Overview of the M7i Router

M7i Router Description on page 3
M7i Router Description
The M7i Multiservice Edge Router is a complete routing system that provides ATM,
channelized, Ethernet, IP services, and SONET/SDH interfaces for large networks and
network applications, such as those supported by Internet service providers (ISPs).
The router accommodates up to four Physical Interface Cards (PICs). In addition to the
PICs, the Fixed Interface Card (FIC) provides two Fast Ethernet ports or one Gigabit
Ethernet port, depending on your configuration. The built-in tunnel interface on the
Compact Forwarding Engine Board (CFEB) and Enhanced Compact Forwarding Engine
Board (CFEB-E) provides tunneling services. The optional Adaptive Services Module
(ASM) on the CFEB and CFEB-E, and the optional MultiServices Module (MSM) on the
CFEB-E allow one or more services to be configured on this interface.
The router architecture cleanly separates control operations from packet forwarding
operations, which helps to eliminate processing and traffic bottlenecks. Control operations
in the router are performed by the Routing Engine, which runs Junos OS to handle routing
protocols, traffic engineering, policy, policing, monitoring, and configuration management.
Application-specific integrated circuits (ASICs), a definitive part of the router design,
enable the router to forward data at the high speeds demanded by current network
media. Forwarding operations in the router are performed by the Packet Forwarding
Engine, which consists of hardware, including ASICs, designed by Juniper Networks. The
Packet Forwarding Engine can forward up to 16 million packets per second (Mpps) for
all packet sizes. The aggregate throughput is 4 gigabits per second (Gbps), full duplex,
for the FPC with 4 PIC slots. The fixed interface card (FIC) has a maximum throughput
of 1 Gbps full duplex. Inserting a combination of PICs with an aggregate higher than the
maximum throughput of the FPC is supported, but constitutes oversubscription of the
FPC.

M7i Component Redundancy
The router can be configured with two load-sharing, fully redundant power supplies to
distribute power to the other components. If one power supply fails, the second power
supply can provide full power to the router's components indefinitely.

M7i Chassis Description
The router chassis is a rigid sheet metal structure that houses the other hardware
components. The chassis is 17.5 in. (44.5 cm) wide and 18 in. (45.7 cm) deep. The chassis
height of 3.5 in. (8.9 cm) enables stacked installation of 21 M7i routers in a single
floor-to-ceiling rack. For more information, see “M7i Router Rack Requirements” on
page 38.
The two mounting brackets (one on each side) extend the chassis width to 19 in.
(48.2 cm).
Figure 1: Front of Chassis
Figure 2: Rear of Chassis
The chassis includes the following electrical safety components:
•
One electrostatic discharge (ESD) points (banana plug receptacles), at the front of
the chassis, as shown in Figure 1 on page 6.
•
Two internally threaded inserts providing grounding points for the router.
WARNING: Before removing or installing components of a functioning router,
attach an ESD strap to an ESD point and place the other end of the strap

around your bare wrist. Failure to use an ESD strap could result in damage
to the router.
The router must be connected to earth ground during normal operation.
For further safety information, see “General Safety Guidelines for Juniper
Networks Devices” on page 129 and “General Safety Warnings for Juniper
Networks Devices” on page 130.
For chassis serial number information , see “Displaying M7i Router Components and Serial
Numbers” on page 191.

M7i Midplane Description
The midplane is a panel located in the center of the chassis, running from side to side
and forming the rear of the PIC card cage (see Figure 3 on page 7). All router components
plug directly into the midplane. The midplane contains an EEPROM that stores the serial
number and revision level of the midplane.
The midplane performs the following functions:
•
Transfer of packets—An incoming data packet crosses the midplane to a CFEB or
CFEB-E. The CFEB or CFEB-E performs switching and forwarding functions and transfers
outgoing packets back across the midplane to the FIC or PICs for transmission to the
network.
•
Power distribution—The midplane distributes power to all router components from
the power supplies attached to it.
•
Signal connectivity—The midplane transports the signals exchanged by system
components for monitoring and control purposes.

Engine Board (CFEB-E) Description
The M7i Multiservice Edge Router houses either a Compact Forwarding Engine Board
(CFEB) or an Enhanced Compact Forwarding Engine Board (CFEB-E), which is located
on the rear of the router above the power supplies, as shown in Figure 2 on page 6. It
provides route lookup, filtering, and switching on incoming data packets, then directs
outbound packets to the appropriate interface for transmission to the network. It can
process 16 million packets per second (Mpps). The CFEB or CFEB-E communicates with
the Routing Engine using a dedicated 100-Mbps link that transfers routing table data
from the Routing Engine to the forwarding table. The link is also used to transfer routing
link-state updates and other packets destined for the router from the CFEB or CFEB-E
to the Routing Engine.
The CFEB or CFEB-E provides the following functions:
•
Route lookups—Performs route lookups using the forwarding table stored in the
synchronous SRAM (SSRAM) on CFEBs or stored in the RLDRAM on CFEB-Es.
•
Management of shared memory —Uniformly allocates incoming data packets
throughout the router's shared memory.
•
Transfer of outgoing data packets—Passes data packets to the destination FIC or PIC
when the data is ready to be transmitted.
•
Transfer of exception and control packets—Passes exception packets to the
microprocessor on the CFEB or CFEB-E, which processes almost all of them. The
remainder are sent to the Routing Engine for further processing. Any errors originating
in the Packet Forwarding Engine and detected by the CFEB or CFEB-E are sent to the
Routing Engine using system log messages.
•
Built-in tunnel interface—Encapsulates arbitrary packets inside a transport protocol,
providing a private, secure path through an otherwise public network.
The built-in tunnel interface on the CFEB or CFEB-E is configured the same way as a
PIC. For information about configuring the built-in tunnel interface, see the Junos OS
Services Interfaces Configuration Guide.
•
Optional Adaptive Services Module (ASM)—Provides one or more services on one PIC.
See “M7i Adaptive Services Module” on page 12 for more information.
The CFEB and CFEB-E are hot-pluggable when you replace a CFEB with a CFEB or a
CFEB-E with a CFEB-E. Upgrading or downgrading a CFEB device requires a system
reboot, as described in “Upgrading and Downgrading the CFEB and CFEB-E” on page 92.
You can remove and replace the CFEB or CFEB-E without powering down the router, but
the routing functions of the system are interrupted when it is removed.

