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.

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

Step 4: Connect External Devices and Cables

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.

ACX4000 Universal Access Routers Quick Start

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
the strap to one of the ESD points on the chassis. For more information about ESD,
see the ACX4000 Universal Access Routers Hardware Guide.
2. 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.
3. Remove the plastic cover protecting the terminal on the faceplate.
4. 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 return DC cables to chassis ground:
For –48V and –60V:
a. The cable with very large resistance (indicating an open circuit) to chassis ground
is the DC input cable (–).
b. The cable with very low resistance (indicating a closed circuit) to chassis ground
is the return cable (+).
For +24V:
a. The cable with very low resistance (indicating a closed circuit) to chassis ground
is the DC input cable (–).
b. The cable with very large resistance (indicating an open circuit) to chassis ground
is the return cable (+).
5. Remove the screws and flat washers from the terminals.
6. Secure each power cable lug to the terminal with the flat washers and screw (see
Figure 8 on page 16). 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 return (+) terminal.
b. Secure the negative DC source power cable lug to the 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 the screw is 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
15Copyright © 2015, Juniper Networks, Inc.

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.
7. Replace the plastic cover over the terminals on the faceplate.
8. 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.
9. 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.
10. Switch on the external circuit breakers to provide voltage to the DC power source
cable leads. Observe the status LED on the power supply faceplate. If a DC power
supply is correctly installed and is functioning normally, the status LED lights green
steadily. If the status LED indicates that the power supply is not functioning normally,
repeat the cabling procedures.

Safety Warnings
WARNING: See installation instructions before connecting the router. This
is a summary of safety warnings. 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/.
WARNING: The intrabuilding port(s) of the router is suitable for connection
to intrabuilding or unexposed wiring or cabling only. The intrabuilding port(s)
of the router MUST NOT be metallically connected to interfaces that connect
to the OSP or its wiring. These interfaces are designed for use as intrabuilding
interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue
4) and require isolation from the exposed OSP cabling. The addition of primary
protectors is not sufficient protection to connect these interfaces metallically
to OSP wiring.
CAUTION: Before removing or installing components of a router, attach an
ESD strap to an ESD point, and place the other end of the strap around your
bare wrist. Failure to use an ESD strap could result in damage to the router.
CAUTION: Use an external surge protective device (SPD) at the AC input of
the router.
•Only trained and qualified personnel should install or replace the router.
•Perform only the procedures described in this quick start or the ACX4000 Universal
Access Routers Hardware Guide. Other services should be performed by authorized
service personnel only.
•Read the installation instructions before you connect the router to a power source.
