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.

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

specifications, see the ACX2000 Universal Access Routers Hardware Guide.
NOTE: Shielded cables are required for outside deployment.
2. Remove the rubber safety plug from the cable connector port.
WARNING: Do not look directly into a fiber-optic transceiver or into the
ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable
connected to a transceiver emit laser light that can damage your eyes.
CAUTION: Do not leave a fiber-optic transceiver uncovered except when
inserting or removing cable. The safety cap keeps the port clean and
prevents accidental exposure to laser light.
3. Insert the cable connector into the cable connector port on the faceplate.
4. Arrange the cable to prevent it from dislodging or developing stress points. Secure
the cable so that it is not supporting its own weight as it hangs to the floor. Place
excess cable out of the way in a neatly coiled loop.
CAUTION: Avoid bending fiber-optic cable beyond its minimum bend
radius. An arc smaller than a few inches in diameter can damage the cable
and cause problems that are difficult to diagnose.
CAUTION: Do not let fiber-optic cable hang free from the connector. Do
not allow fastened loops of cable to dangle, which stresses the cable at
the fastening point.

Step 5: Connect Power to the ACX2000 Router
WARNING: You must ground the router before connecting the power cables.
•Tools Required to Connect Power to the ACX2000 Router on page 12
•Connect Power Cables on page 12
Tools Required to Connect Power to the ACX2000 Router
To connect power to the router, you need the following tools:
•Phillips (+) screwdriver, number 2
•ESD grounding wrist strap
•M3 screws and flat washers
•DC power source cables, minimum 14 AWG or as required by local code (not provided)
•Ring lugs, Molex 190700067 or equivalent, (not provided)
Connect Power Cables
The DC power supply has four terminals on the front panel, covered by a clear plastic
cover.
WARNING: You must ground the router before connecting the DC power
cables.
Table 1: ACX2000 DC Power System Input Voltage
SpecificationNominal Voltage
Operating range: +18 to +30 VDC+24
Operating range: –39 to –56 VDC–48
Operating range: –39 to –72 VDC–60
1. Switch off the dedicated customer site circuit breakers. Ensure that the voltage across
the DC power source cable leads is 0 V and that there is no chance that the cable
leads might become active during installation.
2. Remove the clear plastic cover protecting the terminal on the faceplate.
3. Verify that the DC power cables are correctly labeled before making connections to
the power supply. In a typical power distribution scheme where the return is connected
to chassis ground at the battery plant, you can use a multimeter to verify the resistance
of the –48V and RTN DC cables to chassis ground:
Copyright © 2016, Juniper Networks, Inc.12
ACX2000 Universal Access Routers Quick Start

•The cable with very large resistance (indicating an open circuit) to chassis ground
is –48V.
•The cable with very low resistance (indicating a closed circuit) to chassis ground is
RTN.
4. Remove the screws and flat washers from the terminals.
5. Secure each power cable lug to the terminal with the flat washers and screw (see
Figure 8 on page 14). Apply between 8 lb-in. (0.9 Nm) and 9 lb-in. (1.02 Nm) of torque
to each screw. Do not overtighten the screw. (Use a number 2 Phillips screwdriver.)
a. Secure the positive (+) DC source power cable lug to the RTN (return) terminal.
b. Secure the negative (–) DC source power cable lug to the –48V (input) terminal.
CAUTION: Ensure that each power cable lug seats flush against the surface
of the terminal block as you are tightening the screws. Ensure that each
screw is properly threaded into the terminal. Applying installation torque
to the screw when improperly threaded may result in damage to the
terminal.
CAUTION: The maximum torque rating of the terminal screws on the DC
power supply is 9 lb-in. (1.02 Nm). The terminal screws may be damaged
if excessive torque is applied. Use only a torque-controlled driver to tighten
screws on the DC power supply terminals. Use an appropriately-sized
driver, with a maximum torque capacity of 9 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.
6. Replace the clear plastic cover over the terminals on the faceplate.
7. 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.
8. Connect each DC power cable to the appropriate external DC power source.
NOTE: For information about connecting to external DC power sources,
see the instructions for your site.
9. Switch on the external circuit breakers to provide voltage to the DC power source
cable leads. Observe the system LED on front of the router. If the DC power cable is
correctly installed and functioning normally, the system LED lights green steadily. If
the status LED indicates that the power supply is not functioning normally, repeat the
installation and cabling procedures.
