The Juniper Networks ACX6160 Universal Metro Router is a standalone opcal transponder that has 12
network ports, of which 8 are client ports, and 4 are line ports. It has removable DC power supplies and
cooling fans. It supports the Open ROADM Mul-Source Agreements (MSA) (Version 2.2.1).
The ACX6160 is a transparent transponder that supports:
• Eight 100-Gigabit Ethernet/OTU4 client interfaces that support QSFP28 LR4 opcs.
NOTE: Only four client interfaces are currently supported.
• Four 100-Gbps coherent dense wavelength division mulplexing (DWDM) line interfaces that
support CFP2-DCO opcs. These interfaces ulize quadrature phase shi keying (QPSK) modulaon
2

with Open ROADM (recongurable opcal add/drop mulplexer)-compliant high-gain forward error
correcon(HG-FEC).
Table 1 on page 3 describes the model.
Table 1: ACX6160 Hardware Model
Model Number Descripon
ACX6160-T-DC This model includes the chassis, ve fan modules, and two DC power supplies.
Benets of the ACX6160
• The ACX6160 provides full Open ROADM compable transponder support for metro packet opcal
transport applicaons in a 1 U plaorm. Open ROADM-compable APIs provide fully compliant
third-party controller support along with HG-FEC-compliant interfaces, enabling true interoperable
transponder funconality.
• The ACX6160 supports a zero touch deployment (ZTD) feature that signicantly reduces the me
required to install and provision new equipment, resulng in lower OpEx, lower TCO, and greater
operaonal eciency. ZTD also reduces the complexity of deploying MPLS in the access layer.
• Disaggregated and open-line system—The ACX6160 opmizes open-line system performance when
combined with disaggregated control design. This enables exible updates with service connuity
and the freedom to deploy best transponder soluons.

Front Panel
The front panel of the ACX6160 contains 12 network ports, comprising eight client ports and four line
ports, LEDs, console and management ports, and system status LEDs. Figure 1 on page 4 shows the
ACX6160 front panel.

ACX6160 Hardware Components
The ACX6160 supports the components in Table 2 on page 5 listed in alphabec order.

Chassis ACX6160-T-CHAS
Fan module ACX6160-FAN-FRU
Power supply JPSU-650W-DC-AFO
ACX6160 Component Redundancy
The following hardware components provide redundancy on an ACX6160:
• Power supplies—The ACX6160 has two power supplies. Each power supply provides power to all
components in the device. The two power supplies provide full power redundancy to the device. If
one power supply fails or is removed, the second power supply balances the electrical load without
interrupon. To provide power redundancy to the system, you must install both power supplies.
Connect power source feed A to one power supply and power source feed B to the second power
supply.
CAUTION: Do not connect feed A and feed B to the same power supply input
terminal.
• Cooling system—The ACX6160 has ve fan modules. If a fan module fails and the remaining fan
modules are unable to keep the ACX6160 within the acceptable temperature thresholds, chassis
alarms occur and the ACX6160 can shut down.
CAUTION: Replace a failed fan module with a new fan module within 4 minutes of
removal to prevent chassis overheang.

ACX6160 Field-Replaceable Units
Field-replaceable units (FRUs) are components that you can replace at your site. The ACX6160 FRUs are
hot-removable and hot-insertable. You can remove and replace them without powering o the
ACX6160 or disrupng the roung funcon.
The ACX6160 allows for two 50 GB serial advanced technology aachment (SATA) solid state drives
(SSD) as a secondary boot drive or for log storage. The SATA SSD is a hot-insertable and hot-removable
eld-replaceable unit (FRU). The SSD cover plate is located on the top of the chassis.
Table 3 on page 6 lists the FRUs for the ACX6160 and acons to take before removing them.
Table 3: Required Acons Before Removing a FRU from the ACX6160
FRU Required Acons Before Removal
Power supplies Remove the cable for the power supply unit.
Fan modules None.
SATA SSD None.
NOTE: If you have a Juniper Care service contract, register any addion, change, or upgrade of
hardware components at hps://www.juniper.net/customers/support/tools/updateinstallbase/ .
Failure to do so can result in signicant delays if you need replacement parts. This note does not
apply if you replace exisng components with the same type of component.

The front panel of the ACX6160 contains network ports, port LEDs, console and management ports, and
system status LEDs. You can manage the ACX6160 by using an open ROADM controller. Figure 3 on
page 7 shows the ACX6160 port panel. There are eight QSFP28 network ports and four line CFP2
ports on the front panel. Only four of the eight QSFP28 ports are currently supported (only the even
ports of QSFP28, ports 0/0, 0/2, 0/4, 0/6 are supported). The system status LEDs that alert you to
minor or major alarms or other issues with the transponder.

QSFP28 Network Ports
The ACX6160 has eight (client) network ports (0/0 through 0/7) that support QSFP28 transceivers.
Currently (only the even ports of QSFP28, ports 0/0, 0/2, 0/4, 0/6 are supported). These transceivers
provide a speed of 100 Gbps, through four 25-Gbps channels. The ports are congured as 100-Gigabit
Ethernet ports by default.
CFP2-DCO Network Ports
The ACX6160 has four line CFP2 network ports (1/0 through 1/3) that support C form-factor pluggable
type 2 transceivers.
ACX6160 Chassis Status LEDs
The ACX6160 has three status LEDs located on the le of the port panel, adjacent to the client port 0/0
(see Figure 4 on page 8). The system status LEDs that alert you to minor or major alarms or other
issues with the router, external clock synchronizaon ports.

ACX6160 Management and Console Port LEDs on the Front Panel
There are two management ports on the ACX6160, both ports are labeled MGMT. The RJ-45
management port is for 10/100/1000BASE-T connecons and is located on the front panel. The other
management port is located on the rear panel.
