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.

MX150 Router Overview

IN THIS SECTION

Benefits of MX150 Router | 16

MX150 Hardware | 17

System Software | 18

The MX150 Universal Routing Platform is a compact, high-performance edge router that is ideally suited for lower bandwidth service provider applications and distributed service architectures, and for enterprise WAN use-cases. The MX150 supports advanced technologies like telemetry that simplify your operations environment, and maximize network uptime.

The MX150 is 1 rack unit (U) tall. The MX150 can be mounted on a desk or any other level surface, on two posts in a Rack, and on four pots in a rack or Cabinet. The MX150 conserves space and contains costs associated with power and cooling.

Benefits of MX150 Router

System Capacity—MX150 provides 20 Gbps of throughput and supports 1-Gigabit Ethernet and

•

10-Gigabit Ethernet interfaces.

The Programmable Chipset—The chipset implemented in the MX Series routers has a programmable

•

forwarding data structure that allows fast microcode changes in the hardware itself, and a programmable lookup engine that allows inline service processing. the chip’s programmable QoS engine supports coarse and fine-grained queuing to address the requirements of core, edge, and aggregation use cases.

Always-on infrastructure base—MX Series routers ensure network and service availability with a broad

•

set of multilayered physical, logical, and protocol-level resiliency aspects. Junos OS Virtual Chassis technology on MX Series routers supports chassis-level redundancy and enables you to manage two routers as a single element. Multichassis link aggregation group (MC-LAG) implementation supports stateful chassis, card, and port redundancy.

Application-Aware Networking—On MX Series routers you can use deep packet inspection to detect

•

applications, and by using the user-defined policies, you can determine traffic treatment for each application. This feature enables highly customized and differentiated services at scale.

Junos Continuity and Unified In-Service Software Upgrade (Unified ISSU)—With the Junos continuity

g006769

•

plug-in package, you can perform a smooth upgrade when new hardware is installed in your MX Series router.

Unified in-service software upgrade (unified ISSU) enables software upgrades and changes without disrupting network traffic.

Junos Telemetry Interface—Using the Junos telemetry interface data, you can stream component-level

•

data to monitor, analyze, and enhance the performance of the network. Analytics derived from this streaming telemetry can identify current and trending congestion, resource utilization, traffic volume, and buffer occupancy.

Integrated Hardware-Based Timing— You do not need to use external clocks because MX Series routers

•

support highly scalable and reliable hardware-based timing, including Synchronous Ethernet for frequency, and the Precision Time Protocol (PTP) for frequency and phase synchronization. Synchronous Ethernet and PTP can be combined in a hybrid mode to achieve a high level of frequency (10 ppb) and phase (<1.5 uS) accuracy.

MX150 Hardware

The MX150 provide carrier-grade level of a rich set of Layer 2 and Layer 3 features. The MX150 has eight 1-Gigabit Ethernet network ports, two 1-Gigabit Ethernet RJ-45 ports that can be used as either access ports or as uplink ports, two SFP ports, two SFP+ ports, and one management port. The MX150 has a 1 U form factor and is shipped with built-in fans and power supply.

Figure 1: MX150 Port Panel

The MX150 can be used as:

An integrated branch router.

•

A secure router for distributed enterprises.

•

System Software

The MX150 use the Junos OS CLI. You can manage the device by using the Junos CLI, accessible through the console on the device.

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 12 on page 33 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 12: 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

•

Environmental Requirements and Specifications for an MX150

The MX150 must be installed in a rack or cabinet. It must be housed in a dry, clean, well-ventilated, and temperature-controlled environment.

Follow these environmental guidelines:

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

•

efficiency of the device cooling system.

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

•

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

Table 13 on page 34 provides the required environmental conditions for normal operation of the MX150.

Clearance Requirements for Airflow and Hardware Maintenance for an MX150

When planning the site for installing an MX150, you must allow sufficient clearance around the installed chassis (see Figure 10 on page 35).

Figure 10: Clearance Requirements for Airflow and Hardware Maintenance for an MX150

For the cooling system to function properly, the airflow around the chassis must be unrestricted. See

•

“MX150 Cooling System” on page 25 for more information about the airflow through the chassis.

If you are mounting an MX150 in a rack or cabinet with other equipment, ensure that the exhaust from

•

other equipment does not blow into the intake vents of the chassis.