M7i Fixed Interface Card (FIC) Description
The Fixed Interface Card (FIC) is built into the router chassis.
The FIC receives incoming packets from the network and transmits outgoing packets to
the network, providing support for Fast Ethernet ports or Gigabit Internet interfaces,
depending on which version of the FIC is installed in the router.
The FIC also allows you to view alarm status at a glance and to perform some system
control functions, such as taking PICs online and offline.
The FIC is located on the front of the chassis to the left of the Routing Engine and is not
a field-replaceable unit (FRU).
Each FIC consists of the following components:
•
The FIC has either two 100Base-TX Fast Ethernet ports or one Gigabit Ethernet port,
depending on which type of FIC is installed in the router. Table 25 on page 177 describes
the interface connectors. See Figure 9 on page 15 and Figure 10 on page 15.
For more information about Fast Ethernet and Gigabit Ethernet interfaces, see the M7i
Multiservice Edge Router PIC Guide. The networking interface on the FIC is configured
the same way as a PIC. For more information about configuring interfaces see the Junos
OS Network Interfaces Configuration Guide.

M7i PICs Description
PICs physically connect the router to network media. PICs receive incoming packets from
the network and transmit outgoing packets to the network, performing framing and
line-speed signaling for their media type as required. PICs also encapsulate outgoing
packets received from the Compact Forwarding Engine Board (CFEB) or Enhanced CFEB
(CFEB-E) before transmitting them. The controller ASIC on each PIC performs additional
control functions specific to the PIC media type.
16
Copyright © 2012, Juniper Networks, Inc.
Chapter 2: M7i Hardware Components
The router supports various PICs, including ATM, Channelized, Gigabit Ethernet, Services,
and SONET/SDH interfaces. You can install PICs of different media types on the same
router as long as the router supports those PICs.
Blank PICs resemble other PICs but do not provide any physical connection or activity.
When a slot is not occupied by a PIC, you must insert a blank PIC to fill the empty slot
and ensure proper cooling of the system.
Four PIC slots are located in one Flexible PIC Concentrator (FPC), FPC0, which is built in
to the chassis. The PIC slots are numbered from 0 (zero) through 3, right to left. The
number of ports on a PIC depends on the type of PIC.
The M7i router has a maximum throughput of 3.2 Gbps full duplex for the FPC with 4 PIC
slots. Inserting a combination of PICs with an aggregate higher than the maximum
throughput is supported, but constitutes oversubscription of the FPC. The fixed interface
card (FIC) has a maximum throughput of 1 Gbps full duplex.
PICs are hot-removable and hot-insertable.
Most PICs supported on the M7i router have the following components.

router, each FPC is built in (it cannot be removed from the chassis as on other M Series
routers). The networking and services interfaces in the M7i router are grouped onto two
logical FPCs by the router, (see Figure 11 on page 18). PICs are located on FPC 0. On FPC
1 the FIC is located in slot 3 and the built-in tunnel interface is located in slot 2. If the ASM

M7i Routing Engine Description
The Routing Engine runs Junos OS. The software processes that run on the Routing Engine
maintain the routing tables, manage the routing protocols used on the router, control
the router's interfaces, control some chassis components, and provide the interface for
system management and user access to the router.
The Routing Engine is installed into the midplane from the front of the chassis, as shown
in Figure 1 on page 6. When two Routing Engines are installed, both are powered on, but
only one is active (the master); the second Routing Engine is in standby mode and
performs no functions. At boot time, both Routing Engines run an arbitration algorithm
and elect one as master. For a more detailed description of the Routing Engine's role in
router architecture, see “Routing Engine Architecture” on page 31.
The Routing Engine is hot-pluggable. If you have only one Routing Engine, you can remove
and replace the Routing Engine without powering down the router, but the routing
functions of the system are interrupted when it is removed. If the host system is redundant,
the backup Routing Engine is hot-removable and hot-insertable. A backup Routing Engine
can be removed without interrupting routing functions.

(EIA-232) serial cable.
•
AUX/MODEM— Connects the Routing Engine to a laptop, modem, or other auxiliary
device through an RS-232 (EIA-232) serial cable.
•
MGMT—Connects the Routing Engine through an Ethernet connection to a management
LAN (or any other device that plugs into an Ethernet connection) for out-of-band
management. The port uses an autosensing RJ-45 connector to support both 10- and
100-Mbps connections. Two small LEDs on the left edge of the port indicate the
connection in use: the yellow LED lights for a 10-Mbps connection and the green LED
lights for a 100-Mbps connection.
For information about the pinouts for the connectors, see “RJ-45 Connector Pinouts for

M7i Power System Description
The router uses either AC or DC power. You can install one or two load-sharing power
supplies at the bottom rear of the chassis, as shown in Figure 2 on page 6. The power
supplies connect to the midplane, which distributes power to router components
according to their individual voltage requirements.
For full redundancy, two power supplies are required. When the power supplies are
installed and operational, they automatically share the electrical load. If a power supply
stops functioning for any reason, the second power supply instantly begins providing all
the power the router needs for normal functioning. It can provide full power indefinitely.
An enable control signal on the output connector of each power supply ensures that the
supply is fully seated into the router midplane before the supply can be turned on. The
enable pin prevents a user-accessible energy hazard, so there is no interlocking
mechanism. The enable pin disables the voltage at the output connector if the power
supply is not turned off before removal.
Power supplies are hot-removable and hot-insertable, as described in “M7I
Field-Replaceable Units (FRUs)” on page 89. To avoid electrical injury, carefully follow
the instructions in “Replacing an M7i AC Power Supply” on page 111 and “Replacing a DC
Power Supply” on page 116.
Copyright © 2012, Juniper Networks, Inc.
23
M7i Multiservice Edge Router Hardware Guide
NOTE: After powering off a power supply, wait at least 60 seconds before
turning it back on. After powering on a power supply, wait at least 60 seconds
before turning it off.
If the router is completely powered off when you power on the power supply,
the Routing Engine boots as the power supply completes its startup sequence.
If the Routing Engine finishes booting and you need to power off the router
again, first issue the CLI request system halt command. For more information,
see .
After a power supply is powered on, it can take up to 60 seconds for status
indicators—such as the output status LED on the power supply, the command
display output, and messages on the LED display on the craft interface—to
indicate that the power supply is functioning normally. Ignore error indicators
that appear during the first 60 seconds.

M7i Cooling System Overview
The router cooling system consists of a fan tray, located along the left side of the chassis,
that provides side-to-side cooling (see Figure 18 on page 27). It connects directly to the
router midplane. The fan tray is a single unit containing four individually fault-tolerant
fans. If a single fan fails, the remaining fans continue to function indefinitely.
The fan tray is hot-removable and hot-insertable.

M7i Cable Management System
The cable management system consists of racks that attach vertically to each side of
the chassis at the front. Pass PIC cables through the slots in the racks to keep the cables
organized and securely in place, and to avoid bending optical cables beyond the proper
bend radius. The cable management system evenly distributes the weight of a cable, so
that it is not subjected to undue stress at the connector.

