Cisco CRS-1 Carrier Routing System

Tip The installation of a CRS-1 8-slot line card chassis may require space, floor loading, power, and cooling

modifications to a facility; therefore, you should plan the site well in advance of the scheduled delivery of the system.

The Cisco CRS-1 Carrier Routing System replaces much of the equipment in service provider points of presence (POPs) today. The routing systems are built around a scalable, distributed three-stage switch fabric and a variety of line card (packet) interfaces. These packet interfaces are located on modular services cards (MSCs) and their associated physical layer interface modules (PLIMs), which are effectively cross-connected to each other through the switch fabric.

CRS-1 8-slot line card chassis. This guide also describes site facilities

OL-5802-06

• The Cisco CRS-1 8-slot line card chassis is a half-height, rack-mounted version of the 16-slot

chassis. It is a highly scalable routing system that provides 640 gigabits per second (Gbps) of routing capacity and supports up to 8 MSCs. The chassis installs in a 19-inch equipment rack.

The Cisco CRS-1 8-slot line card chassis can be installed in colocation facilities, data centers, and many Tier II and Tier III locations. The routing system consists of a single rack-mounted chassis that contains the system components:

• Modular services cards (MSCs), also called line cards (up to eight)

• Physical layer interface modules, or PLIMs (up to eight, one for each MSC)

• Route processor (RP) cards (up to two)

• Switch fabric cards (four required)

• A chassis midplane that connects MSCs to their PLIMs and to switch fabric cards

The Cisco CRS-1 8-slot line card chassis has its own power and cooling subsystems.

The Cisco CRS-1 8-Slot Line Card Chassis

The Cisco CRS-1 8-slot line card chassis is the main component of the Cisco CRS-1. The chassis is a mechanical enclosure that contains a chassis midplane. The midplane holds the system modular services cards (MSCs), their associated physical layer interface modules (PLIMs), and switch fabric cards. The chassis is mounted in a 19-inch equipment rack. See the

page 4-3 for more information.

This section describes the main components of the Cisco CRS-1 8-slot line card chassis. It primarily identifies the components that are considered field-replaceable units (FRUs), but where additional detail is useful identifies subassemblies that are not field replaceable.

The following figures show the Cisco CRS-1 8-slot line card chassis from both the front (PLIM) and rear (MSC) sides.

Chassis Components

The Cisco CRS-1 8-slot line card chassis contains the following components:

• As many as eight modular services cards (MSCs), also called line cards, and eight physical layer

interface modules (PLIMs). The MSC and PLIM are an associated pair of cards that mate through the chassis midplane. The MSC provides the forwarding engine for Layer 3 routing of user data, and the PLIM provides the physical interface and connectors for the user data.

The MSC can be associated with several different PLIMs, which provide different interface speeds and technologies. The available PLIMs are as follows:

–

1-port OC-768c/STM-256c packet-over-SONET (POS). Available with short-reach (SR) optics.

122776

OL-5802-06

–

4-port OC-192c/STM-64c POS/DPT. Available with long-reach (LR), intermediate-reach (IR), short-reach (SR), and very-short-reach (VSR) optics.

–

OC-48c/STM-16c POS/DPT, configurable with 1 to 16 ports. Available with long-reach (LR) and short-reach

(SR) optics. This PLIM supports pluggable optics.

10-Gigabit Ethernet (GE. Available in long-reach (LR) optics. This PLIM supports pluggable optics, and can be configured with 1 to 8 ports.

–

Cisco CRS-1 SPA Interface Processor-800. Occupies one physical-layer-interface-module (PLIM) slot on the Cisco CRS-1 16- and 8-Slot Line Card Chassis. Supports six normal-height SPAs or three double-height SPAs or any combination in between.

• A chassis midplane. The midplane connects MSCs to their associated PLIMs and allows an MSC to

be removed from the chassis without having to disconnect the cables that are attached to the associated PLIM. The midplane distributes power, connects the MSCs to the switch fabric cards, and provides control plane interconnections. The midplane is not field replaceable by the customer.