Leave at least 24 in. (61 cm) both in front of and behind the MX150. For service personnel to remove

•

and install hardware components, you must leave adequate space at the front and back of the MX150. NEBS GR-63 recommends that you allow at least 30 in. (76.2 cm) in front of the rack or cabinet and 24 in. (61 cm) behind the rack or cabinet.

Rack-Mounting and Cabinet-Mounting Warnings | 106

Requirements for Mounting an MX150 on a Desktop or Other Level Surface

You can install the MX150 on a desktop or other such level surface, by attaching the four rubber feet (provided) to the bottom of the chassis.

When choosing a location, allow at least 6 in. (15.2 cm) of clearance between the front and back of the chassis and adjacent equipment or walls.

Ensure that the desktop or other level surface on which the device is installed is stable and securely supported.

Cabinet Requirements for an MX150

You can mount the MX150 in an enclosure or cabinet that contains a four-post 19-in. open rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Industry Association.

Cabinet requirements consist of:

Cabinet size and clearance

•

Cabinet airflow requirements

•

Table 14 on page 36 provides the cabinet requirements and specifications for the MX150.

Table 14: Cabinet Requirements for the MX150

GuidelinesCabinet Requirement

Cabinet size and clearance

Cabinet airflow requirements

The minimum cabinet size for accommodating an MX150 is 36 in. (91.4 cm) deep. Large cabinets improve airflow and reduce the chance of overheating.

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

Ensure that the cool air supply you provide through the cabinet adequately

•

dissipates the thermal output of the switch (or switches).

Ensure that the cabinet allows the chassis hot exhaust air to exit the cabinet

•

without recirculating into the switch. 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 switch in the cabinet in a way that maximizes the open space

•

on the side of the chassis that has the hot air exhaust.

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 switch and cabinet.

A cabinet larger than the minimum required provides better airflow and

•

reduces the chance of overheating.

Rack Requirements for an MX150

You can mount the MX150 on two-post racks or four-post racks.

Rack requirements consist of:

Rack type

•

Mounting bracket hole spacing

•

Rack size and strength

•

Rack connection to the building structure

•

Table 15 on page 37 provides the rack requirements and specifications for the MX150.

Understanding MX150 Fiber-Optic Cable Signal Loss, Attenuation, and Dispersion

IN THIS SECTION

Signal Loss in Multimode and Single-Mode Fiber-Optic Cables | 47

Attenuation and Dispersion in Fiber-Optic Cable | 47

To determine the power budget and power margin needed for fiber-optic connections, you need to understand how signal loss, attenuation, and dispersion affect transmission. The MX150 uses various types of network cable, including multimode and single-mode fiber-optic cables.

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

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 light 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 (layers of lower refractive index material in close contact with a core material of higher refractive index), higher-order mode loss occurs. Together, these factors reduce the transmission distance of multimode fiber compared to that of single-mode fiber.

Single-mode fiber is so small in diameter that rays of light 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 to multimode fiber, single-mode fiber has a higher bandwidth and can carry signals for longer distances. It is consequently more expensive.

For information about the maximum transmission distance and supported wavelength range for the types of single-mode and multimode fiber-optic cables that are connected to the MX150, see “Pluggable

Transceivers Supported on MX150” on page 43. Exceeding the maximum transmission distances can result

in significant signal loss, which causes unreliable transmission.

Attenuation and Dispersion in Fiber-Optic Cable

An optical data link functions correctly provided that modulated light reaching the receiver has enough power to be demodulated correctly. Attenuation is the reduction in strength of the light signal during transmission. Passive media components such as cables, cable splices, and connectors cause attenuation. 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 transmit enough light to overcome attenuation.

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

Chromatic dispersion, which is the spreading of the signal over time caused by the different speeds of

•

light rays.

Modal dispersion, which is the spreading of the signal over time caused by 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 limits the 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 within 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.

Calculating the Fiber-Optic Cable Power Budget for an MX150

Calculate the link's power budget when planning fiber-optic cable layout and distances to ensure that fiber-optic connections have sufficient power for correct operation. The power budget is the maximum amount of power the link 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 for fiber-optic cable power budget (PB) for the link:

1. Determine values for the link's minimum transmitter power (PT) and minimum receiver sensitivity (PR). For example, here, (PT) and (PR) are measured in decibels, and decibels are referenced to 1 milliwatt (dBm).

