ACX4000 Universal Access Routers Quick Start

ACX4000 Quick Start Description

This Quick Start contains information you need to install and configure the router quickly.

For complete installation instructions, see the ACX4000 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 20. For a complete list of warnings for this router, including

translations, see the ACX4000 Universal Access Routers Hardware Guide at

http://www.juniper.net/techpubs/.

The ACX Universal Access Router is principally designed for high-density access and

pre-aggregation and is environmentally hardened. The router can be used as a cell site

router or pre-aggregation device for mobile backhaul and a CPE for business or residential

access.

The ACX Series routers support TDM, Gigabit Ethernet, and 10-Gigabit Ethernet interfaces.

The chassis has eight built-in Gigabit Ethernet combination copper or fiber interfaces

with PoE+ (65 W) support on two ports, two Gigabit Ethernet SFP ports, and two

10-Gigabit Ethernet SFP+ ports. The router also has two slots for modular interface cards

(MICs). For a list of the supported MICs, see the ACX4000 Universal Access Router MIC

Guide.

The ACX Series router is a single-board router with a built-in Routing Engine and one

Packet Forwarding Engine that has two Flexible PIC Concentrators (shown in the CLI as

FPC 0 and FPC 1). Because there is no switching fabric, the single Packet Forwarding

Engine takes care of packet forwarding:

•Routing Engine—Provides Layer 3 routing services and network management.

•Packet Forwarding Engine—Performs Layer 2 and Layer 3 packet switching, route

lookups, and packet forwarding.

The ACX Series router is powered by Junos OS, supporting extensive L2 and L3 features,

IP/MPLS with traffic engineering, rich network management, fault management, service

monitoring and Operation, Administration, and Maintenance (OAM) capabilities, and an

open software development kit (SDK) system that allows providers to customize and

integrate operations with their own management systems. For a list of related Junos OS

documentation, see http://www.juniper.net/techpubs/software/junos/.

As part of the mobile backhaul, the ACX Series router at the cell site and the MX Series

router at the aggregation layer provide comprehensive end-to-end Ethernet, MPLS, and

OAM features with the one Junos OS running on both platforms.

The compact routers are 2.5 rack units (U; that is, 4.375 in., or 11.11 cm) tall. Several routers

can be stacked in a single floor-to-ceiling rack for increased port density per unit of floor

space.

ACX4000 Quick Start Description

The chassis is a rigid sheet metal structure that houses all the other router components.

The chassis measures 4.375 in. (11.11 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 in. (48 cm)

(from the front-mounting brackets to the rear of the chassis). The chassis installs in

standard 300-mm deep (or larger) enclosed cabinets, 19-in. equipment racks, or telco

open-frame racks.

ACX4000 Universal Access Routers Quick Start

Step 1: Prepare the Site for ACX4000 Router Installation

Prepare your site for ACX4000 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: 4.375 in. (11.11 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 22.48 lb (10.2 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 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.

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 mounting ship with the router (see Figure 3 on page 7).

Attach both mounting brackets to the front of the chassis:

1. Align the bracket with the three sets of mounting holes.

2. Insert the six screws at the top, middle, and bottom of the bracket and tighten each

partially.

3. Tighten the four screws completely.

4. Repeat the procedure for the other bracket.

Step 2: Install the Router

Install the ACX4000 Router in the Rack

The router can be installed horizontally in a rack or cabinet.

Two people are required to install the ACX4000 router. The chassis weighs approximately

22.48 lb (10.2 kg). To install the chassis (see Figure 4 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.

Step 3: Ground the ACX4000 Router

You must ground the router before connecting power.

•Tools Required to Ground the ACX4000 Router on page 9

•Connect the Grounding Cable on page 9

Tools Required to Ground the ACX4000 Router

To ground the router, you need the following tools:

•Phillips (+) screwdriver, number 2

•ESD grounding wrist strap

•Two SAE 10-32 screws and paint piercing washers (not provided)

•Grounding lug, Panduit LCD06-10-A or equivalent (not provided)

•Grounding cable, minimum 6 AWG (13.3 mm2) 90° C wire (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. 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 electrostatic discharge (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 10).

8. Secure the grounding cable lug with the washers and screws. The holes are sized for

SAE 10-32 screws. Apply 4.34 lb-in (0.49 Nm) of torque to each screw. Do not

overtighten the screw. (Use a number 2 Phillips screwdriver.)

CAUTION: Ensure that each grounding cable lug seats flush against the

surface of the grounding points as you are tightening the screws. Ensure

that each screw is properly threaded into the grounding points. Applying

installation torque to the screw when improperly threaded may result in

damage to the terminal.

Step 3: Ground the ACX4000 Router

CAUTION: The maximum torque rating of the grounding screws on the

router is 4.34 lb-in (0.49 Nm). The grounding screws may be damaged if

excessive torque is applied. Use only a torque-controlled driver to tighten

screws. Use an appropriately sized driver, with a maximum torque capacity

of 5 lb-in. or less. Ensure that the driver is undamaged and properly

calibrated and that you have been trained in its use. You may wish to use

a driver that is designed to prevent overtorque when the preset torque

level is achieved.

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.
