TX Matrix Router Description

The Juniper Networks TX Matrix router is the centralized switch fabric of the routing matrix, which is a terabit routing system interconnecting up to four T640 Core Routers to deliver up to 2.56 terabits per second (Tbps) of subscriber switching capacity. The routing matrix multichassis architecture provides scalable growth for aggregation and core services for voice, video, and data networks. It provides a flexible and cost-effective means to simplify large point-of-presence (POP) and central office environments. The routing matrix delivers high-availability services from tunnel services, ATM, DS3, OC3/STM1, OC12/STM4, Gigabit Ethernet, 10-Gigabit Ethernet, OC48/STM16, OC192/STM64, and other high-speed interfaces.

The routing matrixleverages the intelligent virtual services capabilitiesof Junos OS, which enable you to create multiple application-specific logical networks over a single physical topology. This gives you the ability to virtually separate traffic types that require unique network attributes—such as ATM or high-priorityvoice over IP (VoIP) and third-generation (3G) mobile traffic—from bulk transit IP traffic.

Documentation

The TX Matrix router architecture cleanly separates control operations from packet forwarding operations. This design eliminates processing and traffic bottlenecks, permitting the TX Matrix router to achieve terabit performance levels. Control operations in the TX Matrix router are performed by the host subsystem, which runs Junos OS to handle traffic engineering and configuration management. High-availability, interchassis communicationsare provided byan EthernetLAN thatinterconnectsthe hostsubsystems in the TX Matrix router and the T640 routers.

The TX Matrix router is a modular, rack-mountable system. One TX Matrix router can be installed in one standard 19-in. wide, 78-in. high, EIA telco rack.

TX Matrix System Architecture Description

The routing matrix has two main architectural components, the control plane and the forwarding plane:

•

The control plane in the routing matrix is formed by the connection of the host subsystems—TX-CBs in the TX Matrix router and T-CBs in the T640 routers —and the Routing Engines.

•

The forwarding plane in the routing matrix is formed by the switch fabric—TX-SIBs in the TX Matrix router and T640-SIBs in the T640 routers—and the Packet Forwarding Engines.

The Routing Engines and the Packet Forwarding Engines perform their primary tasks independently. This arrangement streamlines routing control and forwarding and runs Internet-scale backbone networks at high speeds. Figure 1 on page 6 shows the relationship between the Routing Engines and the Packet Forwarding Engines.

TX Matrix Routing Engine Functions

The TX Matrix Routing Engine handles all routing protocols, as well as the software processes that control the TX Matrix interfaces and user access to the TX Matrix router. All Routing Engines in the routing matrix run software processes that control chassis components and system management. For more information about the processes, see “Routing Engine Software Components” on page 149.

The Routing Engines include 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 handleonly 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.

Page 39

Chapter 2: TX Matrix System Architecture Overview

•

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 TX Matrix router supports functions such as alarm handling and packet countingon every port, without degradingpacket-forwarding performance.

The TX Matrix Routing Engine constructs and maintains one ormore routingtables. From the routingtables, the Routing Engine derives a tableof activeroutes, called theforwarding table, which is then copied to the T640 routers (see Figure 2 on page 8). The Junos kernel running on each T640 router's Routing Engine copies its forwarding table to all Packet Forwarding Engines in the router. The design of the ASICs allow the forwarding table in the Packet Forwarding Engine to be updated without interrupting forwarding performance.

TX Matrix Routing Matrix Control Plane Architecture

The routing matrix contains two controlplanes. Allmaster Routing Enginesin the TX Matrix router and T640 routers are on one control plane; all backup Routing Engines are on another control plane (see Figure 3 on page 9). To manage the Routing Engines on a control plane, you must be logged into the Routing Engine in the TX Matrix router on that control plane. For example, you must be logged into the backup Routing Engine in the TX Matrix router to upgrade the software of all backup Routing Engines in the routing matrix.

Page 41

Chapter 2: TX Matrix System Architecture Overview

Figure 3: Routing Matrix Routing Engine Connections

The TX Matrix Routing Engine connects to a high-speed switch through a 1-Gbps link within the host subsystem. The switch provides a 100-Mbps link to each T640 Routing Engine. The 100-Mbps links are provided through the UTP Category 5 Ethernet cable connections between the TX-CIPs and the T-CBs in the T640 routers.