PT= –15 dBm

PR= –28 dBm

NOTE: See the specifications for your transmitter and receiver to find the minimum transmitter

power and minimum receiver sensitivity.

2. Calculate the power budget (PB) by subtracting (PR) from (PT):

–15 dBm – (–28 dBm) = 13 dBm

Calculating the Fiber-Optic Cable Power Margin for an MX150

Calculate the link's power margin when planning fiber-optic cable layout and distances to ensure that fiber-optic connections have sufficient signal power to overcome system losses and still satisfy the minimum input requirements of the receiver for the required performance level. The power margin (PM) is the

amount of power available after attenuation or link loss (LL) has been subtracted from the power budget (PB).

When you calculate the power margin, 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 worst-case levels. A power margin (PM) greater

than zero indicates that the power budget is sufficient to operate the receiver and that it does not exceed the maximum receiver input power. This means the link will work. A (PM) that is zero or negative indicates

insufficient power to operate the receiver. See the specification for your receiver to find the maximum receiver input power.

Before you begin to calculate the power margin:

Calculate the power budget. See “Calculating the Fiber-Optic Cable Power Budget for an MX150” on

•

page 48.

To calculate the worst-case estimate for the power margin (PM) for the link:

1. Determine the maximum value for link loss (LL) by adding estimated values for applicable link-loss factors—for example, use the sample values for various factors as provided in Table 21 on page 49 (here, the link is 2 km long and multimode, and the (PB) is 13 dBm):

This example assumes five connectors. Loss for five connectors: 5 (0.5 dBm) = 2.5 dBm.

This example assumes two splices. Loss for two splices: 2 (0.5 dBm) = 1 dBm.

This example assumes the link is 2 km long. Fiber attenuation for 2 km: 2 km (1 dBm/km) = 2 dBm.

This example assumes the link is 2 km long. Fiber attenuation for 2 km: 2 km (0.5 dBm/km) = 1 dBm.

NOTE: For information about the actual amount of signal loss caused by equipment and

other factors, see your vendor documentation for that equipment.

2. Calculate the (PM) by subtracting (LL) from (PB):

PB– LL = P

13 dBm – 0.5 dBm [HOL] – 5 (0.5 dBm) – 2 (0.5 dBm) – 2 km (1.0 dBm/km) – 1 dB [CRM] = P

13 dBm – 0.5 dBm – 2.5 dBm – 1 dBm – 2 dBm – 1 dBm = P

PM= 6 dBm

The calculated power margin is greater than zero, indicating that the link has sufficient power for transmission. Also, the power margin value does not exceed the maximum receiver input power. Refer to the specifications for your receiver to find the maximum receiver input power.

Removing a Transceiver from an MX150

The transceivers for the MX150 are hot-removable and hot-insertable field-replaceable units (FRUs). You can remove and replace them without powering off the device or disrupting device functions.

Before you begin removing a transceiver from the MX150, ensure that you have taken the necessary precautions for safe handling of lasers (see “Laser and LED Safety Guidelines and Warnings for the MX150”

on page 111).

Ensure that you have the following parts and tools available:

Electrostatic bag or an antistatic mat

•

Rubber safety caps to cover the transceiver and fiber-optic cable connector

•

Dust cover to cover the port

•

To remove a transceiver from the MX150:

1. Place the antistatic bag or antistatic mat on a flat, stable surface.

2. Label the cable connected to the transceiver so that you can reconnect it correctly.

WARNING: Do not look directly into a fiber-optic transceiver or into the ends of

fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to transceivers emit laser light that can damage your eyes.

WARNING: Do not leave a fiber-optic transceiver uncovered except when inserting

or removing a cable. The rubber safety cap keeps the port clean and prevents accidental exposure to laser light.

CAUTION: Do not bend fiber-optic cables beyond their minimum bend radius.

Bending the cables beyond their minimum bend radius can damage the cables and cause problems that are difficult to diagnose.

3. Remove the cable connected to the transceiver (see “Disconnecting a Fiber-Optic Cable from an MX150”

on page 78). Cover the transceiver and the end of each fiber-optic cable connector with a rubber safety

cap immediately after disconnecting the fiber-optic cables.

4. Using your fingers, pull the ejector lever away from the transceiver to unlock the transceiver.

CAUTION: Before removing the transceiver, make sure you open the ejector lever

completely until you hear it click. Doing this prevents damage to the transceiver.

