Chassis Overview

The Cisco CRS 4-slot routing system can be installed in locations where the 16-slot or 8-slot systems may not fit (for example, 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 following system components:

• Switch fabric cards (SFCs) (up to four)

• Route processor (RP) cards (up to two) or performance route processor (PRP) cards (up to two)

• Up to four modular services cards (MSCs), forwarding processor (FP) cards, or label switch

processor (LSP) cards (also called line cards)

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

• A chassis midplane that connects line cards to their associated PLIMs and to the SFCs

The Cisco CRS 4-slot line card chassis has its own power and cooling subsystems. The power shelf (AC or DC as ordered) is pre-installed in the chassis when you receive the routing system.

The Cisco CRS 4-slot line card chassis contains the following components:

• As many as four MSCs, FPs, or LSPs and four PLIMs. The line card and PLIM are an associated

pair of cards that mate through the chassis midplane. The line card provides the forwarding engine for Layer 3 routing of user data, and the PLIM provides the physical interface and connectors for the user data.

Each line card can be associated with several different PLIMs that provide different interface speeds and technologies. For a full list of available PLIMs, please contact your Cisco sales representative.

Chassis Components

Chapter 1 Overview

• A chassis midplane that connects line cards to their associated PLIMs. The midplane design allows

a line card 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 line cards 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 function as the Cisco CRS 4-slot line card chassis

system controller and provide route processing.

Only one RP is required for system operation. For redundant operation, you can order a second RP as an option (CRS-4-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.

A Performance Route Processor (PRP) is also available for the Cisco CRS 8-slot line card chassis. Two PRPs perform the same functions as RPs, but provide enhanced performance for both route processing and system controller functionality.

Note A chassis may not be populated with a mix of RP and PRP cards. Both route processor cards

should be of the same type (RP or PRP).

• Fan tray. 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. The fan tray has four fans that provide n+1 redundancy.

• Four switch fabric cards (SFCs). These cards provide the three-stage Benes switch fabric for the

routing system. The switch fabric performs the cross-connect function of the routing system, connecting every line card (and its associated PLIM) with every other line card (and its associated PLIM) in the system.

The switch fabric receives user data from one line card and PLIM pair and performs the switching necessary to route the data to the appropriate egress line card and PLIM pair. The switch fabric is divided into eight logical planes (four physical planes) that are used to 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 an AC

power shelf, which contains four AC rectifier modules, or a DC power shelf, which encloses four DC power supplies. The power shelf (AC or DC as ordered) is pre-installed in the chassis when you receive the routing system.

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 switch fabric card side, which is where warm air is exhausted, is considered to be the rear of the chassis.

Chassis Cable Management

The Cisco CRS 4-slot line card chassis has cable management features for the front (PLIM) side of the chassis, just above the card cage. The horizontal cable management trays have a special telescoping feature that allows them to be extended when the chassis is upgraded with higher-density cards. This extension also helps when installing the cables in the chassis.

Figure 1-5 shows the cable management bracket for the chassis.

Figure 1-5 Cable Management Bracket

Chassis Cable Management

Chassis Cooling System

The Cisco CRS 4-slot line card chassis has a single fan tray containing four fans that cool the chassis card cage. Cool air flows in at the bottom front of the chassis and flows through the chassis card cage and through the fans in the fan tray before being expelled through the top rear of the chassis (see

Figure 1-6).

In addition, each 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. Air also flows under the midplane, through the SFCs, and then the fans to be expelled. There are these two parallel paths for air flow.

A replaceable air filter is located inside the chassis below the PLIM card cage at an angle. In addition, there is a removable air filter on the front of the power tray air intake grille on the front (PLIM) side of the chassis.

How often the air filters should be replaced depends on the facility environment. In a dirty environment, or when you start getting frequent temperature alarms, you should always check the intake grille 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.

Preventing Electrostatic Discharge

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. We recommend to use an ESD-preventive strap whenever you handle network equipment or one of its components.

Following are guidelines for preventing ESD damage:

• Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.

Connect the equipment end of the connection cord to an ESD connection socket on the router or to a bare metal surface on the chassis.

• Handle a card by its ejector levers, when applicable, or the card’s metal carrier only; avoid touching

the board or connector pins.

• Place a removed card board-side-up on an antistatic surface or in a static-shielding bag. If you plan

to return the component to the factory, immediately place it in a static-shielding bag.

• Avoid contact between the card and clothing. The wrist strap protects the board only from ESD

voltage on the body; ESD voltage on clothing can still cause damage.

