To obtain the most current version of all Juniper Networks®technical documentation, see the product documentation page on the Juniper Networks website at https://www.juniper.net/documentation/.

If the information in the latest release notes differs from the information in the documentation, follow the product Release Notes.

Juniper Networks Books publishes books by Juniper Networks engineers and subject matter experts. These books go beyond the technical documentation to explore the nuances of network architecture, deployment, and administration. The current list can be viewed at https://www.juniper.net/books.

Using the Examples in This Manual

If you want to use the examples in this manual, you can use the load merge or the load merge relative command. These commands cause the software to merge the incoming configuration into the current candidate configuration. The example does not become active until you commit the candidate configuration.

If the example configuration contains the top level of the hierarchy (or multiple hierarchies), the example is a full example. In this case, use the load merge command.

If the example configuration does not start at the top level of the hierarchy, the example is a snippet. In this case, use the load merge relative command. These procedures are described in the following sections.

Merging a Full Example

To merge a full example, follow these steps:

1. From the HTML or PDF version of the manual, copy a configuration example into a text file, save the file with a name, and copy the file to a directory on your routing platform.

For example, copy the following configuration to a file and name the file ex-script.conf. Copy the ex-script.conf file to the /var/tmp directory on your routing platform.

system {

scripts {

commit {

file ex-script.xsl;

}

} } interfaces {

fxp0 {

disable; unit 0 {

family inet {

address 10.0.0.1/24;

}

} }

xii

2. Merge the contents of the file into your routing platform configuration by issuing the load merge configuration mode command:

[edit] user@host# load merge /var/tmp/ex-script.conf load complete

Merging a Snippet

To merge a snippet, follow these steps:

1. From the HTML or PDF version of the manual, copy a configuration snippet into a text file, save the file with a name, and copy the file to a directory on your routing platform.

For example, copy the following snippet to a file and name the file ex-script-snippet.conf. Copy the ex-script-snippet.conf file to the /var/tmp directory on your routing platform.

commit {

file ex-script-snippet.xsl; }

2. Move to the hierarchy level that is relevant for this snippet by issuing the following configuration mode command:

[edit] user@host# edit system scripts [edit system scripts]

xiii

3. Merge the contents of the file into your routing platform configuration by issuing the load merge relative configuration mode command:

[edit system scripts] user@host# load merge relative /var/tmp/ex-script-snippet.conf load complete

For more information about the load command, see CLI Explorer.

ACX500 Universal Metro Router Overview

IN THIS SECTION

Benefits of the ACX500 Router | 21

Juniper Networks ACX500 Universal Metro Routers are principally designed to provide superior management for rapid provisioning to the access network. The ACX500 routers support rich Gigabit Ethernet capabilities for uplink, along with support for Gigabit Ethernet interfaces, in a compact form factor that is environmentally hardened and passively cooled. Seamless, end-to-end MPLS can be used to address legacy and emerging requirements to provide the foundation for a converged network that utilizes the same mobile backhaul infrastructure for business or residential services.

The routers have 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 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 Juniper Networks ACX Series Universal MetroRouters are powered by the Junos operating system (Junos OS), which supports extensive Layer 2 and Layer 3 features, IP and 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 enables providers

to customize and integrate operations with their own management systems. For a list of related Junos OS documentation, see https://www.juniper.net/documentation/software/junos/.

As part of the mobile backhaul, an ACX Series router at the cell site and an 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 ACX500 routers can be installed indoors as well as outdoors:

ACX500 indoor—The compact ACX500 indoor routers are one rack unit (U; that is, 1.75 in. or 4.45 cm)

•

tall. Several routers can be stacked in a single floor-to-ceiling rack for increased port density per unit of floor space. The chassis is a rigid sheet metal structure that houses all the other router components. The chassis of the ACX500 indoor router measures 1.75 in. (4.45 cm) high, 9.4 in. (24 cm) deep, and

17.5 in. (44.5 cm) wide. The outer edges of the mounting brackets extend the width to 19 in. (48 cm) (from the front-mounting brackets to the rear of the chassis). The chassis installs in standard 300-mm deep (or larger) enclosed cabinets, 19-in. equipment racks, or telco open-frame racks.

