Cisco 7200 Series Overview
The Cisco 7200 series consists of the four-slot Cisco 7204 and the six-slot Cisco 7206. The
Cisco 7200 series routers support multiprotocol, multimedia routing and bridging with a wide
variety of protocols and any combination of Ethernet, Fast Ethernet, Token Ring, Fiber Distributed
Data Interface (FDDI), and serial media. Network interfaces reside on port adapters that provide a
connection between the routers’ three Peripheral Component Interconnect (PCI) buses and external
networks. Port adapters can be placed in any available port adapter slot, in any desired combination.
The front of the Cisco 7200 series routers provides access to an Input/Output (I/O) controller and up
to four or six network interface port adapters. The I/O controller has a local console port for
connecting a data terminal (or data terminal equipment [DTE]) and an auxiliary port for connecting
a modem (or other data communications equipment [DCE]) or other devices for configuring and
managing the router; two Personal Computer Memory Card International Association (PCMCIA)
slots for Flash memory cards; and an optional Fast Ethernet port. The Fast Ethernet port provides a
100-Mbps connection to the network. Figure 1 shows the Cisco 7204. Figure 2 shows the
Cisco 7206.
Note The I/O controller is available with or without a Fast Ethernet port. Figure 1 and Figure 2
show an I/O controller with a Fast Ethernet port.

Cisco 7200 Series Overview
The rear of the Cisco 7200 series routers provides access to the network processing engine and up
to two 280W, AC-input or DC-input power supplies (refer to Figure 4).
Figure 4 Cisco 7200 Series Router—Rear View
The network processing engine has no external connectors or LEDs. There are two handles for
removing and installing the network processing engine and two captive installation screws for
securing it to the chassis.
A fully configured Cisco 7200 series router operates with only one installed power supply; however,
a second, optional power supply provides hot-swappable, load-sharing, redundant power. The power
supply has the router’s main power switch and either an AC-input power receptacle, or a hardwired
DC-input power cable (depending on the type of installed power supply). Adjacent to the power
supply bays there is a 10 x 32-inch chassis ground receptacle that provides a chassis ground
connection for ESD equipment or a grounding wire (refer to Figure 4).
Note The Cisco 7200 routers come equipped with either one 280W AC-input or one 280W
DC-input power supply; a second 280W AC-input or DC-input power supply is available for the
router. Figure 4 shows the rear of a Cisco 7200 series router that is configured with a single 280W
AC-input power supply. (A power supply filler plate is installed over the second power supply bay.)
Three internal fans draw cooling air into the chassis interior and across internal components to
maintain an acceptable operating temperature (refer to Figure 4). The three fans are enclosed in a
tray that is located in the subchassis.
The I/O controller, port adapters, power supplies, and network processing engine slide into their
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.

Memory Systems Overview
Memory Systems Overview
The Cisco 7200 series memory systems are divided between the I/O controller and the network
processing engine. The memory systems provide the following functions:
•Main memory (DRAM)—Stores the running configuration and routing tables. The
Cisco Internetwork Operating System (Cisco IOS) software executes from main memory.
•Shared memory—Used for packet buffering by the router’s network interfaces.
•Flash memory SIMM—Stores the boot helper software. The boot helper image allows you to
boot the router when Flash memory does not contain a valid system image.
•Flash memory card(s)—Stores the default Cisco IOS software image.
•Erasable programmable read-only memory (EPROM)-based memory—The ROM monitor
permits you to boot the Cisco IOS image from Flash memory if a boot helper image is not present
in boot Flash memory.
•Nonvolatile random-access memory (NVRAM)—Stores the system configuration,
environmental monitoring logs, and the virtual configuration register.
Table 1 lists the Cisco 7200 series processor and memory specifications. Table 2 lists the network
processing engine factory-installed DRAM configurations and their product numbers. Figure 5
shows the I/O controller with the optional Fast Ethernet port. Figure 6 shows the network processing
engine.

Safety Guidelines
Following are safety guidelines that you should follow when working with any equipment that
connects to electrical power or telephone wiring.
Electrical Equipment Guidelines
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 in which you are working.
•Disconnect all power and external cables before moving a chassis.
•Do not work alone when potentially hazardous conditions exist.
•Never assume that power has been disconnected from a circuit; always check.
H5887
Angled tips

10
Installation Prerequisites
•Do not perform any action that creates a potential hazard to people or makes the equipment
unsafe.
•Carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.
Telephone Wiring Guidelines
Use the following guidelines when working with any equipment that is connected to telephone
wiring or to other network cabling:
•Never install telephone wiring during a lightning storm.
•Never install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
•Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
•Use caution when installing or modifying telephone lines.
Preventing Electrostatic Discharge Damage
Electrostaticdischarge(ESD)damages equipmentand impairs electricalcircuitry. ESD occurswhen
printed circuit boards or memory SIMMs are improperly handled and results in complete or
intermittent failures.
The I/O controller and network processing engine consist of a printed circuit board that is fixed in a
metal carrier. Electromagnetic interference (EMI) shielding, connectors, and a handle are integral
components of the carrier. Handle the I/O controller and network processing engine by their carrier
edges and handle; never touch the printed circuit board or connector pins.
Figure 8 shows the location of a printed circuit board when it is installed in a network processing
engine or I/O controller metal carrier. Do not touch the printed circuit board when handling either
component.
Figure 8 Handling the I/O Controller and the Network Processing Engine
Handle SIMMs by the edges only; avoid touching the memory modules, pins, or traces (the metal
fingers along the connector edge of the SIMM) (refer to Figure 9). Always wear a preventive
antistatic strap whenever handling SIMMs.