The kernel synchronization process running on each T640 router Routing Engine synchronizes the TX Matrix Routing Engine's forwarding table with the forwarding table on a T640 router. The Junos kernel running on each T640 router Routing Engine copies its forwarding table to all Packet Forwarding Engines in each T640 router.

Figure 4 on page 10 illustrates the control plane architecture.

Control Plane Connections Between the TX Matrix Router and T640 Router

The control plane connections between the T640 routers and the TX Matrix router are provided by UTP Category 5 Ethernet cables between the RJ-45 ports on the TX-CIPs in the TX Matrix router and the T-CBs in the T640 routers. The maximum length supported is 100 m. The UTP Category 5 cables do not have to be the same length. The cable wiring is straight-through (not crossover).

Table 3 on page 11shows these connections.Each column represents aTX-CIP (TX-CIP-0 and TX-CIP-1), and each cell within a column represents a port on that TX-CIP. Each cell specifies the TX-CIP port (LCC0 through LCC3) and its connection to the port labeled

CIP on a T-CB in one of the T640 routers. For example, port LCC0 on TX-CIP-0 is

connected to T-CB-0 in chassis LCC0, port LCC1 on TX-CIP-0 is connected to T-CB-0 in chassis LCC1, and so on.

TX Matrix Routing Matrix Switch Fabric Architecture

The routing matrix switch fabric consists of five data switching planes. The switch fabric uses ASICs to perform high-speed packet forwarding between the T640 routers. Each TX-SIB and the T640-SIBs connected to it represent a data switching plane that spans the TX Matrix router and all T640 routers in the routing matrix. The switching planes are connected by high-speed optical links within fiber-optic array cables.

Consider a packet that enters a T640 router and is destined for another T640 router in the routing matrix. When the packet enters an interface on a PIC in a T640 router, it is forwarded to the switch fabric by a Packet Forwarding Engine on that router (see T640 Core Router Hardware Guide for moredetails). The packet is forwarded through the switch fabric from the source T640 router, through the TX Matrix router, to the target T640

Page 45

router. The switch fabric allows high-priority traffic from any Packet Forwarding Engine to an egress Packet Forwarding Engine to be given preferential treatment overlow-priority traffic from any other Packet Forwarding Engine. The Packet Forwarding Engine on the target T640 router forwards the packet to the destination PIC and interface.

The switch fabric can forward up to 3 Gpps. The maximum aggregate throughput rate for the TX Matrix router is 2.56 Tbps (full duplex). Figure 6 on page 13 illustrates the switch fabric architecture.

Switching Plane Connections Between the TX Matrix Router and T640 Routers

The switching plane connections between the T640 routers and the TX Matrix router are provided by the fiber-optic array cables that connect the T640-SIBs to the TX-SIBs. Table 4 on page 14shows theseconnections. Each columnrepresents a TX-SIB (TX-SIB-0 through TX-SIB-4), and each cell within a column represents an adapter on that TX-SIB. Each cell specifies the TX-SIB adapter (LCC0 through LCC3) and its connection to a T640-SIB in one of the T640 routers. For example, adapter LCC0 on TX-SIB-0 is connected to T640-SIB-0 in chassis LCC0, adapter LCC1 on TX-SIB-0 is connected to

T640-SIB-0 in chassis LCC1, and so on.

The cable connections provided in Table 4 on page 14 apply to routing matrix configurations using from one through four T640 routers. For example, if you have a single T640 router in your configuration, the connections from each TX-SIB to chassis

LCC0 are presented in the first row of the table. If you have two T640 routers in your

configuration,the connections fromeach TX-SIB tochassis LCC0 and LCC1are presented in the first two rows of the table, and so on.

TX Matrix Component Redundancy

The TX Matrix router is designed so that no single point of failure can cause the entire system to fail. The following major hardware components are redundant:

•

TX-SIBs—The TX Matrix router has five TX-SIBs. Each TX-SIB and the T640-SIBs connected to it represent a data switching plane that spans the TX Matrix router and all T640 routers in the routing matrix. One ofthe five TX-SIBs—usually TX-SIB-0—acts as a backup to the remaining four TX-SIBs. If a TX-SIB or T640-SIB fails, the backup data switching plane becomes active and traffic forwarding continues without any degradation.When thefailedcomponent isreplaced, the data switching plane in which it resides becomes the new backup. If the failed component is not replaced, and a TX-SIB or T640-SIB in an active data switching plane fails, only that component is taken offline.