ACX500 outdoor—The compact ACX500 outdoor routers are environmental hardened, and can be

•

deployed in an outdoor environment, such as on walls and poles. The chassis of the ACX500 indoor router measures 1.75 in. (4.45 cm) high, 9.4 in. (24 cm) deep, and 17.5 in. (44.5 cm) wide. The chassis of the ACX500 outdoor router with the Power over Ethernet (PoE) unit measures 16 in. (40.64 cm) high,

4.7 in. (11.93 cm) deep, and 10 in. (25.4 cm) wide. You need to purchase the pole-mounting kit or the wall-mounting kit from Juniper Networks to mount the router in an outdoor environment.

Benefits of the ACX500 Router

Zero Touch Provisioning (ZTP)—ZTP enables quick deployment of a large number of ACX 500 routers.

•

As the ACX500 supports ZTP, it can be production-ready with little or no manual intervention. As installation and provisioning is faster, overall operational efficiency is improved, and the MPLS deployment in the access layer is simplified.

Integrated high-precision timing (Synchronous Ethernet and Precision Time Protocol)— You can use

•

the ACX500 routers for Synchronous Ethernet and PTP in a hybrid mode for the highest level of frequency (10 ppb) and phase (<500 nS) accuracy required for LTE-A. The ACX500, ACX500-O, and ACX500-O-PoE routers also provide an integrated GPS receiver and can act as a grandmaster (GM) clock for a distributed PTP implementation, used for the aggregation of small cell traffic when the backhaul is transported over the Internet.

Advanced security services— ACX500 routers support IPsec, Media Access Control Security (MACsec),

•

Network Address Translation (NAT), and Trusted Platform Module (TPM) features to protect against potential vulnerabilities to the network as well as subscriber traffic.

Environmentally hardened design—ACX500 routers are temperature hardened and support passive

•

cooling for outdoor deployments in extreme weather conditions. The ACX500-O and ACX500-O-PoE routers are based on environmentally hardened, ruggedized chassis and are IP65-compliant for outdoor deployments (pole mount or stand mount) with no need for an enclosure or cabinet.

High availability and reliability— Junos Continuity on ACX500 eliminates OS upgrades and system

•

reboots when new hardware is added to ACX500 routers. A plug-in package provides the drivers and support files needed to bring the hardware online.

Unified in-service software upgrade (unified ISSU), provides software upgrades between two different Junos OS releases (major or minor) without disrupting network traffic.

Packet Flow on ACX Series Routers

The class-of-service (CoS) architecture for ACX Series routers is in concept similar to that for MX Series routers. The general architecture for ACX Series routers is shown in Figure 4 on page 28.

Figure 4: ACX Series Router Packet Forwarding and Data Flow

Based on the model, ACX Series routers contain a built-in Routing Engine and Packet Forwarding Engine and can contain both T1/E1 and Gigabit Ethernet Ports.

The Packet Forwarding Engine has one or two “pseudo” Flexible PIC Concentrators. Because there is no switching fabric, the single Packet Forwarding Engine takes care of both ingress and egress packet forwarding.

Fixed classification places all packets in the same forwarding class, or the usual multifield (MF) or behavior aggregate (BA) classifications can be used to treat packets differently. BA classification with firewall filters can be used for classification based on IP precedence, DSCP, IEEE, or other bits in the frame or packet header.

However, the ACX Series routers can also employ multiple BA classifiers on the same physical interface.

WRED

The physical interfaces do not have to employ the same type of BA classifier. For example, a single physical interface can use classifiers based on IP precedence as well as IEEE 802.1p. If the CoS bits of interest are on the inner VLAN tag of a dual-tagged VLAN interface, the classifier can examine either the inner or outer bits. (By default, the classification is done based on the outer VLAN tag.)

