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.

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.

Cisco 12006 and Cisco 12406 Router Installation and Configuration Guide

OL-11497-03

xxi

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 Description

Chapter 1 Product Overview

Cisco 12006 and Cisco 12406 routers have the following key features:

• Route Processor (RP)—Slot 5 (bottom slot) is the recommended slot for the

first RP. When the router is equipped with a redundant RP, it can be installed in any of the five regular line card slots.

• Line Cards—Up to five OC-192 line cards, four if redundant RPs are

installed. These slots support the online insertion and removal (OIR) feature so installed cards are hot-swappable: A failed card can be removed and replaced with the router powered on.

• Clock and Scheduler Cards (CSCs) and Switch Fabric Cards (SFCs)—Two

dedicated hot-swappable slots for CSCs; three dedicated hot-swappable slots for SFCs.

Note The Cisco 12006 Router uses 2.5-Gbps switch fabric; the

Cisco

12406 Router uses 10-Gbps switch fabric. You cannot mix

2.5-Gbps switch fabric cards and 10-Gbps switch fabric cards in a chassis. The router will not operate with a mix of switch fabric card types.

Note When operating your router with a single CSC, the second CSC slot

must have a CSC blank filler (MAS-GSR6-CSCBLNK=) installed to ensure EMI compliance.

• Two dedicated alarm card slots (for 1+1 redundancy)

• Alarm and Illumination—Alarm and illumination for operating ranges in the

card cage, clock and scheduler card, and switch fabric card bays.

• Two hot-swappable AC-input power supplies or DC-input power entry

modules (PEMs).

Note When operating your router on a single AC-input power supply or

DC-input PEM, the second power module bay must have a blank filler (MAS-GSR-PWRBLANK=) installed to ensure EMI compliance.

Chapter 1 Product Overview

Multigigabit Crossbar Switch Fabric

• System clock—The system clock synchronizes data transfers between line

cards or between the RP and a line card, through the switch fabric. In systems with redundant CSCs, the two system clocks are synchronized so that if one system clock fails, the other clock takes over. The system clock signal is sent to all line cards, the RP, and switch fabric cards.

• Scheduler—The scheduler handles requests from the line cards for access to

the switch fabric. When the scheduler receives a request from a line card for switch fabric access, the scheduler determines when to allow the line card access to the switch fabric.

• Switch fabric—The switch fabric carries the user traffic between line cards or

between the RP and the line cards. The switch fabric card contains only the switch fabric circuitry and receives scheduling information and system clock information from the CSC.

The SFC contains only the switch fabric circuitry, which carries user traffic between line cards or between the RP and the line cards. The SFC receives scheduling information and the system clock sent from the CSC.

Nonredundant and Redundant System Configurations

OL-11497-03

Cisco 12006 and Cisco 12406 routers are available in two system configurations:

1. Nonredundant configuration that includes one CSC and one power supply.

When you order a Cisco 12006 or Cisco 12406 Router, the nonredundant configuration is shipped by default.

2. Redundant configuration that includes two CSCs and two power supplies.

For the redundant configuration, EMI compliance and cooling requirements are met by having two CSCs and two power supplies installed in the system.

For the nonredundant configuration, EMI compliance and cooling requirements are met only when blank fillers are installed in place of either (or both) the second (unused) CSC slot or the second (unused) power supply bay.

Note When operating your router with a single CSC, the second CSC slot must have a

CSC blank filler (MAS-GSR6-CSCBLNK=) installed to ensure EMI compliance.

Chapter 1 Product Overview

Multigigabit Crossbar Switch Fabric

Switch Fabric Switching Capacity and Router Type

The Cisco 12006 Router is based on a 2.5-Gbps switch fabric, where each CSC or SFC provides a 2.5-Gbps full-duplex connection to each line card in the system. The 2.5-Gbps switch fabric consists of the 12006 Card (product number 12006-CSC=) and the 12006 (product number 12006-SFC=). The 2.5-Gbps switch fabric for the Cisco

12006 Router can be identified by the Cisco identification labels on the switch fabric cards (SFCs and CSCs): The CSC is labeled CSC-30/120 and the SFC is labeled SFC-30/120.

The Cisco 12406 Router is based on a 10-Gbps switch fabric, where each CSC or SFC provides a 10-Gbps full-duplex connection to each line card in the system. The 10-Gbps switch fabric consists of the Clock and Scheduler Card (product number GSR6-CSC=) and the Switch Fabric Card (product number GSR6-SFC=). The 10-Gbps switch fabric cards are labeled simply CSC and SFC.

