ACX1000 and ACX1100 Routers Quick Start
Descripon
This Quick Start contains informaon you need to install and congure the router quickly. For complete
installaon instrucons, see the ACX1000 and ACX1100 Universal Access Routers Hardware Guide at
hps://www.juniper.net/documentaon/.
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
translaons, see the ACX1000 and ACX1100 Universal Access Routers Hardware Guide
at hps://www.juniper.net/documentaon/.
The ACX Universal Metro Router is principally designed for high-density access and pre-aggregaon and
is environmentally hardened. The router can be used as a cell site router or pre-aggregaon device for
mobile backhaul and a CPE for business or residenal access.
The routers are single-board routers with a built-in Roung 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 ACX Series router is powered by Junos OS, supporng extensive L2 and L3 features, IP/MPLS with
trac engineering, rich network management, fault management, service monitoring and Operaon,
Administraon, and Maintenance (OAM) capabilies, and an open soware development kit (SDK)
system that allows providers to customize and integrate operaons with their own management
systems. For a list of related Junos OS documentaon, see hps://www.juniper.net/documentaon/
soware/junos/.
As part of the mobile backhaul, the ACX Series router at the cell site and the MX Series router at the
aggregaon layer provide comprehensive end-to-end Ethernet, MPLS, and OAM features with the one
Junos OS running on both plaorms.
The compact routers are one rack unit (U; that is, 1.75 in., or 4.45 cm) tall. Several routers can be
stacked in a single oor-to-ceiling rack for increased port density per unit of oor space.
The ACX1000 and ACX1100 routers contain twelve Gigabit Ethernet ports, eight of which are RJ-45
ports. The ports labeled COMBO PORTS provide an addional four RJ-45 ports or four Gigabit Ethernet
SFP ports. You can only use one set of combinaon ports at a me.
The ACX1000 router also contains eight T1/E1 ports.
Figure 1 on page 2 shows the front panel of the ACX1000 router. Figure 2 on page 2 and Figure 3
on page 3 show the front panel of the ACX1100 router.

Step 1: Prepare the Site for Installaon
Prepare your site for installaon 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:
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
mounng brackets extend the width to 19.2 in. (48.7 cm).
• One person must be available to li the router while another secures the router to the rack.
• The rack must be strong enough to support the weight of the fully congured 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.
3

• Ensure that the cabinet allows the chassis hot exhaust air to exit from the cabinet without
recirculang 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 boom of the cabinet is closed and there is
no opening.
• You must install the router into a rack that is secured to the building structure.
• Mount the router at the boom of the rack if it is the only unit in the rack.
• When mounng the router in a parally lled rack, load the rack from the boom to the top, with the
heaviest component at the boom of the rack.
• Install the router only in restricted areas, such as dedicated equipment rooms and equipment closets,
in accordance with Arcles 110-16, 110-17, and 110-18 of the Naonal Electrical Code, ANSI/NFPA
70.

Install the ACX Series Router in the Rack
The router can be installed horizontally in a rack or cabinet.
NOTE: For addional installaon opons, contact JTAC.
One person must be available to li the router while another secures the router to the rack. The chassis
weighs approximately 7 lb (3.2 kg). To install the chassis (see Figure 7 on page 7):
1. Ensure that the rack is in its permanent locaon and is secured to the building. Ensure that the
installaon site allows adequate clearance for both airow and maintenance.
2. Posion the router in front of the rack or cabinet.
3. Have one person grasp both sides of the router, li the router, and posion it in the rack, aligning the
mounng bracket holes with the threaded holes in the rack rails. Make sure the chassis is level.
4. Have the second person install a mounng screw into each of the open mounng holes aligned with
the rack, starng from the boom.

Tools Required to Ground the 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 LCD06-10A 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 connecng a grounding cable to earth ground and then aaching it to the
chassis grounding points. To ground the router:
1. Verify that a licensed electrician has aached the cable lug, which is provided with the router, to the
grounding cable.
2. Aach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an
approved site ESD grounding point. See the instrucons for your site.
3. Ensure that all grounding surfaces are clean and brought to a bright nish before you make grounding
connecons.
4. Connect the grounding cable to a proper earth ground.
5. Detach the ESD grounding strap from the site ESD grounding point.
6. Aach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an ESD
grounding point.
7. Place the grounding cable lug over the grounding points on the front of the chassis (see Figure 8 on
page 9).
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 overghten the screw. (Use a
number 2 Phillips screwdriver.)
CAUTION: Ensure that each grounding cable lug seats ush against the surface of the
grounding points as you are ghtening the screws. Ensure that each screw is properly
8

threaded into the grounding points. Applying installaon torque to the screw when
improperly threaded may result in damage to the terminal.
CAUTION: The maximum torque rang 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 ghten 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.

