CHAPTER

Product Overview

This chapter provides physical and fun ctional overviews of the Cisco 7204 router. It contains physical descriptions of th e r oute r ha rdware an d m ajo r c om ponen t s, and f unc ti onal d esc ripti on s o f hardware-related features. Descriptions and examples of software commands are included only when they are necessary for rep lac ing, inst al ling , co nfigurin g, or m aint ai ning t he r oute r hardware .

The Cisco 7204 i s p art of the C isco 7200 series routers, wh ich co nsi sts of t he 2- slot Cisco 7202, 4-slot Cisco 7204 and Cisco 7204VXR, and 6-slot Cisco 7206 and Cisco 7206VXR. The Cisco 7204 supports multiprotocol, multimedia routing and bridging over a wide variety of LAN and WAN interface types.

Network interfaces reside on port adapters that provide the connection between the router’s three Peripheral Compone nt I nte rconn ec t ( PCI) buses and exter nal net works. Th e Cisc o 7 204 has fou r s lot s (slot 1 through slot 4) for the port adapters, one slot for an Input/Output (I/O) controller, and one slot for a network processing engine. You can place the port adapters or service adapters in any of the four available slots.

There are bays for up to two AC-input or DC- input power supplie s. The Ci sco 7 204 wil l operat e with one power supply. While a second power supply i s n ot r equi red, it a llows loa d sha ring a nd i ncre ased system availability.

OL-5101-02

Note The Ci sco 7204 does not sup por t a mi x ture of AC- and DC-i nput p ower.

The Cisco 7204 provide s the following features :

• Online insertion and removal (OIR)—Allows you to add, repl ace , or re move port a dap te rs wit ho ut

interrupting the syste m or enter ing any cons ole comm ands.

• Dual hot-swappable, load-sharing power supplies—Provide system power redundancy; if one power

supply or power source fails, the other power supply maintains system power without interruption. Also, when one power supply is powered off and removed from the router, the second power supply immediately takes o ver the router’s power requirements without interrupting normal operation of th e router.

• Environmental monitoring and repo rting fun ctions —Allow you to maintain normal system

operation by resolving adverse environment al con dit ions befor e any lo ss of o pe ratio n.

• Downloadable software—Allows you to load new images into Flash memory remotely, without

having to physically acc ess t he Cisco 7204 router, for fast, rel iab le upg rade s.

Chapter 1 Product Overview

The Cisco 7204 router comes equipped with one 280W AC-input or one 280W DC-input power supply. A fully configured Cisco 7204 router operates with only one installed power supply; however , a second, optional power supply of the same type provides hot- swappable, load -sharin g, redunda nt power.

Figure 1-3 shows the re ar of a C isco 7204 router configu red w it h a si ngle AC-input power su pply. (A

power supply filler plate is installed over the second power supply bay.)

supplies must be of the same type (two AC-input power supplies or two DC-inpu t power supplies).

The power supply has the router’s main power switch and either an AC-input power receptacle or a hardwired DC-input power cabl e (depend ing on the type of installe d power supply).

Adjacent to the power supply bays there are two chassis ground receptacles that provide a chassis ground connection for ES D eq uipm en t or a two- hole g roundi ng lug ( refe r to Figu re 1 -3).

Three internal fans draw cooling air into chassis and across internal components to maintain an acceptable operatin g temperature. (Refer to Figure 1-3.) The three fans are enclosed in a tray that is located in the subchassis.

Caution To ensure the proper flow of cooling air across the internal components, make sure blank port adapters

are installed in unoccupied port adapter slot s, and power supply filler plates are installed in unoccupied power supply bays.

The I/O controller, port adap ters, power suppli es, an d network proc essing engine slid e into thei r respective chassis slots and connect directly to the router’s midplane; there are no internal cables to connect. The midplane distributes DC power from the power supplies to the I/O controller, port adapters, fan tray, and network processing engine.

The midplane also identifies OIR of the port adapters, bridges the PCI buses from the port adapters to packet static random-access memory (SRAM) on the network processing engine, arbitrates traffic across the PCI buses, and gene rates the c lock sign als for the por t ad ap ter s on ea ch PCI bus.

The Cisco 7204 op er ate s a s eit her a tab let op or r ack -mou nt ed u ni t. A ra c k-moun t kit is st anda rd equipment included with all Cisco 7204 routers when they are shipped from the factory. The kit provides the hardware needed to mo unt the ro uter in a sta ndard 19-inch eq uipment ra ck or a 2-p ost rack. Steps for installing the Cisco 7204 router in an equipment rack are explained in Chap ter 3, “Installing the

Cisco 7204.” I f you a re no t rac k-mou nt ing you r C isco 7204, place it on a stur dy t able top or p lat fo rm.