• One or two route processor cards (RPs). The RPs provide the intelligence of the system by

functioning as the line card chassis system controller and providing route processing. Only one RP is required for system operation. For redundant operation, you can order a second, redundant RP as an option (CRS-8-RP/R). When two RPs are used, only one RP is active at a time. The second RP acts as a “standby” RP, serving as a backup if the active RP fails.

The RP also monitors system alarms and controls the system fans. LEDS on the front panel indicate active alarm conditions.

• Upper and lower fan trays. The fans pull cool air through the chassis. A removable air filter is

located below the PLIM card cage at the front of the chassis. Each fan tray contains three fans.

Chapter 1 Cisco CRS-1 Carrier Routing System

• Four half-height switch fabric cards. These cards provide the three-stage Benes switch fabric

(S1/S2/S3) for the routing system. The switch fabric performs the cross-connect function of the routing system, connecting every MSC (and its associated PLIM) with every other MSC (and its associated PLIM) in the system.

The switch fabric receives user data from one MSC and PLIM pair and performs the switching necessary to route the data to the appropriate egress MSC and PLIM pair. The switch fabric is divided into eight planes that evenly distribute the traffic across the switch fabric. Each switch fabric card implements two planes of the switch fabric.

• A power system that provides redundant power to the chassis. The power system consists of two

or DC power distribution units (PDUs) and two AC rectifier modules or two DC power entry modules (PEMs), one for each PDU. Each PDU supplies input power to a rectifier or PEM, which in turn provides processed power to the chassis. Each DC and AC power module contains a removable air filter, located on the back of the module.

The PLIM side of the chassis is considered the front of the chassis, where user data cables attach to the PLIMs and cool air enters the chassis. The MSC side, which is where warm air is exhausted, is considered the rear of the chassis.

Chassis Slot Numbers

The following figure shows the slot numbers on the front and back of the chassis.

As shown, the front (PLIM) side of the chassis has the following card slots:

• Eight PLIM slots (left to right: 0, 1, 2, 3...4, 5, 6, 7)

• Two route processor card slots (RP0 and RP1)

The rear (MSC) side of the chassis has the following card slots:

• Eight MSC slots (left to right: 7, 6, 5, 4...3, 2, 1, 0)

• Four half-height switch fabric card slots (SM0, SM1, SM2, and SM3)

Notice that the PLIM and MSC slot numbers are reversed. This reversal is because each MSC mates with its associated PLIM through the midplane. For example, the PLIM in slot 0 (far left on the chassis front) mates through the midplane with the MSC in slot 0 (far right on the chassis rear).

• Supplemental Bonding and Grounding

• Chassis Airflow

• Facility Cooling Requirements

CRS-1 Carrier Routing System 8-Slot

Chassis Power System

The 8-slot line card chassis can be either DC or AC powered. Each type of power system (DC or AC) provides power to chassis components. The chassis power system is made up of two input power distribution units (PDUs) and two power modules, one in each PDU. Each PDU is connected to a different power source. Input power enters the PDU and is passed to the power module, which provides 7,500 watts of power to the components in the chassis. Each power module has its own circuit breaker.

The Cisco CRS-1 8-slot line card chassis uses the AC power PDUs to provide the two types of AC wiring schemes (Wye and Delta). Each chassis has two PDUs, and each PDU takes one supply which, in the case of AC, has three internal zones such that two three-zone power supplies provide three redundant power zones (see the Cisco CRS-1 Carrier Routing System 8-Slot Line Card Chassis System Description for more information).

Because each PDU is connected to a separate and independent power source, the power system provides 2N power redundancy. During normal operation when both power sources are operational, both sets of PDUs and power modules function together to power the chassis. However, if a power sources fails, the other power source provides the other PDU and power module with enough input power to power the chassis. This 2N power redundancy enables the routing system to operate despite the power failure.

Chassis input power requirements are as follows:

• A DC-powered chassis requires 8,000 watts of DC input power.

OL-5802-06

Cisco CRS-1 Carrier Routing System 8-Slot Line Card Chassis Site Planning Guide

2-1

General Power and Grounding Requirements

• An AC-powered chassis requires 8,750 watts of AC input power.

Note These power requirements are for a fully loaded chassis with eight PLIMs. A chassis with six or

seven

PLIMs uses slightly less power. However, it is a good idea to allocate this much power for each

chassis to ensure that enough power is available for future system expansion.

