ACX710 Description
This Quick Start Guide contains information that you need to install and configure an ACX710 router quickly. For complete
installation instructions, see the ACX710 Universal Metro Router Hardware Guide at https://www.juniper.net/documentation/.
The ACX710 router provides an aggregation solution that is cost-effective and compact, and that supports emerging
deployments such as segment routing and Ethernet VPN (EVPN). The ACX710 includes support for numerous features
such as modern network management using NETCONF and YANG, and precise synchronization that helps address the
increasing demands of high-speed networks.
The ACX710 router is a 1-U compact and fixed-configuration model with high-density 1GbE, 10GbE, and 100GbE ports.
ACX710 routers provide full-duplex throughput of 320 Gbps and 24 Gbit DRAM packet buffer.
We ship these routers with a DC power supply module that has dual power feeds and a fan tray with five high-performance
fans that can effectively cool the chassis.
The port panel of the ACX710 router has the following port configurations:
•Twenty-four 10GbE or 1GbE ports (ports 0through 23) that operate at 10-Gbps speed when you use small form-factor
pluggable plus (SFP+) transceivers or at 1-Gbps speed when you use small form-factor pluggable (SFP) optics. Ports 0

through 15 also support 1000-Mbps speed when you use tri-rate SFP optics. Ports 16 through 23 support 100-Mbps
and 1000-Mbps speeds when you use tri-rate SFP optics.
•Four 100GbE ports (ports 0through 3) that support quad small form-factor pluggable 28 (QSFP28) transceivers. You
can channelize these ports into four 25-Gbps interfaces using breakout cables and channelization configuration. These
ports also support 40-Gbps speed when you use quad small form-factor pluggable plus (QSFP+) optics. You can channelize
these 40-Gbps ports into four 10-Gbps interfaces using breakout cables and channelization configuration.

Rack Requirements for ACX710 Routers
The ACX710 routers are designed to be installed on four-post racks.
Table 1 provides the rack requirements and specifications for ACX710 routers.
Table 1: Rack Requirements for ACX710 Routers
GuidelinesRack Requirement
Use a four-post rack that provides bracket holes or hole patterns spaced at 1-U increments
(1.75 in. or 4.45 cm), and ensure that the rack meets the size and strength requirements to
support the weight of the router.
A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment
(document number EIA-310–D) published by the Electronics Industry Association.
Rack type
Ensure that the holes in the mounting brackets are spaced at 1 U (1.75 in. or 4.45 cm) so that
the router can be mounted in any rack that provides holes spaced at that distance.
Mounting bracket
hole spacing
•Ensure that the rack complies with the standards for a 19-in. rack as defined in Cabinets,
Racks, Panels, and Associated Equipment (document number EIA-310–D) published by the
Electronics Industry Association.
•Use an 800-mm rack as defined in the four-part Equipment Engineering (EE) European
telecommunications standard for equipment practice (document numbers ETS 300 119-1
through 119-4) published by the European Telecommunications Standards Institute
(http://www.etsi.org).
The horizontal spacing between the rails in a rack that complies with this standard is usually
wider than the device's mounting brackets, which measure 19 in. (48.26 cm) from outer edge
to outer edge. Use approved wing devices to narrow the opening between the rails as
required.
•Ensure that the rack rails are spaced widely enough to accommodate the external dimensions
of the router chassis. The outer edges of the front-mounting brackets extend the width to
19 in. (48.26 cm).
•Ensure that for four-post installations, the front and rear rack rails are spaced between
23.6 in. (60 cm) and 36 in. (91.4 cm) front-to-back.
•Ensure that the rack is strong enough to support the weight of the router. A fully configured
ACX710 router weighs about 17.64 lb (8 kg).
•Ensure that the spacing of rails and adjacent racks allows for proper clearance around the
router and rack.

strength
•Secure the rack to the building structure.
•If earthquakes are a possibility in your geographical area, secure the rack to the floor.
•Secure the rack to the ceiling brackets and to the wall or floor brackets for maximum stability.

Router Clearance Requirements
For the cooling system to function properly, the airflow around the chassis must be unrestricted. You must allow sufficient
clearance around the installed chassis for cooling and maintenance.
If you are mounting an ACX710 in a rack with other equipment, ensure that the exhaust from the other equipment does
not blow into the intake vents of the ACX710 chassis.
For service personnel to remove and install hardware components, and to accommodate the interface and power cable
bend radius, there must be adequate space at the front and rear of the router. Allow at least 24 in. (61 cm) of space both
at the front and rear of the router. See Figure 3 for the clearance requirements for ACX710 routers.

Router Cooling and Airflow Requirements
•In ACX710 routers, cool air is pulled through the front of the chassis towards the rear fan tray, and hot air is exhausted
out of the chassis through the rear. Figure 4 shows the airflow through the ACX710 router.
•For the cooling system to function properly, the airflow around the chassis must be unrestricted.
•The rack or cabinet must have an adequate supply of cool air.

Step 3: Connect the Grounding Cable
To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, the router must be
adequately grounded before power is connected.
You need a protective earthing terminal bracket for connecting the chassis to earth ground. This two-holed bracket is
attached on the side of the chassis through the mounting rail, and provides a protective earthing terminal for the router.
The grounding points are in the form of studs that are sized for M6 screws. (You need to provide these screws with
integrated washers as we do not ship them in the accessory kit).
To ground the ACX710 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 other end of the strap to
an approved site ESD grounding point. See the instructions for your site.
3. Ensure that all grounding surfaces are clean and are brought to a bright finish before you make grounding connections.
4. Connect the grounding cable to a proper earth ground.
5. Place the grounding cable lug over the grounding points on the side of the chassis (see Figure 9).

Figure 9: Connect the Grounding Cable to the ACX710 Router
g100882
6. Secure the grounding cable lug with the screws.
7. 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.
Step 4: Connect to Power
The ACX710 router supports a dual feed DC power supply module. Table 2 describes the DC power specifications for
ACX710 routers. For the 2-pole DC circuit breaker, the recommended maximum value is 32 A and the minimum value is
8 A.

Before you begin connecting DC power to the router:
•Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see Prevention
of Electrostatic Discharge Damage).
•Ensure that you have connected the router chassis to earth ground.
8

CAUTION: Before you connect power to the router, a licensed electrician must attach a cable lug
to the grounding and power cables that you supply. A cable with an incorrectly attached lug can
damage the router (for example, by causing a short circuit).
To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation,
you must connect the chassis to earth ground before you connect the chassis to power. For
installations that require a separate grounding conductor to the chassis, use the protective earthing
terminal on the router chassis to connect to the earth ground.
•Ensure that you have the following parts and tools available:
•DC power source cables
•Phillips (+) screwdriver, number 2 (not provided)
•Multimeter (not provided)
To connect DC power to an ACX710 router:
1. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap
to a site ESD point.
2. Power off the DC input appliance inlet on the source power supply.
3. Connect the power cord to the power source outlet.
4. Insert the power cord firmly into the inlet.
