ACX500 Universal Access Routers Quick Start—ACX500 Indoor Routers

ACX500 Routers Quick Start Description

This Quick Start contains information you need to install and configure the ACX500

indoor router quickly. For complete installation instructions, see the ACX500 Universal

Access Router Hardware Guide at http://www.juniper.net/techpubs/.

WARNING: This Quick Start contains a summary of safety warnings in “Safety

Warnings” on page 21. For a complete list of warnings for this router, including

translations, see the ACX500 Universal Access Router Hardware Guide at

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

The ACX Series Universal Access 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, mobile backhaul service cell site deployment, and service

provider or operator cell site deployment. The routers have high-density Ethernet

interfaces and high-capacity switching throughput.

An ACX Series router has 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 ACX500 indoor router is 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 chassis is a rigid sheet metal structure that houses all the

other router components. The chassis of the ACX500 indoor router measures 1.75 in.

(4.45 cm) high, 9.4 in. (24 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) (with mounting brackets

attached). The chassis installs in standard 300-mm deep (or larger) enclosed cabinets,

19-in. equipment racks, or telco open-frame racks. The ACX500 indoor router is available

in both AC and DC models.

The ACX500 indoor router contains a total of 10 Gigabit Ethernet ports, eight of which

are labeled COMBO. At any point of time, you can use a maximum of six ports.

The ports labeled COMBO (combination ports) consist of four RJ-45 ports and four

Gigabit Ethernet SFP ports. Out of the four RJ-45 ports, three ports support PoE (PoE+

and PoE++).

The two ports that are not part of the COMBO ports are the Gigabit Ethernet SFP ports.

On the ACX500, the six ports that you can use at any point of time can be two Gigabit

Ethernet SFP ports (non-combination) and four ports from the COMBO ports.

ACX500 Routers Quick Start Description

NOTE: You can mix and match the four RJ-45 and SFP COMBO ports as long

as the port numbers are unique.

For example, from the COMBO ports, you can use the SFP port 0/1/0 along

with the RJ-45 port 0/1/1 PoE+, but not the RJ-45 port 0/1/0 PoE++, because

the port numbers of the SFP and the RJ-45 ports are the same (0/1/0).

ACX500 Routers Quick Start Description

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 in an open-frame rack.

•The rack rails must be spaced widely enough to accommodate the chassis's external

dimensions: 1.75 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). See

Figure 3 on page 7.

•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 8.6 lb (3.9 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. Allow a minimum of

1 meter per second of airflow over the ACX500 indoor router.

•Ensure that the cabinet allows the hot exhaust air of the chassis to exit from the cabinet

without recirculating into the router.

•When deploying the router in environments where the router might operate between

68° F (20° C) and 149° F (65° C), allow a 1 U gap above and below the router.

•When you are installing the router in a cabinet, ensure that the bottom of the cabinet

is closed.

•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 ACX500 Indoor Router in a Rack

The ACX500 indoor router can be installed horizontally in a rack or cabinet. The router

can be accessed only from the front of the router. All components—such as ports, LEDs,

power unit, and so on are located in the front of the ACX500 indoor router.

One person must be available to lift the router while another secures the router to the

rack. The chassis weighs approximately 8.6 lb (3.9 kg). To install the chassis (see

Figure 6 on page 9):

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 that 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 ACX500 Indoor Router

You must ground both the AC-powered and the DC-powered routers before connecting

them to power.

•Tools Required to Ground the Router on page 10

•Connect the Grounding Cable on page 10

Tools Required to Ground the Router

To ground the router, you need the following tools:

•Phillips (+) screwdriver, number 2

•Electrostatic discharge (ESD) grounding wrist strap

•Two SAE 10-32 screws 0.25–0.5 in. long, and flat washers (not provided)

•Grounding lug, Panduit LCD6-14BH-L or equivalent (not provided)

•Grounding cable, minimum 14 AWG (2 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 ACX500 indoor router:

1. Verify that a licensed electrician has attached the cable lug, which is 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 you

make grounding connections.

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 7 on page 11).

NOTE: The grounding point location on the ACX500 is the same for both

the AC and the DC models.

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.
