M10i Router Description

The M10i Multiservice Edge Router provides high-speed interfaces for medium and large networksand networkapplications, such as those supported by Internetservice providers (ISPs). Application-specific integrated circuits (ASICs), a definitive part of the router design, enable the router toforwarddata at the high speeds demanded by current network media.

The M10i router supports up to eight Physical Interface Cards (PICs). The router height of 34.80 in. (88.4 cm) enables stacked installation of five M10i routers in a single floor-to-ceiling rack, for increased port density per unit of floor space.

The router’s maximum aggregate throughput is 12.8 gigabits per second (Gbps) simplex or 6.4 Gbps full duplex. Inserting a combination of PICs with an aggregate higher than the maximum throughput per FPC is supported, but constitutes oversubscription of the FPC.

The router architecture cleanly separates control operations from packet forwarding operations,which helps to eliminateprocessing and trafficbottlenecks.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. Forwarding operations in the router are performed by the Packet Forwarding Engine, which consists of hardware, including ASICs, designed by Juniper Networks.

M10i System Redundancy

You can configure the router for system redundancy by using three AC or four DC load-sharing, fully-redundant power suppliesto distribute powerto theother components.

AC System Redundancy

AC system redundancy requiresthree independentAC power outlets.If one power supply fails, the other two power supplies provide full power to the router's components indefinitely.

You can set up increased AC system redundancy by using four AC power supplies. In this case, two power supplies are powered from two AC outlets, and the other two power supplies use twoAC outlets froma UPS battery-backed power source. Thislets the router run during AC power outages for the amount of time that the UPS allows.

DC System Redundancy

DC system redundancy requires two power sources from feed A and two power sources from feed B. If one feed fails or is shut down for service, the other feed powers two DC power supplies and can provide full power to the router's components indefinitely.

M10i Midplane Description

The midplane is a panel located in the center of the chassis, running from side to side and formingthe rear of the PIC card cage(see Figure 3 on page7). 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—After being processed by a PIC, an incoming data packet crosses the midplane to the CFEB or the CFEB-E. The CFEB or CFEB-E performs switching and forwarding functions and transfers outgoing packets back across the midplane to the PICs for transmission to the network.

•

Power distribution—The midplane distributes power to all router components from the power supplies attached to it. It also provides hot-plug protection for the PIC and HCM slots.

•

Signal connectivity—The midplane transports the signals exchanged by system components for monitoring and control purposes.

M10i Flexible PIC Concentrators (FPCs) Description

Flexible PIC Concentrators (FPCs) house the PICs that connect the router to network media (for information about PICs, see “M10i PICs Description” on page 8). On the M10i router, each FPC is built in (it cannot be removed from the chassis as on other M Series platforms) and corresponds to a horizontal row of PIC slots. The two FPCs on the M10i router are numbered 0 and 1, top to bottom. Each FPC accommodates up to four PICs.

Documentation

• M10i Midplane Description on page 7

• M10i Chassis Description on page 5

M10i PICs Description

PICs provide the physical connection to various network media types. 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.

The router supportsvarious PICs,including ATM, Channelized, GigabitEthernet, IPServices, and SONET/SDH interfaces. You can install PICs of different media types on the same router as long as the router supports those PICs.

PICs are inserted into a slot in Flexible PIC Concentrators (FPCs), FPC0 and FPC1, which are built in to the chassis. Up to eight PICs install into an M10i router, as shown in Figure 4 on page 9. Four PIC slots are located in each Flexible PIC Concentrator (FPC). The PIC slots on the upper FPC are numbered from 0/0 (zero/zero) through 0/3, right to left. The PIC slots in the lower FPC are numbered from 1/0 (one/zero) through 1/3, right to left. The PIC slot numbers are located above FPC0, and below FPC1. The number of ports on a PIC depends on the type of PIC.

Connecting M10i PIC Cables on page 63•

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.

