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;

}

}

}
}

xi

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]

xii

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.

System Overview

The PTX10001 is a fixed-configuration router that supports 10-Gbps, 40-Gbps, and 100-Gbps port speeds
in a single 1U stackable platform.

Control operations are performed by the Routing Engine, which runs the Juniper Networks Junos

•

operating system (Junos OS). The Routing Engine handles routing protocols, traffic engineering, policy,
policing, monitoring, and configuration management. Junos OS is installed on the PTX10001 router’s
internal 2 x 50-gigabyte (GB) M.2 SATA solid-state drives (SSDs). The Routing Engine is enhanced by a

1.6-GHz 4 core Intel CPU and 24 GB of SDRAM.

19

Forwarding operations are performed by the Packet Forwarding Engine, which uses Juniper Networks

•

Express-based silicon. The custom ASICs enable the PTX10001 to provide up to 3.6 Tbps of throughput
and 2 Bpps of forwarding capacity.

TIP: For information about features supported on PTX Series routers, see Feature Explorer.

“PTX10001 Packet Transport Router
Description” on page 18

“PTX10001 Cooling System” on
page 31

“PTX10001 Power System” on
page 34

Power supplies—The PTX10001 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
interruption. To provide power redundancy to the system both power supplies must be installed. 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 PTX10001 has five fan modules. If a fan module fails and the remaining fan modules

•

are unable to keep the PTX10001 within the desired temperature thresholds, chassis alarms occur and
the PTX10001 can shut down.

PTX10001 Field-Replaceable Units

Field-replaceable units (FRUs) are components that you can replace at your site.

CAUTION: Replace a failed fan module with a new fan module within 30 seconds of

removal to prevent chassis overheating.

22

Table 5 on page 22 lists the FRUs for the PTX10001 and actions to take before removing them.

Table 5: Required Actions Before Removing a FRU from the PTX10001

Required Actions Before RemovalFRU

Fan Modules

The cooling system in a PTX10001 device consists of fan modules and a single fan in each power supply.
There are five fan modules in the PTX10001. The airflow direction on the PTX10001 is airflow out, air
comes into the device through the vents in the port panel.

The fan modules in the PTX10001 are hot-insertable and hot-removable field-replaceable units (FRUs).
These fan modules are designed for the airflow out direction. The fan modules are installed in the fan
module slots on the management panel of the device next to the power supplies. The PTX10001 has 5
fan modules numbered 0 through 4 from left to right. Each fan module slot has a fan icon next to it.

Figure 8 on page 32 shows the location of the fan modules on the device. Figure 9 on page 32 shows an

example of the fan module.

Airflow Through the Chassis

g050875

Ports FRUs

In the PTX10001 cooling system, cool air enters through the vents in the port panel and hot air exhausts
through the FRU panel. This type of airflow is known as airflow out or port-to-FRU airflow. When the chassis
is installed, it must be positioned so that the FRUs are next to the hot aisle. Figure 10 on page 33 shows
the airflow through the chassis.

Figure 10: Airflow Through the PTX10001 Chassis (Port-to-FRU)

33

NOTE: Under normal operating conditions, the fan modules operate at a moderate speed.

Temperature sensors in the chassis monitor the temperature within the chassis. The system
raises an alarm if a fan module fails or if the ambient temperature inside the chassis rises above
the acceptable range. If the temperature inside the chassis rises above the threshold temperature,
the system shuts down automatically.

PTX10001 Fan Module LEDs

You can check the status of fan modules through the show system alarms command or by looking at the
LEDs next to each fan module.

PTX10001 Environmental Requirements and Specifications

The PTX10001 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 PTX10001 cooling system.

50

Maintain ambient airflow for normal PTX10001 operation. If the airflow is blocked or restricted, or if

•

the intake air is too warm, the chassis might overheat, leading to the PTX10001 temperature monitor
shutting down the router to protect the hardware components.

Table 19 on page 50 provides the required environmental conditions for normal PTX10001 operation.

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.

•

51

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.