A fully configured Cisco 7204, with two installed power supplies and all chassis slots filled, weighs approximately 50 pounds (22.7 kilograms [kg]). For clearance requirements and rack-mount installation considerations, refer to the section “Site Environment” in Chapter 2, “Preparing for Installation.”

Functional Overview

Chapter 1 Product Overview

The Media Acce ss Control (MAC) or hardware address is a standardized data link layer address that is required for certain net work inter face types. Th ese ad dresses are n ot used by other devices in the network; they are specific and unique to each port. The Cisco 7204 uses a specific method to assign and control the MAC addresses of its port adapters. For a description of the MAC-layer address, see the section “MAC Address ” section on page 1-25 in this chapter.

Port adapter slots maintain the same slot number regardless of whether other port or service adapters are installed or removed. However, when you move a port adapter to a different slot, the port adapter’s slot number changes to refle ct the new slot numbe r.

You can identify port adapter slots by using software commands to display information about a specific port or service adapter or for all port and service adapters in the Cisco 7204. To display information about all port adapte r slot s, use th e sh ow in terf ac es command. To display information about a specific port adapter slot, use the show interfaces command with the port adapte r type and slot num ber in the format show interfaces (port adapter type and slo t nu mber/port number). If you abbreviate the command (sh int) and do not specify port adapter type and slot number (or arguments), the system interprets the command as show interfaces and displays the status of all port adapters and ports.

Following is an example of how the show interfaces command, used without arguments, displays status information (inc lu din g th e physi cal por t ada pter n umb er ) for e ach po rt a da pte r in a C is co 7204.

In the following example, most of the status information for each interface is omitted.

Chapter 1 Product Overview

MAC Address

Functional Overview

LAN interfac es (ports) require un ique MA C a ddresses, also kno wn as hardware addresses. T ypically , the MAC address of an interface is stored on a memo ry compone nt that re sides dir ectly on th e interfac e circuitry; however, the OIR feature requires a different met hod. For a descr iption of O IR, refer to the section ““O nline Insert ion and Removal” se ction on p age 1-25”.

The OIR feature allows you to remove a port or service adapter and replace it with another identically configured one. If the new port or ser vice ad apter ma tches the adapt er you removed, th e system immediately brings it on line. In order to allow OIR, an address allocator with a unique MAC addresses is stored in an EEPROM on the router midplane. Each address is reserved for a specific port and slot in the router regardless of whether a port or service adapter resides in that slot. The MAC addresses are assigned to the slots in sequence. The first address is assigned to slot 0, and the last address is assigned to slot 6. This address scheme allows you to remove port and service adapters and insert them into other routers without causin g the MAC addresses to move around the ne twork or be assig ned to mul tiple devices.

Note that if the MAC addresses were stored on eac h port or servi ce ada pter, OIR would not function because you could never replace one adapter with an identical one; the MAC addresses would always be different. Also, each t ime a por t or serv ice ada pte r was re place d, othe r devices on the net work wo uld have to update their data structures with the new address, and, if they did not do so quickly enough, could cause the same MAC address to appear in more than one device at the same time.

Note Storing the MAC addresses for every slot in one central location means the addresses stay with the

memory device on which they are stored.

Online Insertion and Removal

All port and service adapters in the Cisco 7204 support online insertion and remo val (OIR).This functio n allows you to install and r eplace por t and service adapter s while the rou ter is operati ng; you do not nee d to notify the software or shut down the system power. This provides a method that is seamless to end users on the network, mai ntain s al l ro uting info rm ati on, a nd e nsu res se ssion prese rvation.

The following is a functional des cript ion of OIR for bac kgroun d informa tion only; for specific procedures for installing and replacing a port or service adapter in a Cisco 7204 router, refer to the configuration note that was shipped with the port or service adapter hardware.

Caution The network processin g engine a nd the I/O con trolle r are requi red system compone nts that cannot be

removed if the router is operat ing. Removing the network processing engine or the I/O c ontroller while the router is operating w ill c ause the router t o shut d o wn o r crash , and might dam age or d estroy m emory files.

Each port and service adapter has a bus connector that connects it to the router’s midplane. Each midplane connector has a set of tiered pins in three lengths that send specific sig nals to the system as they make contact with the port adapter. The system assesses the signals it receives and the order in which it receives them to determine if a port or service adapter is being removed or inserted into the midplane. From these signals, the system det ermines whether to reinitia lize a new in terface or shut do wn a remove d int erfac e. Fo r ex ample, when ins erting an port a dapter , the lon gest pins make contact wit h the port adapter first, and the sh orte st pin s m ake conta ct last. Th e syste m re cogni ze s the sig na ls a nd th e sequence in wh ich it re c eives them.