The M10i routerhas a maximum throughput of3.2 Gbpsfull duplex for eachFPC. Inserting a combination of PICs with an aggregate higher than the maximum throughput is supported, but constitutes oversubscription of the FPC.

Page 35

Chapter 2: M10i Hardware Components

Figure 4: M10i PIC Location

PICs are hot-removable and hot-insertable. AremovedPIC no longer receives ortransmits data, and removing or inserting a PIC briefly interrupts forwarding of traffic through the remaining PICs.

Documentation

Most PICs supported on the M10i router have the following components.

•

One or more cable connector ports—Accept a network media connector.

•

LEDs—Indicate PIC and port status. Most PICs have an LED labeled STATUS on the PIC faceplate. Some PICs have additional LEDs, often one per port. The meaning of the LED states differs for various PICs. For more information, see the description for each PIC.

•

Ejector lever—Controls the locking system that secures the PIC in the card cage.

Some PICs acceptsmall form-factor pluggables (SFPs), which are fiber-optic transceivers that can be removed from the PIC. Various SFPs have different reach characteristics. You can mix them in a single PIC and change the combination dynamically. SFPs are hot-removable and hot-insertable, asdescribed in“M10i Field-ReplaceableUnits (FRUs)” on page 99. For information about PICs that use SFPs, see the “Cables and connectors” section for each PIC.

M10i Compact Forwarding Engine Board (CFEB) and Enhanced Compact Forwarding Engine Board (CFEB-E) Description

The Compact Forwarding Engine Board (CFEB)or EnhancedCompact Forwarding Engine Board (CFEB-E) performs route lookup, filtering, and switching on incoming datapackets, then directs outbound packets to the appropriate FPC for transmission to the network. It can process 15 million packets per second (Mpps).

One or two CFEBs or CFEB-Es can be installed into the midplane from the rear of the chassis, as shown in Figure 2 on page 6.

CAUTION: The M10i Internet router does not support a mixture of CFEB and

CFEB-E hardware.If youinstall two devices,they must both be CFEBs or they must both be CFEB-Es.

Only one CFEB or CFEB-E is active at a time; the optional second CFEB or CFEB-E is in standby mode. By default, the CFEB or CFEB-E in slot CFEB 0 is active. To modify the default,include theappropriate cfeb statementat the[edit chassis redundancy] hierarchy level of the configuration, as described in the section about CFEB or CFEB-E redundancy in the Junos OS System Basics Configuration Guide.

CFEBs or CFEB-Es are hot-pluggable when you replace a CFEB with a CFEB or a CFEB-E with a CFEB-E, as described in “M10i Field-Replaceable Units (FRUs)” on page 99. To upgrade from a CFEB to a CFEB-E or to downgrade from a CFEB-E to a CFEB requires a system reboot as described in “Upgrading or Downgrading an M10i CFEB or CFEB-E” on page 106.

Removing the standby CFEB or CFEB-E has no effect on router function. If the active CFEB or CFEB-E fails or is removed from the chassis, the effect depends on how many CFEBs or CFEB-Es are installed:

NOTE: For specific information about CFEB or CFEB-E components (for example, the amount of SDRAM), issue the show chassis cfeb command.

Page 37

Chapter 2: M10i Hardware Components

•

If there is one CFEB or CFEB-E, forwarding halts until the CFEB or CFEB-E is replaced and functioning again. For a minimum configuration, it takes approximately 2 minutes for the replaced CFEB or CFEB-E to boot and become active; reading in router configuration information can take additional time, depending on the complexity of the configuration.

•

If there are two CFEBs or CFEB-Es, forwarding halts while the standby CFEB or CFEB-E boots and becomes active, which takes approximately 1 minute; synchronizing router configuration information can take additional time, depending on the complexity of the configuration.

For CFEBor CFEB-E replacement instructions, see “Replacing, Upgrading, or Downgrading an M10i CFEB or CFEB-E” on page 103.

