Cisco 7200 Series Overview
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.

Port Adapters
Port Adapters The following sections provide international agency compliance, safety, and statutory information
for specific port adapters that are used in the Cisco 7204 and Cisco 7206 routers.
PA-4T Synchronous Serial Port Adapter
The Cisco Systems 4T port adapter (Part Number 73-1185) is used in Cisco 7200 series routers and
is supplied by Cisco Systems Europe. The 4T port adapter provides the hardware necessary to
connect Cisco 7200 series routers to digital leased line circuits (point to point) and to Packet
Switched Public Data Networks (PSPDN).
The 4T port adapter has up to four synchronous serial interfaces. Each interface provides a
connection to leased lines on packed switched services of the type X.21, V.24, V.35, and V.36.
Wide-area network (WAN) operating software for the 4T port adapter is bundled with the Cisco IOS
software image that is running on the Cisco 7200 series router.
Each interface on the 4T port adapter is a custom 60-way connector. The following interface
configurations are supported:
•X.21 interface for connecting to leased lines at up to 2048 kbps or X.25 packet-switched service
at up to 2 Mbps
•X.24 interface for connecting to X.21bis leased lines or X.25 packet-switched service at up to
19.2 kbps
•V.35 interface for connecting to X.21bis leased lines or X.25 packet-switched service at up to 64
kbps
•V.36 interface for connecting to X.25 packet-switched service at up to 64 kbps
The configuration of an interface depends on the serial port adapter cable attached to the interface.
The 4T port adapter incorporates cable sensing circuitry to detect the presence of a specific cable for
each service. Further configuration is not necessary. The following Cisco cables are available for the
4T port adapter:
•X.21 DTE adapter cable (Part Number 72-0789)
•X.21 DCE adapter cable (Part Number 72-0790)
•V.35 DTE adapter cable (Part Number 72-0791 and 72-0801)

Port Adapters
X.25 Support X.25 packet-switched support is provided by the operating software that is bundled with the
Cisco IOS software image. The operating software provides both the link and packet level facilities
of the 4T port adapter.
The operating software is accessed via a VT100 terminal connected to the console port of the
Input/Output controller. The settings of the terminal should be as follows:
•Baud: 9600
•Data bits: 8
•Parity: none
•Stop bits: 1
To boot the software, type the following command at the “>” prompt:
> b flash
(The software will now boot from Flash memory.)
Safety Information Following are safety instructions for installing the 4T port adapter in a Cisco 7200 series router.
Failure to install the 4T port adapter in accordance with these instructions will invalidate the
approval.
•The 4T port adapter contains Safety Extra-Low Voltage (SELV) circuitry. Ensure that
attachments at the interconnection ports of the apparatus are also SELV circuits. (SELV circuits
are so designed and protected that, under both normal conditions and a likely fault condition, the
voltage that can be drawn is not hazardous.)
•Always disconnect the chassis from the power supply before removing any covers.
•Always disconnect the host product chassis from any analogue telephone circuits or ISDN
(where applicable) before removing any covers.
If you have any doubt as to how to safely install the 4T port adapter correctly in a Cisco 7200 series
router, please seek advice from a qualified telecommunications engineer.
Power Requirements
The power requirements of the 4T port adapter are as follows:
•+5 VDC/2000mA
•+12 VDC/120mA
•–12 VDC/120mA
It is important to ensure that the power drawn by the apparatus, together with any auxiliary
apparatus, lies within the rating of the host power supply.
Approvals The 4T port adapter has received approval from Nihon Cisco Systems K.K. of Japan. The approval
number is N96-K058-0.

Installation Requirements
This section describes special installation requirements for the 4T port adapter.
Where applicable, the 4T port adapter is approved only for installation in a host and with host
attachments, which are either typeapprovedfor such apparatus or covered by a General Approval.
Except at the edge connector, which plugs into the router’s midplane, clearance and creepage
distances of X millimeters (mm) and Y mm, as listed in Table 1, must be maintained between the 4T
port adapter and other parts of the host, including any other port adapters.
Creepage distance is defined as the minimum distance between two points (following the contour of
the insulator) measured across the surface of an insulator. Clearance distance is defined as the
minimum distance between two points (line of sight) measured in air.
Table 1 Creepage and Clearance Distances Based on Voltage
Clearance and creepage distances are measured between adjacent parts, as shown in Figure 5.
Figure 5 Creepage and Clearance Distance Measurements
1. Vrms = root mean square voltage.
2. VDC = volts direct current.
3. The creepage distances not in parentheses apply when the equipment is installed in a normal office environment. The larger
dimensions, given in parentheses, must be applied when the equipment is installed in an environment in which dust and other
types of pollution could conduct electricity because of the effects of dampness and condensation. This applies to locations
subject to high humidity.
4. For working voltages exceeding 300V, consult a competent telecommunications engineer prior to installation.