Functional Overview

When you remove or inse rt a port o r s ervi ce ad apt er in a Cisco 7204 router, the midpla ne p ins s end signals to notify the system, which then performs as follows:

1. Rapidly sca ns the midpla ne for configur ation cha nges.

2. Initializes all newly inserted port and service adapters, noting any removed port adapter interfaces

and placing them in the adm inistra tively shut down state.

3. Brings all previously configured interfaces on the port adapter back to the state they were in when

they were removed (ser vice adapters do not have interfaces). Any newly inserted interfaces are put in the administratively shut down state, as if they were present (but not configured) at boot time. If a similar port adapter type is reinserted in to a slot, it s ports are conf igured and brought on line up to the port count of the original port adapter.

Environmental Monitoring and Reporting Functions

Environmental monitoring and reporting functions are controlled by the network processing engine and allow you to maintain normal system oper ati on by identifying and resolving adver se co nditi ons prior to loss of operation. The environmental monit oring fun ctions constantly mon itor th e interna l chassis air temperature and DC supply voltages and currents. Each power supply monitors its own voltage and temperature and shuts itself down if it detects a critical condition within the power supply. If conditions reach shutdown thresholds, the system shuts down to avoid equipment damage from excessive heat. The reporting functions periodic ally log th e values of measured parameters so that you c an r etr ieve them for analysis later, and the reporti ng functio ns disp lay warnin gs on the consol e if any of the moni tored parameters exceed de fined thr eshol ds.

Chapter 1 Product Overview

Environmental Monitoring

The environmental monitoring functions use four sensors, two on the network processing engine and two on the I/O controller, to monitor the temperature of the cooling air as it moves through the chassis.

Table 1-8 lists the temperature thresholds for the processor-monitored leve ls of a Cisco 7204 router that

has an installed NPE-100, NPE-150, or NPE-200 .

Before installing your Cisco 7204 you should consider the power and cabling requirements that must be in place at your insta llation si te, th e equipm ent you w ill nee d to install the r outer, and the environmenta l conditions your installation site must meet to maintain normal operation. This chapter guides you through the process of preparing for your router installation.

Safety Recommendations

The following guidelines will help to ensure your safety and protect the equipment. This list does not cover all potentially hazardou s situa tions, so be a lert .

• The installation of your Cisco 7204 should be in compliance with national and local electrical codes.

In the United States, National Fire Protection Association (NFPA) 70, United States National Electrical Code. In Cana da, Can adian Ele ctrica l Code, pa rt I, CC2 2.1. In ot her count ries, International Ele ctrotec hnica l Commission (IEC) 364 , part 1 through part 7.

• Review the safety warnings listed in the document Regulatory Compliance and Safety Information

for the Cisco 7200 Series Routers that accompanied your Cisco 7204, before installing, configuring,

or maintaining the router.

• Never attempt to lift an object that might be too heavy for you to lift by yourself.

• Always turn all power suppli es off (O ) and u nplug a ll power cabl es b ef ore openi ng the cha ssis.

• Always unplug the power cabl e befor e i nstalli ng or r emoving a c hassi s.

• Keep the chassis area clear and dust free during and after installation.

• Keep tools and chassis components away from walk areas.

Safety Recommendations

Lifting Safely

Chapter 2 Preparing for Installation

• Do not wear loose clothing, jewelry (including rings and chains), or other items that could get caught

in the chassis. Fasten your tie or scar f and sle eves.

• The Cisco 7204 with installed AC-input power supplies ships with a three-wire electrical

grounding-type plug, which will only fit into a grounding-type power outlet. This is a safety feature. The equipment gr ounding sho uld be in accorda nce wi th loca l and nati onal elec tric al codes .

• The Cisco 7204 with installed DC-input power supplies ships without the necessary wiring to

connect the router to a DC power source. Input, return, and earth (ground) wiring must be provided by the installation site and installed and protected in accordance with local and national wiring regulations.

• The Cisco 7204 operates safely when it is used in accordance with its marked electrical ratings and

product usage inst ru ctio ns .

A fully configured Cisco 7204 weighs approximately 50 pounds. The chassis is not intended to be moved frequently. Before you insta ll th e ro uter, ensure tha t y our sit e is p ro per ly p re pare d so you c an avoid having to move the chassis later to accommoda te power sources an d network co nnectio ns.