•

Host subsystem—The hostsubsystem consists of a RoutingEngine functioningtogether with a TX-CB. The TX Matrix router can have one or two host subsystems. If two host subsystems are installed, one functions as the master and the other functions as the backup. If the master host subsystem (or either of its components) fails, the backup can take over asthe master. To operate, each hostsubsystem requires aRouting Engine installed in an adjacent slot to a TX-CB.

If theRouting Enginesare configured for graceful switchover, the backup Routing Engine automatically synchronizes its configuration andstate with the master RoutingEngine. Any update to the master Routing Engine state is replicated on the backup Routing Engine. Ifthe backupRouting Engine assumes mastership, packet forwarding continues through theTX Matrix router without interruption. For more informationabout graceful switchover, see the Junos OS High Availability Configuration Guide.

NOTE: We recommend that you run Junos OS Release 7.3 or later on the

TX Matrix router to support graceful switchover.

•

TX-CIPs—The TX Matrix router has two TX-CIPs. Each TX-CIP provides the ports for its corresponding host subsystem (Routing Engine and TX-CB) in the TX Matrix router and the control plane connections to the Control Boards (T-CBs) in up to four T640 routers.

If the master TX-CIP fails, the backup TX-CIP provides redundant connections to the active host subsystemin the TX Matrix router andthe activeT-CBs in the T640 routers. In thiscase, the Routing Engines in the TX Matrix routerand T640 routers donot perform a switchover to their backups.

•

Power supplies—The TX Matrix router has two power supplies, which share the load evenly. If one power supply fails, the other power supply can provide full power to the TX Matrix router indefinitely.

•

Cooling system—Thecooling system has redundantcomponents, whichare controlled by the host subsystem. If one of the fans fails, the host subsystem increases the speed of the remaining fans to provide sufficient cooling for the TX Matrix router indefinitely.

TX Matrix Switch-Card Chassis (SCC) Description

The TX Matrix SCC is a rigid sheet metal structure that houses all the other system components (see Figure 8 on page 20 and Figure 9 on page 21). The chassis measures

44.5 in. (113.0 cm) high, 17.4 in. (44.2 cm) wide, and 31.4 in. (79.8 cm) deep. The chassis installs into standard 19-in. equipment racks or telco center-mount racks. One TX Matrix router can be installed into a standard (44-U) rack, if the rack can handle the maximum configuration weight of 495 lb (225 kg).

The chassis includes the following features (see Figure 8 on page 20 and Figure 9 on page 21):

•

A pair of metal flanges and a pair of metal brackets used for mounting the chassis in a four-post rack or cabinet or open-frame rack.

•

Upper and lower handles on each side to facilitate positioning the TX Matrix router in the rack. Do not use the handles to lift the TX Matrix router.

•

Two electrostatic discharge points (banana plug receptacles), one on each TX-CIP and one in the rear.

WARNING: Before removing or installingcomponents of aTX Matrix 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 TX Matrix router.

The TX Matrix router must be connected to earth ground during normal operation.

TX Matrix Midplane Description

The midplane is located in the center of the chassis and forms the rear of the TX-SIB card cage (see Figure 10 on page 22). The TX-SIBs install into the midplane from the front of the chassis, and the Routing Engines and TX-CBs install into the midplane from the rear of the chassis.The power supplies and cooling system components also connect to the midplane.

Page 54

TX Matrix Hardware Guide

The midplane performs the following major functions:

•

Power distribution—The TX Matrix power supplies are connected to the midplane, which distributes power to all the TX Matrix components.

•

Signal connectivity—The midplane provides signal connectivity between all TX Matrix components for monitoring and controlling the system.

•

Redundancy connectivity—The midplane provides redundant paths for all critical connections.

TX Matrix Switch Interface Boards (TX-SIBs) Description on page 23

•

TX Matrix TX-SIB LEDs on page 24

TX Matrix Switch Interface Boards (TX-SIBs) Description

The TX-SIBs create the switch fabric for the TX Matrix router, providing up to a total of 3 billionpacketsper second(Gpps) of forwarding(see Figure 11on page24). Five TX-SIBs are installed vertically in the front of the TX Matrix router. The TX-SIBs are referred to as

TX-SIB-0 through TX-SIB-4 (left to right).