System Architecture Overview
The router architecture consists of two major components:
•
Packet Forwarding Engine—Performs Layer 2 and Layer 3 packet switching, route
lookups, and packet forwarding.
•
Routing Engine—Provides Layer 3 routing services and network management.
The Packet Forwarding Engine and the Routing Engine perform independently but
communicate constantly through a 100-Mbps internal link. This arrangement provides
streamlined forwarding and routing control and the ability to run Internet-scale networks
at high speeds. Figure 19 on page 29 illustrates the relationship between the Packet
Forwarding Engine and the Routing Engine.

M7i and M10i Packet Forwarding Engine Architecture
The Packet Forwarding Engine performs Layer 2 and Layer 3 packet switching. The Packet
Forwarding Engine is implemented in application-specific integrated circuits (ASICs). It
uses a centralized route lookup engine and shared memory.
•
Packet Forwarding Engine Components on page 30
•
Data Flow Through the Packet Forwarding Engine on page 30
Packet Forwarding Engine Components
The Packet Forwarding Engine architecture includes the following components:
•
Midplane—Transports packets, notifications, and other signals between the FPCs and
the Packet Forwarding Engine (as well as other system components).
•
Physical Interface Card (PIC)—Physically connects the router to fiber-optic or digital
network media. A controller ASIC in each PIC performs control functions specific to
the PIC media type.
•
Compact Forwarding Engine Board (CFEB) or Enhanced Compact Forwarding Engine
Board (CFEB-E)—Hosts an integrated ASIC, which makes forwarding decisions,
distributes data cells to the shared memory, and directs data packets when they are
ready for transmission.
Data Flow Through the Packet Forwarding Engine
Use of ASICs promotes efficient movement of data packets through the system. Packets
flow through the Packet Forwarding Engine in the following sequence (see Figure 20 on
page 31):
1.
Packets arrive at an incoming networking interface.
2. The networking interface passes the packets to the CFEB or CFEB-E, where the
integrated ASIC processes the packet headers, divides the packets into 64-byte data
cells, and distributes the data cells throughout the memory buffer.
3. The integrated ASIC on the CFEB or CFEB-E performs a route lookup for each packet
and decides how to forward it.
a. If services are configured for the packet, the integrated ASIC reassembles the
packet and passes them to the services interface.
b. The services interface passes the packet to the CFEB or CFEB-E, where the
integrated ASIC processes the packet, divides the packet into 64-byte cells, and
distributes the data cells throughout the memory buffer.
c. The integrated ASIC performs a second route lookup for each packet and decides
how to forward it.
4. The integrated ASIC notifies the outbound networking interface.
30

Chapter 3: System Architecture Overview
5. The integrated ASIC reassembles data cells stored in shared memory into data packets
as they are ready for transmission and passes them to the outbound networking
interface.
6. The outbound networking interface transmits the data packets.

Routing Engine Architecture
The Routing Engine runs the Junos OS, which Juniper Networks has developed and
optimized to handle large numbers of network interfaces and routes. The software
consists of a set of system processes running in protected memory modules on top of
an independent operating system. The Junos kernel supports Junos system processes,
which handle system management processes, routing protocols, and control functions
(see Figure 21 on page 32).
The Routing Engine has a dedicated 100-Mbps internal connection to the Packet
Forwarding Engine.
Copyright © 2012, Juniper Networks, Inc.
31
M7i Multiservice Edge Router Hardware Guide
Figure 21: Routing Engine Architecture
Routing Engine Functions
The Routing Engine handles all routing protocol processes, as well as the software
processes that control the router's interfaces, the chassis components, system
management, and user access to the router. These routing and software processes run
on top of a kernel that interacts with the Packet Forwarding Engine. For more information
about the processes, see the Junos OS System Basics and Services Command Reference.
The Routing Engine includes the following functions and features:
32
•
Processing of routing protocol packets—The Routing Engine handles all packets that
concern routing protocols, freeing the Packet Forwarding Engine to handle only packets
that represent Internet traffic.
•
Software modularity—Because each software process is devoted to a different function
and uses a separate process space, the failure of one process has little or no effect on
the others.
•
In-depth Internet functionality—Each routing protocol is implemented with a complete
set of Internet features and provides full flexibility for advertising, filtering, and modifying
routes. Routing policies are set according to route parameters (for example, prefix,
prefix lengths, and Border Gateway Protocol [BGP] attributes).
•
Scalability—The Junos routing tables have been designed to hold all the routes in
current networks with ample capacity for expansion. Additionally, the Junos OS can
efficiently support large numbers of interfaces and virtual circuits.
•
Management interface—Different levels of system management tools are provided,
including the Junos OS command-line interface (CLI), the Junos XML management
protocol, the craft interface, and SNMP.
•
Storage and change management—Configuration files, system images, and microcode
can be held and maintained in primary and secondary storage systems, permitting
local or remote upgrades.
•
Monitoring efficiency and flexibility—The router supports functions such as alarm
handling and packet counting on every port, without degrading packet-forwarding
performance.
Copyright © 2012, Juniper Networks, Inc.
Chapter 3: System Architecture Overview
The Routing Engine constructs and maintains one or more routing tables (see Figure 22
on page 33). From the routing tables, the Routing Engine derives a table of active routes,
called the forwarding table, which is then copied into the Packet Forwarding Engine. The
design of the ASICs allow the forwarding table in the Packet Forwarding Engine to be
updated without interrupting forwarding performance.

M7i Router Rack Requirements
The router can be installed in many types of racks, including four-post (telco) racks and
open-frame racks. An example of an open-frame rack appears in Figure 23 on
page 39.Table 10 on page 38 summarizes rack requirements and specifications for an
M7i router.
Table 10: Rack Requirements and Specifications for an M7i Router
Rack Requirement
Guidelines
Rack type and mounting bracket hole
spacing
Use a four-post rack or a two-post rack. You can mount the router on any four-post
or two-post rack that provides bracket holes or hole patterns spaced at 1 U
(1.75-in./4.44-cm) increments and that meets the size and strength requirements
specified in this table.
A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated
Equipment (document number EIA-310–D) published by the Electronics Industry
Association (http://www.eia.org).
Rack size and strength
38
•
Ensure that the rack is a 19-in. rack as defined in Cabinets, Racks, Panels, and
Associated Equipment (document number EIA-310–D) published by the Electronics
Industry Association (http://www.eia.org).
•
Ensure that the rack is one of the following standard lengths:
•
23.62 in. (600 mm)
With the use of adaptors, the router can fit into a rack that is 600 mm wide and
600 mm deep 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). Use approved wing devices to narrow
the opening between the rails as required.
•
30.0 in. (762 mm)
•
21.5 in. (800 mm)
•
The rack rails must be spaced widely enough to accommodate the router chassis's
external dimensions: 3.5 in. (8.9 cm) high, 18 in. (45.7 cm) deep, and 17.5 in. (44.5 cm)
wide. The outer edges of the mounting brackets extend the width to 19 in. (48.2 cm).
The spacing of rails and adjacent racks must also allow for the clearances around
the router and rack that are specified in “M7i Router Clearance Requirements for
Airflow and Hardware Maintenance” on page 40.
•
The chassis height of 3.5 in. (8.9 cm) is approximately 2 U. A U is the standard rack
unit defined in Cabinets, Racks, Panels, and Associated Equipment (document number
EIA-310-D) published by the Electronics Industry Association. You can stack 21 M7i
routers in a rack that has at least 42 U (73.5 in. or 1.87 m) of usable vertical space.
•
The rack must be strong enough to support the weight of the fully configured router,
up to 36.5 lb (16.6 kg). If you stack multiple fully configured routers in one rack, it
must be capable of supporting the combined weight of the routers.
•
Ensure that the spacing of rails and adjacent racks allows for the proper clearance
around the switch and rack as specified in “M7i Router Clearance Requirements for
Airflow and Hardware Maintenance” on page 40.

