AC and DC Power Subsystems

A router ships as either an AC or DC powered system. Source power connects to power distribution units (PDUs) on the back of the chassis which route power to the power supplies, also referred to as power entry modules (PEMs).

Caution To ensure that the chassis configuration complies with the required power

budgets, use the on-line power calculator. Failure to properly verify the configuration may result in an unpredictable state if one of the power units fails. Contact your local sales representative for assistance.

AC Power Entry Modules

An AC powered router consists of two AC PDUs and AC PEMs. AC power to the router is provided through power cords connected from AC power outlets to the PDUs on the chassis rear panel as shown in

Switch Fabric and Alarm Card Overview

The switch fabric provides synchronized gigabit-speed connections between line cards and the route processor. The 9-slot switch fabric and alarm card cage contain:

• 2 clock scheduler cards (CSCs)

• 5 switch fabric cards (SFCs)

• 2 alarm cards

Note The two alarm cards that are located in the switch fabric and alarm card

cage are not part of the switch fabric.

One CSC and four SFCs are required for an active switch fabric; the second CSC and the fifth SFC provide redundancy. The combination of CSCs and SFCs make up the 10-Gbps per-slot switch fabric.

Each SFC or CSC provides a 10-Gbps full-duplex connection to each line card in the system. For example, in a Cisco XR 12410 router with 8 line cards, each with 2 x 10

Gbps capacity (full duplex), the system switching bandwidth is 8 x 20 Gbps

= 160 Gbps.

OL-13832-01

Figure 1-2 shows the slot configuration in the switch fabric and alarm card cage.

The labeling identifies the type of card for each slot and can only be seen when the air filter door is opened.

Note Cisco XR 12410 router support online insertion and removal (OIR), which allows

you to remove and replace a card while the router remains powered on.

Cisco XR 12410 Router Installation Guide

Switch Fabric and Alarm Card Overview

Switch Fabric Card Functionality

Routers ship from the factory with 2 CSCs and 5 SFCs installed in the 7 slots in the switch fabric and alarm card cage (see

• CSCs are installed in slot 0 (CSC0) or slot 1 (CSC1).

• SFCs are installed in slot 2 (SFC0), slot 3 (SFC1), slot 4 (SFC2),

slot

5 (SFC3), and slot 6 (SFC4).

Note The enhanced version of the CSC and SFC cards is required for support of BITS,

Single Router APS and Dual Priority features. The enhanced version of the cards cannot be mixed with the original version fabric cards.

Clock Scheduler Card

Clock scheduler cards provide the following functionality:

• Scheduler—Handles all scheduling requests from the line cards for access to

the switch fabric.

Chapter 1 Cisco XR 12410 Router Overview

Figure 1-2).

1-10

• System clock—Supplies the synchronizing signal to all SFCs, line cards, and

the RP. The system clock synchronizes data transfers between line cards or between line cards and the RP through the switch fabric.

• Switch fabric—Carries user traffic between line cards or between the RP and

a line card. The switch fabric on the CSC is identical to the switch fabric on the SFC.

The second CSC provides redundancy for the data path, scheduler, and reference clock. Traffic between the line cards and the switch fabric is monitored constantly. If the system detects a loss of synchronization (LOS), it automatically activates the data paths on the redundant CSC so data flows across the redundant paths. The switch to the redundant CSC occurs within sub-seconds (the actual switch time depends on your configuration and its scale).

Cisco XR 12410 Router Installation Guide

OL-13832-01

Chapter 1 Cisco XR 12410 Router Overview

Switch Fabric Card

The switch fabric cards augment the traffic capacity of the router. SFCs contain switch fabric circuitry that can only carry user traffic between line cards or between the RP and the line cards. SFCs receive all scheduling information and the system clock signal from the CSCs.

Alarm Cards and Alarm Display

The two alarm cards (in the switch fabric and alarm card cage) provide several functions:

• Supply +5 VDC to the MBus modules on router components (see AC and DC

Power Subsystems, page 1-5).

• Work in conjunction with the alarm display to monitor the system. The alarm

display (sometimes referred to as the alarm display card) is above the horizontal cable management bracket (

Line Card and Route Processor Overview

The line card and route processor (RP) card cage has 10 user-configurable slots that support a combination of line cards and either one or two RPs (see

Figure 1-2). Router configurations can consist of either nine line cards and one

RP, or eight line cards and two RPs (one primary and one redundant) using the following slot configurations:

• Slots 0 to 7 accommodate the newer (wider) line card designs. These wider

line card slots can also accept narrower legacy line cards.

• Slots 8 and 9 only accept RPs or a narrower legacy line card.

Note If a system uses only one RP install it in slot 9. You can use slot 8 for a

legacy line card.

Cisco XR 12410 Router Installation Guide

OL-13832-01

Line Card and Route Processor Overview

Line Cards

Ports and connectors on the line card front panels provide interfaces for external connections. Line cards communicate with the RP and exchange packet data with each other through the switch fabric cards.

Caution Any unoccupied card slot in the line card and RP card cage must have a blank

filler panel installed to meet electromagnetic compatibility (EMC) requirements and to ensure proper air flow through the chassis. Also, if the front panel of a line card does not completely fill the card slot opening, a narrow card filler panel must be installed to meet the EMC requirements.

A cable management bracket on the front panel of each line card helps to organize the interface cables connected to that line card.

The following line cards, SIPs, and SPAs are supported on the Cisco XR 12410 router:

Chapter 1 Cisco XR 12410 Router Overview

The PRP-2 performs the following primary functions:

• Executes routing protocol stacks

• Performs all protocol communications with other routers

• Builds and distributes forwarding information to all line cards

• Uploads the operating system software images to all installed line cards

during power-up

• Provides out-of-band system console and auxiliary ports and an Ethernet port

for router configuration and maintenance

• Monitors and manages the power and temperature of system components

such as line cards, power supplies, and fans

The Cisco PRP-2 delivers all these functions with enhanced performance and capabilities. It also delivers the following feature enhancements (depending on the software version running):

• Gigabit Ethernet management port

• Hard-drive support (optional part)

• BITS input ports

• 1 GB compact image Flash memory support (optional part)

• Memory scalability up to 4 GB

The PRP-2 communicates with the line cards either through the switch fabric or through the MBus. The switch fabric connection is the main data path for routing table distribution as well as for packets that are sent between the line cards and the PRP-2. The MBus connection allows the PRP-2 to download a system bootstrap image, collect or load diagnostic information, and perform general, internal system maintenance operations.

The PRP-2 can be designated as either the Designated System Controller (DSC) or the Secure Domain router (SDR).

The Designated System Controller (DSC) performs the following functions:

• Implements control plane operations for the chassis

• Monitors temperature and voltage

• Monitors line cards

• On boot up, the first card to become active is designated as the DSC.

PRP PCMCIA Card Slots and Status LEDs

Two PCMCIA card slots (slot 0 and slot 1) provide the PRP with additional flash memory capacity. All combinations of different flash devices are supported by the PRP. You can use ATA flash disks, Type 1 or Type 2 linear flash memory cards, or a combination of the two.

Note The PRP only supports +5.2 VDC flash memory devices. It does not support

+3.3 VDC PCMCIA devices.

Status LEDs (Slot-0 / Slot-1) indicate when the flash memory card in that slot is accessed (see to remove a flash card from the slot.

Figure 1-9). Each slot has an eject button (located behind the cover)