One of the five TX-SIBs—usually TX-SIB-0—acts as a backup to the remaining four TX-SIBs. If a TX-SIB or T640-SIB fails, the backup data switching plane becomes active and traffic forwarding continues without any degradation. When the failed component is replaced, the data switching plane in which it resides becomes the new backup. If the failed component is not replaced, and a TX-SIB or T640-SIB in an active data switching plane fails, only that component is taken offline.

TX-SIBs are hot-removable and hot-insertable.

Each TX-SIB consists of the following components:

•

Switch fabric ASICs.

•

A high-speed fiber-optic link to each T640 router in the routing matrix (a total of four links labeled LCC0 through LCC3). The four links represent one data switching plane across four T640 routers.

•

Two status LEDs located to the right of each fiber-optic array adapter on the TX-SIB faceplate. Table 5 on page 24 describes the functions of these LEDs.

•

An ONLINE/OFFLINE button next to each fiber-optic array adapter that brings the corresponding interface and T640-SIB online and offline.

TX Matrix Routing Engine Description

The Routing Engine in the TX Matrix router maintains the routing tables used by the routing matrix and controls the routing protocols that run on the routing matrix. The TX Matrix router provides all routing tables, along with updates, to each T640 router in the routing matrix.

You can install one or two Routing Engines in the TX Matrix router. The Routing Engines install into the upper rear of the chassis in the slots labeled RE0 and RE1. If two Routing Engines are installed, one functions as the master and the other acts as the backup. If the master Routing Enginefails oris removed, and the backup is configured appropriately, the backup restarts and becomes the master.

NOTE: Werecommendthat yourun thesame JunosOS releaseon the master

and backup Routing Engines. If you elect to run different Junos OS releases on the Routing Engines, a change in Routing Engine mastership can cause one or all T640 routers tobe logicallydisconnectedfromthe TX Matrixrouter.

Documentation

Each Routing Engine requires a TX-CB to be installed in the adjacent slot. RE0 installs below CB0, and RE1 installs above CB1. A Routing Engine does not power on if no TX-CB is present in the adjacent slot.

The ports forconnecting theRouting Engine toexternal management devices arelocated on the corresponding TX-CIP. The ports on TX-CIP-0 connect to the Routing Engine in slot RE0, and the ports on TX-CIP-1 connect to the Routing Engine in slot RE1.

The TX Matrix router supports the following Routing Engines:

•

RE-600-2048 (EOL)

•

RE-1600-2048 (EOL)

•

RE-A-2000-4096

TX-CIP Description

Chapter 3: TX Matrix Hardware Components Overview

The TX Matrix router contains one or two TX-CIPs—one for each Routing Engine—that install vertically into the front left of the chassis in the slots labeled CIP0 and CIP1 (see Figure 21 on page 39). The TX-CIPs are referred to as TX-CIP-0 and TX-CIP-1. The front electrostatic discharge point is located near the bottom of the TX-CIP.

The TX-CIP is hot-removable and hot-insertable.

Figure 21: TX-CIP

Page 72

TX Matrix Hardware Guide

Control Plane Ports

Routing Engine Ports

Each TX-CIP contains four RJ-45 ports labeled LCC0 through LCC3. These ports provide T640 router control by connecting to T-CBs in up to four T640 routers through UTP Category 5 Ethernet cables. TX-CIP-0 and TX-CIP-1 are used to connect to T-CB-0 and

T-CB-1 in each T640 router.

NOTE: The RJ-45 ports labeled LCC4 through LCC7 on a TX-CIP are reserved for future use.

Each TX-CIP hasthree portsfor connecting the corresponding hostsubsystem to external management devices (see Figure 21 on page 39). From these management devices, you can use the CLI to configure the TX Matrix router. The ports on TX-CIP-0 connect to the Routing Engine in slot RE0, and the ports on TX-CIP-1 connect to the Routing Engine in slot RE1.

Alarm Relay Contacts

•

One 10/100-Mbps ETHERNETport for connecting toa management network—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 LED labeled ETHERNET lights yellow or green for a 10-Mbps or 100-Mbps connection, and the LED labeled ACT lights green when traffic is passing through the port.

NOTE: If a TX Matrix router contains two host subsystems, connect both

TX-CIPs to your external management network.

•

CONSOLE—One asynchronous serialport for connectingthe Routing Engine to a system

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

•

AUXILIARY—One asynchronous serial port for connecting the Routing Engine to a

laptop, modem, or other auxiliary device through an RS-232 (EIA-232) serial cable.

