Statement 1071

Cisco CRS Carrier Routing System

This chapter describes the Cisco CRS 8-slot LCC and its main components, and provides an overview of the installation process. It contains the following sections:

• The Cisco CRS 8-Slot Line Card Chassis, page 1-2

• Overview of Site Planning Steps, page 1-11

Note The installation of a CRS 8-slot LCC 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 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) or forwarding processors (FP) and their associated physical layer interface modules (PLIMs), which are effectively cross-connected to each other through the switch fabric.

The Cisco CRS 8-slot LCC is a half-height, rack-mounted 8-slot version of the 16-slot chassis. It is a highly scalable routing system that provides 2.24 terabits per second (Tbps) of routing capacity and supports up to 8 MSCs or FPs. (A terabit is 1 x 10 19-inch equipment rack.

The Cisco CRS 8-slot LCC 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) or forwarding processors (FP), also called line cards (up to eight)

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

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

• Switch fabric cards (SFCs) (four required)

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

The Cisco CRS 8-slot LCC has its own power and cooling subsystems. Two types of power systems are available: fixed or modular configuration. Both power configurations use either AC or DC power.

The Cisco CRS 8-slot line card chassis supports both 40 G and 140 G fabric cards and line cards. The Cisco CRS-1 Carrier Routing System uses fabric cards designed for 40 GB operation (FC/S cards) and the Cisco CRS-3 Carrier Routing System uses fabric cards designed for 140 GB operation (FC-140/S cards).

Caution A router with a mixture of 40 G and 140 G fabric cards is not a supported mode of operation. Such a

mode is allowed temporarily only during the upgrade process.

Note Throughout this document, the term Cisco CRS Carrier Routing system refers to both the Cisco CRS-1

Carrier Routing System and the Cisco CRS-3 Carrier Routing System, unless otherwise specified.

The Cisco CRS 8-Slot Line Card Chassis

The Cisco CRS 8-slot line card chassis is the main component of the Cisco CRS. The chassis is a mechanical enclosure that contains a chassis midplane. The midplane holds the system modular services cards (MSCs) and forwarding processor (FP) cards, their associated physical layer interface modules (PLIMs), and switch fabric cards (SFCs). The Cisco CRS 8-slot line card chassis contains its own power system; either fixed or modular configuration. See the “Chassis Power System” section on page 2-1 for more information. The chassis is mounted in a 19-inch equipment rack. See the “Equipment Rack

Considerations” section on page 4-3 for more information.

Chapter 1 Cisco CRS Carrier Routing System

This section describes the main components of the Cisco CRS 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.

Chassis Components

OL-5802-09

The Cisco CRS 8-slot LCC contains the following components:

• As many as eight modular services cards (MSCs) or forwarding processor (FP) cards (both types are

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

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

1-7

The Cisco CRS 8-Slot Line Card Chassis

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

–

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

–

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 PLIMs (available with a variety of optics, including LR). These PLIMs support pluggable XENPAK and XFP optics, and can be configured with up to 20 ports, depending on the PLIM.

–

100-Gigabit Ethernet PLIM. This single-port PLIM supports a pluggable CFP optics module.

–

Cisco CRS SPA Interface Processor-800. Occupies one PLIM slot on the Cisco CRS 16- and 8-Slot LCC. Supports six normal-height SPAs or three double-height SPAs or any combination in between.

• 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.

Chapter 1 Cisco CRS Carrier Routing System

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

functioning as the LCC 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.

A Performance Route Processor (PRP) is also available for the Cisco CRS 8-slot line card chassis. Two PRPs perform the same functions as two 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).

• 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 four fans.

• Four half-height switch fabric cards (SFCs). 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 (or FP) and PLIM pair and performs the switching necessary to route the data to the appropriate egress MSC (or FP) 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.

1-8

• A power system that provides redundant power to the chassis. Two types of power systems are

available: fixed configuration power and modular configuration power. Both power configurations use either AC or DC power. The fixed configuration power solution contains two power distribution units (PDUs), with either one AC rectifier or one DC power entry modules (PEM) per PDU. Each

DC PEM and AC rectifier contains a removable air filter, located on the back of the module. The modular configuration power solution contains two power shelves with either up to four DC power modules (PMs) or up to three AC PMs per power shelf.

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

This section identifies the location and slot numbers for major cards and modules (primarily the field-replaceable units) that plug into the chassis.

Figure 1-6 shows the slot numbers on the front (PLIM) side of the Cisco CRS 8-slot line card chassis.

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

The MSC slot numbers are reversed from the PLIM slot numbers on the other side of the chassis. Because an MSC mates with its associated PLIM through the midplane, MSC slot 0 is on the far right side of the chassis looking at it from the rear (MSC) side.

PLIM slot 0 is on the far left side of the chassis, looking at if from the front (PLIM) side. MSC slot 0 and PLIM slot 0 mate with each other through the midplane, and so do all other MSC and PLIM slots (0 through 7).

CHAPTER

Power and Cooling

This chapter describes the Cisco CRS Carrier Routing System 8-Slot LCC power and cooling systems. It also provides the power, grounding, and cooling requirements for the installation site to help you plan the site facilities for the system. Cisco CRS Carrier Routing System 8-Slot Line Card Chassis System Description provides detailed information about these components.

This chapter contains the following sections:

• Chassis Power System, page 2-1

• General Power and Grounding Requirements, page 2-2

• Bonding and Grounding Guidelines, page 2-3

• DC Power Systems, page 2-5

• AC Power Systems, page 2-11

• Chassis Airflow, page 2-19

• Facility Cooling Requirements, page 2-20

Chassis Power System

The 8-slot LCC can be either DC or AC powered. Each type of power system (DC or AC) provides power to chassis components. There are two options for power systems: the fixed configuration power system and the modular configuration power system.

• Fixed configuration power system consists of two power distribution units (PDUs) and either DC

power entry modules (PEMs) or AC rectifiers. The AC version requires 3-phase AC-Delta or AC-Wye input power to the PDU. The PDU distributes facility power to the AC rectifier or DC PEM, which in turn provides processed power to the chassis. A removable air filter is located on the front of each DC PEM and AC rectifier. The fixed configuration power system includes SNMP MIBS and XML support.

• Modular configuration power system consists of two power shelves and either AC or DC power

modules (PMs). However, unlike the fixed configuration power system, the AC version of the modular configuration power system requires single-phase AC input power to power the shelves. If you have 3-phase AC-Delta or AC-Wye at your equipment, a Cisco CRS 3-Phase AC PDU will be required to convert 3-phase AC input power to single-phase AC input power for the power shelf. At the shelf level, the power system provides 2N redundancy; the PMs themselves provide load-share redundancy. The modular configuration power system also includes SNMP MIBs and XML support.