•

PTX10001 Chassis Grounding Cable and Lug Specifications

For installations that require a separate grounding conductor to the chassis, the PTX10001 must be
adequately grounded before power is connected to ensure proper operation and to meet safety and
electromagnetic interference (EMI) requirements. To ground a PTX10001, connect a grounding cable to
earth ground and then attach it to the chassis grounding points.

WARNING: The device is a pluggable type A equipment installed in a restricted-access

location. It has a separate protective earthing terminal provided on the chassis in
addition to the grounding pin of the power supply cord. This separate protective
earthing terminal must be permanently connected to earth ground for installations
that require a separate grounding conductor to the chassis.

on page 81. A cable with an incorrectly attached lug can damage the PTX10001.

Before connecting the PTX10001 to earth ground, review the following information:

The grounding lug required is a Panduit LCD10-10A-L or equivalent (not provided). The grounding lug

•

accommodates 14–10 AWG (2–5.3 mm²) stranded wire.

The grounding cable that you provide for a PTX10001 must be the same size or heavier than the input

•

wire of each power supply. Minimum recommendations are 14 AWG (2 mm²) stranded wire, 60° C wire,
or as permitted by local code.

52

PTX10001 Clearance Requirements for Airflow and Hardware Maintenance

When planning the site for a PTX10001 installation, you must allow sufficient clearance around the installed
chassis (see Figure 18 on page 52).

Figure 18: Clearance Requirements for Airflow and Hardware Maintenance for a PTX10001

Follow these guidelines:

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

•

“PTX10001 Cooling System” on page 31 for more information about the airflow through the chassis.

If you are mounting a PTX10001 in a rack with other equipment, ensure that the exhaust from other

•

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

You must leave at least 24 in. (61 cm) both in front of and behind the PTX10001 for service personnel

•

to remove and install hardware components, you must leave adequate space at the front and back of
the PTX10001. 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.

Rack type: four-post

Mounting bracket
hole spacing

Rack size and
strength

Use a four-post rack that provides bracket holes or hole patterns spaced at 1-U (1.75 in. or

4.45 cm) increments and that meets the size and strength requirements to support the weight.

A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment
(document number EIA-310–D) published by the Electronics Components Industry Association
(http://www.ecianow.org/).

The holes in the mounting brackets are spaced at 1 U (1.75 in. or 4.45 cm), so that the
PTX10001 can be mounted in any rack that provides holes spaced at that distance.

Ensure that the rack complies with the standards for a 19-in. rack as defined in Cabinets,

•

Racks, Panels, and Associated Equipment (document number EIA-310–D) published by the
Electronics Components Industry Association (http://www.ecianow.org/).

Use a 600-mm rack as defined in the four-part Equipment Engineering (EE); European

•

telecommunications standard for equipment practice (document numbers ETS 300 119-1
through 119-4) published by the European Telecommunications Standards Institute
(http://www.etsi.org).

The horizontal spacing between the rails in a rack that complies with this standard is usually
wider than the router’s mounting brackets, which measure 19 in. (48.26 cm) from outer
edge to outer edge. Use approved wing devices to narrow the opening between the rails
as required.

Ensure that the rack rails are spaced widely enough to accommodate the PTX10001 chassis’

•

external dimensions. The outer edges of the front-mounting rails extend the width to 19 in.
(48.26 cm).

Space the front and rear rack rails between 24.25 in. (61.5 cm) to 31 in. (78.74 cm)

•

front-to-back.

Ensure that the rack is strong enough to support the weight of the device.

•

Ensure that the spacing of rails and adjacent racks allows for proper clearance around the

•

PTX10001 and rack.

Rack connection to
building structure

Secure the rack to the building structure.

•

If earthquakes are a possibility in your geographical area, secure the rack to the floor.

PTX10001 Cabinet Requirements

You can mount the PTX10001 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 size and clearance

Cabinet airflow requirements

The minimum cabinet size for accommodating a PTX10001 device is 36 in.
(91.4 cm) deep. Large cabinets improve airflow and reduce the chance of
overheating.

When you mount the device 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 device.

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

•

without recirculating into the device. 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.

