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

Chapter 1 Product 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

OL-17441-01

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 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).

OL-17441-01

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:

PRP-3 is the route processor for the Cisco XR 12404 and 12804 Router chassis running Cisco IOS XR Software Release 3.8.0 or a later release. The PRP-3 is available as product number PRP-3 or PRP-3= for a primary route processor and is available as PRP-3/R for a redundant route processor. PRP-3 has significant improvements over PRP-2. These improvements include increased speed, improved scalability, higher system memory, faster packet processing. Because PRP-3 does not support Cisco IOS, the bootflash memory no longer exists in PRP-3. PRP-3 ROMMON has software intelligence to download a Cisco IOS XR image without the support of bootflash memory.

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)

Chapter 1 Product Overview

Note PRP-3 does not have PCMCIA slots (slot 0 and slot 1). PRP-3 has an external

CompactFlash (disk0:) that replaces the PCMCIA slots.

PRP Ethernet Ports and Status LEDs

The PRP has two 8-pin media-dependent interface (MDI) RJ-45 ports for either IEEE 802.3 10BASE-T (10 Ethernet connections. These ports are labeled ETH 0 and ETH 1.

The transmission speed of the Ethernet port is not user-configurable. You set the speed through an autosensing scheme on the PRP which is determined by the network that the Ethernet port is connected to. However, even at an autosensed data transmission rate of 100 Mbps, the Ethernet port can only provide a usable bandwidth of substantially less than 100 Mbps. You can expect a maximum usable bandwidth of approximately 20 Mbps when using an Ethernet connection.

The following LEDs on the front panel indicate traffic status and port selection (

Pressing the reset switch causes a nonmaskable interrupt (NMI) and places the PRP in ROM monitor mode. When the PRP enters ROM monitor mode, its behavior depends on the setting of the PRP software configuration register. For example, if the boot field of the software configuration register is set to:

• 0x0—The PRP remains at the ROM monitor prompt (rommon>) and waits for

a user command to boot the system manually.

• 0x1—The system automatically boots the first Cisco IOS image found in

flash memory on the PRP.

Use flash memory to store multiple Cisco IOS XR software and microcode images that you can use to operate the router. You can download new images to flash memory over the network (or from a local server) to replace an existing image, or to add it as an additional image. The router can be booted (manually or automatically) from any of the stored images in flash memory.

Flash memory also functions as a Trivial File Transfer Protocol (TFTP) server to allow other servers to boot remotely from the stored images, or to copy them into their own flash memory.

The system uses two types of flash memory on PRP-2:

• Onboard flash memory (called bootflash)—Contains the Cisco IOS boot

image

To ensure that there is adequate air flow to prevent overheating inside the card cages, keep the front and back of the router unobstructed. We recommend at least 6

inches (15.24 cm) of clearance.

Caution You should inspect and clean the air filter one time per month (more often in dusty

environments). Do not operate the router without an air filter installed.

The blower module controller card monitors and controls operation of three variable-speed fans in the blower module.

Preparing for Installation

Before installing your router, you must consider power and cabling requirements that must be in place at your installation site, special equipment for installing the router, and the environmental conditions your installation site must meet to maintain normal operation. This chapter guides you through the process of preparing for router installation.

The shipping package for the router is engineered to reduce the chances of product damage associated with routine material handling experienced during shipment.

• The router should always be transported or stored in its shipping package in

the upright position.

• Keep the router in the shipping container until you have determined the

installation site.

Inspect all items for shipping damage. If an item appears damaged, contact a Cisco customer service representative immediately.

Laser Safety

Single-mode Cisco XR 12410 router line cards are equipped with lasers. The lasers emit invisible radiation. Do not stare into open line card ports. Observe the following warning to prevent eye injury:

Safety Guidelines

Warning

Avoid exposure to laser radiation. Do not stare into an open aperture, because invisible laser radiation may be emitted from the aperture when a cable is not inserted in the port.

Preventing Electrostatic Discharge Damage

Many router components can be damaged by static electricity. Not exercising the proper electrostatic discharge (ESD) precautions can result in intermittent or complete component failures. To minimize the potential for ESD damage, always use an ESD-preventive antistatic wrist strap (or ankle strap) and ensure that it makes good skin contact.

Note Check the resistance value of the ESD-preventive strap periodically. The

measurement should be between 1 and 10 megohms.

Before you perform any of the procedures in this guide, attach an ESD-preventive strap to your wrist and connect the leash to the chassis as shown in Note that some versions of the 10-slot chassis do not provide an ESD connection socket in the line card cage area. For those chassis, use an alligator clip to connect the leash to an open metal part of the chassis.