Eight queues per egress port support scheduling using the weighted deficit round- robin (WDRR) mechanism, a form of round-robin queue servicing. The supported priority levels are strict-high and default (low). The ACX Series router architecture supports both weighted random early detect (WRED) and weighted tail drop (WTD).

All CoS features are supported at line rate.

The packet pipeline through an ACX Series router is shown in Figure 5 on page 29. Note that the rate limiting is done with an integrated architecture along with all other CoS functions. Scheduling and shaping are supported on the output side.

configuration. The MTU applied to family inet gets applied to other families as well, even though it can be configured though CLI and visible in show interface extensive output. The only way to use higher MTU for a family is to manipulate the MTU, apply at interface or family inet levels, and let it calculate for each family automatically. MTU values are not limited to 1500 but can range between 256 to 9216.

ACX500 Indoor Router Description

The ACX500 indoor routers contain a total of 10 ports that support 1-Gbps speed, eight of which are labeled COMBO. At any point of time, you can use a maximum of six ports.

The ports labeled COMBO (combination ports) consist of four Gigabit Ethernet ports that support RJ-45 connectors and four Gigabit Ethernet ports that support small form-factor pluggable (SFP) transceivers. Out of the four RJ-45 ports, three ports support Power over Ethernet (PoE+ and PoE++).

The two ports that are not part of the COMBO ports are Gigabit Ethernet SFP ports.

On the ACX500, the six ports that you can use at any point of time can be two Gigabit Ethernet SFP ports (non-combination) and four ports from the COMBO ports.

NOTE: You can mix and match the four RJ-45 and SFP COMBO ports as long as the port numbers

are unique.

For example, from the COMBO ports, you can use the 0/1/0 SFP port along with the 0/1/1 PoE+ RJ-45 port, but not the 0/1/0 PoE++ RJ-45 port, as the port numbers of the SFP and the RJ-45 ports are same (0/1/0).

Figure 6 on page 52 and Figure 7 on page 52 shows the front views of the AC-powered and the DC-powered

ACX500 indoor routers.

NOTE: The top view and bottom view of an AC-powered ACX500 router are respectively the

same as those of a DC-powered router. The only component that appears different is the power inlet for the two routers.

ACX500 Outdoor Router Description

The ACX500 outdoor routers contain three Gigabit Ethernet ports that support SFP transceivers and three Gigabit Ethernet ports that support RJ-45 connectors. The ACX500 outdoor routers install on a pole or a wall, with the chassis installed in a vertical orientation with the cables pointing downward and the eye bolt for hoisting the router pointing upward.

Alarm Contact Port on ACX500 Routers

The ACX500 router has four external alarm contacts (also known as potential free contacts) for connecting the router to external alarm devices. The port labeled ALARM uses a 15-pin D-type connector. The external alarm contact has 15 pins that accept a single core wire from external alarm devices. A DE15 alarm cable is required to connect the ACX500 router to external alarm devices. Use the gauge wire appropriate for the external device that you are connecting.

Whenever a system condition triggers an alarm, the alarm relay contacts are activated, which in turn activates the external alarm devices. The alarm setting is open or closed.

You can connect and configure two output alarms and four input alarms. Two additional output alarms are reserved and are used to indicate major and minor system alarms. Each output and input alarm has two contacts for connecting the router to external alarm devices. Contact 1 of each alarm can be configured as Normally Open [NO] or Normally Closed [NC] through the CLI. Contact 2 of each alarm functions as a reference [REF] or negative potential terminal for Contact 1 of the corresponding alarm and provides a current path for external alarm devices. Table 7 on page 60 describes the functions of the alarm contacts.

Table 7: Alarm Relay Contact Functions

Current is not flowing through Contact 1 and Contact 2 [REF] when operating normally. When the current flows, the closed alarm is generated.