5. Grasp the transceiver ejector lever and gently slide the transceiver approximately 0.5 in. (1.3 cm) straight out of the port (see Figure 20 on page 74).

CAUTION: To avoid electrostatic discharge (ESD) damage to the transceiver, do

not touch the connector pins at the end of the transceiver.

6. Using your fingers, grasp the body of the transceiver and pull it straight out of the port.

7. Place the transceiver in the electrostatic bag or on the antistatic mat placed on a flat, stable surface.

8. Place the dust cover over the empty port.

Figure 20: Removing a Transceiver from an MX150

Installing a Transceiver in an MX150

The transceivers for the MX150 are hot-removable and hot-insertable field-replaceable units (FRUs). You can remove and replace them without powering off the device or disrupting device functions.

Before you begin installing a transceiver in an MX150, ensure that you have taken the necessary precautions for safe handling of lasers (see “Laser and LED Safety Guidelines and Warnings for the MX150” on page 111).

Ensure that you have a rubber safety cap available to cover the transceiver.

To install a transceiver in an MX150 :

CAUTION: To avoid electrostatic discharge (ESD) damage to the transceiver, do not

touch the connector pins at the end of the transceiver.

1. Remove the transceiver from its bag.

2. Check to see whether the transceiver is covered by a rubber safety cap. If it is not, cover the transceiver with a rubber safety cap.

WARNING: Do not leave a fiber-optic transceiver uncovered except when inserting

or removing a cable. The rubber safety cap keeps the port clean and prevents accidental exposure to laser light.

3. If the port in which you want to install the transceiver is covered with a dust cover, remove the dust cover and save it in case you need to cover the port later.

4. Using both hands, carefully place the transceiver in the empty port. The connectors must face the device chassis.

CAUTION: Before you slide the transceiver into the port, ensure that the transceiver

is aligned correctly. Misalignment might cause the pins to bend, making the transceiver unusable. See Figure 21 on page 75 for the correct orientation for your device.

5. Slide the transceiver in gently until it is fully seated. See Figure 21 on page 75 for an example of inserting an SFP or SFP+ transceiver.

6. Remove the rubber safety cap when you are ready to connect the cable to the transceiver.

WARNING: Do not look directly into a fiber-optic transceiver or into the ends of

fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to transceivers emit laser light that can damage your eyes.

Figure 21: Installing a Transceiver in an MX150

Maintaining Fiber-Optic Cables in an MX150

To maintain fiber-optic cables in MX150:

When you unplug a fiber-optic cable from a transceiver, place rubber safety caps over the transceiver

•

and on the end of the cable.

Anchor fiber-optic cable to avoid stress on the connectors. When attaching a fiber-optic cable to a

•

transceiver, be sure to secure the fiber-optic cable so that it is not supporting its own weight as it hangs to the floor. Never let a fiber-optic cable hang free from the connector.

Do not bend fiber-optic cables beyond their minimum bend radius. Bending the cables beyond their

•

minimum bend radius can damage the cables and cause problems that are difficult to diagnose.

Frequent plugging and unplugging of fiber-optic cables in and out of optical instruments can damage

•

the instruments, which are expensive to repair. Attach a short fiber extension to the optical equipment. Any wear and tear due to frequent plugging and unplugging is then absorbed by the short fiber extension, which is easier and less expensive to replace than the instruments.

Keep fiber-optic cable connections clean. Microdeposits of oil and dust in the canal of the transceiver

•

or cable connector can cause loss of light, reduction in signal power, and possibly intermittent problems with the optical connection.

To clean the transceiver canal, use an appropriate fiber-cleaning device such as RIFOCS Fiber Optic Adaptor Cleaning Wands (part number 946). Follow the directions in the cleaning kit you use.

After cleaning the transceiver, make sure that the connector tip of the fiber-optic cable is clean. Use only an approved alcohol-free fiber-optic cable cleaning kit such as the Cletop-S®Fiber Cleaner. Follow

the directions in the cleaning kit you use.

Connecting a Fiber-Optic Cable to an MX150

You can connect fiber-optic cables to the field-replaceable unit (FRU) optical transceivers installed in MX150 routers.

Before you connect a fiber-optic cable to an optical transceiver installed in an MX150, ensure that you have taken the necessary precautions for safe handling of lasers (see “Laser and LED Safety Guidelines

and Warnings for the MX150” on page 111).