The CFEB orCFEB-E communicates with the Routing Engineusing a dedicated 100-Mbps Fast Ethernet link that transfers routing table data from the Routing Engine to the forwarding table in the integrated ASIC. The link is also used to transfer from the CFEB or CFEB-E to the Routing Engine routing link-state updates and other packets destined for the router that have been received through the router interfaces.

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.

M10i Routing Engine Description

The Routing Engine runs Junos OS. Thesoftware 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.

For a description of the Routing Engine's role in router architecture, see “M10i Routing Engine Architecture Overview” on page 33.

NOTE: The M10i routersupports the RoutingEngine 400 and Routing Engine

850.

One or two Routing Engines can be installed into the midplane from the front of the chassis, as shown in Figure 1 on page 6. If two Routing Engines are installed, the High-Availability Chassis Manager (HCM) determines which is the master and which is backup (in standby mode and so performs no functions). By default, the Routing Engine in the slot labeled RE0 is the master. To change the default master Routing Engine, include the appropriate [edit chassis redundancy routing-engine] statement in the configuration, as described in the section about Routing Engine redundancy in the Junos OS System Basics Configuration Guide.

The Routing Engine is hot-pluggable, as described in “M10i Field-Replaceable Units (FRUs)” onpage 99. If two Routing Engines are installed, removalor failure of thebackup Routing Engine does not affect router function. Removal or failure of the master Routing Engine affects forwarding and routing based on the high availability configuration:

NOTE: If two Routing Engines are installed, they must both be the same hardware model.

Page 42

M10i Multiservice Edge Router Hardware Guide

•

Dual Routing Engines without any high availability features enabled—Traffic is interruptedwhile the Packet Forwarding Engine is reinitialized.All kerneland forwarding processes are restarted. When the switchover to the new master Routing Engine is complete, routing convergence takes place and traffic is resumed.

•

Graceful Routing Engine switchover (GRES) is enabled—Graceful Routing Engine switchover preserves interface and kernel information. Traffic is not interrupted. However, graceful Routing Engine switchover does not preserve the control plane. Neighboring routers detect that the router has restarted and react to the event in a manner prescribed by individual routing protocol specifications. To preserve routing without interruption during a switchover, graceful Routing Engine switchover must be combined with nonstop active routing.

•

Nonstop active routing is enabled (graceful Routing Engine switchover must be configured for nonstopactive routing to be enabled)—Nonstopactive routing supports Routing Engine switchover without alerting peer nodes that a change has occurred. Nonstop active routing uses the same infrastructure as graceful Routing Engine switchover to preserve interface and kernel information. However, nonstop active routing also preservesrouting information and protocol sessions by running the routing protocol process (rpd) on both Routing Engines. In addition, nonstop active routing preserves TCP connections maintained in the kernel.

•

Gracefulrestart isconfigured—Graceful restartprovides extensions torouting protocols so that neighboring helper routers restore routing information to a restarting router. These extensions signal neighboring routers about the graceful restart and prevent the neighbors from reacting to the router restart and from propagating the change in state to the network during the graceful restart period. Neighbors provide the routing information that enables the restarting router to stop and restart routing protocols without causing network reconvergence. Neighbors are required to support graceful restart. The routing protocol process (rpd) restarts. Agraceful restart intervalis required. For certain protocols, a significant change in the network can cause graceful restart to stop.

If you do not configure graceful Routing Engine switchover, graceful restart, or nonstop active routing, you can configure automatic Routing Engine mastership failover. For information about configuring automatic mastership failover, see the Junos OS System Basics Configuration Guide.

NOTE: Router performance might change if the backup Routing Engine's

configuration differs from the former master's configuration. For the most predictable performance, configure the two Routing Engines identically, except for parameters unique to each Routing Engine.

NOTE: For informationabout configuringgracefulRouting Engine switchover, gracefulrestart, and nonstop activerouting, see theJunos OS High Availability Configuration Guide.

