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.”