Basic Chassis Power Recommendations

The Cisco CRS Carrier Routing System 4-Slot Line Card Chassis can be configured with either an AC-input power subsystem or a DC-input power subsystem. Site power requirements differ depending on the source voltage used. Follow these precautions and recommendations when planning power connections to the router:

• Check the power at your site before installation and periodically after installation to ensure that you

are receiving clean power. Install a power conditioner, if necessary.

• Install proper grounding to avoid damage from lightning and power surges.

About Installing and Removing the Power Components

Caution A Cisco router must be operated with all its power modules installed at all times for electromagnetic

compatibility (EMC).

The Cisco CRS 4-slot line card chassis requires that at least the power shelves and their components be installed to operate properly. Two types of power shelves exist: an AC shelf and a DC shelf. An AC power shelf houses AC rectifiers, while a DC power shelf houses the DC power input module (PIM) and DC power input shelf (which encloses the DC power supplies). We recommend that you use only one type of power shelf in a chassis at a time.

Chapter 2 Installing and Removing Power Components

Warning

This unit might have more than one power supply connection. All connections must be removed to de-energize the unit.

Statement 1028

The Cisco CRS 4-slot line card chassis is shipped fully populated with a power shelf that contains four power supplies for power redundancy. See the appropriate installation section (see “Installing a DC

Power Shelf” section on page 2-14 or “Installing an AC Power Shelf” section on page 2-24) for detailed

installation information.

As viewed from the front (PLIM) side of the chassis, the left two power supplies feed output A, while the right two power supplies feed output B.

For 2N redundancy, the power input on rear (SFC) side of the chassis should be from two different branch sources, with the left two input connections to one branch source and the right two to the other branch source. With this configuration the router remains fully powered in case one branch source fails. In normal operation all power supplies should be installed.

Be sure to install the power shelf before installing the power supplies.

Caution If you install a non-Cisco power supply in the chassis, upon its detection as a non-compliant power

supply, the system will shut down. Using non-Cisco power supplies MAY RESULT IN COMPLETE CHASSIS SHUTDOWN due to insufficient power.

Supplemental Unit Bonding and Grounding Guidelines

Although the router chassis has a safety earth ground connection as part of the power cabling to the power shelf, the chassis includes an option that allows you to connect the central office ground system or interior equipment ground system to the supplemental bonding and grounding receptacles on the router chassis. Two ground studs are located on the rear (SFC) side of the chassis. (see Figure 2-1). This ground point is also called the network equipment building system (NEBS) bonding and grounding stud.

Note These bonding and grounding receptacles satisfy the Telcordia® NEBS requirements for supplemental

bonding and grounding connections. If you are not installing the router in a NEBS environment, you can choose to bypass these guidelines and rely on the safety earth ground connection for the power shelf.

If you plan to connect the Cisco CRS 4-slot line card chassis system to a network equipment building system (NEBS)-compliant supplemental bonding and grounding system at the site, you must have the following:

• A minimum of one ground lug that has two M6 bolt holes with 0.625-inch (15.86-mm) spacing

between them, and a wire receptacle large enough to accept a 6-AWG or larger multistrand copper wire. The lug is similar to the type used for the DC-input power supply leads. This ground lug is not available from Cisco Systems. This type of lug is available from electrical-connector vendors, such as Panduit.

• Two M6 nuts with locking washers (nickel-plated brass is ideal). This hardware is not available

from Cisco Systems; they are available from any commercial hardware vendor.

• A commensurately rated ground 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.

Powering the Chassis Up or Down

The chassis does not have a single enable switch that powers the entire chassis and all its components up and down. (These switches are called enable switches because they enable the power supplies to produce output voltage and power). Most components on the chassis, such as the power supplies, MSCs, FPs, PLIMs, and fan trays can be removed or installed in the chassis while it is running.

Before you can power the chassis up, you must complete the following tasks:

Chapter 2 Installing and Removing Power Components

Step 1 Install the appropriate power shelf for your system (see the “Installing a DC Power Shelf” section on

page 2-14 or the “Installing an AC Power Shelf” section on page 2-24).

Step 2 Install the power supplies (see the “Installing a Power Supply” section on page 2-28).

Step 3 Install the route processor (RP) card (see the “Installing an RP or PRP Card” section on page 4-26).

Step 4 Install the input power cables to the input power connectors on the rear of the chassis, and the other end

(plug side) to the AC or DC power source.

Step 5 Activate your power source.

Step 6 Turn the two power shelf enable switches on the rear (SFC) side of the power shelf (see Figure 2-7) to

the ON position.

Note The two enable switches on the rear (SFC) side of the AC power shelf (Figure 2-7) put the chassis in

standby mode; in other words, they only power down the -54VDC output from the power supplies.