Page 43

Chapter 2: M10i Hardware Components

NOTE: The first supported release for graceful Routing Engine switchover

and nonstop active routing on the M10i router is Junos OS Release 6.1 and Junos OS Release 8.4, respectively. However, for graceful Routing Engine switchover we recommend Junos OS Release 7.0 or later. Graceful restart software requirements are dependent on the routing protocols configured on the router. For the minimum software requirements for graceful restart, see the Junos OS High Availability Configuration Guide.

For replacement instructions, see “Replacing the M10i Routing Engine” on page 131.

M10i Routing Engine Interface Ports

Each Routing Engine has a set of ports for connecting to one or more external devices on which system administrators can issue Junos OS command-line interface (CLI) commands to manage the router (see “M10i Routing Engine 850 LEDs” on page 21).

The ports with the indicated label in each set function as follows:

•

AUX/MODEM— Connects the Routing Engine to a laptop, modem, or other auxiliary

device through an RS-232 (EIA-232) serial cable.

•

MGMT—Connectsthe RoutingEngine through an Ethernet connectionto 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.

To the left of each MGMT port is a link status indicator, which lights to show that a link has been established over the Ethernet connection. To the right of each MGMT port is an activity indicator, which flashes when data is being transferred.

•

CONSOLE—Connects the Routing Engine to a system console through an RS-232

(EIA-232) serial cable.

For information about the pinouts for the connectors, see “RJ-45 Connector Pinouts for the M10i Routing Engine MGMT Port” on page 201.

M10i High-Availability Chassis Manager (HCM) Description

The High-Availability Chassis Manager (HCM) works with its companion Routing Engine to provide controland monitoringfunctions for routercomponents. The HCM also displays alarm status and takes PICs online and offline.

Two HCMs are installed into the midplane from the front of the chassis, as shown in Figure 1 on page 6. The master HCM performs all functions and provides PIC removal buttons for the first FPC. The backup HCM provides PIC removal buttons for the second FPC. The HCM in the slot labeled HCM0 is paired with the Routing Engine in the slot labeled RE0. Likewise,the HCM inthe slotlabeled HCM1is pairedwith the Routing Engine in the slot labeled RE1. By default, the HCM in the slot labeled HCM0 is the master.

NOTE: When HCM mastership changes because of failure, Routing Engine

mastership will change as well. For a description of Routing Engine mastership, see “M10i Routing Engine Description” on page 15.

Page 48

M10i Multiservice Edge Router Hardware Guide

The HCM performs the following functions:

•

Monitoring and control of router components—The HCM collects statistics from all sensors in the system. When it detects a failure or alarm condition, it sends a signal to the Routing Engine, which generates control messages or sets an alarm. The HCM also relays control messages from the Routing Engine to the router components.

•

Controlling component power-up and power-down—The HCM controls the power-up sequence of router components as they start and powers down components when their offline buttons are pressed.

•

Signaling of mastership—In a router with more than one Routing Engine, the HCM signals to all router components which Routing Engine is the master and which is the standby.

•

Alarm display—If an alarm exists, the HCM displays the alarm condition. For more information, see “M10i HCM Alarm LEDs” on page 23.

•

PIC removal—If a PIC offline button is pressed, the HCM relays the request to the CFEB or CFEB-E, which takes the PIC offline and informs the Routing Engine. Other PICs are unaffected, and system operation continues. For more information, see “M10i HCM LEDs” on page 23.

Figure 8: M10i High-Availability Chassis Manager

Each HCM (shown in Figure 8 on page 22) has the following components:

•

100-Mbps Fast Ethernet switch—Carries signals and monitoring data between router components.

•

Two LEDs—Indicate HCM status. There is a green one labeled PWR and an blue one labeled MSTR. “M10i HCM LEDs” on page 23 describes the LED states.

•

Alarm LEDs—Display alarm conditions, if any exist.

•

PIC offline buttons—Relays a request to the CFEB or CFEB-E, which prepares a PIC for removal from the router, or brings the PIC online when it is replaced.