Whenever you lift the chassis or any heavy object, fol low these guideli nes (see Figure 2-1):

• Always disconnect all external cabl es before lift ing or moving the c hassis.

• Do not attempt to lift the chassis by yourself; have someone assist you.

• Ensure that your footing is solid, a nd balance the weight of the objec t betwee n your feet .

• Lift the chassis slowly; never move suddenl y or twis t y our b ody a s yo u lif t.

• Keep your back straight and lift with your l egs, not your back. If you must bend down to lift the

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

• Lift the chassis from the bottom; grasp the underside of the chassis exterior with both hands.

Chapter 2 Preparing for Installat ion

Safety with Electricity

The port adapters and power supplies are designed to be removed and replaced while the system is operating without pre senti ng an elec trical hazard or damage t o the system. H owever, you must power down the system before r em oving or r eplac ing the I/ O c ont roll er a nd n etwor k p roce ssing engi ne.

Follow these basic guidelines when working with any electrical equipment:

• Before beginning any procedures requiring access to the chassis interior, locate the emergency

power-off switch for the room i n whi ch y ou ar e worki ng.

• Disconnect all power and ex ternal cables before installing or removing a chassis.

• Do not work alone when potentially hazardous conditions exist.

• Never assume that power has been d isco nnecte d from a c ircui t; always check.

• Do not perform any action that creat es a pot entia l haz ard t o peopl e or ma kes the e quip ment unsafe .

• Never install equipment that appears damaged.

• Carefully examine your work are a f or possib le ha zard s suc h as m oi st fl oors, u ngr ounde d p ower

extension cables, and m issin g safety gr oun ds.

In addition, use the guidelines that follow when working with any equipment that is disconnected from a power source, but still connected to telephone wiring or other network cabling.

Safety Recommendations

• Never install telephone wiring during a l ightning storm.

• Never install telephone j acks in w et l oca tio ns un less t he j ac k is spe cifically des ig ned f or we t

locations.

• Never touch uninsulated telephone wir es or termin als unless th e telepho ne line has been

disconnected at t he n etwor k in ter face.

• Use caution when instal ling or modifying t elepho ne lines.

Preventing Electrostatic Discharge Damage

Electrostatic dis charge (ESD) damage, which occurs when electronic cards or components are improperly handled, can result in complete or intermittent system failures. The network processing engine, I/O controller, and each port adapter consists of a printed circuit board that is fixed in a metal carrier . Electro magnetic inte rference (E MI) shielding, co nnectors, an d a handle are in tegral c omponents of the carrier. Although the carrier helps protect the boards, use an antistatic strap whenever handling the network processing engine, I/O controller, and port adapters. Handle the carriers by the handle and the carrier edg es on ly; never touc h th e boa rd s or c on ne ctor pin s.

Caution Always tighten the captive installation screws on the network processing engine and I/O controller. (See

Figure 1-4 and Figure 1-9.) These screws prevent accidental removal, provide prope r grounding for the

system, and help ensure that the bus connectors are properly seated in the midplane.

OL-5101-02

Following are guidelines for preventing ESD damage:

• Always use an ESD w rist st r ap or ankl e st rap and e nsur e tha t i t ma kes goo d skin con tac t.

• When handling a removed network processing engine, I/O controller, or port adapter, make sure the

equipment end of your ESD strap is atta ched to an unfinished chassis surface of the router; do not touch the print ed ci rcui t bo ar d, a nd avoid contac t be tw een th e pr in ted ci rcui t bo ar d an d y our

• Ensure the I/O con troller an d networ k processi ng engin e are fully inse rted in the ir respecti ve chassis

slots and their captive installation screws are tightened. The captive installation screws prevent accidental removal, provide proper groundi ng for the syst em, and he lp ensure that th e bus connectors are seated in the midplane.

• Ensure that each p ort adapter is f ully inse rted in its ch assis sl ot an d the res pecti v e por t ada pter l e v er

is in the locked position.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be

between 1 and 10 megohms.

Site Requirements

The environmenta l monitoring functionality in the Cisco 7204 protects the system and components from potential damage from overvoltage and overtempe rat ur e co ndit ions . To assure normal o pera tio n and avoid unnecessary maintenance, pl an your site co nfiguration a nd prepare your site before installation. After installation, make sure the site maintains an ambient temperature of 32°F through 104°F (0°C through 40°C), and keep the area around the chassis as free from dust as is practical.

The following sections address the site environment requirements for the Cisco 7204.

Chapter 2 Preparing for Installation

AC and DC Power

The AC-input power supply uses a power factor corrector that allows the Cisco 7204 to operate on input voltage and frequency wi thin t he r anges of 1 00 to 2 40 VAC and 50/ 60 Hz.