M7i Router Clearance Requirements for Airflow and Hardware Maintenance
When planning the installation site, you need to allow sufficient clearance around the
rack (see Figure 24 on page 40):
•
For the cooling system of side-cooled routers to function properly, the airflow around
the chassis must be unrestricted. Allow at least 6 in. (15.2 cm) of clearance between
side-cooled routers. Allow 2.8 in. (7 cm) between the side of the chassis and any
non-heat-producing surface such as a wall.
•
For service personnel to remove and install hardware components, there must be
adequate space at the front and back of the router. Allow at least 24 in. (61 cm) both
in front of and behind the chassis. NEBS GR-63 recommends at least 30 in. (76.2 cm)
clearance in front of the chassis.
NOTE: We recommend that you do not install the router in a cabinet. If
mounting the router in a cabinet, you must be sure that ventilation is
sufficient to prevent overheating.

M7i Multiservice Edge Router Hardware Guide
Connecting FIC and PIC Cables to the M7i Router
WARNING: Do not look directly into transceivers or into the ends of fiber-optic
cables connected to a transceiver. Fiber-optic transceivers emit laser light
that can damage your eyes.
CAUTION: When handling fiber-optic transceivers and fiber-optic cable,
observe the following precautions:
•
Do not leave a fiber-optic transceiver uncovered except when inserting or
removing cable. The safety cap keeps the port clean and prevents
accidental exposure to laser light.
•
Do not bend fiber-optic cable beyond its minimum bend radius. An arc
smaller than a few inches in diameter can damage the cable and cause
problems that are difficult to diagnose.
•
Do not let fiber-optic cable hang free from the connector. Do not allow
fastened loops of cable to dangle, which stresses the cable at the fastening
point.
Plug network cables into the FIC and the PICs housed in the router.
To connect cables into the cable connector ports in the FIC or a PIC faceplate (see Figure
31 on page 59, which shows a fiber-optic PIC):
1.
Have ready a length of the type of cable used by the FIC or PIC, as specified in “FIC
Specifications for the M7i Router” on page 177 or the M7i Multiservice Edge Router PIC
Guide.
2. If the cable connector port is covered by a rubber safety plug, remove the plug.
3. Insert the cable connector into the cable connector port on the FIC or PIC faceplate.
4. Arrange the cable to prevent it from dislodging or developing stress points. Secure
the cable so that it is not supporting its own weight as it hangs to the floor. Place
excess cable out of the way in a neatly coiled loop. Placing fasteners on the loop helps
to maintain its shape.

on the faceplate of each power supply. Power cables are not supplied with the router.
For information about the required cable type, see .
Copyright © 2012, Juniper Networks, Inc.
61
M7i Multiservice Edge Router Hardware Guide
NOTE: The router must be connected to at least two separate external DC
power sources.
CAUTION: 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 terminal
studs on each power supply. You must ensure that power connections
maintain the proper polarity. The power source cables might be labeled (+)
and (–) to indicate their polarity.
To connect DC power to the router (see Figure 32 on page 63):
1.
Verify that there is no power flowing from either external power source, so that the
voltage across the leads of the power cables is 0 V. Ensure that there is no chance
that the cable leads might become active during the procedure.
2. Verify that a licensed electrician has attached a listed power cable lug to each power
source cable.
3. Loop the power cables through the hook located on the faceplate to the right of the
field-wiring terminals.
4. Depending on the type of power cable lugs used, loosen or remove the screws on the
field-wiring terminals.
5. Insert the power cable lugs into the appropriate field-wiring terminals. Using a number
1 Phillips screwdriver, turn the screw on each field-wiring terminal clockwise to secure
the power cable lug. Apply between 8 lb-in. (.9 Nm) and 9 lb-in. (1.02 Nm) of torque
to each screw.
a. Insert the positive (+) source cable into the return terminal, which is labeled RTN.
b. Insert the negative (–) source cable into the input terminal, which is labeled –48V.
6. Verify that the DC source power cabling and the grounding cabling are correct, that
they are not touching or blocking access to router components, and that they do not
drape where people could trip on them.

Powering On the M7i Router
To power on the router:
1.
Verify that the power supplies are fully inserted in the chassis and the thumbscrews
on their faceplates are tightened.
2. For each power supply on an AC-powered router, verify that the ends of the power
cord are firmly plugged into the appliance inlet on the power supply faceplate and
the external power source receptacle.
For each power supply on a DC-powered router, verify that the source DC power cables
are connected to the appropriate terminal on the power supply faceplate: the positive
(+) source cable to the return terminal (labeled RTN) and the negative (–) source
cable to the input terminal (labeled –48V).
3. Verify that an external management device is connected to one of the Routing Engine
ports on the Routing Engine (AUX/MODEM, CONSOLE, or MGMT). For more information
on connecting management devices, see “Connecting the M7i Router to Management
and Alarm Devices” on page 55.
4. Turn on the power to the external management device.

M7i Multiservice Edge Router Hardware Guide
6. Verify that the OUTPUT OK LED lights steadily.
NOTE: After powering off a power supply, wait at least 60 seconds before
turning it back on. After powering on a power supply, wait at least 60
seconds before turning it off.
If the router is completely powered off when you power on the power
supply, the Routing Engine boots as the power supply completes its startup
sequence. If the Routing Engine finishes booting and you need to power
off the router again, see “Powering Off the M7i Router” on page 64.
After a power supply is powered on, it can take up to 60 seconds for status
indicators—such as the output status LED on the power supply, the
command display output, and messages on the LED display on the craft
interface—to indicate that the power supply is functioning normally. Ignore
error indicators that appear during the first 60 seconds.
7. Press the power switch for the second power supply to the ON ( | ) position and verify
that the OUTPUT OK LED lights steadily. If the LED does not light after 60 seconds,
verify that the power supply is properly inserted into the chassis and repeat the cable
installation procedures described in “Connecting Power to an AC-Powered M7i Router”
on page 61 or “Connecting Power to a DC-Powered Router” on page 61.