See the Cisco CRS-1 Carrier Routing System 8-Slot Line Card Chassis System Description for detailed information about how each power system operates and distributes power to components in the chassis.

General Power and Grounding Requirements

This section describes the power and grounding requirements you must consider when planning the site facilities for the routing system. In addition, see the the “AC Power Requirements” section on page 2-6 for additional information about the power requirements for your chassis type.

“DC Power Requirements” section on page 2-3 or

Chapter 2 Power and Cooling

Note A qualified electrician should review the information in these sections to ensure that the installation site

meets these requirements. For larger system configurations, you may want to consult a facilities electrical expert to understand the load that the routing system may put on the facility power plant.

• Installation of the routing system must follow national and local electrical codes:

• In the United States: United States National Fire Protection Association (NFPA) 70 and United

States National Electrical Code (NEC).

• In Canada: Canadian Electrical Code, part I, CSA C22.1.

• In other countries: International Electrotechnical Commission (IEC) 60364, parts 1 through 7.

• Two separate and independent AC or DC power sources are needed to provide 2N redundancy for

system power. Each power source requires its own circuit breaker.

• Each power source must be providing clean power to the site. If necessary, install a power

conditioner.

• The site must provide short-circuit (over-current) protection for devices.

• Proper grounding is required at the site to ensure that equipment is not damaged by lightning and

power surges. In addition:

• For AC-powered systems, a grounding-type AC power outlet is required.

• For DC-powered systems, each DC PDU requires a connection to earth ground.

• When planning the power for the site, be sure to include the power requirements for any external

terminals and test equipment you will use with your system.

2-2

Note Be sure to review the safety warnings in Regulatory Compliance and Safety Information for the Cisco

CRS-1 Carrier Routing System before attempting to install the routing system.

Chapter 2 Power and Cooling

DC Power Requirements

A DC-powered line card chassis contains two DC-input power distribution units (PDUs) and two DC power entry modules (PEMs). Each DC PDU is connected to three DC power inputs and contains a single 7500-watt DC PEM that is field replaceable. Input DC power enters the PDU and is passed to the PEM, which provides power to the components in the chassis. Each PEM has its own circuit breaker.

In addition to the requirements described in the “General Power and Grounding Requirements” section

on page 2-2, DC input power requirements are as follows:

• A DC-powered chassis requires 8,000 watts of DC input power.

• Each DC PDU requires three VDC inputs of –48/–60 VDC (nominal). The PDU accepts input

power in the range –40.5 to –75 VDC.

• A DC-powered chassis requires access to the “A” and “B” power buses at the central office (CO).

This dual connectivity provides 2N power redundancy in case a power source fails.

–

One PDU should be connected to three –48/–60 VDC inputs from the central office “A” power bus.

–

The other PDU should be connected to three –48/–60 VDC inputs from the “B” power bus.

DC Power Requirements

• Required input current is as follows:

–

60 amps at nominal input voltage (–48/–60 VDC)

–

66 amps at low input voltage (–40.5 VDC).

• All power connection wiring must conform to the rules and regulations in the National Electrical

Code

(NEC) and any local codes. In addition, make sure that the wiring conforms to any internal

requirements at the installation site.

• Each DC power source must comply with the safety extra-low voltage (SELV) requirements in

60950-1, CSA-C22.2 No. 60950-1, EN60950-1, AS/NZS 60950, and IEC60950-1.

• A DC-powered system should be installed in a restricted access area in accordance with the

National

• All components in the area where DC input power is accessible must be properly insulated.

• A readily accessible two-pole disconnect device must be incorporated in the fixed wiring, unless it

is possible to rely on the identification of the power return conductor that is earth-grounded in the

DC power system.

DC Input Power and Ground Cables

Each PDU has three sets of double-stud terminals (RTN, –48V/–60V) for connecting DC input power. To

provide 2N power redundancy, one PDU should be connected to the central office “A” power bus

and the other PDU should be connected to the “B” power bus.

OL-5802-06

The requirements for the DC input power and ground connections are as follows:

• For DC input power cables, select the appropriate wire gauge based on the National Electrical

Code

(NEC) and local codes for 60-amp service at nominal DC input voltage (–48/–60 VDC).