Note We recommend attaching dual power supplies to independent power sources for full redundancy. W e also

recommend an un int errup tabl e p ower so urce to pro tec t a gai ns t power fai lure s at y our si te . Each AC-input power supply operating at 120 VAC requires a minimum of 5A service. We recommend powering the Cisco 7204 fro m a 15A re ceptac le at the power sour ce.

The DC-input power supply allows the Cisc o 7 204 route r to opera te at –48 VDC nominal in N orth America and –60 VDC in Europe.

Refer to Table 1-1 in “Chapter 1, “Product Overview”” for system power specifications, including input voltage and operating f re quency ra nges.

Plant Wiring

Following are guidelines for setting up the plant wiring and cabling at your site. When planning the location of the new system, consider the distance limitations for signaling, EMI, and connector compatibility, as described in the following sections.

Chapter 2 Preparing for Installat ion

Interference Considerations

When wires a re r un for a ny signi ficant dist an ce i n an el e ctro ma gn etic field, i nte rf eren ce c an oc cur between the field and the signals on the wires. This fact has two implications for the construction of plant wiring:

• Bad wiring practice can result in radio interference emanating from the plant wiring.

• Strong EMI, especi al ly whe n it i s ca use d by ligh tni ng or ra dio tra nsm itters, c an d estroy the sign al

drivers and receivers in the Cisc o 7204, and can even create a n el ec tri cal haz ar d by conduc ti ng power surges through lines and into equipment. (Review the safety warnings in the section “Safety

with Electricity” section on page 2-3”.)

Note T o predict and remedy strong EMI, you may also need to consult experts in radio frequency

If you use twisted-pair cable in your plant wiring with a good distribution of ground ing conductors, the plant wiring is unl ikel y to e mit rad io i n terf er en ce. If y ou exce ed t he re co mmend ed di sta nces, u se a high-quality twisted-pair cable with one ground c onducto r for e ach data signal when applicable.

Site Requirements

interference (RFI).

Warning

A readily accessible two-poled disconnect device must be incorporated in the fixed wiring.

If wires exceed recommen ded distanc es, or if wir es pass betwe en buildings, give special cons iderati on to the effect of a lightn ing strike in your vicinity. The electromagnetic pulse caused by ligh tning or other high-energy phenomena ca n easily cou ple enough energy into unsh ielde d condu ctors to de stroy electronic devices. If you have had problems of this sort in the pa st, you may want to consult experts in electrical surge suppression and shielding.

Distance Limitations and Interface Specifications

The size of your networks and the distances between connections depend on the type of signal, the signal speed, and the transmission media (the type of cabling used to transmit the signals). For example, standard coaxial cable has a greater channel capacity than twisted-pair cabling. The distance and rate limits in the following descriptions are the IEEE recommended maximum speeds and distances for signaling; however, you can usually get good results at speeds and distances far greater than these. For example, the re co mm en de d max i mum rat e for V.35 is 2 Mbps, but it is c omm only us ed at 4 Mbps without any problems. If you understand the electrical problems that might arise and can compensate for them, you should get g ood re sults wit h rates a nd di stan ce s gre ate r t han those sh own here; however, do so at your own risk.

Note We recommend that you do not exceed specified transmission rate and distance limits.

When preparing your site for network conn ections t o the Cisco 7204, you must consider a numb er of factors related to each type of interface:

• The type of cabling required for each type (fiber, thick or thin coaxial, shielded twiste d-pair, or

unshielded twisted- pair ca bling)

OL-5101-02

• Distance limitations for each signal type

• The specific cables you need to connect each interface

Cisco 7204 Installation and Configuration Guide

2-5

Site Requirements

• Any additional interface equipment you need, such as transceivers, hubs, switches, modems,

channel service units (CSUs) , or data servic e units (DSU s)

• Cable pinouts if yo u plan t o build your c able s

Before installing the Cisco 7204, have all additional extern al eq uipment and cabl es on han d. The information listed above is contained in the documentation that is shipped with each port adapter. For example, if you need ATM distance limit ations and pinouts, re fer to th e configurat ion note PA-A3 Enhanced ATM Port Adapter Installation and Configuration. This configurati on not e acco mpanies each PA-A3 enhanced A T M p ort ad apter tha t is shippe d from the f a ctor y as an insta lle d item in a Cisco 7204 and as a FRU.

For ordering information, contact a customer service representative.

