Documentation and Release Notes

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;

}

} }

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]

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.

ACX2000 Router Description | 18

ACX2100 Router Description | 19

The ACX2000 and ACX2100 Universal Metro Routers are principally designed to provide superior management for rapid provisioning to the access network. The ACX Series routers support rich Gigabit Ethernet and 10-Gigabit Ethernet capabilities for uplink, along with support for legacy interfaces and Gigabit Ethernet interfaces for radio and NodeB connectivity 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 ACX Series router is a single-board router with a built-in Routing Engine and one Packet Forwarding Engine. Because there is no switching fabric, the single Packet Forwarding Engine takes care of both ingress and egress 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 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 allows 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, 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 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 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.

Benefits of the ACX2000 and ACX2100 Routers

Improved operational efficiency with zero-touch deployment (ZTD)—The ACX Series routers support

•

a zero-touch deployment (ZTD) model that significantly reduces the time for any new equipment installation and provisioning, resulting in improved operational efficiency.

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 7 on page 24.

Figure 7: 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. 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 8 on page 25. 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.

TIP: You can find information about the pluggable transceivers supported on your Juniper

Networks device by using the Hardware Compatibility Tool. In addition to transceiver and connector type, the optical and cable characteristics—where applicable—are documented for each transceiver. The Hardware Compatibility Tool allows you to search by product, displaying all the transceivers supported on that device, or category, displaying all the transceivers by interface speed or type. The Hardware Compatibility Tool is located at

https://apps.juniper.net/hct/.

The list of supported transceivers for the ACX2000 is located at

https://apps.juniper.net/hct/product/#prd=ACX2000. The list of supported transceivers for the

ACX2100 is located at https://apps.juniper.net/hct/product/#prd=ACX2100.

ACX2000 and ACX2100 Alarm Contact Port

The ACX2000 and ACX2100 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 ACX2000 and ACX2100 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 11 on page 55 describes the functions of the alarm contacts.

Figure 12 on page 55 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 12: Sample Output Alarm-Reporting Device

Figure 13 on page 56 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 the ACX2000 and the ACX2100 Router

The clocking ports acquire the clock source and synchronize communication over time-division multiplexing (TDM) interfaces in the router. 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 T1/E1 line clocks, Ethernet recovered clocks, IEEE 1588v2 recovered clocks, or xDSL NTU-R timing. Externally available reference clocks are BITS T1/E1 rate clocks, 1 PPS, and 10 MHz. The four SubMiniature B (SMB) connectors and one RJ-48 port 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 router include:

External building-integrated timing system (BITS) timing port

•

10-MHz timing connectors (one input and one output)

•

1.544-MHz/2.048 MHz T1/E1 (RJ-48) ports for timing input or output

•

1 pulse-per-second (PPS) connectors (one input and one output)

•

Time-of-Day (TOD) RS232 port

•

SyncE support on RJ-45/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

Connecting AC Power Cords to the ACX2100 Router | 104

ACX2100 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.

ACX2000 and ACX2100 DC Power Specifications

The power supplies in DC-powered ACX2000 and ACX2100 routers are built in along the front left panel of the chassis with DC power terminals to connect power to the router. The power supplies are labeled PS0 and PS1.

When the ACX2100 router are operating normally and both power supplies are switched on, load sharing between them occurs automatically. When one power supply fails or is turned off, the other power supply immediately assumes the entire electrical load for the system. A single power supply can provide full power for as long as the router is operational.

NOTE: When only one power supply is available on an ACX2100 router, we recommend that

you connect both the power inputs to the same source. That is, connect both the DC power inputs of the ACX2100 router to the only available power supply. Doing so ensures that you get the maximum amount of hold-up time during a power failure.

ACX2000 and ACX2100 routers support a wide range of voltage ranges as shown in Table 21 on page 65.

General Site Guidelines

Efficient device operation requires proper site planning and maintenance and proper layout of the equipment, rack or cabinet (if used), and wiring closet.

To plan and create an acceptable operating environment for your device and prevent environmentally caused equipment failures:

Keep the area around the chassis free from dust and conductive material, such as metal flakes.

•

Follow prescribed airflow guidelines to ensure that the cooling system functions properly and that

•

exhaust from other equipment does not blow into the intake vents of the device.

Follow the prescribed electrostatic discharge (ESD) prevention procedures to prevent damaging the

•

equipment. Static discharge can cause components to fail completely or intermittently over time.

Install the device in a secure area, so that only authorized personnel can access the device.

•

Site Electrical Wiring Guidelines

Table 23 on page 71 describes the factors you must consider while planning the electrical wiring at your

site.

WARNING: You must provide a properly grounded and shielded environment and use

electrical surge-suppression devices.

Table 23: Site Electrical Wiring Guidelines

Site Wiring Factor

Guidelines

Signaling limitations

Radio frequency interference

Electromagnetic compatibility

If your site experiences any of the following problems, consult experts in electrical surge suppression and shielding:

Improperly installed wires cause radio frequency interference (RFI).

•

Damage from lightning strikes occurs when wires exceed recommended distances or pass between

•

buildings.