Rack-Mounting Guidelines

The router can be mounted in most 2-post, 4-post, or telco-type 19-inch equipment racks that comply with the Electronics Industries Association (EIA) standard for equipment racks (EIA-310-D). The rack must have at least two posts with mounting flanges to mount the router chassis. The distance between the center lines of the mounting holes on the two mounting posts must be 18.31 inches ± 0.06

inch (46.50 cm ± 0.15 cm). The rack-mounting hardware included with the

router is suitable for most 19-inch equipment racks or telco-style frames.

OL-17441-01

Figure 2-2a shows a free-standing, enclosed rack with two mounting posts in the

front. The router should not be installed in this type of enclosed rack, because the router requires an unobstructed flow of cooling air to maintain acceptable operating temperatures for its internal components. Installing the router in any type of enclosed rack—even with the front and back doors removed—could disrupt the air flow, trap heat next to the chassis, and cause an overtemperature condition inside the router.

Figure 2-2b shows a free-standing, 4-post open rack with two mounting posts in

the front and two mounting posts in the back. The mounting posts in this type of rack are often adjustable so that you can position the rack-mounted unit within the depth of the rack rather than flush-mount it with the front of the rack.

Telco Rack

Chapter 2 Preparing for Installation

Figure 2-2c shows a telco-type rack. The telco-type rack is an open frame

consisting of two posts tied together by a cross-bar at the top and a floor stand at the bottom.

This type of rack is usually secured to the floor and sometimes to an overhead structure or wall for additional stability. The router chassis can be installed in the telco-type rack either in a front-mounted position or a center-mounted position.

In the front-mounted position, you secure the chassis rack-mounting brackets directly to the rack posts (

Site Requirement Guidelines

Site Layout and Equipment Dimensions

To help maintain trouble-free operation, adhere to the following precautions when planning your rack installation:

• Ensure the site of the rack includes provisions for source AC or DC power,

grounding, and network interface cables.

• Allow sufficient space to work around the rack during the installation. You

need:

–

At least 3 feet adjacent to the rack to move, align, and insert the chassis.

–

At least 2 feet in front of the power shelf to insert power entry modules.

• Maintain at least 24 inches (61 cm) of clearance in front of and behind the

chassis for maintenance after installation.

• To mount the router between two posts or rails, the usable aperture (the width

between the inner edges of the two mounting flanges) must be at least

17.7

inches (45.0 cm).

• The height of the router is 37.0 inches (93.98 cm). Most racks accommodate

two routers.

Chapter 2 Preparing for Installation

2-10

• When fully populated with cards, the router can weigh as much as 275 lb

(124.74

kg). To maintain equipment rack stability and to ensure your safety, the rack is provided with stabilizing devices. Make sure you install the stabilizers before installing the router.

• If you use a telco-style rack, the weight of the chassis is cantilevered off of

the two rack posts. Make sure that:

–

The weight of the router does not make the frame unstable.

–

The frame is bolted to the floor and is secured to the building structure using either wall brackets or overhead brackets.

• When mounting the router in a telco-type rack or 4-post rack, be sure to use

all of the screws provided to secure the chassis to the rack posts.

• Install the cable-management brackets included with the router to keep cables

organized. Be sure to:

–

Use appropriate strain-relief methods to protect cables and equipment connections.

–

Make sure that cables from other equipment installed in the rack do not restrict access to the card cages.

Air Flow Guidelines

Cool air is circulated through the router by the blower module located at the top of the chassis. The blower module maintains acceptable operating temperatures for the internal components by drawing in cool air through the air filter in front of the switch fabric and alarm card cage, and circulating the air through both card cages (

Figure 2-6). Each power supply is also equipped with a fan that draws

cooler air into the front of the power supply and forces warmer air out of the back of the chassis.

When selecting a site to install the router, observe the following guidelines:

• Dust free area—The site should be as dust free as possible. Dusty

environments can clog the air filter or power supply intake vents, reducing the cooling air flow through the router. Clogged filters and vents can cause an overtemperature condition in the router.

Cisco XR 12410 and Cisco XR 12810 Router Installation Guide

OL-17441-01

Chapter 2 Preparing for Installation

• Unrestricted air flow—Allow sufficient air flow by maintaining a minimum

of 6

inches (15.24 cm) of clearance at both the inlet and exhaust openings on the chassis and the power modules. If the air flow is blocked or restricted, or if the inlet air is too warm, an overtemperature condition can occur within the router. Under extreme conditions, the environmental monitoring system powers off the router to protect the components.