Equipment Racks

The rack-mounting hardware included with the Cisco 7204 is suitable for most 19-inch equipment racks and telco-type racks. To easily access FRUs while th e router is installed in a rack, mak e certain yo u hav e access to the front and rea r of the rout er.

Before using a particula r rack, ch eck for obstruct ions (such as a power strip) tha t could impa ir rack-mount installation. If a power strip does impair a rear rack-mount installation, remove the power strip before installing the Cisco 7204 in the rack, then replace it after the chassis is installed. As an alternative, you can mount the Cisc o 7 204 on an eq uipment she lf provided that the rack dim ensions allow you to secure the router to the shel f, and th e overall configuration pe rmits safe installat ion and access. However, we recommend rack-mounting the Cisco 720 4. shows the Cisco 72 04 footpri nt and outer dimensions.

Chapter 2 Preparing for Installation

To use the rack-mounting hardware provided with the Cisco 7204, consider the following guidelines:

• To mount the router bet ween two po sts or r ails using the b rackets, the in ne r cle aran ce ( the wi dth

between the inner sides of the two posts or rails) must be at least 17 inches (43.18 cm ).

• The height of the chassis is 5.2 5 in ches (13 .34 c m).

• When mounting the r outer in 4-po st or t elco- type r acks, be sur e t o us e a ll the screws and br ac kets

provided to secure the chassis to the rack po sts.

• Maintain a minimum clearance of three inches on the right and left of the chassis for the cooling air

inlet and exhaust ports, respe ctively. Avoid placing the Cisco 7204 in an overly congested rack or directly next to another equipment rack; otherwise, the heated exhaust air from other equipment can enter the inlet air vents and cause an overtemperature condition inside the router.

• Always install heavier equipment in the lower ha lf of a rack to maint ain a low center of gravity and

prevent the rack from falling over.

• If you use telco-t ype ra ck s, be sur e tha t th e r ack i s bolt ed t o the floor and sec ur ed bec a use in these

types of installations only one end of the chassis mounts to the two rack posts with the brackets. Ensure that the weight of the chassis doe s not make the rack un stable .

• Install and use the c able-manage ment brack et included wi th the Cisco 7204 to keep cables orga nized

and out of the way of the port adapte rs and I/O contro ller. Consider the equipment a nd cabling that is already installed in the rack. Ensure that cables from other equipment will not impair access to the port adapters, o r r equi re y ou to disco nne ct cable s unne cess ar ily t o perfo rm equi pm ent maintenance or upgrade s.

• If you are planning to install th e cable -man agemen t bracket s on a Cisco 7204 tha t you are

rack-mounting from the front, you must install the cabl e-management bracke ts and the rack-mount brackets before you install the chassis in the rack.

• Provide an adequate c hassi s g round (e art h) co nnec tio n for yo ur ro uter cha ssis.

In addition to the preceding guidelin es, review the precautions for avoidi ng overtemperature conditions in the following section “Site Environment.” To properly install the Cisco 7204 chassis in a rack, refer to the instructions in the “Rack-Mounting the Cisco 7204” section on page 3-1 in Chapter 3, “Installing

the Cisco 7204.”

Site Environment

Table 2-1 lists the operating and nonoperating environmental site requirements. The ranges listed are

those within which the Cisco 7204 will continue to operate; ho we ver , a measuremen t that is approaching the minimum or maximum of a range indicates a potential problem. You can maintain normal operation by anticipating and correcting environmental anomalies before they approach a maximum operating range.

Note We strongly recommend that you provide a ch assis ground connecti o n. Refer to the section

“Providing a Chassis Ground Connection for the Router Chassis” section on page 3 -11 in

“Chapter 3, “Installing the Cisco 7204”” fo r instruct ions.

Preventive Site Configuration: Maintaining Normal Operation

Site Requirements

–

Planning a proper location for the Cisco 7204 and the layout of your equipment rack or wiring closet are essential for successful system operation. Equipment placed too close together or inadequately ventilated can cause system overtemperature conditions. In addition, chassis panels made inaccessible by poor equipment placement can make system maintenance difficult. Following are precautions that can help avoid problems during i nstall atio n and on goin g o pe ratio n.

General Precautions

Follow these general precautions when plan ning yo ur equipm ent loc ations and connect ions:

• Use the show environment command regularly to check th e internal system status. The

General Installation

Warning

To prevent the rack from tipping when installing the router in telco-type racks, ensure that the rack is bolted to the floor and, if necessary, anchored with appropriate fixtures.

To install the chassis in the rack, complete the following steps:

Step 1 On the chassis, ensure that all captive screws on the network processing engine, the I/O controller, and

each power supply are tightened and the port adapter levers are in the locked position.