3. Plug the other end of the cable into the network device.
Connect the ACX Series Router to a Management Console or Auxiliary
Device
1. Turn o the power to the console or auxiliary device.
2. Plug the RJ-45 end of the serial cable (Figure 9 on page 10 shows the connector) into the
CONSOLE/AUX port on the front panel. Figure 1 on page 2, Figure 2 on page 2, and Figure 3 on
page 3 show the port.
3. Plug the female DB-9 end into the device's serial port.
Connect Network Interface Cables to the ACX Series Router
1. Have ready a length of the type of cable used by the network ports. For cable specicaons, see the
ACX1000 and ACX1100 Universal Access Routers Hardware Guide .
NOTE: Shielded cables are required for outside deployment.
2. Remove the rubber safety plug from the cable connector port.
LASER WARNING: Do not look directly into a ber-opc transceiver or into the ends
of ber-opc cables. Fiber-opc transceivers and ber-opc cable connected to a
transceiver emit laser light that can damage your eyes.
CAUTION: Do not leave a ber-opc transceiver uncovered except when inserng 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 supporng its own weight as it hangs to the oor. Place excess cable out of the way in a neatly
coiled loop.
11

CAUTION: Avoid bending ber-opc cable beyond its minimum bend radius. An arc
smaller than a few inches in diameter can damage the cable and cause problems that
are dicult to diagnose.
CAUTION: Do not let ber-opc 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 ACX Series Router
IN THIS SECTION
Connect AC Power to an AC-Powered ACX1100 Router | 12
Connect DC Power to a DC-Powered ACX1000 or ACX1100 Router | 13
Depending on your conguraon, your router uses either AC or DC power supplies. Perform the
appropriate procedures for each power supply in your router.
WARNING: You must ground the router before connecng the power cables.
Connect AC Power to an AC-Powered ACX1100 Router
To connect power to the AC-powered router, you need the following tools:
• AC power cords
1. Locate power cords that have a plug appropriate for your geographical locaon. For more
informaon, see the ACX1000 and ACX1100 Universal Access Routers Hardware Guide .
12

2. Aach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an ESD
grounding point.
3. Insert the appliance coupler end of the power cord into the appliance inlet on the power supply.
4. Insert the power cord plug into an external AC power source receptacle.
NOTE: Each power supply must be connected to a dedicated AC power feed and a dedicated
customer site circuit breaker. We recommend that you use a dedicated customer site circuit
breaker rated for 2 A (100 VAC) minimum or 1 A (240 VAC), or as required by local code.
5. Dress the power cord appropriately. Verify that the power cord does not block the air exhaust and
access to router components, or drape where people could trip on it.
6. Repeat Step 1 through Step 5 for the remaining power supply.
7. Observe the system LED on the router. If an AC power supply is funconing normally, the system
LED lights green steadily.
If the system LED is not lit, the power supply is not funconing normally. Repeat the cabling
procedures.
Connect DC Power to a DC-Powered ACX1000 or ACX1100 Router
To connect power to the DC-powered router, you need the following tools:
• Phillips (+) screwdriver, number 2
• ESD grounding wrist strap
• M3 screws and at washers
• DC power source cables, minimum 14 AWG or as required by local code (not provided)
• Ring lugs, Molex 190700067 or equivalent (not provided)
The DC power supply has four terminals on the front panel, covered by a clear plasc cover.

–60 Operang range: –39 to –72 VDC
1. Aach an electrostac discharge (ESD) grounding strap to your bare wrist, and connect the strap to
one of the ESD points on the chassis. For more informaon about ESD, see the ACX1000 and
ACX1100 Universal Access Routers Hardware Guide .
2. Switch o 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
acve during installaon.
3. Remove the clear plasc cover protecng the terminal on the faceplate.
4. Verify that the DC power cables are correctly labeled before making connecons to the power
supply. In a typical power distribuon scheme where the return is connected to chassis ground at
the baery plant, you can use a mulmeter 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 (indicang an open circuit) to chassis ground is the DC input
cable (–).
b. The cable with very low resistance (indicang a closed circuit) to chassis ground is the return
cable (+).
For +24V:
a. The cable with very low resistance (indicang a closed circuit) to chassis ground is the DC input
cable (–).
b. The cable with very large resistance (indicang an open circuit) to chassis ground is the return
cable (+).
5. Remove the screws and at washers from the terminals.
6. Secure each power cable lug to the terminal with the at washers and screw (see Figure 10 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
overghten the screw. (Use a number 2 Phillips screwdriver.)
a. Secure the posive DC source power cable lug to the return (+) terminal.
b. Secure the negave DC source power cable lug to the input (–) terminal.
14

CAUTION: Ensure that each power cable lug seats ush against the surface of the
terminal block as you are ghtening the screws. Ensure that each screw is properly
threaded into the terminal. Applying installaon torque to the screw when the
screw is improperly threaded may result in damage to the terminal.
CAUTION: The maximum torque rang 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 ghten 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.
7. Replace the clear plasc cover over the terminals on the faceplate.
8. Aach an electrostac discharge (ESD) grounding strap to your bare wrist, and connect the strap to
an approved site ESD grounding point. See the instrucons for your site.
9. Connect each DC power cable to the appropriate external DC power source.
NOTE: For informaon about connecng to external DC power sources, see the instrucons
for your site.
10. 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
funconing normally, the system LED lights green steadily. If the system LED is not lit, the power
supply is not funconing normally. Repeat the installaon and cabling procedures.