Electromagnetic pulses (EMPs) caused by lightning damage unshielded conductors and electronic

•

devices.

To reduce or eliminate RFI from your site wiring, do the following:

Use a twisted-pair cable with a good distribution of grounding conductors.

•

If you must exceed the recommended distances, use a high-quality twisted-pair cable with one

•

ground conductor for each data signal when applicable.

If your site is susceptible to problems with electromagnetic compatibility (EMC), particularly from lightning or radio transmitters, seek expert advice.

Some of the problems caused by strong sources of electromagnetic interference (EMI) are:

Destruction of the signal drivers and receivers in the device

•

Electrical hazards as a result of power surges conducted over the lines into the equipment

•

Clearance Requirements for Airflow and Hardware Maintenance on ACX2000 and ACX2100 Routers

When planning the installation site, allow sufficient clearance around the rack (see Figure 15 on page 72):

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 deploying the router in harsh 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.

Ensure that there is a minimum 1 meter/second airflow in any direction.

ACX2000 and ACX2100 Router Environmental Specifications

The router must be installed in a rack or cabinet housed in a dry, clean, well-ventilated, and temperature-controlled environment.

Ensure that these environmental guidelines are followed:

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.

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

heat up to the operating temperature.

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.

Ensure that the cabinet allows the chassis hot exhaust

•

air 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.

Determining Transceiver Support and Specifications

You can find information about the pluggable transceivers supported on your Juniper Networks device by using the Hardware Compatibility Tool. In addition to transceiver and connector type, the optical and cable characteristics—where applicable—are documented for each transceiver. The Hardware Compatibility Tool allows you to search by product, displaying all the transceivers supported on that device, or category, displaying all the transceivers by interface speed or type. The Hardware Compatibility Tool is located at

https://apps.juniper.net/hct/.

Some transceivers support additional monitoring using the operational mode CLI command show interfaces diagnostics optics. Use the Hardware Compatibility Tool to determine if your transceiver supports monitoring. See the Junos OS documentation for your device for a description of the monitoring fields.

CAUTION: If you face a problem running a Juniper Networks device that uses a

third-party optic or cable, the Juniper Networks Technical Assistance Center (JTAC) can help you diagnose the source of the problem. Your JTAC engineer might recommend that you check the third-party optic or cable and potentially replace it with an equivalent Juniper Networks optic or cable that is qualified for the device.

Calculating Power Budget and Power Margin for Fiber-Optic Cables

Use the information in this topic and the specifications for your optical interface to calculate the power budget and power margin for fiber-optic cables.

TIP: You can use the Hardware Compatibility Tool to find information about the pluggable

transceivers supported on your Juniper Networks device.

To calculate the power budget and power margin, perform the following tasks:

How to Calculate Power Budget for Fiber-Optic Cable | 81

How to Calculate Power Margin for Fiber-Optic Cable | 82

How to Calculate Power Budget for Fiber-Optic Cable

To ensure that fiber-optic connections have sufficient power for correct operation, you need to calculate the link's power budget, which is the maximum amount of power it can transmit. When you calculate the power budget, you use a worst-case analysis to provide a margin of error, even though all the parts of an actual system do not operate at the worst-case levels. To calculate the worst-case estimate of power budget (PB), you assume minimum transmitter power (PT) and minimum receiver sensitivity (PR):

PB= PT– P

The following hypothetical power budget equation uses values measured in decibels (dB) and decibels referred to one milliwatt (dBm):

PB= PT– P

PB= –15 dBm – (–28 dBm)

PB= 13 dB

How to Calculate Power Margin for Fiber-Optic Cable

After calculating a link's power budget, you can calculate the power margin (PM), which represents the amount of power available after subtracting attenuation or link loss (LL) from the power budget (PB). A worst-case estimate of PMassumes maximum LL:

PM= PB– LL

PMgreater than zero indicates that the power budget is sufficient to operate the receiver.

Factors that can cause link loss include higher-order mode losses, modal and chromatic dispersion, connectors, splices, and fiber attenuation. Table 28 on page 82 lists an estimated amount of loss for the factors used in the following sample calculations. For information about the actual amount of signal loss caused by equipment and other factors, refer to vendor documentation.

Table 28: Estimated Values for Factors Causing Link Loss

Multimode—None, if product of bandwidth and distance is less than 500 MHz-km

0.5 dBConnector

0.5 dBSplice

Single mode—0.5 dB/km

Multimode—1 dB/km

The following sample calculation for a 2-km-long multimode link with a power budget (PB) of 13 dB uses the estimated values from Table 28 on page 82 to calculate link loss (LL) as the sum of fiber attenuation

(2 km @ 1 dB/km, or 2 dB) and loss for five connectors (0.5 dB per connector, or 2.5 dB) and two splices (0.5 dB per splice, or 1 dB) as well as higher-order mode losses (0.5 dB). The power margin (PM) is calculated

as follows:

