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.

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

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.)

http://www.cisco.com/en/US/products/products_psirt_rss_feed.html

Reporting Security Problems in Cisco Products

Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you might have identified a vulnerability in a Cisco product, contact PSIRT:

•Emergencies — [e-mail]

An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.

•Nonemergencies — [e-mail]

In an emergency, you can also reach PSIRT by telephone:

•1 877 228-7302

•1 408 525-6532

Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product to encrypt any sensitive information that you send to Cisco. PSIRT can work from encrypted information that is compatible with PGP versions 2.x through 8.x.

Never use a revoked or an expired encryption key. The correct public key to use in your correspondence with PSIRT is the one linked in the Contact Summary section of the Security Vulnerability Policy page at this URL:

Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: [phone] (Australia: 1 800 805 227)

EMEA: [phone]

USA: 1 800 553-2447

For a complete list of Cisco TAC contacts, go to this URL:

http://www.cisco.com/techsupport/contacts

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is “down,” or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

About This Guide

Obtaining Additional Publications and Information

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.

Product Overview

This chapter provides an overview of the Cisco 12016, Cisco 12416, and Cisco 12816 series routers. It contains physical descriptions of the router hardware and major components, as well as functional descriptions of the hardware-related features.

Introduction

The routers described in this guide are part of the Cisco 12016, Cisco 12416, and Cisco 12816 series routers and include:

•The original Cisco 12016, Cisco 12416, and Cisco 12816 series routers.

•The newer Cisco 12016, Cisco 12416, and Cisco 12816 enhanced series routers. The enhanced series of routers use higher capacity power supplies, more powerful blower modules, and have newly designed front doors.

The capacity of the router switch fabric differentiates each model:

•Cisco 12016 Router—2.5-Gbps switch fabric

•Cisco 12416 Route—10-Gbps switch fabric

•Cisco 12816 Router—40-Gbps switch fabric

Other than their various capacities, these routers are nearly identical. Differences between each router are described where necessary, and unless otherwise noted, the information in this publication applies to all routers.

Physical and Functional Description of Router

Physical and Functional Description of Router

The Cisco 12000 series router chassis is a sheet-metal enclosure that houses router components. The major components consist of three power supplies, upper and lower line card cages, a switch fabric card cage, and upper and lower blower modules. Power is distributed to these components over the chassis backplane.

All router models contain the following major components (Figure 1-1):

•Power shelf and power supplies—Three AC or DC power entry modules (PEMs) provide power to the router. See the “AC and DC Power Subsystems” section on page 1-4 for additional information.

•Upper blower module—Supplies cooling air to the upper half of the router so it does not overheat. See the “Blower Module” section on page 1-44 for additional information.

•Upper and lower cable management brackets—Used to neatly route line card cables. See the “Upper and Lower Cable Management Brackets” section on page 1-43 for additional information.

•Upper Line card and Route Processor card cage—Has 8 user-configurable slots that support a combination of line cards, a route processor (RP), and an alarm card. See the “Alarm Card, Line Card, and Rout Processor Overview” section on page 1-21 for additional information.

•Switch fabric card cage—Located behind the air filter door, this card cage contains 5 slots for the switch fabric card set. The switch fabric card set is made up of 3 switch fabric cards (SFCs) and 2 clock scheduler cards (CSCs). See the “Switch Fabric Overview” section on page 1-19 for additional information.

•Lower Line card and Route Processor card cage—Has 8 user-configurable slots that support a combination of line cards, a redundant route processor (RP), and an alarm card. See the “Alarm Card, Line Card, and Rout Processor Overview” section on page 1-21 for additional information.

•Lower blower module—Supplies cooling air to the lower half of the router so it does not overheat. See the “Blower Module” section on page 1-44 for additional information.

•Chassis backplane (not shown)—Distributes power to card cages and to the blower modules.

Physical and Functional Description of Router

AC and DC Power Subsystems

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

Standard AC Power Shelf

The standard AC-input power subsystem consists of a single-level AC-input power shelf that house three (2000 W original series or 2400 W enhanced series) AC power supplies which supply full redundant power to the router. Figure 1-2 shows the standard power shelf housing original series 2000 W power supplies.

The power supplies participate in an N+1 redundant current-sharing scheme that is divided among all three power supplies. If one power supply fails, the system can continue to operate temporarily, (depending on your system configuration) with the remaining two power supplies. Failed power supplies should be replaced as soon as possible to ensure full redundancy.

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.