The PTX10001 fans exhaust hot air through the vents on the fans and

•

power supplies. Install the device in the cabinet in a way that maximizes
the open space on the FRU side of the chassis. This 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 device and cabinet.

Determining Transceiver Support for the PTX10001

The PTX10001 has 20 network ports. Each of the 20 network ports on the port panel support QSFP+ and
QSFP28 transceivers, direct-attach copper (DAC) cables, active optical cables (AOC) , and DAC breakout
cables (DACBO).

You can configure each of the 20 ports as 10-Gigabit Ethernet ports, 40-Gigabit Ethernet ports, or
100-Gigabit Ethernet ports. See “PTX10001 Port Panel” on page 23 for more information about the
network ports.

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 enables you to search by product, displaying all the transceivers supported on that device, or category,
by interface speed or type. The list of supported transceivers for the PTX10001 is located at

https://pathfinder.juniper.net/hct/product/#prd=PTX10001.

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.

Cable and Connector Specifications for MX and PTX Series Devices

IN THIS SECTION

12-Fiber MPO Connectors | 58

58

24-Fiber MPO Connectors | 63

LC Duplex Connectors | 63

The transceivers that are supported on MX Series and PTX Series devices use fiber-optic cables and
connectors. The type of connector and the type of fiber depends on the transceiver type.

You can determine the type of cable and connector required for your specific transceiver by using the

Hardware Compatibility Tool.

CAUTION: To maintain agency approvals, use only a properly constructed, shielded

cable.

NOTE: The terms multifiber push-on (MPO) and multifiber termination push-on (MTP) describe

the same connector type. The rest of this topic uses MPO to mean MPO or MTP.

12-Fiber MPO Connectors

There are two types of cables used with 12-fiber MPO connectors on Juniper Networks devices—patch
cables with MPO connectors on both ends, and breakout cables with an MPO connector on one end and

four LC duplex connectors on the opposite end. Depending on the application, the cables might use
single-mode fiber (SMF) or multimode fiber (MMF). Juniper Networks sells cables that meet the supported
transceiver requirements, but it is not required to purchase cables from Juniper Networks.

Ensure that you order cables with the correct polarity. Vendors refer to these crossover cables as key up
to key up, latch up to latch up, Type B, or Method B. If you are using patch panels between two transceivers,
ensure that the proper polarity is maintained through the cable plant.

Also, ensure that the fiber end in the connector is finished correctly. Physical contact (PC) refers to fiber
that has been polished flat. Angled physical contact (APC) refers to fiber that has been polished at an angle.
Ultra physical contact (UPC) refers to fiber that has been polished flat, to a finer finish. The required fiber
end is listed with the connector type in the Hardware Compatibility Tool.

12-Fiber Ribbon Patch Cables with MPO Connectors

You can use 12-fiber ribbon patch cables with socket MPO connectors to connect two transceivers of the
same type—for example, 40GBASE-SR4-to-40GBASESR4 or 100GBASE-SR4-to-100GBASE-SR4. You can
also connect 4x10GBASE-LR or 4x10GBASE-SR transceivers by using patch cables—for example,
4x10GBASE-LR-to-4x10GBASE-LR or 4x10GBASE-SR-to-4x10GBASE-SR—instead of breaking the signal
out into four separate signals.

12-Fiber Ribbon Breakout Cables with MPO-to-LC Duplex Connectors

You can use 12-ribbon breakout cables with MPO-to-LC duplex connectors to connect a QSFP+ transceiver
to four separate SFP+ transceivers—for example, 4x10GBASE-LR-to-10GBASE-LR or
4x10GBASE-SR-to-10GBASE-SR SFP+ transceivers. The breakout cable is constructed out of a 12-fiber
ribbon fiber-optic cable. The ribbon cable splits from a single cable with a socket MPO connector on one
end, into four cable pairs with four LC duplex connectors on the opposite end.

63

The MPO optical connector for the CFP2-100G-SR10-D3 is defined in Section 5.6 of the CFP2 Hardware
Specification and Section 88.10.3 of IEEE STD 802.3-2012. These specifications include the following

requirements:

Recommended Option A in IEEE STD 802.3-2012.

