THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT
NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT
ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR
THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION
PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO
LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class
A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate
radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television
reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in
part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation.
However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class
A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct
any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco
equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by
using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television
or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Chapter 1 Product Overview

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

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 and Cisco XR 12810 Routers with
8 line cards, each with 2 x 10
bandwidth is 8 x 20 Gbps = 160 Gbps.

Gbps capacity (full duplex), the system switching

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 and Cisco XR 12810 Routers support online insertion and

removal (OIR), which allows you to remove and replace a card while the router
remains powered on.

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 Product 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).

Chapter 1 Product 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.

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
and Cisco XR 12810 Routers:

Chapter 1 Product Overview

–

The Cisco XR 12410 and Cisco XR 12810 Routers supports online
insertion and removal (OIR), allowing you to remove and replace a card
while the router remains powered on.

Note Refer to the current s software release notes for the most up-to-date list of

supported line cards (see

Request” section on page -xiv).

Route Processor

The route processor for the Cisco XR 12410 and Cisco XR 12810 Routers is the
Performance Route Processor-2 (PRP-2) and the Performance Route Processor-3

• Memory scalability up to 4 GB with PRP-2 and up to 8 GB with PRP-3.

The PRP-2 and PRP-3 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. The MBus connection allows the PRP-2 and PRP-3 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