Offline buttonsfor one row of PICsare located on each HCM (see Figure 8 onpage 22). Pressing the button relays a request to the CFEB or CFEB-E, which prepares the PIC for removal from the router, or brings it online when it is replaced. The HCM in slot 0 controls PICs on FPC 0. The HCM in slot 1 controls PICs on FPC 1. The buttons are labeled with the PIC slot numbers. The PIC slots on the upper FPC are numbered from

M10i Power System Description

The router uses either AC or DC power. You can install up to three AC power supplies or four DCload-sharing power supplies at the bottom rearof 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. When the power supplies are installed and operational, they automatically share the electrical load.

On steadilyRed

On steadilyYellow

Critical alarm LED—Indicates a critical condition that can cause the router to stop functioning, such as component removal, failure, or overheating.

Warningalarm LED—Indicates aserious but nonfatal error condition, such as a maintenance alert or a significant increase in component temperature.

An enable control pin 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.

Redundant power supplies are hot-removable and hot-insertable, as described in “M10i Field-Replaceable Units (FRUs)” on page 99.

Page 51

NOTE: After powering off a power supply, wait at least 60 seconds before

turning itback on. Afterpowering 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 bootsas thepower supplycompletesits startupsequence. If the Routing Engine finishes booting and you need to power off the router again, see “Powering Off an M10i Router” on page 71.

After a power supply is powered on, it can take up to 60 seconds for status indicators—suchasthe output statusLED on thepower supply, thecommand display output, and messages on the LED display on the craft interface—to indicatethat the powersupply is functioning normally. Ignore errorindicators that appear during the first 60 seconds.

M10i Fan Tray Description

The fan trays installed along each side of the chassis draw room air into the chassis to maintain an acceptable operating temperature for the Routing Engine, PICs, CFEB or CFEB-E, and other components. The router's cooling system consists of two fan trays, located along the left and right side of the chassis, that provide side-to-side cooling (see Figure 13 on page 28). They connect directly to the router midplane. Each fan tray is a single unit containing eight individually fault-tolerant fans. If a single fan fails, the remaining fans continue to function indefinitely. For proper airflow, the primary fan tray should be installed in slot 1 (the left slot looking at the chassis from the rear) and must be installed for proper cooling at all times. The redundant fan tray, if present, should be installed in slot 0 on the right. This fan tray provides additional cooling and redundancy.

M10i Cable Management System Description

The cable management system consists of racks that attach vertically to each side of the chassis at the front, as shown in Figure 14 on page 29. Pass PIC cables through the slots in the racks to keep the cables organized and securely inplace, 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.

M10i 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 15 on page 31 illustrates the relationship between the Packet Forwarding Engine and the Routing Engine.

M10i Packet Forwarding Engine Architecture Overview

The Packet Forwarding Engine performs Layer 2 and Layer 3 packet switching. It can forward up to 15 million packets per second (Mpps) for all packet sizes. The aggregate throughput is 4 gigabits per second (Gbps) full duplex per FPC (8 Gbps full-duplex total throughput rate). The Packet Forwarding Engine is implemented in application-specific integrated circuits (ASICs). It uses a centralized routelookup engine and shared memory.

The Packet Forwarding Engine architecture includes the following components:

•

Midplane—Transports packets, notifications, and other signals between the PICs 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 16 on page 33):

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.

5. The integratedASIC reassembles data cells storedin sharedmemory intodata packets

as they are ready for transmission and passes them to the outbound networking interface.

6. The outbound networking interface transmits the data packets.

M10i Routing Engine Architecture Overview

The Routing Engine is an Intel-based PCI platform running 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 anindependent operatingsystem. The Junos kernel supports Junos system processes, whichhandle system management processes, routingprotocols, and control functions (see Figure 17 on page 34).

The Routing Engine has a dedicated 100-Mbps internal connection to the Packet Forwarding Engine.