Each TX-CIP hastwo alarm relay contacts—labeledRED ALARM and YELLOWALARM—for connecting the TX Matrix router to external alarm devices (see Figure 21 on page 39). Whenever a system condition triggers eitherthe redor yellow alarm on the craftinterface, the alarm relay contacts are also activated. The alarm relay contacts are located below the Routing Engine ports.

TX Matrix Power System Description

The TX Matrix router supports DC power only. The TX Matrix router has two load-sharing DC power supplies, located at the lower rear of the chassis in slots PEM0 and PEM1 (top to bottom). The power supplies connect to the midplane, which distributes the different output voltages produced by the power supplies to the TX Matrix router components, depending on their voltage requirements.

Each power supply has either an active circuitbreaker or an active current limiter for each output voltage it provides. There are no passive fuses in the TX Matrix router that must be replaced.

Chapter 3: TX Matrix Hardware Components Overview

Each power supply is cooled by its own internal cooling system.

The TX Matrix router supports these DC power supplies:

•

The two-input 160-A DC power supply is supported by Junos OS Release 5.3 and later.

•

The three-input 240-A DC power supply in 2-INPUT mode is supported by Junos OS Release 9.2 and later.

NOTE: Mixing a two-input160-A powersupplyand a three-input240-A power

supply in the same chassis is not supported during normal operations.

Figure 22: Two-Input 160-A DC Power Supply

Two-Input 160-A DC Power Supply Inputs

Each two-input 160-A power supply has two inputs—INPUT 1 and INPUT 0, from top to bottom—each with its own 80-A (@ –48 VDC) circuit breaker.

NOTE: All inputs on the two-input 160-A DC power supply in slot PEM0 must

be powered by dedicated power feeds derived from feed A, and all inputs on the two-input 160-A DC power supply in slot PEM1 must be powered by dedicated power feeds derived from feed B. This configuration provides the commonly deployed A/B feed redundancy for the system.

Table 12 on page 42 describes which components are powered by each input.

Two-Input 160-A DC Power Supply Load Sharing and Fault Tolerance

When the router is operating normally and both power supplies in a redundant power system are switched on, load sharing between them occurs automatically. When one power supply fails or is turned off, the other power supply immediately assumes the entire electrical load for the system. A single power supply with both inputs active can provide full power for as long as the router is operational. Table 13 on page 43 describes the behavior of the two-input160-A DC power supply and router if one of the inputs fails.

Cooling System Description

The cooling system components work together to keep all TX Matrix router components within the acceptable temperature range (see Figure 25 on page 48). If the ambient maximum temperature specification is exceeded and the system cannot be adequately cooled, the Routing Engine shuts down some or all of the hardware components.

Page 80

Air exhaust

TX Matrix Hardware Guide

Figure 25: Airflow Through the Chassis

Fan Tray Description

To function properly, the entire cooling system requires an unobstructed airflow and proper clearance around the site, as described in “TX Matrix Clearance Requirements for Airflow and Hardware Maintenance” on page 63.

The cooling system consists of the following components:

•

Two front fan trays

•

Rear fan tray

•

Front air filter

•

Rear air filter

The TX Matrix router cooling system contains two front and one rear fan tray (see Figure 8 on page 20 and Figure 9 on page 21). The fan trays each contain multiple fans that work in unison to cool the TX Matrix router components. The fan trays are hot-insertable and hot-removable. Figure 25 onpage 48 shows the airflow through the TX Matrix router.

•

The front fan trays each contain six fans and are interchangeable with each other. The front fan trays cool the components installed in the front card cage (the TX-SIBs, TX-CIPs, and midplane).

•

The rear fan tray contains eight fans and is not interchangeable with the front trays. The rear fan tray cools the components installed in the rear card cage (the Routing Engines and TX-CBs).

•

Each power supply has one fan that cools that power supply.

Page 81

Air Filter Description

Chapter 3: TX Matrix Hardware Components Overview

When the TX Matrix router is operating normally, the fans function at lower than full speed. The host subsystem constantly monitors the temperature detected by sensors on the midplane and TX Matrix router components. If a fan fails or the ambient temperature rises above a threshold, the host subsystem adjusts the speed of the remaining fans tomaintain proper cooling and keepthe temperature withinthe acceptable range. If the TX Matrix router temperature exceeds the acceptable maximum, the TX-CB turns off the power supplies. A red alarm is triggered when a fan fails, and a yellow alarm is triggered when a fan tray is removed.