Three

pairs of cable leads, source DC (–) and source DC return (+), are required for each PDU.

These

cables are available from any commercial cable vendor. All input power cables for the chassis

should have the same wire gauge and cable lengths should match within 10 percent of deviation.

Cisco CRS-1 Carrier Routing System 8-Slot Line Card Chassis Site Planning Guide

DC Power Requirements

Chapter 2 Power and Cooling

Each DC input power cable is terminated at the PDU by a cable lug. The cable lugs must be dual-hole, and have a 45-degree angle tongue. They must be able to fit over 1/4-inch terminal studs at 0.625-inch (15.88-mm) centers. For example, you could terminate a 2-AWG power cable with a cable lug, such as Panduit part number LCC2-14AWH-Q (Cisco part number 32-0677-01) or equivalent (see

Note To avoid hazardous conditions, all components in the area where DC input power is

accessible must be properly insulated. Therefore, before installing the DC cable lugs, be sure to insulate the lugs according to the manufacturer’s instructions.

Note DC input power cables must be connected to the PDU terminal studs in the proper positive

(+) and negative (–) polarity. In some cases, the DC cable leads are labeled, which is a relatively safe indication of the polarity. However, you must verify the polarity by measuring the voltage between the DC cable leads. When making the measurement, the positive (+) lead and the negative (–) lead must always match the (+) and (–) labels on the PDU.

• An earth ground cable is required for each DC PDU. We recommend that you use at least 6-AWG

multistrand copper wire. This wire is not available from Cisco Systems; it is available from any commercial cable vendor.

2-4

The ground wire cable lug should be dual-hole (as shown in Figure 2-2) and able to fit over M6 terminal studs at 0.625-inch (15.88-mm) centers (for example, Panduit part number LCD6-14A-L or

equivalent).

Note When wiring the PDU, be sure to attach the ground wire first (shown above on the far left side of PDU).

When removing the wiring, be sure to remove the ground wire last.

Note The power wire and ground wire connector screws have a 20 in.-lb torque value. The mounting screws

have a 9 in.-lb torque value.

The color coding of the DC input power cable leads depends on the color coding of the site DC power source. Typically, green or green and yellow indicates that the cable is a ground cable. Because there is no color code standard for the source DC wiring, you must ensure that the power cables are connected to the PDU terminal studs in the proper positive (+) and negative (–) polarity.

AC Power Requirements

Caution Although reverse polarity should not damage the DC power system, you should correct a reverse polarity

condition immediately.

AC Power Requirements

An AC-powered line card chassis contains two AC power distribution units (PDUs) and two AC rectifier modules. Each AC PDU is connected to an input AC power source and holds a single 7500-watt AC rectifier. Input AC power enters the PDU and is passed to the rectifier. Here, the input AC power is converted into the 54.5 VDC used to power components in the chassis. Each AC rectifier is field replaceable and has its own circuit breaker.

Two versions of the AC PDU are available to accommodate AC input power in either the Delta or Wye configuration. Each PDU has a different Cisco part number, and ships with an AC power cord that is 14

feet (4.3 m) long.

In addition to the requirements in the “General Power and Grounding Requirements” section on page 2-2, AC input power requirements are as follows:

Chapter 2 Power and Cooling

• An AC-powered chassis (Wye or Delta) requires 8,750 watts of AC input power.

• Two separate and independent AC power sources are required, one for each PDU. Each PDU should

be connected to a different power source to provide 2N power redundancy in case a power source fails.

• Each AC power source must provide 3-phase VAC power, and have its own circuit breaker.

• AC Delta input:

–

3-phase, 200 to 240 VAC (phase-to-phase), 50 to 60 Hz.

–

Input current: 30 A. The PDU is rated for 24-amp service, and accepts AC input of 30 A.

–

The Delta power cord has a 4-pin NEMA L15-30P plug (3 wire + protective earthing1 [3W+PE]). The

power cord is rated for 250 VAC, 30 A, and plugs into a similarly rated NEMA

L15-30R locking-type receptacle.

• AC Wye input:

–

3-phase, 200 to 240 VAC (phase-to-neutral), 50 to 60 Hz.