Note You cannot mix 2.5-Gbps switch fabric cards and 10-Gbps switch fabric cards in

a chassis. The router will not operate with a mix of switch fabric card types.

Advanced Clock and Scheduler

Advanced Switch Fabric Card

Switch Fabric Redundancy

Equipping the router with two CSCs provides data path, scheduler, and reference clock redundancy. The interfaces between the line cards and the switch fabric are monitored constantly. If the router detects a loss of synchronization (LOS), it automatically activates the data paths of the redundant CSC, and data flows across the redundant path. The switch to the redundant CSC occurs within 0.5 second, with little or no loss of data.

Chapter 1 Product Overview

Maintenance Bus

The Cisco 12006 and Cisco 12406 router maintenance bus and MBus modules manage the maintenance functions of the system. The MBus is integrated into the backplane and consists of two separate buses, providing MBus redundancy.

Both MBus networks are linked to all the following items:

• Route processor and line cards

• CSCs, SFCs, and alarm cards

• Power modules

• Blower module

The MBus module located on each component communicates over the MBus and is powered by DC voltage directly from the alarm card. The MBus performs the functions of power-up/down control for each component, component (device) discovery, code download, diagnostics, and environmental monitoring and alarms.

Maintenance Bus

Power-Up/Down Control

Each MBus module directly controls the DC-DC converters on the component on which it is mounted, based on commands the component receives from its on-board EPROM and from the RP. Each MBus module is tied directly to DC voltage from the alarm card.

When power is applied to the router, all MBus modules immediately power up. The MBus modules on the RP and CSC immediately turn on the DC-DC converter, powering up the respective card. The line card MBus module waits to power up the line card until it receives a command from the RP.

Device Discovery

The RP uses the MBus to detect the system configuration. The RP sends a message over the MBus requesting identity information from all installed devices. The responses provide component type, as well as slot numbers for the line cards, CSCs, SFCs, and alarm cards.

Maintenance Bus

Code Download

A portion of the line card operating software can be downloaded from the RP to the line card over the MBus. Because the MBus is relatively slow compared to the switch fabric, only enough code is downloaded to the line card for it to access the switch fabric and complete the download process.

Diagnostics

The diagnostic software image is downloaded from the RP to the line card during the test sequence.

Environmental Monitoring and Alarms

The MBus module on each component monitors the environment of that component as follows:

• Line cards and the RP are monitored for temperature by two temperature

sensors mounted on each card. The MBus module makes voltage adjustments through software for the +2.5 converters.

• Clock and scheduler cards and switch fabric cards are monitored for

temperature by two temperature sensors mounted on each card. The MBus module makes voltage adjustments through software for the +2.5 +3.3

VDC converters.

Route Processors

Each Cisco 12006 and Cisco 12406 router has one main system (or route) processor. The route processor (RP) processes the network routing protocols and distributes updates to the Cisco Express Forwarding (CEF) tables on the line cards. The RP also performs general maintenance functions, such as diagnostics, console support, and line card monitoring.

Route Processor Functions

The RP performs the following are primary functions:

• Downloading the Cisco IOS software to all of the installed line cards at

power-up

• Providing a console (terminal) port for router configuration

• Providing an auxiliary port for other external equipment, such as modems

• Providing an IEEE 802.3, 10/100-megabit-per-second (Mbps) Ethernet port

for Telnet functionality

• Running routing protocols

Route Processors

OL-11497-03

• Building and distributing routing tables to the line cards

• Providing general system maintenance functions for the router

The RP will function in any slot in the line card/RP card cage, but slot 5 is the recommended slot. If the router is equipped with an optional, redundant route processor, it can be installed in any of the remaining five slots.

The RP 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 RP. The MBus connection allows the RP to download a system bootstrap image, collect or load diagnostic information, and perform general, internal system maintenance operations.

Route Processors

Route Processor Types

Two types of RPs are available for Cisco 12006 and Cisco 12406 routers, the Gigabit Route Processor (GRP), and the Performance Route Processor (PRP).

Each of these route processor types is reviewed in the following sections:

• Gigabit Route Processor, page 1-16

• Performance Route Processor, page 1-25

When not explicitly specified, this document uses the term route processor (RP) to indicate either the GRP or the PRP.