CAUTION: To maintain proper cooling, do not operate the TX Matrix router

with the rear fan tray removed for more than 1 minute.

Air filters for both the front and rear fan trays help keep dust and other particles from entering the cooling system. The TX Matrix router has one front air filter and one rear air filter. The air filter is hot-insertable and hot-removable.

Figure 26: Fiber-Optic Array Cable

You can order cable lengths of 4 m, 5 m, 6 m, and 12 m from Juniper Networks. If you require cables longer than 12 m, you must order them directly from the manufacturer. Contact your Juniper Networks representative for more information.

Ethernet cables

DB-9 Serial Cables

Documentation

NOTE: A fiber-optic array connector is attached to each end of a fiber-optic array cable and plugs into a fiber-optic array adapter on a TX-SIB and a T640-SIB.

The UTP Category 5 Ethernet cables, which use straight-through wiring and RJ-45 connectors on each end, are used for controlling the T640 routers and for out-of-band management of the routing matrix. Controlling the T640 routers requires connections from the two TX-CIPs in the TX Matrix router to the T-CBs in the T640 routers. Out-of-band management requires connections from the TX-CIPs to external management devices.

These cables can be up to 100 m long.

The DB-9 serial cables are used to connect a system console or laptop computer to the TX-CIPs for local management of the routing matrix.

TX Matrix Cable Management System Description

The cable managementsystem consists ofthe comb panel assembly and the cableshelf assembly.

Figure 27 on page 51 shows the TX Matrix cable management system.

Figure 27: Cable Management System

Chapter 3: TX Matrix Hardware Components Overview

The comb panel assembly, which installs immediately above the TX-SIBs, consists of five combs—one comb above each TX-SIB. Each comb contains four teeth to organize and provide strain relief to the four fiber-optic array cables connected to the TX-SIB immediately below it. The fiber-optic array cables extend through the top of the cable comb so that you can route the cables to the T640 routers.

The cable shelf assembly routes and supports the fiber-optic array cables over the top of the TX Matrix router (see Figure 28 on page 52). The cable shelf assembly consists of four parallel shelves. Each shelf is used to route five fiber-optic array cables—and potentially a sixth spare cable—destined for a T640 router.

“TX Matrix DC Power Cable and Lug Specifications” on page 341

4. Locate sites for connection of system grounding.

“TX Matrix Chassis Grounding Specifications” on page 337

5. Calculate the power consumption and requirements.

“TX Matrix DC Power Requirements” on page 339

6. Verify that your rack meets the minimum requirements for the installation of the

TX Matrix router.

“Rack Requirements for TX Matrix Routers” on page 61

7. Plan rack location, including required space clearances.

Page 90

TX Matrix Hardware Guide

“TX Matrix Clearance Requirements for Airflowand Hardware Maintenance” onpage 63

See “Rack Requirements for TX Matrix Routers” on page 61.

8. If a rack is used, secure it to the floor and building structure.

See “Rack Requirements for TX Matrix Routers” on page 61.

9. Acquire cables and connectors:

•

Determine the number of cables needed based on your planned configuration.

•

Review the maximum distance allowed for each cable. Choose the length of cable based on the distance between the hardware components being connected.

See “TX MatrixCablesOverview” onpage49 and“TX Matrix Fiber-OpticArray Cable Considerations” on page 65.

10. Plan the cable routing and management.

TX Matrix Routing Matrix Hardware Configurations

•

Routing Matrix Configurations on page 58

•

Centralized Configuration on page 58

•

Distributed Configuration on page 59

Routing Matrix Configurations

A fully loaded routing matrix configuration consists of one TX Matrix router, four T640 routers, three to five 44-U, seismic-rated racks, 20 fiber-optic array cables, 10 Ethernet cables, and a cable management system. There are two types of configurations to consider when you plan and prepare forthe installation ofthe routingmatrix—centralized and distributed.

Centralized Configuration

In the centralized configuration, three racks are placed next to each other in a row. Figure 29 on page 59 and Figure 30 on page 59 show a rack view and a top view of a centralized configuration in which the left and center racks each hold two T640 routers, and the right rack holds the TX Matrix router. In Figure 30 on page 59, each connection to a T640 router represents five fiber-optic array cables.

NOTE: In the configuration shown in Figure 29 on page 59, if the raceway is

less than 1 m above the racks, 5-m fiber-optic array cables are usually long enough to connect the system.

