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.

ACX2000 Universal Access Routers Quick Start

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.