Note If you install a second RP for redundancy, the second RP must be of the same type

as the primary RP.

The soft reset switch (see Figure 1-6) causes a nonmaskable interrupt (NMI) and places the GRP in ROM monitor mode. When the GRP enters ROM monitor mode, its behavior depends on the setting of the GRP software configuration register. (For more information on the software configuration register, see the “Configuring the Software Configuration Register” section on page 4-1.)

Line Cards

Cisco 12006 and Cisco 12406 routers come pre-installed with the number and type of line cards that you ordered. Line cards and RPs can be installed in two basic combinations to support RP redundancy and a variety of physical network media:

• Nonredundant RP—One RP and up to five Cisco 12000 Series Router line

cards.

• Redundant RPs—Two RPs and up to four Cisco 12000 Series Router line

cards.

Line cards can be installed in any slot—zero (0) through five (5)—in the card cage. Slot number 5 is the recommended default RP slot. Single-mode and multimode line cards are shown in

Line cards provide the interfaces to the router’s external physical media. External connections are made from the front of the chassis to the connectors on the line card face plates. The line cards communicate with the RP and exchange packet data with each other through the switch fabric cards in the switch fabric and alarm card cage.

Figure 1-10.

OL-11497-03

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

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

A cable-management bracket attaches to the faceplate of each line card to manage and organize the network interface cables connected to the individual ports on the line card.

Line cards installed in the router support online insertion and removal (OIR), which means you can remove and replace a line card while the router remains powered up.

Note For detailed instructions on removing, replacing, and configuring the line cards,

Alarm Output Function

The alarm output function consists of a group of relays, LEDs, and their associated drivers connected to an output port on the MBus module.

The alarm output function is controlled by the software on the RP. When a signal is received from the RP, the MBus module on the alarm card activates specific relays to signal an alarm condition. There are three alarm condition severity levels: critical, major, and minor. The critical, major, and minor LEDs are paired for redundancy to protect against a single failed LED.

Note Alarm cards for some Cisco 12000 series routers have both audible and visible

alarm indicators. The alarm card for the Cisco provides only visible alarm indicators as local alerts to unusual conditions in the router.

The IOS software running on the RP determines whether a given alarm condition is a critical, major, or minor alarm. Typing the show commands sh gsr table and sh env all will give you the table of limits and current readings for the LEDs.

Chapter 1 Product Overview

12006 and Cisco 12406 routers

Clock and Scheduler Card and Switch Fabric Card Status

The alarm card provides OK and FAIL indications for all clock and scheduler cards and switch fabric cards in the system. Redundant signals from the fabric cards are brought out to the LEDs on each alarm card. The alarm card does not control how these LEDs are used.

The MBus auxiliary power supply consists of a 50W DC-DC power supply and some current-sharing circuitry. Because the alarm card itself is powered by this supply, the on-board MBus module can report problems with the supply only when the redundant alarm card is in the chassis and providing MBus power.

Alarm Card Status

The ENABLED/FAIL pair of LEDs labeled MBUS indicate the status of the alarm card. The green ENABLED LED indicates that the MBus module on the alarm card is operating properly. The yellow FAIL LED indicates that the alarm card has detected an error in itself or with the MBus power supply.

OL-11497-03

Chapter 1 Product Overview

Power Source Monitoring

The alarm card monitors the power modules and signals when there is a condition outside the normal range of operation. It discloses problems such as the following:

• Power source voltage is not being provided to a component

• A fault exists in the power source or power module

• Output voltage—Voltage monitor signal is outside the allowable range

• Output current—Current monitor signal is outside the allowable range

Alarm Relay Contact Connector

The 9-pin D-type alarm relay contact connector on the faceplate of the alarm card (see

Figure 1-11) is used to connect external alarm indication equipment to the router so that alarm indicator signals in the router can be repeated elsewhere outside the router.

The pins on this connector are tied directly to the critical, major, and minor alarm relay contacts (normally open, normally closed, and common). Any event that causes one of the alarm LEDs on the alarm card faceplate to go on also activates the corresponding relay contact closure. The relay interface is rated at a maximum of 2A, 60V, or 50VA, whichever is greater.

Power Subsystems

Because alarm contact cables are entirely dependent on site-specific circumstances, alarm connector cables are not available from Cisco. For information about alarm connector wiring requirements and the pinout for the alarm connector interface, see the Specifications” section on page A-6.