In the centralized configuration, the total weight of the routing matrix and the heat it generates are concentrated in a relatively small area. You must ensure that your site can support the weight and your site cooling can adequately dissipate the heat. For physical and environmental specifications, see Table 31 on page 333 and Table 32 on page 335.

Page 91

Chapter 5: Preparing the Site for TX Matrix Router Installation

You can order the centralized configuration as a turnkey solution, or you can configure it from existing T640 routers.

Figure 29: Centralized Configuration—Rack View

Figure 30: Centralized Configuration

Distributed Configuration

In the distributed configuration, the placement of the racks is more flexible. Ensure that the rack placement allows you to connect the T640 routers to the TX Matrix router using the fiber-optic array cables. The maximum cable length is 100 m. The total weight and heat dissipation of the routing matrix are important in the distributed configuration, but not as critical as in the centralized configuration. For physical and environmental specifications, see Table 31 on page 333 and “TX Matrix Router Environmental Specifications” on page 335.

Page 92

TX Matrix Hardware Guide

Figure 31 on page 60 shows a top view of the distributed configuration. Each connection to a T640 router represents five fiber-optic array cables.

NOTE: If you plan to use 100-m fiber-optic array cables, contact your

customer support representative before you connect the T640 router and TX Matrix router.

Rack Mounting Considerations

If you are installing a TX Matrix router, or a T640 router that you intend to integrate into a routing matrix, consider these guidelines to facilitate the integration:

•

If you will be installing a fully configured centralized configuration, as described in “Centralized Configuration” on page 58 (one TX Matrix router and four T640 routers), plan to use a minimum of three racks side by side.

•

If you will be installing a fully configured distributed configuration, as described in “Distributed Configuration” on page 59 (one TX Matrix router and four T640 routers), plan to use one rack for the TX Matrix router, and two through four racks for the T640 routers (depending on whether you plan to install one or two T640 routers in a single rack).

Chapter 5: Preparing the Site for TX Matrix Router Installation

•

Rack Size and Strength

The TX Matrix router is designed for installation in a rack that complies with either of the following standards:

•

Account for the total weight of the routing matrix. One TX Matrix router and four maximally configured T640 routers weigh approximately 2755 lb (1250 kg).

If you are installing the T640 router in the bottom of an empty rack, reserve the top of the rack for the future installation of another T640 router.

We recommend that you install the TX Matrix router in its own dedicated rack. If you must install another device in the rack, consider the height and weight of the TX Matrix router and the fiber-optic array cable management above the chassis, including the optional cable shelf assembly.

A 600-mm rack as defined in the four-part Equipment Engineering (EE); European telecommunications standard for equipment practice (document numbers ETS 300 119-1 through 119-4) published bythe EuropeanTelecommunications Standards Institute (http://www.etsi.org). The horizontal spacing between the rails in a rack that complies with thisstandard isusually widerthan the TX Matrix router's mountingbrackets, which measure 19 in. (48.3 cm) from outer edge to outer edge. Use approved wing devices to narrow the opening between the rails as required.

TX Matrix Hardware Guide

The rack rails must be spaced widely enough to accommodate the TX Matrix chassis's externaldimensions: 44.5in. (113.0 cm)high, 31.4 in.(79.8 cm) deep,and 17.4 in.(44.2cm) wide. The outer edges of the mounting brackets extend the width to 19 in. (48.3 cm). The spacing ofrails and adjacent racks mustalso allow forthe clearances around the TX Matrix router and rack that are specified in “TX Matrix Clearance Requirements for Airflow and Hardware Maintenance” on page 63.

In an open-frame rack, center-mounting is preferable to front-mounting because the more even distribution of weight provides greater stability. If center-mounting is used, you use the mounting brackets attached to the center of the chassis for rack mounting; if front-mounting is used, you use the front-mounting flanges.

Before you mount the TX Matrix router in a four-post rack or cabinet, you must install the spacer bars on the rack. For instructions aboutinstalling the mounting hardware, see “Installing theTX Matrix Mounting Hardware for a Four-Post Rackor Cabinet”on page 75.

The chassis height of 44.5 in. (113.0 cm) is approximately 25.4 U. A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the ElectronicsIndustry Association. You can stack one TX Matrix router in a rack that has at least 25.4 U (44.5 in. or 113 cm) of usable vertical space.

The rack must be strong enough to support the weight of the fully configured TX Matrix router, up to about 495 lb (225 kg).