Current is flowing through Contact 1 and Contact 2 [REF] when operating normally. When the current stops flowing, the open alarm is generated.

Provides the current path for the external alarm-reporting device and functions as a reference or negative potential terminal for Contact 1.

Figure 18 on page 60 shows an example of a wiring diagram for a simple output alarm-reporting device.

In this case the device is a light bulb that illuminates when the device encounters a condition that activates the red alarm LED and relay contacts. The alarm relay contacts can also be used to activate other devices such as bells or buzzers.

Figure 18: Sample Output Alarm-Reporting Device

Figure 19 on page 61 shows an example of a wiring diagram for a simple input alarm-reporting device. In

this case the push button switch is an alarm sensor that triggers an input alarm when a door-open condition occurs.

Clocking Ports on ACX500 Routers

The clocking ports distribute a synchronized clock signal throughout the router by locking onto a clock signal originating from an internal clock source or by connecting to an external clock source.

The reference clock inputs can be Ethernet recovered clocks, IEEE 1588v2 recovered clocks, or xDSL NTU-R timing clocks. Externally available reference clocks are 1 pulse per second (PPS). The one SubMiniature B (SMB, 1 PPS output) connectors on the front panel of the router connect to external clock signal sources. The clocking ports provide the synchronized output clocks from any one of the above reference inputs based on the clock’s priority.

Internal clock sources within the ACX500 routers include:

1 PPS SMB connectors (one output)

•

Time of day (TOD) RJ-45 port (supports RS-422)

•

Synchronous Ethernet support on RJ-45 and SFP ports as timing input or output

•

Packet timing (IEEE 1588v2) includes:

•

Timing input when configured as ordinary clock (OC) or boundary clock (BC)

•

Timing output when configured as BC

Cooling System and Airflow in ACX500 Routers

The ACX500 indoor routers do not contain fans, and are passively cooled through air vents. The air vents in the router are located on both the sides of the router and also on top of the router (see

Figure 20 on page 67). Temperature sensors in the chassis monitor the temperature within the chassis. If

the temperature inside the chassis rises above the threshold, the router shuts down automatically.

Figure 20: Cooling System and Airflow in the ACX500 Indoor Router

The ACX500 outdoor routers do not contain fans, and are passively cooled by internal heat sinks and external cooling fins (see Figure 21 on page 67). The external cooling fins on the body of the ACX500 outdoor router help to dissipate the heat. Unlike the ACX500 indoor routers, the ACX500 outdoor routers do not have air vents.

NOTE: We recommend that you use a dedicated customer-site circuit breaker rated for

20 A (100 VAC) or 16 A (240 VAC), or as required by local code. Doing so enables you to operate the router in any configuration without upgrading the power infrastructure.

ACX500 Router AC Power Cord Specifications

Each AC power supply has a single AC appliance inlet that requires a dedicated AC power feed. Most sites distribute power through a main conduit that leads to frame-mounted power distribution panels, one of which can be located at the top of the rack that houses the router. An AC power cord connects each power supply to the power distribution panel.

You can order detachable AC power cords, each approximately 8 ft (2.5 m) long that supply AC power to the router. The C15 appliance coupler end of the cord, as described by International Electrotechnical Commission (IEC) standard 60320, inserts into the AC appliance inlet coupler. The plug end of the power cord fits into the power source receptacle that is standard for your geographic location.

NOTE: For the ACX500 outdoor routers, use the power cord that is purchased from Juniper

Networks, and which is compatible with the ACX500 outdoor routers. Using a power cord other than that is provided by Juniper Networks with the router can damage the power terminal. The nominal rating of the DC power source are +24 VDC, –48 VDC, and –60 VDC. These power cords are specifically designed to be used only with the specified ACX500 outdoor routers.

The site must be as dust-free as possible, because dust can clog air intake vents and filters, reducing the

•

efficiency of the router cooling system.