Temperature and Humidity Guidelines

The operating and nonoperating environmental site requirements are listed in

Table A-4 on page A-5. The router normally operates within the ranges listed in

Table A-4, however, if a temperature measurement is approaching a minimum or maximum parameter it indicates a potential problem. Maintain normal operation by anticipating and correcting environmental anomalies before they approach critical values by properly planning and preparing your site before you install the router.

Power Connection Guidelines

Site Requirement Guidelines

OL-17441-01

You can configure the router with either an AC-input or DC-input power subsystem, so the site power source requirements differ depending on the power subsystem in your router. Ensure all power connection wiring conforms to the rules and regulations in the National Electrical Code (NEC), as well as local codes.

Caution Proper grounding is necessary to avoid damage from lightning and power surges.

NEBS Supplemental Unit Bonding and Grounding Guidelines

Although the router chassis requires a safety earth ground connection as part of the power cabling to PDUs, we also recommend that you connect the central office ground system or interior equipment grounding system to the supplemental bonding and grounding connections on the back of the router chassis (

Figure 2-10). This grounding point is also referred to as the network equipment

building system (NEBS) bonding and grounding studs.

Note These bonding and grounding connections 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 connections to the AC and DC PDUs.

• One grounding lug, which have 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. This lug is similar to those used for the DC-input power supply leads (see

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

• One grounding wires. Although we recommends at least 6-AWG multistrand

copper wire, the wire diameter and length depend on your router location and site environment.

Site Wiring Guidelines

Chapter 2 Preparing for Installation

2-20

When planning the location of the router, consider distance limitations for signaling, electromagnetic interference (EMI), and connector compatibility. I wiring is run for any significant distance in an electromagnetic field, interference can occur between the field and the signals on the wires. Poor wiring can cause:

• Radio interference emanating from the wires.

• Strong EMI, especially when caused by lightning or radio transmitters. EMI

can destroy the signal drivers and receivers in the router, and can even create an electrical hazard by conducting power surges through lines and into equipment.

Note To predict and remedy strong EMI, you may need to consult with experts

in radio frequency interference (RFI).

Site wiring is unlikely to emit radio interference if you use twisted-pair cable with a good distribution of grounding conductors. Use a high-quality twisted-pair cable with one ground conductor for each data signal, when applicable.

f the

OL-17441-01

Chapter 2 Preparing for Installation

Give special consideration to the effect of a lightning strike in your vicinity, especially if the wiring exceeds the recommended distances, or if it passes between buildings. The electromagnetic pulse (EMP) caused by lightning or other high-energy phenomena can easily induce enough energy into unshielded conductors to destroy electronic devices. If you have experienced EMP problems in the past, you may want to consult experts in electrical surge suppression and shielding.

Most data centers cannot resolve infrequent but potentially catastrophic problems without pulse meters and other special equipment. In addition, these problems can take a great deal of time to identify and resolve. We recommend that you take the necessary precautions to avoid these problems by providing a properly grounded and shielded environment, with special attention to issues of electrical surge suppression.

The PRP Ethernet port does not provide external routing functions. Its primary roles are to act as a Telnet port into the router, and to boot or access Cisco software images over a network to which the PRP Ethernet port is directly connected.

Caution Cisco Express Forwarding (CEF) functions on these ports are switched off by

default for security reasons. We strongly caution you to consider the security implications of switching on CEF routing functions on these ports.

Chapter 3 Installing the Cisco XR 12410 Router

In a center-mounted position, an optional set of center-mount brackets are secured to the rack posts and the chassis rack-mounting flanges are then secured to the center-mount brackets. The center-mounted position moves the center of gravity of the chassis closer to the vertical axis of the rack posts, which adds to the security and stability of the rack installation.

Verifying Rack Dimensions

Before you install the chassis, measure the space between the vertical mounting flanges (rails) on your equipment rack to verify that the rack conforms to the measurements shown in

Step 1 Mark and measure the distance between two holes on the left and right mounting

rails.

The distance should measure 18.31 inches ± 0.06 inches (46.5 cm ± 0.15 cm).

Note Measure for pairs of holes near the bottom, middle and top of the

equipment rack to ensure that the rack posts are parallel.

Rack-Mounting the Router Chassis

Figure 3-12.

OL-17441-01

Step 2 Measure the space between the inner edges of the left front and right front

mounting flanges on the equipment rack.

The space must be at least 17.7 inches (45 cm) to accommodate the chassis which is 17.25

inches (43.8 cm) wide and fits between the mounting posts on the rack.
