universal Access Routers Quick Start

ACX2000 Quick Start Description
This Quick Start contains information you need to install and configure the router quickly.
For complete installation instructions, see the ACX2000 Universal Access Routers Hardware
Guide at http://www.juniper.net/techpubs/.
WARNING: This Quick Start contains a summary of safety warnings in “Safety
Warnings” on page 18. For a complete list of warnings for this router, including
translations, see the ACX2000 Universal Access Routers Hardware Guide at
http://www.juniper.net/techpubs/.
The ACX2000 Universal Access Router is an Ethernet-optimized mobile backhaul router
that provides both switching and carrier-class Ethernet routing. The ACX2000 router
enables 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 router has high-density
Ethernet interfaces and high-capacity switching throughput.
The ACX2000 router is a single-board router 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 both ingress and egress packet forwarding.
The ACX2000 router is a compact gateway router that is one rack unit (U) tall. Several
gateway routers can be stacked in a single floor-to-ceiling rack for increased port density
per unit of floor space.
The ACX2000 router contains 16 T1 and E1 ports, 6 Gigabit Ethernet ports, and 2 PoE
ports. The ACX2000 router also supports installation of two Gigabit Ethernet SFP
transceivers and two 10-Gigabit Ethernet SFP+ transceivers.

ACX2000 Quick Start Description

Step 1: Prepare the Site for ACX2000 Installation
Prepare your site for ACX2000 installation by observing the following guidelines:
•You can install the gateway 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).
•Two people are required to install the ACX2000 router. 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.
•The router must be installed 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 ACX2000 Router in the Rack on page 7
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 2 on page 6 and Figure 3 on page 6).
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 ACX2000 Router in the Rack
The router can be installed horizontally in a rack or cabinet.
NOTE: For additional installation options, contact JTAC.
Two people are required to install the ACX2000 router. The chassis weighs approximately
7 lb (3.2 kg). To install the chassis (see Figure 4 on page 7):
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.

Step 3: Ground the ACX2000 Router
You must ground the router before connecting power.
•Tools Required to Ground the ACX2000 Router on page 8
•Connect the Grounding Cable on page 8
Tools Required to Ground the ACX2000 Router
To ground the router, you need the following tools:
•Phillips (+) screwdriver, number 2
•ESD grounding wrist strap
•Two SAE 10-32 screws and flat washers (not provided)
•Grounding lug, Panduit LCD6-14BH-L or equivalent (not provided)
•Grounding cable, minimum 16 AWG (1.31 mm2) 90° C wire (not provided) for AC systems
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. 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 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.
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.
5. Detach the ESD grounding strap from the site ESD grounding point.
6. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
7. Place the grounding cable lug over the grounding points on the front of the chassis
(see Figure 5 on page 9).
8. Secure the grounding cable lug with the washers and screws. The holes are sized for
SAE 10-32 screws.
9. Dress the grounding cable and verify that it does not touch or block access to router
components, and that it does not drape where people could trip on it.