–

Input current: 16 A (International) or 20 A (North America). The PDU is rated for 14-amp service, and accepts AC input of 16 or 20

–

The Wye power cord has a 5-pin IEC 60309 plug (3 wire + neutral + protective earthing conductor (ground wire) [3W+N+PE]). The cord is rated for 400 VAC, 16 or 20 into a similarly rated IEC

phase-to-neutral voltage is approximately 120 VAC and 208 VAC phase to phase.

• AC Wye 3-phase wiring is typically used in Europe and countries where each phase-to-neutral

voltage is approximately 220 VAC.

AC Delta 3-Phase Wiring

Figure 2-6 shows a PDU wired for AC Delta 3-phase power. As shown, input AC power is routed to three

internal 2.5-kW power modules in the rectifier, where it is converted into DC power (nominal 54.5 VDC, 46 ADC) and routed to the three load zones of the chassis.

The AC Delta PDU is shipped with a 14-foot (4.3 m) AC power cord with a 4-pin L15-30P plug.

Supplemental Bonding and Grounding

The 8-slot line card chassis has a safety earth ground connection as part of the power cabling to the PDUs. The chassis also has supplemental bonding and grounding points (two threaded ground inserts) that you can use to connect the router to the central office ground system or interior equipment grounding system. Also referred to as the network equipment building system (NEBS) bonding and grounding stud, these grounding points are located at the rear (MSC side) of the chassis (see

Note The NEBS bonding and grounding points are intended to satisfy the Telcordia NEBS requirements for

supplemental bonding and grounding connections. If you are not installing the router in a NEBS environment, you can skip these guidelines and rely on the safety earth ground connection for the PDUs.

Figure 2-8 NEBS Bonding and Grounding Points (Rear of Chassis)

Supplemental Bonding and Grounding

Figure 2-8).

122792

1 NEBS bonding and grounding points

To connect the chassis to a supplemental ground connection, you must have the following:

• A grounding lug that has two M6 bolt holes with 0.625- to 0.75-inch (15.86- to 19.05-mm) spacing

between them, and a wire receptacle large enough to accept a 6-AWG or larger multistrand copper wire. The lug is not available from Cisco Systems; it is available from electrical-connector vendors.

• Two M6 or equivalent hex-head bolts with locking washers and nuts (nickel-plated brass is ideal).

These bolts, locking washers, and nuts are not available from Cisco Systems; they are available from any commercial hardware vendor.

• A grounding wire. Although we recommend at least 6-AWG multistrand copper wire, the actual

wire diameter and length depend on your router location and site environment. This wire is not available from Cisco Systems; it is available from any commercial cable vendor.

Caution The DC Return of the Cisco CRS-1 8-slot chassis should remain isolated from the system frame and

chassis (DC-I: Isolated DC Return).

OL-5802-06

Chassis Airflow

The Cisco CRS-1 8-slot line card chassis has two fan trays, with three fans each, that cool the chassis card cages. Cool air flows in at the bottom front of the chassis and flows through the chassis card cages and through the fans in the fan trays before being exhausted through the bottom rear of the chassis (see

Figure 2-9).

In addition, each AC or DC power module at the bottom of the chassis has self-contained fans that pull in cool air from the front of the chassis and exhaust warm air out the rear.

A replaceable air filter is located on the front of the chassis below the PLIM card cage. Each power module also has a replaceable air filter that attaches to the module at the front side of the chassis. How often you should replace the air filters depends on the facility environment.

In a dirty environment or when you start getting frequent temperature alarms, you should always check the intake grills for debris, and then check the air filters to see if they need to be replaced.

Note We recommend that you check the air filters once a month. Replace a filter when you notice a significant

amount of dust.

Facility Cooling Requirements

The 8-slot line card chassis dissipates considerable power that generates much heat. In large configurations, additional air cooling is required to maintain correct operating temperatures. The room air must be cooled by external cooling units that are installed as part of the routing system.

Site Planning Considerations

This chapter describes the general considerations to address while planning for the installation of the Cisco

CRS-1 8-Slot Line Card Chassis. It does not repeat the specifications in Chapter 3, but you should

keep those specifications in mind as you plan for your system.