Configuring Junos OS
•
Initially Configuring the M7i Router on page 67
Initially Configuring the M7i Router
The router is shipped with the Junos OS preinstalled and ready to be configured when
the router is powered on.
The default boot order for the M7i Multiservice Edge Router is different from other Juniper
Networks routers, because the default configuration of the Routing Engine on the M7i
router does not include an CompactFlash card.
If the Routing Engine does not have an CompactFlash card, two copies of the Junos OS
are preinstalled on the router: one on a PC card that can be inserted into the slot in the
Routing Engine faceplate, and one on a rotating hard disk in the Routing Engine. When
the router boots, it first attempts to access the software image on the PC card. If a PC
card is not inserted into the Routing Engine or the attempt otherwise fails, the router tries
the hard disk.
If the Routing Engine has an CompactFlash card, three copies of the Junos OS are
preinstalled on the router and the boot order is as follows. The router first attempts to
access the image on the PC card. If a PC card is not inserted into the Routing Engine or
the attempt otherwise fails, the router next tries the CompactFlash card, and finally the
hard disk.
You configure the router by issuing Junos OS command-line interface (CLI) commands,
either on a console device attached to the CONSOLE port on the Routing Engine, or over
a telnet connection to a network connected to the MGMT port on the Routing Engine.
Gather the following information before configuring the router:
•
Name the router will use on the network
•
Domain name the router will use
•
IP address and prefix length information for the Ethernet interface
•
IP address of a default router
•
IP address of a DNS server
•
Password for the root user

NOTE: To reinstall the Junos OS, you boot the router from the removable
media. Do not insert the removable media during normal operations. The
router does not operate normally when it is booted from the removable media.
When the router boots from the storage media (removable media, internal CompactFlash
card, or hard disk) it expands its search in the /config directory of the routing platform
for the following files in the following order: juniper.conf (the main configuration file),
rescue.conf (the rescue configuration file), and juniper.conf.1 (the first rollback
configuration file). When the search finds the first configuration file that can be loaded
properly, the file loads and the search ends. If none of the file can be loaded properly,

•
Anchor fiber-optic cable to avoid stress on the connectors. When attaching fiber to an
interface, be sure to secure the fiber so it is not supporting its own weight as it hangs
to the floor. Never let fiber-optic cable hang free from the connector.
•
Avoid bending fiber-optic cable beyond its bend radius. An arc smaller than a few
inches can damage the cable and cause problems that are difficult to diagnose.
•
Frequent plugging and unplugging of fiber-optic cable into and out of optical
instruments, such as ATM or SONET/SDH analyzers, can cause damage to the
instruments that is expensive to repair. Instead, 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 easy and inexpensive to replace.
•
Keep fiber-optic cable connections clean. Small micro-deposits of oil and dust in the
canal of the transceiver or cable connector can cause loss of light, reducing signal
power and possibly causing intermittent problems with the optical connection.
To clean the transceivers, use an appropriate fiber-cleaning device, such as RIFOCS
945/946 Fiber Optic Connector Cleaning System. Follow the directions for the cleaning
kit you use.
After you have cleaned the transceiver on the fiber-optic interface, 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 - Cletop Reel-Type Cleaner – Part#
CLETOP-RL. Follow the directions for the cleaning kit you use.

LEDs on the FIC
The FIC provides status and troubleshooting information at a glance. It is located on the
front of the chassis below the PICs, as shown in Figure 1 on page 6. The LEDs on the FIC
include the following:
•
Alarm—The circular red MAJOR ALARM LED indicates a critical condition that can result
in a system shutdown. The triangular yellow MINOR ALARM LED next to it indicates a
less severe condition that requires monitoring or maintenance. Both alarms can occur
simultaneously. When an alarm LED is lit, issue the show chassis alarms command in
the CLI to determine the cause of the alarm. For more information about the alarm
LEDs, see “M7i Fixed Interface Card (FIC) Description” on page 15. For more information
about the causes of alarms, see “Hardware and Interface Alarm Messages” on page 80.
•
Interface—Each interface on a FIC has a LINK LED that indicates the port is online, and
a ACTIVITY LED that indicates activity on the port.
•
PIC—Each PIC has an LED on the FIC labeled PICS ON/OFF that shows whether the
PIC is online.

Troubleshooting the M7i Power System
When a power supply is functioning correctly, the green LED labeled OUTPUT OK is lit
steadily.
If any other LED states apply, consult the following topics:
•

Blinking or Off on page 85
•
Troubleshooting the M7i Power System When the LED on One M7i Power Supply Is
Off on page 85
Troubleshooting the M7i Power System When the LEDs on All M7i Power Supplies Are Blinking
or Off
Problem
If the LED is off on all power supply faceplates, either someone has switched off power
to the router or the system temperature has exceeded the acceptable maximum. In the
latter case, the Routing Engine shuts down all power supplies. There is no power to the
router, so no LED is lit, including the alarm LEDs on the craft interface.
Solution
Excessive system temperature is almost always caused by excessive environmental
temperature. Correct the environmental temperature before repowering the router.

M7i Multiservice Edge Router Hardware Guide
Solution
Perform the following diagnostic procedure:
1.
Check the red alarm LED on the craft interface:
•
If it is lit, issue the following CLI command for information about the cause of an
alarm condition:
user@host> show chassis alarms
For a list of messages that can appear in the output, see “Hardware and Interface
Alarm Messages” on page 80.
A common cause of power supply shutdown is that the temperature of the power
supply or another router component has exceed the maximum limit.
•
If the red alarm LED is not lit, check that the power switch is in the ON position on
the power supply faceplate.
2. Replace the faulty power supply with a spare. For instructions, see “Replacing an M7i
AC Power Supply” on page 111 and “Replacing a DC Power Supply” on page 116. If the
LED lights correctly on the spare, the original power supply is faulty. Return it to Juniper
Networks for replacement, as described in “Contacting Customer Support” on page 195.
3. If the spare power supply also does not work, connect the router to a different power
source. You might also try replacing the AC power cord (on an AC-powered router)
or DC power cables (on a DC-powered router). For instructions, see Replacing an AC
Power Cord and “Replacing an M7i DC Power Cable” on page 120 (you do not need to
disconnect and reconnect the grounding cable).
4. If you cannot determine the cause of the problem or need additional assistance, see
“Contacting Customer Support” on page 195.