To connect a fiber-optic cable to an optical transceiver installed in an MX150:

WARNING: Do not look directly into a fiber-optic transceiver or into the ends of

fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to transceivers emit laser light that can damage your eyes.

WARNING: Do not stare into the laser beam or view it directly with optical instruments

even if the interface has been disabled.

1. If the fiber-optic cable connector is covered by a rubber safety cap, remove the cap. Save the cap.

2. If the optical transceiver is covered by a rubber safety cap, remove the cap. Save the cap.

3. Insert the cable connector into the optical transceiver (see Figure 22 on page 78).

4. Secure the cables so that they are not supporting their own weight. Place excess cable out of the way in a neatly coiled loop. Placing fasteners on a loop helps cables maintain their shape.

CAUTION: Do not bend fiber-optic cables beyond their minimum bend radius.

Bending the cables beyond their minimum bend radius can damage the cables and cause problems that are difficult to diagnose.

CAUTION: Do not let fiber-optic cables hang free from the connector. Do not

allow fastened loops of cables to dangle, which stresses the cables at the fastening point.

Figure 22: Inserting a Fiber-Optic Cable into a Transceiver

Disconnecting a Fiber-Optic Cable from an MX150

Before you disconnect a fiber-optic cable from an optical transceiver installed in an MX150, ensure that you have taken the necessary precautions for safe handling of lasers (see “Laser and LED Safety Guidelines

and Warnings for the MX150” on page 111).

Ensure that you have the following parts and tools available:

Rubber safety cap to cover the transceiver

•

Rubber safety cap to cover the fiber-optic cable connector

•

To disconnect a fiber-optic cable from an optical transceiver installed in the MX150:

1. (Recommended) Disable the port in which the transceiver is installed by including the disable statement at the [edit interfaces] hierarchy level for the specific interface.

WARNING: Do not look directly into a fiber-optic transceiver or into the ends of

fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to transceivers emit laser light that can damage your eyes.

WARNING: Do not stare into the laser beam or view it directly with optical

instruments even if the interface has been disabled.

2. Carefully unplug the fiber-optic cable connector from the transceiver.

3. Cover the transceiver with a rubber safety cap.

WARNING: Do not leave a fiber-optic transceiver uncovered except when inserting

or removing a cable. The rubber safety cap keeps the port clean and prevents accidental exposure to laser light.

4. Cover the fiber-optic cable connector with the rubber safety cap.

Fire Safety Requirements

In the event of a fire emergency, the safety of people is the primary concern. You should establish procedures for protecting people in the event of a fire emergency, provide safety training, and properly provision fire-control equipment and fire extinguishers.

In addition, you should establish procedures to protect your equipment in the event of a fire emergency. Juniper Networks products should be installed in an environment suitable for electronic equipment. We recommend that fire suppression equipment be available in the event of a fire in the vicinity of the equipment and that all local fire, safety, and electrical codes and ordinances be observed when you install and operate your equipment.

Fire Suppression

In the event of an electrical hazard or an electrical fire, you should first turn power off to the equipment at the source. Then use a Type C fire extinguisher, which uses noncorrosive fire retardants, to extinguish the fire.

Fire Suppression Equipment

Type C fire extinguishers, which use noncorrosive fire retardants such as carbon dioxide and Halotron™, are most effective for suppressing electrical fires. Type C fire extinguishers displace oxygen from the point of combustion to eliminate the fire. For extinguishing fire on or around equipment that draws air from the environment for cooling, you should use this type of inert oxygen displacement extinguisher instead of an extinguisher that leaves residues on equipment.

Do not use multipurpose Type ABC chemical fire extinguishers (dry chemical fire extinguishers). The primary ingredient in these fire extinguishers is monoammonium phosphate, which is very sticky and difficult to clean. In addition, in the presence of minute amounts of moisture, monoammonium phosphate can become highly corrosive and corrodes most metals.

Any equipment in a room in which a chemical fire extinguisher has been discharged is subject to premature failure and unreliable operation. The equipment is considered to be irreparably damaged.

NOTE: To keep warranties effective, do not use a dry chemical fire extinguisher to control a fire

at or near a Juniper Networks device. If a dry chemical fire extinguisher is used, the unit is no longer eligible for coverage under a service agreement.

We recommend that you dispose of any irreparably damaged equipment in an environmentally responsible manner.