This chapter includes the following sections:

• Basic Site and Installation Planning

• Tools Required for Installation

• Equipment Rack Considerations

• Aisle Spacing and Maintenance Access Floor Plan

• Power and Cooling Requirements

• System Console

• Cable Management

• Route Processor Cables

• PLIM Interface Cables

• Custom Cables

• Noise Control

• Cisco Installation Services

Basic Site and Installation Planning

As you plan for basic site and installation requirements, consider the following:

• Does the installation site have adequate power for the routing system?

• Can the routing system be positioned close to the AC or DC power source, and are the power

receptacles easy to reach?

• Does the site have appropriate equipment racks with space available in which to install the system?

Are additional equipment racks required? See the

page 3-2 for information about rack requirements.

• Is there a scissor lift or similar lifting device available to lift the chassis into the equipment rack?

In addition, make sure that the installation site meets the following access requirements:

“Equipment Rack Specifications” section on

OL-5802-06

Cisco CRS-1 Carrier Routing System 8-Slot Line Card Chassis Site Planning Guide

Tools Required for Installation

• At least 48 inches (122 cm) of clearance exists between rows of equipment racks. This space is

needed to access components in the chassis. Additional clearance may be necessary for installation.

• Enough room exists for the system console terminal, and that the console cable is long enough to

reach the routing system from the terminal.

• Fan tray exhaust vents are not blocked, and airflow at the bottom of the chassis is not blocked.

When planning the site, you should think about potential expansion of the system. Consider the following:

• Equipment rack space for additional chassis

• Power and cooling requirements for additional chassis

• Cable management for routing system cables

Tools Required for Installation

The following tools are required to install the Cisco CRS-1 8-Slot Line Card Chassis:

• Safety hand truck, pallet jack, or forklift to move the equipment to the installation site. Make sure

that the device is capable of preventing the router from tipping. For example, you could use a safety hand truck with retractable safety leg wheels and a security strap, such as the Stevens Appliance Truck Company “Escort,” Model STEV SRT-M-66 (distributed by McMaster-Carr as Model 2654T6) or an equivalent safety hand truck.

Chapter 4 Site Planning Considerations

Aisle Spacing and Maintenance Access Floor Plan

Note We recommend that you use a scissor lift or similar lifting device to position the chassis in the rack and

to hold the chassis in place while you bolt it to the rack. A forklift is not recommended for this purpose.

As you plan the installation of the chassis into the equipment rack, consider the following:

• Make sure that the floor mounting bolts on the equipment rack are accessible, especially if annual

retorquing of bolts is required.

• For chassis installation, you must have access to the vertical mounting rails at each corner of the

equipment rack.

• Consider whether the area around the rack is large enough to accommodate the scissor lift (or similar

lifting device) and installation personnel.

• A minimum of 48 mounting screws (provided with the chassis) are needed to secure the chassis to

the rack. To secure the chassis to the rack, you install 12 screws in each of the four corners of the rack.

• The rack should have horizontal shelf brackets to place the chassis on. The brackets must be able to

support at least 650 lb. (294.8 kg). If the rack does not have horizontal mounting rails, a set of rails is included in the installation kit, which is available as an option (CRS-8-INSTALL-KT=).

Chapter 4 Site Planning Considerations

Caution Standard rack-mounting screws are not strong enough to secure the chassis to the equipment rack.

Use

only those mounting screws that are shipped with the chassis or those listed in the “Equipment Rack

Specifications” section on page 3-2.

For complete instructions on mounting and securing the chassis to a rack, see the Cisco CRS-1 Carrier Routing System 8-Slot Line Card Unpacking, Moving, and Securing Guide.

Aisle Spacing and Maintenance Access Floor Plan

The floor plan for the Cisco CRS-1 must include enough space to install the 8-slot line card chassis in the equipment rack and allow sufficient airflow for the system. The floor plan must also provide enough room to access chassis components for maintenance (for example, to remove fan trays, power modules, cables, and air filters).

Figure 4-2 shows a top view of the Cisco CRS-1 8-slot line card chassis footprint required for installation

(with optional front and rear cosmetics installed).