Troubleshooting the M7i Fan Tray
Problem
The fans in the fan tray are not functioning normally.
Solution
The router's single fan tray provides cooling for the router, including the CFEB or CFEB-E,
PICs, power supplies, and Routing Engine.
The cooling system draws in room air through the air intake vent on the left side of the
chassis. After entering the chassis, the air stream separates into separate flows for the
front and rear components. For a graphic depiction of the airflow, see Figure 18 on page 27.
For the cooling system to function properly, the clearance around the chassis must be
sufficient for unobstructed airflow. See “M7i Router Clearance Requirements for Airflow
and Hardware Maintenance” on page 40.
86
Copyright © 2012, Juniper Networks, Inc.
Chapter 14: Troubleshooting M7i Hardware Components
During normal operation, the fans in the fan tray function at less than full speed. The
router constantly monitors the temperatures detected by sensors on the router
components, adjusting the speed of the fans as necessary. If the router temperature
exceeds the acceptable maximum, the router turns off the power supplies.
The following conditions automatically cause the fans to run at full speed and trigger
the indicated alarm:
•
A fan fails (red alarm).
•
The router temperature exceeds the “temperature warm” threshold (yellow alarm).
•
The temperature of the router exceeds the maximum (“temperature hot”) threshold
(red alarm and automatic shutdown of the power supplies).
For more information about cooling-related alarms, see “Hardware and Interface Alarm
Messages” on page 80.
To troubleshoot the fans:
Related
Documentation
•
If the red alarm LED on the craft interface lights, use the show chassis alarms command
to determine the source of the problem. The display reports the number of alarm
conditions and the source of each alarm. For a list of messages, see “Hardware and
Interface Alarm Messages” on page 80.
•
Issue the show chassis alarms command for more information about the source of an
alarm condition.
•
If both power supplies have failed, the system temperature might have exceeded the
threshold, causing the system to shut down. See “Troubleshooting the M7i Power
System When the LEDs on All M7i Power Supplies Are Blinking or Off” on page 85.
•
If the fan tray has failed, it must be replaced for the router to operate normally. For
replacement instructions, see “Replacing the M7i Fan Tray” on page 122. For instructions
about returning a faulty component to Juniper Networks, see “Contacting Customer
Support” on page 195.

M7I Field-Replaceable Units (FRUs)
Field-replaceable units (FRUs) are router components that can be replaced at the
customer site. Replacing most FRUs requires minimal router downtime. The router uses
the following types of FRUs:
•
Hot-removable and hot-insertable FRUs—You can remove and replace these
components without powering down the router or disrupting the routing functions.
•
Hot-pluggable FRUs—You can remove and replace these components without powering
down the router, but the routing functions of the system are interrupted when the
component is removed.
Table 15 on page 89 lists the FRUs for the M7i router.

Removing an M7i PIC
WARNING: Do not look directly into transceivers or into the ends of fiber-optic
cables connected to a transceiver. Fiber-optic transceivers emit laser light
that can damage your eyes.
CAUTION: When handling fiber-optic transceivers and fiber-optic cable,
observe the following precautions:
•
Do not leave a fiber-optic transceiver uncovered except when inserting or
removing cable. The safety cap keeps the port clean and prevents
accidental exposure to laser light.
•
Do not bend fiber-optic cable beyond its minimum bend radius. An arc
smaller than a few inches in diameter can damage the cable and cause
problems that are difficult to diagnose.
•
Do not let fiber-optic cable hang free from the connector. Do not allow
fastened loops of cable to dangle, which stresses the cable at the fastening
point.
To remove a PIC (see Figure 35 on page 94):
1.
Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the
PIC. If the PIC connects to fiber-optic cable, have ready a rubber safety cap for each
transceiver and cable.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect
the strap to one of the ESD points on the chassis. Verify that the router is attached to
a proper earth ground.

3. If the PIC has multiple cable connector ports, label the cable connected to each port
so that you can later reconnect the cables correctly.
4. Press and hold the PIC offline button on the FIC until its failure indicator LED lights,
which usually takes about 5 seconds. The failure LED is usually red; for more
information, see the M7i Multiservice Edge Router PIC Guide.
5. Disconnect the cables from the PIC. If the PIC uses fiber-optic cable, immediately
cover each transceiver and the end of each cable with a rubber safety cap.
6. Arrange the cable to prevent it from dislodging or developing stress points. Secure
the cable so that it is not supporting its own weight as it hangs to the floor. Place
excess cable out of the way in a neatly coiled loop. Placing fasteners on the loop helps
to maintain its shape.
7. Pull the right end of the PIC ejector lever away from the PIC faceplate. This disconnects
the PIC from the midplane.
8. Slide the PIC out of the chassis and place it in the electrostatic bag or on the antistatic
mat.
9. If you are not reinstalling a PIC into the empty PIC slot within a short time, install a
blank PIC panel over the slot to maintain proper airflow in the chassis.

Preventing Electrostatic Discharge Damage to an M7i Router
Many router hardware components are sensitive to damage from static electricity. Some
components can be impaired by voltages as low as 30 V. You can easily generate
potentially damaging static voltages whenever you handle plastic or foam packing
material or if you move components across plastic or carpets. Observe the following
guidelines to minimize the potential for electrostatic discharge (ESD) damage, which
can cause intermittent or complete component failures:
•
Always use an ESD wrist strap or ankle strap, and make sure that it is in direct contact
with your skin.
CAUTION: For safety, periodically check the resistance value of the ESD
strap. The measurement should be in the range of 1 to 10 Mohms.
132
•
When handling any component that is removed from the chassis, make sure the
equipment end of your ESD strap is attached to one of the electrostatic discharge
points on the chassis.
•
Avoid contact between the component and your clothing. ESD voltages emitted from
clothing can still damage components.
•
When removing or installing a component, always place it component-side up on an
antistatic surface, in an antistatic card rack, or in an electrostatic bag (see Figure 59
on page 133). If you are returning a component, place it in an electrostatic bag before
packing it.

General Fire Safety Requirements
In the event of a fire emergency involving network devices, the safety of people is the
primary concern. Establish procedures for protecting people in a fire emergency, provide
safety training, and properly provision fire-control equipment and fire extinguishers.
In addition, establish procedures to protect your equipment in 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 installing and operating your equipment.
Fire Suppression
In the event of an electrical hazard or an electrical fire, 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
(CO ) and Halotron, are most effective for suppressing electrical fires. Type C fire

extinguishers displace the 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,
use this type of inert oxygen displacement extinguisher instead of an extinguisher that
leave residues on equipment.
Do not use multipurpose Type ABC chemical fire extinguishers (dry chemical fire
extinguishers) near Juniper Networks devices. The primary ingredient in these fire
extinguishers is monoammonium phosphate, which is very sticky and difficult to clean.
In addition, in 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.