Spacing of Mounting Bracket and Flange Holes

There are two sets of holes in the mounting brackets and front-mount flanges used to attach the chassis to a rack. The holes within each set are spaced at 3 U (5.25 in. or

13.3 cm). The TX Matrix router can be mounted in any rack that provides holes spaced at those distances.

Connection to Building Structure

Always securethe rackto the structure of the building. If your geographical area is subject to earthquakes, bolt the rack to the floor. For maximum stability, also secure the rack to ceiling brackets. For moreinformation, see “Rack-MountingRequirementsand Warnings” on page 305.

TX Matrix Clearance Requirements for Airflow and Hardware Maintenance

When planning the installation site, allow sufficient clearance around the rack:

•

For the cooling system to function properly, the airflow around the chassis must be unrestricted. Figure 33 on page 64 depicts the airflow in the TX Matrix router.

•

For service personnel to remove and install hardware components, there must be adequate space at the front and back of the rack. Allow at least 30 in. (72.6 cm) in front of the rack and 24 in. (61.0 cm) behind the rack (see Figure 34 on page 64).

TX Matrix Fiber-Optic Array Cable Considerations

The fiber-optic array cables connect the switching planes of the T640 routers to the TX Matrix router by connecting the T640-SIBs to the TX-SIBs. When planning your installation site, consider the following fiber-optic array cable requirements:

•

You must use the same length for every fiber-optic array cable from a particular T640 router to the TX Matrix router. However, you do not need to use the same length for all fiber-optic array cables within a routing matrix. For example, if your routing matrix contains two T640 routers, you can use 6-meter fiber-optic array cables to one router and 100-meter fiber-optic array cables to the other router.

•

You must maintain a minimum bend radius of 2 in. (5.1 cm). We recommend that you maintain a bend radius of 10 in. (25.4 cm). If you must bend a fiber-optic array cable to a 2-inch radius, we recommend that you do not use more than two such bends.

•

Plastic wrap-ties can damage or crimp the fiber-optic array cables (see Figure 35 on page 65). We recommend that you use soft band straps to secure fiber-optic array cable.

Figure 35: Using Soft Band Straps to Secure Fiber-Optic Array Cables

•

The fiber-optic array cable connectors must fit through your site's cable conduits. For the connector dimensions, see Figure 37 on page 67.

In addition, consider the following when planning your installation site:

Page 98

TX Matrix Hardware Guide

•

Make sure any existing T640 routers are close enough to the location of the TX Matrix router, particularly in a distributed configuration. Consider the length of the longest fiber-optic array cables (100 meters), along with their routing through overhead raceways and mounting racks.

•

When you plug a fiber-optic array cable into a T640-SIB, the cable extends toward the left side of the T640 router (as viewed from the rear of the chassis) due to the horizontal orientation of the connectors (see Figure 36 on page 66). To facilitate the fiber-optic array cable routing, particularly in a centralized configuration, we recommend that you install the TX Matrix router to the right of the T640 routers (as viewed from the front of the chassis). This chassis placement might allow you to use shorter fiber-optic array cables—such as 4 m or 5 m—and helps you manage the bend radius of the cable. See “TX Matrix Routing Matrix Hardware Configurations” on page 58 for an illustration of the recommended centralized configuration.

Figure 36: T640-SIB

•

Plan the management of the fiber-optic array cables between the T640 routers and the TX Matrix router, keeping in mind the following considerations:

•

With four T640 routers, you can have atotal of 20 fiber-optic arraycables in a routing matrix.

NOTE: We recommend that you purchase one additional fiber-optic

array cable for each T640 router in the TX Matrix router in case one of the cables becomes damaged. Werecommend that you route the spare cables when you route the main cables, particularly in a distributed configuration.

•

The fiber-optic array cables must not interfere withTX Matrix routerand T640router airflow and maintenance access. For an illustration of the TX Matrix router airflow, see “TX Matrix Clearance Requirements for Airflow and Hardware Maintenance” on page 63.

•

The fiber-optic array cable weighs 0.22 lb (0.10 kg) per meter and each cable connector weighs 0.5 lb (0.23 kg).

•

With four T640 routers, you can have a total of 128 PICs in a routing matrix, and each PIC can contain up to 10 cables (for example, the 10-port Gigabit Ethernet PIC), for a total of 1,280 cables.Consider PICcabling aspart ofyour overall cable management
