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 user s will be requir ed to corr ect the inter ferenc e at thei r own expens e.

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 insta llation.

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, tr y to c orrect t he 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.)

Definitions of Service Request Severity

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 degrad ed, 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.

Sev erity 3 (S3) —Operat ional per formance of your net work is impaired , b ut most b usines s
operations remain functi onal. Y ou and Cisco wi ll commit resources during normal business
hours to rest ore service to satisfactory levels.

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

xxviii Cisco 12012 Gigabit Switch Router Installation and Configuration Guide

CHAPTER

1

Product Overview

This chapter provides physical and functional overviews of the Cisco 12012 Gigabit Switch
Router (GSR). It contains physical des criptions of the router hardware and major
components, and functional descriptions of the hardware-related features.

The Cisco 12012 is a member of the Cisco 12000 series of gigabit switch routers. The
Cisco 12012 is aimed at scaling the Internet and enterprise backbones to speeds of
OC-3/STM -1 (155 Mb ps), OC-12/STM-4 (622 Mbps), and OC-48/STM-16 (2.4 Gbps).
The Cisco 12012 is built around a high-speed switch ing fabric t hat is scalable from 5 t o 60
Gbps, providing high-performance to support IP-based local and wide-area networks
(WANs).

The Cisco 12012 has two separate card cages; the upper card cage and the lower card cage.
The upper card cage has 12 user -config urable slots that support a comb ination of line cards
and a Route Processor (RP). The rightmost slot in the upper card cage supports a
non-configurable alarm card. Network interfaces reside on line cards that provide
connection between the router’s switch fabric and the external networks.

The lower card cage has five slots for the cards contai ning the switch fabric: clock and
scheduler cards (CSCs) and switch fabric cards (SFCs). The lower card cage is k e yed ; the
top two slots accept clock and s cheduler cards, and the lower th ree slots accept switch fabric
cards.

You can configure the Cisco 12012 for either source A C operation or source DC operation.
AC-inp ut or DC-input powe r supplies resi de in a powe r supply bay located n ear the bottom
of the frame.

Note The Cisco 12012 does not support a mixture of AC- and DC-input power supplies.

Product Overview 1-1

Physical and Functional Overviews

Warning AC operation requires a minimum configuration of two AC-input power

supplies.

Two blower modules, one mounted at the top of the frame and one mounted at the bottom
of the frame, provide cooling air to the system.

Physical and Functional Overviews

The Cisco 12012 is a modular system consisting of the following components (see
Figure 1-1):

• Frame—a rigid metal structure that is 19-inches (48.3-cm) wide, 21-inches (53.3-cm)

deep, and 56-inches (142.2-c m) high and weighs 75 lb (34 kg) empty . Thr ee sets of rails
in the frame support the other three major components: a card cage assembly and two
blower modules. The frame mounts into either a telco-style or four-post rack that is
secured to the building structure.

• Card cage assembly—a sheet metal enclosure that mounts in the frame. The card cage

assembly consists of the upper card cage, the lo wer card cage, and the power supply bay .
All three components are tied together electrically th rou gh a pas s i ve system backplane
in the back of the card cage assembly. The upper card cage has 12 vertical slots for line
cards and an RP. A unique slot (rightmost slot) in the upper card cage supports an alarm
card. The lower card cage has five horizontal slots for the switch fabric. A removable
air filter in a hinged air filter tray is mounted in front of the lower card cage. The power
supply bay is at the botto m of the card cage assembly; it has slots for up to four A C-input
power supplies or up to two DC-input power supplies.

• Blower modules—two identical blower modules that slide on rails into the top and

bottom of the frame. The y provide cooling air for all of the component s in the card cage.