PM= PB– LL

PM= 13 dB – 2 km (1 dB/km) – 5 (0.5 dB) – 2 (0.5 dB) – 0.5 dB

PM= 13 dB – 2 dB – 2.5 dB – 1 dB – 0.5 dB

PM= 7 dB

The following sample calculation for an 8-km-long single-mode link with a power budget (PB) of 13 dB uses the estimated values from Table 28 on page 82 to calculate link loss (LL) as the sum of fiber attenuation

(8 km @ 0.5 dB/km, or 4 dB) and loss for seven connectors (0.5 dB per connector, or 3.5 dB). The power margin (PM) is calculated as follows:

PM= PB– LL

PM= 13 dB – 8 km (0.5 dB/km) – 7(0.5 dB)

PM= 13 dB – 4 dB – 3.5 dB

PM= 5.5 dB

In both examples, the calculated power margin is greater than zero, indicating that the link has sufficient power for transmission and does not exceed the maximum receiver input power.

Fiber-Optic Cable Signal Loss, Attenuation, and Dispersion

IN THIS SECTION

Signal Loss in Multimode and Single-Mode Fiber-Optic Cable | 83

Attenuation and Dispersion in Fiber-Optic Cable | 84

Signal Loss in Multimode and Single-Mode Fiber-Optic Cable

Multimode fiber is large enough in diameter to allow rays of light to reflect internally (bounce off the walls of the fiber). Interfaces with multimode optics typically use LEDs as light sources. However, LEDs are not coherent sources. They spray varying wavelengths of light into the multimode fiber, which reflects the light at different angles. Light rays travel in jagged lines through a multimode fiber, causing signal dispersion. When light traveling in the fiber core radiates into the fiber cladding, higher-order mode loss results. Together these factors limit the transmission distance of multimode fiber compared with single-mode fiber.

Single-mode fiber is so small in diameter that rays of light can reflect internally through one layer only. Interfaces with single-mode optics use lasers as light sources. Lasers generate a single wavelength of light, which travels in a straight line through the single-mode fiber. Compared with multimode fiber, single-mode fiber has higher bandwidth and can carry signals for longer distances.

Exceeding the maximum transmission distances can result in significant signal loss, which causes unreliable transmission.

Attenuation and Dispersion in Fiber-Optic Cable

Correct functioning of an optical data link depends on modulated light reaching the receiver with enough power to be demodulated correctly. Attenuation is the reduction in power of the light signal as it is transmitted. Attenuation is caused by passive media components, such as cables, cable splices, and connectors. Although attenuation is significantly lower for optical fiber than for other media, it still occurs in both multimode and single-mode transmission. An efficient optical data link must have enough light available to overcome attenuation.

Dispersion is the spreading of the signal over time. The following two types of dispersion can affect an optical data link:

Chromatic dispersion—Spreading of the signal over time resulting from the different speeds of light rays.

•

Modal dispersion—Spreading of the signal over time resulting from the different propagation modes in

•

the fiber.

For multimode transmission, modal dispersion, rather than chromatic dispersion or attenuation, usually limits the maximum bit rate and link length. For single-mode transmission, modal dispersion is not a factor. However, at higher bit rates and over longer distances, chromatic dispersion rather than modal dispersion limits maximum link length.

An efficient optical data link must have enough light to exceed the minimum power that the receiver requires to operate within its specifications. In addition, the total dispersion must be less than the limits specified for the type of link in Telcordia Technologies document GR-253-CORE (Section 4.3) and International Telecommunications Union (ITU) document G.957.

When chromatic dispersion is at the maximum allowed, its effect can be considered as a power penalty in the power budget. The optical power budget must allow for the sum of component attenuation, power penalties (including those from dispersion), and a safety margin for unexpected losses.

Installing the ACX2000 or ACX2100 Router in the Rack

NOTE: The router can be installed horizontally in a rack or cabinet. For additional installation

options, contact JTAC.

To install the router in the rack (see Figure 20 on page 99):

CAUTION: Before front mounting the router in a rack, have a qualified technician

verify that the rack is strong enough to support the router's weight (about 7 lb (3.2 kg)) and is adequately supported at the installation site.

NOTE: One person must be available to lift the router while another secures it to the rack.

CAUTION: If you are mounting multiple units on a rack, mount the heaviest unit at

the bottom of the rack, and mount the other units from the bottom of the rack to the top in decreasing order of the weight of the units.

1. Ensure that the rack is in its permanent location and is secured to the building. Ensure that the installation site allows adequate clearance for both airflow and maintenance.

2. Position the router in front of the rack or cabinet.

3. Hold onto the bottom of the chassis, and carefully lift it so that the mounting brackets contact the rack rails.

WARNING: To prevent injury, keep your back straight and lift with your legs, not

your back. Avoid twisting your body as you lift. Balance the load evenly and be sure that your footing is solid.

4. Align the mounting brackets with the holes in the rack rails.

5. Install a mounting screw into each of the open mounting holes aligned with the rack, starting from the bottom.

6. Visually inspect the alignment of the router. If the router is installed properly in the rack, all the mounting screws on one side of the rack should be aligned with the mounting screws on the opposite side, and the router should be level.