Chapter 1 Product Overview

Power Distribution

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

Blower Module

The router chassis backplane distributes -48 VDC power throughout the router and to all cards in the card cages.

All cards have multiple DC-DC converters that convert the -48 VDC into +2.5

VDC, +3.3 VDC, +5 VDC, and other voltages as required by the line card. The DC-DC converters are turned on by the MBus modules under the control of the RP and MBus software.

Power for the blower module is supplied directly from the backplane through a connector in the PDU that passes DC voltage from the backplane to the blower module. An blower module controller card in the blower module converts –48

VDC into DC voltage that powers the blower module fans.

Blower Module

Cisco 12006 and Cisco 12406 routers are equipped with a blower module to distribute air within the chassis. The blower module is located on the rear of the chassis. (See through two air filters on the side of the chassis, pulls the air through the chassis card cages, and expels it through exhaust vents on the back of the blower module. (See

Figure 1-17.)

Caution Exhaust from other equipment vented directly into the router air inlet may cause

overheating.

The front, back, and sides of the router must remain unobstructed to ensure adequate air flow and prevent overheating inside the chassis. Allow sufficient air flow by maintaining 6 openings on the chassis.

Blower Module

If the air temperature inside the RP and line card cage rises, the system environmental monitor shuts down all internal power to prevent equipment damage from excessive heat.

If the system detects that one of three fans within a blower module has failed, it displays a warning message on the console screen. If multiple fans fail, the system shuts down to prevent equipment damage.

1-50

Caution Excessive bending in an interface cable can degrade performance.

The cable-management system (see Figure 1-19) consists of the following components:

• One vertical cable-management bracket on the chassis

• One line card cable-management bracket on each line card

When you face the front of the router chassis, the chassis cable-management bracket is installed on the left side of the chassis, adjacent to the line card and RP card cage. The chassis cable-management bracket organizes the line card and RP cables to keep them from binding, and it eliminates interference when access to the front of the chassis is necessary for maintenance and reading the LEDs.

A line card cable-management bracket attaches to each line card with captive screws. Cable ties on the bracket hold the network interface cables in place, keep the cables organized relative to their assigned connectors, and manage the bend radius of each cable as it enters the connector on the line card.

Chapter 1 Product Overview

On line cards with multiple ports, the line card cable-management bracket keeps the network interface cables organized when your remove and replace the line card. You can unplug the network interface cables from their connectors on the line cards and leave the cables bundled in the line card cable-management bracket while you remove the bracket from the line card. That way, when you replace the line card, the network interface cables are already aligned with the correct line card cable connectors.

Preventing Electrostatic Discharge Damage

• Have a second person help lift the equipment; avoid lifting the equipment

alone.

• Ensure that your footing is solid; balance the weight of the object between

your feet.

• Lift the equipment slowly; never move suddenly or twist your body as you

lift.

• Keep your back straight and lift with your legs, not your back. If you must

bend down to lift the equipment, bend at the knees, not at the waist, to reduce the strain on your lower back muscles.

• Always disconnect all external cables before lifting or moving the router.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage to circuit boards can occur if proper grounding is not established. The boards can produce intermittent or complete failures if they are mishandled.

When handling circuit boards, observe the following guidelines to prevent ESD damage:

• Always use an ESD-preventive ankle or wrist strap and ensure that the strap

makes adequate contact with your skin.

Site Requirement Guidelines

Airflow

OL-11497-03

The air circulation system for Cisco 12006 and Cisco 12406 Routers consists of one blower module mounted at the rear of the chassis. The blower module maintains acceptable operating temperatures for the internal components by drawing cooling air in through replaceable air filters located on the right side of the chassis. Air circulates through the card cage and exhausts at the rear of the chassis.

Observe the following guidelines when selecting a site in which to install Cisco

12006 and Cisco 12406 Routers:

• Dust free—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. This can cause an overtemperature condition in the router.

• 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

Site Requirement Guidelines

air is too warm, an overtemperature condition can occur within the router. Under extreme conditions, the environmental monitoring system shuts down the power to protect the router components.

Temperature and Humidity

The operating environmental site requirements are listed in Appendix A, “Technical Specifications.” The temperature and humidity ranges listed are those within which Cisco 12006 and Cisco 12406 Routers will continue to operate. You can maintain normal operation by anticipating and correcting environmental irregularities before they approach critical values.