M7i DC Power Electrical Safety Guidelines
The following electrical safety guidelines apply to a DC-powered router:
•
A DC-powered router is equipped with a DC terminal block that is rated for the power
requirements of a maximally configured router. To supply sufficient power, terminate
the DC input wiring on a facility DC source capable of supplying at least 31 A @ –48 VDC
per input for each power supply.
•
Incorporate an easily accessible disconnect device into the facility wiring. We
recommend that the 48 VDC facility DC source should be equipped with a circuit
breaker rated at 40 A (–48 VDC) minimum, or as required by local code. In the United
States and Canada, the 48 VDC facility should be equipped with a circuit breaker rated
a minimum of 125% of the power provisioned for the input in accordance with the
National Electrical Code in the US and the Canadian Electrical Code in Canada.
•
Run two wires from the circuit breaker box to a source of 48 VDC. Use appropriate
gauge wire to handle up to 50 A.
•
Be sure to connect the ground wire or conduit to a solid office (earth) ground. A closed
loop ring is recommended for terminating the ground conductor at the ground stud.
•
A DC-powered router that is equipped with a DC terminal block is intended only for
installation in a restricted access location. In the United States, a restricted access
area is one in accordance with Articles 110-16, 110-17, and 110-18 of the National Electrical
Code ANSI/NFPA 70.
Copyright © 2012, Juniper Networks, Inc.

M7i Multiservice Edge Router Hardware Guide
NOTE: Primary overcurrent protection is provided by the building circuit
breaker. This breaker should protect against excess currents, short circuits,
and earth faults in accordance with NEC ANSI/NFPA70.

Documentation
•
Ensure that the polarity of the DC input wiring is correct. Under certain conditions,
connections with reversed polarity might trip the primary circuit breaker or damage
the equipment.
•
For personal safety, connect the green and yellow wire to safety (earth) ground at both
the router and the supply side of the DC wiring.
•
The marked input voltage of –48 VDC for a DC-powered router is the nominal voltage
associated with the battery circuit, and any higher voltages are only to be associated
with float voltages for the charging function.
•
Because the router is a positive ground system, you must connect the positive lead to
the terminal labeled RTN, the negative lead to the terminal labeled –48V, and the earth
ground to the chassis grounding points.

DC Power Wiring Terminations Warning
WARNING: When stranded wiring is required, use approved wiring
terminations, such as closed-loop or spade-type with upturned lugs. These
terminations should be the appropriate size for the wires and should clamp
both the insulation and conductor.
Waarschuwing Wanneer geslagen bedrading vereist is, dient u bedrading te
gebruiken die voorzien is van goedgekeurde aansluitingspunten, zoals het
gesloten-lus type of het grijperschop type waarbij de aansluitpunten omhoog
wijzen. Deze aansluitpunten dienen de juiste maat voor de draden te hebben
en dienen zowel de isolatie als de geleider vast te klemmen.
Varoitus Jos säikeellinen johdin on tarpeen, käytä hyväksyttyä johdinliitäntää,
esimerkiksi suljettua silmukkaa tai kourumaista liitäntää, jossa on ylöspäin
käännetyt kiinnityskorvat. Tällaisten liitäntöjen tulee olla kooltaan johtimiin
sopivia ja niiden tulee puristaa yhteen sekä eristeen että johdinosan.
Attention Quand des fils torsadés sont nécessaires, utiliser des douilles
terminales homologuées telles que celles à circuit fermé ou du type à plage
ouverte avec cosses rebroussées. Ces douilles terminales doivent être de la
taille qui convient aux fils et doivent être refermées sur la gaine isolante et
sur le conducteur.
Warnung Wenn Litzenverdrahtung erforderlich ist, sind zugelassene
Verdrahtungsabschlüsse, z.B. Ringoesen oder gabelförmige Kabelschuhe
mit nach oben gerichteten Enden zu verwenden. Diese Abschlüsse sollten
die angemessene Größe für die Drähte haben und sowohl die Isolierung als
auch den Leiter festklemmen.
Avvertenza Quando occorre usare trecce, usare connettori omologati, come
quelli a occhiello o a forcella con linguette rivolte verso l'alto. I connettori

devono avere la misura adatta per il cablaggio e devono serrare sia l'isolante
che il conduttore.
Advarsel Hvis det er nødvendig med flertrådede ledninger, brukes godkjente
ledningsavslutninger, som for eksempel lukket sløyfe eller spadetype med
oppoverbøyde kabelsko. Disse avslutningene skal ha riktig størrelse i forhold
til ledningene, og skal klemme sammen både isolasjonen og lederen.
Aviso Quando forem requeridas montagens de instalação eléctrica de cabo
torcido, use terminações de cabo aprovadas, tais como, terminações de cabo
em circuito fechado e planas com terminais de orelha voltados para cima.
Estas terminações de cabo deverão ser do tamanho apropriado para os
respectivos cabos, e deverão prender simultaneamente o isolamento e o fio
condutor.
¡Atención! Cuando se necesite hilo trenzado, utilizar terminales para cables
homologados, tales como las de tipo "bucle cerrado" o "espada", con las
lengüetas de conexión vueltas hacia arriba. Estos terminales deberán ser del
tamaño apropiado para los cables que se utilicen, y tendrán que sujetar tanto
el aislante como el conductor.
Varning! När flertrådiga ledningar krävs måste godkända ledningskontakter
användas, t.ex. kabelsko av sluten eller öppen typ med uppåtvänd tapp.
Storleken på dessa kontakter måste vara avpassad till ledningarna och måste
kunna hålla både isoleringen och ledaren fastklämda.

You can use the information in Table 19 on page 167 and the M7i Multiservice Edge Router
PIC Guide to calculate power consumption for various hardware configurations, input
current from a different source voltage, and thermal output, as shown in the following
examples. (For an added safety margin, the examples use a generalized value for PICs
of 0.625 A @ 48 V each.)
•
Power consumption for minimum configuration:
Base system + 1 CFEB + 1 RE + 1 PIC =
0.6 A + 1.4 A + 0.7 A + 0.625 A = 3.3 A @ 48 V = 159 W DC
Copyright © 2012, Juniper Networks, Inc.
167
M7i Multiservice Edge Router Hardware Guide
•
Power consumption for maximum configuration:
Base system + 1 CFEB with ASM + 1 RE + 4 PICs =
0.6 A + 1.9 A + 0.7 A + 4(0.625 A) =
0.6 A + 1.9 A + 0.7 A + 2.5 A = 5.7 A @ 48 V = 274 W DC
•
Input current from a DC source other than –48 VDC (based on maximum configuration):
(–54 VDC input) x (input current X) = (–48 VDC) x (input current Y)
54 x X = 48 x 48.2
X = 48 x 48.2/54 = 42.8 A
•
System thermal output for maximally configured AC-powered router:
Watts DC/85% AC PEM efficiency/0.293 = BTU/hr
274/0.85/0.293 = 1100 BTU/hr
•
System thermal output for maximally configured DC-powered router:
Watts DC/0.293 = BTU/hr
274/0.293 = 935 BTU/hr
NOTE: We recommend that you provision at least 13.5 A @ 48 VDC and
use a facility circuit breaker rated for 15 A minimum. Doing so enables you
to operate the router in any configuration without upgrading the power
infrastructure, and allows the router to function at full capacity using
multiple power supplies.