Page 60

M10i Multiservice Edge Router Hardware Guide

Figure 17: 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 topof a kernel that interacts withthe Packet ForwardingEngine. 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:

•

Processing of routing protocol packets—The Routing Engine handles all packets that concern routing protocols, freeingthe Packet Forwarding Engine to handle only packets that represent Internet traffic.

•

Softwaremodularity—Becauseeach 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 routingprotocolis implemented witha complete set ofInternet features and provides full flexibilityfor 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 andchange management—Configurationfiles, system images, andmicrocode 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.

Page 61

Chapter 3: M10i System Architecture Overview

The Routing Engine constructs and maintains one or more routing tables (see Figure 18 on page 35). 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.

M10i Rack Requirements

The router must be installed in a rack. Many types of racks are acceptable, including 4-post (telco) racks and open-frame racks. An example of a open-frame rack appears in Figure 19 on page 42.

The following sections describe rack requirements:

•

•

Connection to Building Structure on page 43

Page 67

M10i Rack Size and Strength

The router is designed for installation ina 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).

With the use of adapters, the router is designed to fit into a 600-mm-wide and 600-mm-deep 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). Use approved wing devices to narrow the opening between the rails.

The rack rails must be spaced widely enough to accommodate the router chassis's external dimensions: 8.7 in. (22.1 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. (48.3 cm). The spacing of rails and adjacent racks must also allow for the clearances around the router and rack that are specified in “Clearance Requirements for Airflow and Hardware Maintenance” on page 43.

Chapter 4: Preparing the Site for M10i Router Installation

The chassis height of 8.7 in. (22.1 cm) is approximately 5 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 eight router in a rack that has at least 40 U (70 in. or 1.78 m) of usable vertical space.

The rack must be strong enough to support the weight of the fully configured router, up to approximately 79 lb (35.8 kg). If you stack eight fully configured routers in one rack, it must be capable of supporting about 632 lb (286.7 kg).

Clearance Requirements for Airflow and Hardware Maintenance

When planning the installation site, you must allow sufficient clearance around the rack (see Figure 20 on page 44):

•

For the cooling system to function properly, the airflow around the chassis must be unrestricted. Figure 13 on page 28 depicts the airflow in the router. 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.

NOTE: Werecommend that you do not install the router in a cabinet.If you

mount therouter in a cabinet, be sure that ventilationis sufficientto prevent overheating.

•

For service personnel to remove and install hardware components, there must be adequate space at the front and back of the router. At least 24 in. (61 cm) is required both in front of and behind the router. NEBS GR-63 recommends that you allow at least 30 in. (76.2 cm) in front of the rack and 24 in. (61 cm) behind the rack.

Connecting M10i PIC Cables

Now connect PICs to the network by plugging in network cable. To connect cable to the PICs (see Figure 31 on page 64, which shows a fiber-optic PIC):

1. Have ready a length of the type of cable used by the PIC. For cable specifications, see

the M10i Multiservice Edge Router PIC Guide.

2. If the PIC cable connector port is covered by a rubber safety plug, remove the plug.

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

ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a transceiver emit laser light that can damage your eyes.

CAUTION: 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.

3. Insert the cable connector into the cable connector port on the PIC faceplate.

4. Arrange the cable in the cable management system 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 in the cable management system. Placing fasteners on the loop helps to maintain its shape.

CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius.An arc smallerthan a fewinches in diametercan damagethe cable and cause problems that are difficult to diagnose.

voltage across the leads of the DC power cables is 0 V. Ensure that there is no chance that the cable leads might become active during the procedure.

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 DC power cablesthat attach to the terminal studs on the powersupply faceplate.You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and (–) to indicate their polarity.

2. For each power supply, verify that the power switch on the power supply faceplate is

in the OFF (O) position.

3. Verify that a licensed electrician has attached a listed DC power cable lug to each

power source cable.