Note For chassis installation, make sure that enough room exists in front of the chassis to accommodate

installation personnel and the scissor lift (or similar lifting device) used to hold the chassis in the rack while it is bolted in.

Dimensions of the 8-Slot Line Card Chassis

The dimensions for the Cisco CRS-1 8-slot line card chassis are:

• Chassis depth (including closed (optional) front and rear doors and an installed cable management

bracket): ~35 to 40 in. (88.9 to 101.6 cm)

• Chassis height: 38.5 in. (97.8 cm)

• Chassis width: 17.5 in. (44.5 cm).

Note Because there is no external switch-fabric interconnection cabling on a single line card chassis system,

the rear door is optional.

Front and Rear Clearances

The site requires the following front and rear clearances for chassis installation and maintenance access:

• To install the chassis in the equipment rack: 40.4 inches (102.6 cm)

• To service components and allow system airflow (both in front of and behind the chassis): 36 inches

(91.4 cm)

Note Maintain at least 6 inches (15.2 cm) of clearance at both the inlet and exhaust openings on the

chassis and on the power modules to allow sufficient airflow.

Power and Cooling Requirements

See Chapter 2, “Power and Cooling,” for information about the power and cooling systems on the 8-slot chassis and for information about the power and cooling requirements at the installation site.

System Console

A system console is required to configure the routing system for operation. As you plan your site facilities, make sure that the site has enough room for a system console and the console cable is long enough to reach the routing system.

Note The console port does not support modem control or hardware flow control. The port

requires a straight-through EIA/TIA-232 cable.

Cable Management

Chapter 4 Site Planning Considerations

As the size of the routing system increases, the cabling required for the chassis increases. For example, a fully loaded 8-slot line card chassis has more cables connected to it than a partially loaded chassis. The cabling runs must be carefully planned. The basic configurations for various routing systems should be arranged to minimize the complexity and length of the cable runs. Precut and terminated cables are considered part of the basic configuration.

• CONSOLE or AUX RJ-45 RS-232 serial ports on the route processor cards for terminal connections

• Ethernet ports on the route processor cards for connecting network management equipment

• Modular service cards (MSCs) and physical layer interface modules (PLIMs) for data connections

The cable-management bracket is for organizing these interface cables to keep the front of the chassis clear and to eliminate sharp bends in the cables.

Caution Excessive bending can damage interface cables.

The cable-management bracket has a special telescoping feature that allows the bracket to be extended when the chassis is upgraded with higher-density cards. This extension feature also helps in installing the cables in the chassis.

Figure 4-3 shows the chassis cable-management bracket.

Ta b l e 4-1 Route Processor Cables

RP Port Required Cable Type

Ethernet management Shielded twisted-pair (STP) cable (Category 5 or better). Required

Alarm Shielded cable. Required for EMC compliance.

PLIM Interface Cables

You must provide the PLIM interface cables. Because the type and number of interfaces can vary, plan these cable runs prior to the installation. When planning the cable runs, consider the following:

• Number and type of interface connections (OC-48/STM-16, OC-192/STM-64, OC-768/STM-256,

and 10-Gigabit Ethernet)

• Termination at the other end of the cables (such as patch panel or optical transport equipment)

• Proper length and termination of cables

for enhanced immunity to external electromagnetic disturbance levels of 10 V/m and 10 Vrms.

Custom Cables

OL-5802-06

The installation site may require custom cables designed for the facilities. Cisco can assist you in planning custom cables.

Noise Control

A routing system can generate large amounts of fan noise. The 8-slot line card chassis has some built-in noise reduction, such as fan speed control. If the routing system is installed in an environment where excessive noise could be harmful to personnel, some other noise reduction options could be attempted. Passive noise reduction could include the installation of foam panels to insulate the surrounding area from the noise.

Additional noise-reduction measures have to be designed on an individual site basis.

Cisco Installation Services

Cisco or a Cisco partner can provide a complete installation, from planning to power up. For information about Cisco or Cisco partner installation services, consult Cisco Customer Advocacy.

System Testing, Certification, and Warranties

Chapter 4 Site Planning Considerations

After the routing system has been installed, it must be tested and certified. Consult Cisco Customer Advocacy for information about testing, certification, and warranties.