The environmental monitoring functionality built into Cisco 12006 and Cisco

12406 Routers protects the system and components from potential damage from overvoltage and overtemperature conditions. To assure normal operation and avoid maintenance difficulty, plan and prepare your site before you install the router.

entry modules (PEMs) require an external DC circuit breaker for each DC power source:

–

Original series Cisco 12006 and Cisco 12406 router input power shall not draw more than 45A max. @ 40.5VDC form each DC power source.

–

Enhanced series Cisco 12006 and Cisco 12406 router input power shall not draw more than 60A max. @ 40.5VDC from each DC power source.

• Provide a dedicated power source for each power entry module installed in

the router.

• Install an uninterruptable power source where possible.

Chapter 2 Preparing for Installation

Grounding Connections

Before you connect power or turn on your Cisco 12006 or Cisco 12406 Router, you must provide an adequate system ground for the router. The equipment grounding should be in accordance with local and national electrical codes.

For installations other than in a network equipment building system (NEBS) environment, you may chose to rely on the safety earth ground connection supplied via the International Electrotechnical Commission (IEC) 320 inlets for AC-powered units and the main terminal block ground connection for DC-powered units.

• On Cisco 12006 and Cisco 12406 Routers configured for AC-input

operation, the AC PDU is equipped with two three-wire electrical grounding-type connectors that accept three-wire, grounding-type AC power cords such as the power cords shipped with the router. This is a safety feature.

Chapter 2 Preparing for Installation

• On Cisco 12006 and Cisco 12406 Routers configured for DC-input

operation, the DC PDU is equipped with two DC power connector blocks, each with wire-connection terminals for connecting the negative lead (top terminal), the positive lead (middle terminal), and the ground lead (bottom terminal). This is a safety feature.

If the router is installed in a NEBS environment, we strongly recommend that you connect the central office ground system or interior equipment grounding system to the supplemental bonding and grounding point on the router chassis. This grounding point consists of three threaded inserts is located on the side of the chassis near the back of the chassis. (See NEBS bonding and grounding receptacle, and is intended to satisfy the Telcordia NEBS requirements for supplemental bonding and grounding connections.

Site Requirement Guidelines

Site Wiring

This section presents site wiring guidelines for setting up the plant wiring and cabling at your site. When planning the location of the new system, consider the following:

• Electromagnetic interference (EMI)

• Distance limitations for signaling and unshielded conductors

Electromagnetic Interference

EMI can occur between the signals on the wires and external or ambient EMI fields when the wires are run for any significant distance. Bad wiring practice can result in radio interference emanating from the plant wiring.

Chapter 2 Preparing for Installation

Warning

Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal drivers and receivers in the Cisco Router, can create an electrical hazard by conducting power surges through lines, and can damage the equipment.

To predict and remedy strong EMI, you may need to consult experts in radiofrequency interference (RFI).

If you use twisted-pair cable in your plant wiring with a good distribution of grounding conductors, the plant wiring is unlikely to emit radio interference. If you exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable.

Distance Limitations

If wires exceed recommended distances, or if wires pass between buildings, give special consideration to the effect of a lightning strike in your vicinity. The electromagnetic pulse (EMP) caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic devices. If you have had problems of this sort in the past, you may want to consult experts in electrical surge suppression and shielding.

Chapter 2 Preparing for Installation

Unpacking and Repacking the Router

Most data centers cannot resolve the infrequent but potentially catastrophic problems just described without pulse meters and other special equipment. These problems can cost a great deal of time to identify and resolve, so take precautions by providing a properly grounded and shielded environment, with special attention to issues of electrical surge suppression.

Unpacking and Repacking the Router

The shipping package for Cisco 12000 series routers is engineered to reduce the potential of product damage associated with routine material handling experienced during shipment. To minimize potential damage to the product, transport these products in their Cisco-specified packaging. Failure to do so may result in damage to the router or degradation of its performance. Also, do not remove the Internet router from its shipping container until you are ready to install it. The router should always be transported or stored in an upright position. Keep the router in the shipping container until you have determined where you will install it.

Refer to the unpacking instructions (Cisco 12006 and 12406 Router Unpacking and Repacking Instructions document number 78-16104-xx) that came with the router to unpack it from the shipping pallet and verify the contents. This document also includes instructions to repack the router if you need to transport it.

If you do not receive everything you ordered, contact a customer service representative for assistance. See the section titled, Assistance, page -xx.