Maintain ambient airflow for normal router operation. If the airflow is blocked or restricted, or if the

•

intake air is too warm, the router might overheat, leading to the router temperature monitor shutting down the router to protect the hardware components.

The rack or cabinet must have an adequate supply of cooling air. Allow a minimum of 1 meter/second

•

of airflow over the ACX500 indoor router.

NOTE: Depending on the ambient temperature, it might take up to 5 minutes for the router to

heat up to the operating temperature.

Table 26 on page 86 provides the required environmental conditions for normal operation of the ACX500

indoor and outdoor routers.

and DC-powered models.

Figure 28: Grounding Points on the ACX500 Outdoor Router

NOTE: The location of the grounding points on the ACX500 is the same for both AC-powered

and DC-powered models. The grounding point is located just below the power appliance inlet.

NOTE:

All bare grounding connection points to the ACX500 router must be cleaned and coated with

•

an antioxidant solution before grounding the router.

All surfaces on the ACX500 router that are unplated must be brought to a bright finish and

•

treated with an antioxidant solution before connecting the router.

All nonconductive surfaces on the ACX500 must be removed from all threads and connection

•

points to ensure electrical continuity.

All AC-powered and DC-powered ACX500 routers must be grounded.

•

Grounding Cable Lug Specifications

The grounding cable lug is used to secure the grounding cable to the grounding points on the ACX Series router chassis. The grounding cable lug attaches to the grounding cable (see Figure 29 on page 90) and is

secured to the router by two SAE 10–32 screws of length between 0.25 in. and 0.5 in. The grounding

Rack Requirements for ACX500 Indoor Routers | 94

Cabinet Requirements for ACX500 Indoor Routers

You can mount the indoor router in a cabinet that contains a 19-in. (48.3 cm) rack.

Cabinet requirements consist of:

Cabinet size

•

Clearance requirements

•

Cabinet airflow requirements

•

Table 27 on page 91 provides the cabinet requirements and specifications for the router.

Table 27: Cabinet Requirements and Specifications for the ACX500 Indoor Router

GuidelinesCabinet Requirement

Cabinet size

Cabinet clearance

You can mount the router in a cabinet that contains a

•

19-in. (48.3 cm) rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number

EIA-310–D) published by the Electronics Industry Association (http://www.eia.org).

NOTE: The cabinet must meet the strength

requirements to support the weight of the router.

The minimum cabinet size must be able to

•

accommodate the maximum external dimensions of the router.

The outer edges of the mounting brackets extend the

•

width of the chassis to 19 in. (48.3 cm).

The minimum total clearance inside the cabinet is 30 in.

•

(76.2 cm) between the inside of the front door and the inside of the rear door.

Table 27: Cabinet Requirements and Specifications for the ACX500 Indoor Router (continued)

GuidelinesCabinet Requirement

Cabinet airflow requirements

When you mount the router in a cabinet, ensure that ventilation through the cabinet is sufficient to prevent overheating.

Ensure an adequate cool air supply to dissipate the

•

thermal output of the router or routers.

When deploying the router in harsh environments,

•

allow a 1–rack unit (U) gap above and below the router.

Minimum 1 meter/second airflow in any direction

•

Ensure that the cabinet allows the hot exhaust air from

•

the chassis to exit the cabinet without recirculating into the router. An open cabinet (without a top or doors) that employs hot air exhaust extraction from the top allows the best airflow through the chassis. If the cabinet contains a top or doors, perforations in these elements assist with removing the hot air exhaust.

Install the router in the cabinet in a way that maximizes

•

the open space on the side of the chassis that has the hot air exhaust. This space maximizes the clearance for critical airflow.

Route and dress all cables to minimize the blockage of

•

airflow to and from the chassis.

Ensure that the spacing of rails and adjacent cabinets

•

allows for the proper clearance around the router and cabinet.

A cabinet larger than the minimum required provides

•

better airflow and reduces the chance of overheating.