DC Power Cables
To supply power to the router, connect power cables to a separate, dedicated DC power
source for each power supply and attach the cables to the field-wiring terminals on each
power supply. Most sites distribute DC power through a main conduit that leads to
frame-mounted DC power distribution panels, one of which might be located at the top
of the rack that houses the router. A pair of cables (one input and one return) connects
the field-wiring terminals to the power distribution panel.

•
Distance limitations for signaling—Improperly installed wires can emit radio interference.
In addition, the potential for damage from lightning strikes increases if wires exceed
recommended distances or if wires pass between buildings. The electromagnetic pulse
(EMP) caused by lightning can damage unshielded conductors and destroy electronic
devices. If your site has previously experienced such problems, you might want to
consult experts in electrical surge suppression and shielding.
•
Radio frequency interference—You can reduce or eliminate the emission of radio
frequency interference (RFI) from your site wiring by using 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.
•
Electromagnetic compatibility—If your site is susceptible to problems with
electromagnetic compatibility (EMC), particularly from lightning or radio transmitters,
Copyright © 2012, Juniper Networks, Inc.
Appendix D: Power Guidelines, Requirements, and Specifications for the M7i Router
you might want to seek expert advice. Strong sources of electromagnetic interference
(EMI) can destroy the signal drivers and receivers in the router and conduct power
surges over the lines into the equipment, resulting in an electrical hazard. It is particularly
important to provide a properly grounded and shielded environment and to use electrical
surge-suppression devices.
CAUTION: To comply with intrabuilding lightning and surge requirements,
intrabuilding wiring must be shielded, and the shield for the wiring must be
grounded at both ends.

Signal Loss in Multimode and Single-Mode Fiber-Optic Cable for the M7i Router
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. LEDs are not coherent sources, however. 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 (HOL)
results. Together these factors limit the transmission distance of multimode fiber
compared to 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. It is consequently more expensive.
The router uses optical lasers for SONET/SDH PIC single-mode interfaces. These optics
comply with IR-1 of Bellcore GR-253-CORE Issue 2, December 1995 and ANSI TI.105.06.
For information about the maximum transmission distances and wavelength ranges
supported by multimode and single-mode (ATM and SONET/SDH) PIC interfaces, see
the M7i Multiservice Edge Router PIC Guide. Exceeding the maximum transmission distances
can result in significant signal loss, which causes unreliable transmission.

Attenuation and Dispersion in Fiber-Optic Cable on M Series, MX Series, and T Series Routers
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. While 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.
Copyright © 2012, Juniper Networks, Inc.
179
M7i Multiservice Edge Router Hardware Guide
Dispersion is the spreading of the signal in time. The following two types of dispersion
can affect an optical data link:
•
Chromatic dispersion—Spreading of the signal in time resulting from the different
speeds of light rays.
•
Modal dispersion—Spreading of the signal in 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.

Calculating Power Budget for Fiber-Optic Cable for M Series, MX Series, and T Series Routers
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 (P ),
B
you assume minimum transmitter power (P ) and minimum receiver sensitivity (P ):

Factors that can cause link loss include higher-order mode losses (HOL), modal and
chromatic dispersion, connectors, splices, and fiber attenuation. Table 26 on page 181
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.

Fiber attenuation
Single-mode—0.5 dB/km
Multimode—1 dB/km
The following example uses the estimated values in Table 26 on page 181 to calculate
link loss (LL) for a 2-km-long multimode link with a power budget (P ) of 13 dB:
B
•
Fiber attenuation for 2 km @ 1.0 dB/km= 2 dB
•
Loss for five connectors @ 0.5 dB per connector = 5(0.5 dB) = 2.5 dB
•
Loss for two splices @ 0.5 dB per splice =2(0.5 dB) = 1 dB
•
Higher-order mode loss = 0.5 dB
•
Clock recovery module = 1 dB
The power margin (P ) is calculated as follows:
M
P = P – LL
M
B
P = 13 dB – 2 km (1.0 dB/km) – 5 (0.5 dB) – 2 (0.5 dB) – 0.5 dB [HOL] – 1 dB [CRM]
M
P = 13 dB – 2 dB – 2.5 dB – 1 dB – 0.5 dB – 1 dB
M
P = 6 dB
M
The following sample calculation for an 8-km-long single-mode link with a power budget
(P ) of 13 dB uses the estimated values from Table 26 on page 181 to calculate link loss
B
(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 (P ) is calculated as
M
follows:
P = P – LL
M
B
P = 13 dB – 8 km (0.5 dB/km) – 7(0.5 dB)
M
P = 13 dB – 4 dB – 3.5 dB
M
P = 5.5 dB
M
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.

Guidelines for Packing M7i Components for Shipment on page 198
Packing the M7i Router for Shipment
To pack the router for shipment:
1.
Retrieve the shipping crate and packing materials in which the router was originally
shipped. If you do not have these materials, contact your Juniper Networks
representative about approved packaging materials.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect
the strap to one of the ESD points on the chassis. Verify that the router is attached to
a proper earth ground.
3. Power off the router. See “Powering Off the M7i Router” on page 64.
4. Disconnect power from the router: .
•
Unplug the power cord from each power supply. See “Removing an M7i AC Power
Cord” on page 115
NOTE: When multiple AC power supplies are installed in the chassis,
each AC power cord (one for each power supply) must be unplugged
to disconnect power completely from the router.
•
See “Removing an M7I DC Power Cable” on page 120.
NOTE: All DC power cables must be disconnected to disconnect power
completely from the router.
5. Remove the cables that connect to all external devices. For instructions, see “Replacing
the Routing Engine Interface Port Cables” on page 103 and “Removing an M7i PIC” on
page 93.
6. Remove all Field Replaceable Units (FRUs) from the router.
7. Remove the router from the rack:
•
If you are using a mechanical lift, place the lift platform under the router, unscrew
and remove the mounting screws from the rack, and move the router to the shipping
crate.
•
If you are not using a mechanical lift
•
If the router weight is fully supported by a shelf or another router, unscrew and
remove the mounting screws from the rack. Then, move it to the shipping crate.
•
If the router weight is not fully supported by a shelf or another router, one person
should grasp the router while another person unscrews and removes the mounting
screws from the rack. You can then move the router to the shipping crate.

8. Place the router in the shipping crate or onto the pallet. If on a pallet, bolt the router
to the pallet.
9. Cover the router with an ESD bag and place the packing foam on top of and around
the router.
10. Replace the accessory box on top of the packing foam.
11. Securely tape the box closed or place the crate cover over the router.
12. Write the RMA number on the exterior of the box to ensure proper tracking.