Step 2 Make sure that your path to the rack is unobstructed. If the rack is on wheels, ensure that the brakes are

engaged or that the rack is otherwise stabilized.

Warning

Step 3 Position the chassis so that the front end is closest to you; then lift the chassis and move it to the rack.

To prevent damage to the chassis or personal injury, never attempt to lift or tilt the Cisco 7204 using the port adapter handles or the I/O controller handle; they are not designed to support the weight of the router. Always have someone help you when installing the Cisco 7204.

Note Two people should perform Step 3 through Step 6.

To prevent injury, avoid sudden twists or moves.

Step 4 Slide the chassis into the rack, pushing it back until the brackets (installed at the front or rear of the

chassis) meet th e mou nt ing stri ps or po sts on bo th sid es of the equ ip ment r ack.

Step 5 While keeping the brackets flush against the posts or mounting strips, position the router so the holes in

the brackets are aligned with those in the mounting strips.

Step 6 Insert all six 10-32 x 3/8 slotted screws (three on each side) through the brackets and into the mounting

strip (use the top and bottom bracket hole s, as shown in Figure 3-2, Figure 3-3, Figure 3-4, and

Figure 3-5). Using a 1/4-inch, flat-blade screwdriver, tighten all the screws.

This completes the procedure for installing the chassis in the rack. Proceed to the “Connecting Port

Adapter Cables” section on page 3-13 in this chapter to continue the installation.

General Installation

The router should alr eady be in the area where you will inst all it, and yo ur install atio n locatio n should already be determ ined. If not, refe r to the “Site Requirements” section on page 2-4 in Chapter 2,

“Preparing for Inst allation. ”

When installing the Cisco 7204 on a workbench or tabletop, ensure that the surface is clean and in a safe location and that you have considered the following:

• The router requires at lea st thre e inche s of clea rance at the i nlet a nd e xhaust ven ts (the r ight an d left

Starting the Cisco 7204

After installing your Cisco 7204 and connecting cables, start the router as follows:

Step 1 Check for the following:

• Each port adapter is inserted in its slot and its respective port adapter lever is in the lock e d posit ion.

• The network processin g engine a nd the I/O con troll er are i nserted in their slo ts and their captive

installation screws are tightened.

• All network interface cables are connected to the port adapters.

• A Flash memory card is installed in its PCMCIA slot.

• Each power cable is connected and secured with the cable-retention clip.

• The console terminal is turned on.

Step 2 At the rear of the router, place the power switch on the power supply in the ON (|) position. Repeat this

if a second power supply is installed. The green OK LED on the power supply turns on.

Step 3 Listen for the fans; y ou shou ld im me dia tely he ar t hem ope rati ng. Step 4 During the boot process, observe the system LEDs. The LEDs on most of the port adapters go on and off

in irregular sequen ce. So me ma y g o on , go out, an d go on agai n f or a sh ort ti me. O n th e I /O c on trol ler, the IO power OK LED comes on immediately.

CHAPTER

Performing a Basic Configuration of the Cisco 7204

This chapter d escribes how to perform a basic configuration for your Cisco 7204. The chapter contains the following sections:

• Using the Enable Secret and the Enable Password, page 4-1

• Configuring the Cisco 7204, page 4-2

• Implementing Other Configuration Tasks, page 4-11

• Chapter 4, “What Do I Do Now?”

This chapter guides you through a basic Cisco 7204 configuration, which is sufficient for you to a ccess your network. Complex configurati on proced ures ar e beyond the scope of this public ation and can be found in the configuration publicati ons listed in the “Re lated Doc umentat ion” section on page xiii” in the Preface.

T o configure the Cisco 7204 from a console, you need to connect a terminal to the router’s consol e por t. Configuration requires access to th e console port on the route r’s I/O control ler.

Using the Enable Secret and the Enab le Passwo rd

The Cisco 7204 is administered using the Cisco command interpreter, called the EXEC. You must boot and log in to the router before you can enter an EXEC command. For security purposes the EXEC has two levels of access to comman ds, user E XEC mod e a nd privileged E XEC mo de .

The commands av aila bl e at the u ser level are a subset of those available at the privileged level. Because many privileged-level EXEC commands are used to set operat ing parame ters, you should password-protect these co mman ds to prevent unauthoriz ed use.

There are two co mm ands y ou ca n use t o set the p assword pr otec ti on:

• enable secret password (which is a very secure, encr ypted pa ssword).

• enable password (which is a less se cu re, or no nenc rypted , p assword) .