4. Loop the DC power cables through the hook located on the faceplate to the right of

the field-wiring terminals.

5. Depending on the type of DC power cable lugs used, loosen or remove the screws on

the field-wiring terminals.

6. Insert the DC 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 DC 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.

NOTE: The DC power supplies in slots P/S 0 and P/S 1 must be powered

by dedicated powerfeeds derived from feed A, and the DC power supplies in slots P/S 2 andP/S3 must be poweredby dedicated power feedsderived from feed B. Thisconfigurationprovides the commonly deployed A/B feed redundancy for the system.

Disconnecting Power on an DC-Powered M10i Router

To disconnect DC power from the router:

1. Power off the router (see “Powering Off an M10i Router” on page 71).

2. For each power supply, press the power switch on the DC power supply faceplate to

the OFF (O) position.

3. Shut off the power flowing from both external power sources, so that the voltage

across the leads of the DC power cables is 0 V. Ensure that there is no chance that the cable leads might become active during the procedure.

4. Using a number 1 Phillips screwdriver, turn the screw on each field-wiring terminal

counter-clockwise to loosen the terminal connector from around the cable.

5. Remove the cables from the terminal connectors and from the hook located on the

faceplate to the right of the field-wiring terminals.

6. Verify that the removed cables are not touching or blocking access to any router

components.

Powering Off an M10i Router

To power off the router:

1. Onan external management deviceconnected to the Routing Engine,issue the request

system halt both-routing-engines operational mode command. The command shuts

down the Routing Engines cleanly, sotheir state information is preserved. (Ifthe router contains only one Routing Engine, issue the request system halt command.)

user@host> request system halt both-routing-engines

Wait until a message appears on the console confirming that the operating system has halted.

Halt the system ? [yes,no] (no) yes

NOTE: The CFEB or CFEB-E might continue forwarding traffic for approximately 5 minutes after the request system halt command has been issued.

For more information about the commands, see the Junos OS System Basics and Services Command Reference.

*** FINAL System shutdown message from user@host ***

Configuring Junos OS

•

Initially Configuring the M10i Router on page 73

Initially Configuring the M10i Router

The router is shipped with the Junos OS preinstalled and ready to be configured when the router is powered on. There are three copies of the software: one on a CompactFlash card (if installed) in the Routing Engine, one on the hard disk in the Routing Engine, and one on a PC card that can be inserted into the slot in the Routing Engine faceplate.

When the router boots, it first attempts to start 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 (if installed), 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

This procedure connects one router to the network but does not enable it to forward traffic. For complete information about enabling the router to forward traffic, including examples, see the Junos OS configuration guides.

To configure the software:

1. Verify that the router is powered on, as described in “Powering On an AC-Powered

M10i Router” on page 66 or “Powering On a DC-Powered M10i Router” on page 69.

2. Log in as the root user. There is no password.

3. Start the CLI.

root@% cli root>

4. Enter configuration mode.

root> configure Entering configuration mode. [edit] root@#

5. Add a password to the root administration user account. Enter a clear-text password.

For information about using anencrypted password, or an SSH public key string (DSA or RSA), see the Junos OS System Basics Configuration Guide.

[edit] root@# set system root-authentication plain-text-password New password: password Retype new password: password

6. Create a management console user account.

[edit] root# set system login user user-name authentication plain-text-password New Password: password Retype new password: password

7. Set the user account class to super-user.

[edit] root# set system login user user-name class super-user

8. Configure the name of the router. If the name includes spaces, enclose the name in

quotation marks (“ ”).

[edit] root@# set system host-name host-name

NOTE: The DNSserver doesnot use the host name toresolveto the correct IP address. This host name is used to display the name of the routing engine in the CLI. For example, this host name shows on the command line prompt when the user is logged on to the CLI:

user-name@host-name>

9. Configure the IP address of the DNS server.

10. Configure the router’s domain name.

[edit] root@# set system domain-name domain-name

[edit] root# set system name-server address