•

The transceiver receptacle is a plug. A patch cable with a socket connector is required to mate with the

•

module.

Ferrule finish shall be flat polished interface that is compliant with IEC 61754-7.

•

Alignment key is key up.

•

The optical interface must meet the requirement FT-1435-CORE in Generic Requirements for Multi-Fiber
Optical Connectors. The module must pass the wiggle test defined by IEC 62150-3.

LC Duplex Connectors

You can use patch cables with LC duplex connectors to connect two supported transceivers of the same
type—for example, 40GBASE-LR4-to-40GBASE-LR4 or 100GBASE-LR4-to100GBASE-LR4. The patch
cable is one fiber pair with two LC duplex connectors at opposite ends. LC duplex connectors are also
used with 12-fiber ribbon breakout cables, as described in “12-Fiber Ribbon Breakout Cables with

MPO-to-LC Duplex Connectors” on page 60.

Fiber-Optic Cable Signal Loss, Attenuation, and Dispersion

IN THIS SECTION

64

Signal Loss in Multimode and Single-Mode Fiber-Optic Cable | 64

Attenuation and Dispersion in Fiber-Optic Cable | 65

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.

65

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.

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.

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):

66

PB= PT– P

R

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

PB= PT– P

R

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 66 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

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 66 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 66 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.

will be installed on the V+ (return) DC power input terminal.

The cable with very high resistance (indicating an open circuit) to chassis ground is negative (–) and

•

will be installed on the V– (input) DC power input terminal.

CAUTION: You must ensure that power connections maintain the proper polarity.

The power source cables might be labeled (+) and (–) to indicate their polarity. There
is no standard color coding for DC power cables. The color coding used by the
external DC power source at your site determines the color coding for the leads
on the power cables that attach to the DC power input terminals on each power
supply.

3. Ensure that the input circuit breaker is open so that the voltage across the DC power source cable
leads is 0 V and that the cable leads do not become active while you are connecting DC power.

NOTE: The V+ terminals are referred to as +RTN, and V– terminals are referred to as –48 V

in “DC Power Wiring Sequence Warning” on page 190 and “DC Power Electrical Safety

Guidelines” on page 184.

4. Ensure that the power supplies are fully inserted in the chassis.

5. Remove the terminal block cover. The terminal block cover is a piece of clear plastic that snaps into
place over the terminal block (see Figure 28 on page 90).

6. Remove the screws on the terminals using the screwdriver. Save the screws.

WARNING: Ensure that the power cables do not block access to device components

or drape where people can trip on them.

7. Connect each power supply to the power sources. Secure power source cables to the power supplies
by screwing the ring lugs attached to the cables to the appropriate terminals by using the screw from
the terminals (see Figure 28 on page 90 and Figure 29 on page 90. The PTX10001 is designed to
operate with a DC power supply that has a single, non-redundant, feed input. For source redundancy,
two DC power supplies must be installed; connect source (A) to one power supply and connect source
(B) to the second power supply. This configuration provides the commonly deployed A/B feed
redundancy for the system.

The terminal block of the power supply has four terminals labeled V+, V+, V–, and V– for connecting
DC power source cables labeled positive (+) and negative (–). The V+ terminals are shunted internally
together, as are the V- terminals.

89

CAUTION: The connection between each power source and power supply must

include a circuit breaker.

Do not connect two sources to a single power supply because doing so can
potentially cause circulating current in feed wires whenever there is any difference
in the voltage of the two sources.

a. Secure the ring lug of the positive (+) DC power source cable to the V+ terminal on the DC power

supply.

b. Secure the ring lug of the negative (–) DC power source cable to the V– terminal on the DC power

supply.

c. Tighten the screws on the power supply terminals until snug using the screwdriver. Do not

overtighten—apply between 5 in-lb (0.56 Nm) and 6 in-lb (0.68 Nm) of torque to the screws.

CAUTION: The V+ terminals are shunted internally together, as are the V- terminals.

The same polarity terminal can be wired together from the same source to provide
an additional current path in a higher power chassis. Do not connect the terminals
to different sources.