You must enter the correct password to gain access to privileged-level commands. The passwords should be different for maxim um s ecur ity. If you enter the s am e p assword for bot h duri ng the set up scr ipt, the system will accept it, but you will rec eiv e a warning message indicating that y ou should enter a dif ferent password.

Cisco 7204 Installation and Configuration Guide

OL-5101-02

Configuring the Cisco 7204

An enable secret password can contain from 1 to 25 uppercase and lowercase alphanumeric characters; an enable password can contain any number of uppercase and lowercase alphanumeric characters. In both cases, a number cannot be the first character. Spaces are also valid password characters; for example, “two words” is a valid password. Lea ding spaces are igno red; trai ling space s are re cogniz ed.

Configuring the Cisco 7204

You can configure the Cisco 7204 using one of the procedu res desc ribed in th e following secti ons:

• Configuring the Cisco 7204 Using AutoIns tall

• Configuring the Cisco 7204 Manually Using the Setup Facility

• Configuring the Cisco 7204 Using Configuration Mod e

Follow the procedure tha t best fits the n eeds of your ne twork configura tio n.

Note You need to ac quir e t he c orr ect n etwo rk ad dre sses f ro m y our sy stem a dm inistr ato r or co nsult y our

network plan to determ ine corr ect addr esses be fore you can compl ete the ro uter configurat ion.

Chapter 4 Performing a Basic Configuration of the Cisco 7204

Before continuing th e configurati on process, check th e current state of the router by entering the show version command. The show version command displays the release of Cisco IOS software that is

available on the router.

Configuring the Cisco 7204 Using AutoInstall

The AutoInstall process is designed to configure the Cisco 7204 automatically after connection to your WAN. For AutoInstall to work p roperly, a Transmission Control Protocol/Internet Protocol (TCP/IP) host on your network must be preconfigured to provide the required configuration files. The TCP/IP host may exist anywhere on the network as long as the following two conditions are maintained:

1. The host mu st be on the remo te side of the router’s synchrono us s erial con ne ction to the WAN.

2. User Da tagram Protocol (UDP) broadcasts to and fr om the router and the TCP/IP host are enabled.

This functionality is coordinated by your system administrator at the site where the TCP/IP host is located. You should not use AutoInstall unless the required files are available on the TCP/IP host. See the publications Configuration Fundamentals Configuration G u ide and Configuratio n Fun dam ent als Command Reference for detailed information about how AutoInstall works.

Complete th e foll owing ste ps to prepar e your Ci sco 7204 for the AutoI nst all pro cess :

Step 1 Attach the appro pria te sync hr onous ser ial ca ble to sync hr ono us s erial in terfa ce 0 on the router.

4-2

Note When powering on or power off the router, wait 30 seconds before powering it on or powering it off again.

Step 2 Turn the power switch on each power supply to the ON (|) position. (This action turns on AC power to

the router.) The router loads the operating system image from Flash memory. If the remote end of the WAN

connection is connec ted and pro perly co nfigured , the AutoIn stall process begins .

OL-5101-02

Chapter 4 Performing a Basic Configuration of the Cisco 7204

Once the AutoInstall process is completed, use th e copy running-config startup-config command to write the configuration data to the router’s nonvolatile random-access memory (NVRAM). Perform the following step to complete this task.

Step 3 At the # prompt enter the following comm and:

Hostname# copy running-config startup-config

Note Completing this step saves the configuration settings that the AutoInstall process created to

NVRAM. If you fail t o do this, your conf iguration will be lost the ne xt time you reload th e router .

Configuring the Cisco 7204 Manually Using the Setup Facility

If you do not pl an to use Aut o Insta ll, d o n ot c on ne ct the ro uter ’s serial (WAN) cable to the channel service unit/data service unit (CSU/DSU). If the serial (WAN) cable is connected to the CSU/DSU an d the router does not h av e a conf igurati on stored in NV RAM, the r outer attempts to run AutoIn stall at st art up. The router may take several minutes to determine that AutoInstall is not set up to a remote TCP/IP host.

Once the router determines that AutoInstall is not configured, it will default to the setup facility. If the serial (WAN) cable is not connected, the router will boot from Flash memory and go automatically into the setup facility.

Note Y ou can run the setup facility any time you are at the enable prompt (#) by entering the command setup.

Configuring Global Parameters

When you first start the setup program, you must configure the global parameters. These parameters are used for controlling system-wide settings. Complete the followin g steps to enter the global parameters:

Step 1 Connect a console termin al to the co nsole port on the I/O control ler, and then boot the rout er.

The system boots from Flash memory. The following information appears after about 30 seconds. When you see this information, you have successfull y booted yo ur router :
