Chapter 2 Preparing for Installation
Electrical Equipment Guidelines
•Four M4 x 8-mm Phillips flathead screws to secure the rack-mount brackets to the chassis
•Six 10-32 x 3/8-inch slotted binderhead screws to secure the rack-mount brackets to the rack rails
•Two cable-management brackets to relieve the strain on installed port adapter interface cables
•Four M4 x 8-mm Phillips flathead screws to secure the cable-management brackets to the chassis or
the rack-mount brackets
•Two cable-management brackets for the NPE-G1 or NPE-G2
In addition, you might need the following external equipment:
•One optical cable-management bracket for the NPE-G1 or NPE-G2
•One RJ-45 cable to connect to the Fast Ethernet Management Port on the NPE-G2
•Data service unit (DSU) to connect each serial port to an external network
•One serial port adapter cable for each serial port to connect the port with the remote device or
network
•T1 channel service unit/data service unit (CSU/DSU) that converts the High-Level Data Link
Control (HDLC) synchronous serial data stream into a T1 data stream with the correct framing and
ones density to connect a serial port to a T1 network. (Some telephone systems require a minimum
number of 1 bits per time unit in a data stream, called ones density.) Several T1 CSU/DSU devices
are available as additional equipment, and most provide either a V.35, EIA/TIA-449, or EIA-530
electrical interface.
•Ethernet transceiver
•Token Ring multistation access unit (MSAU)
Electrical Equipment Guidelines
The port adapters and power supplies are designed to be removed and replaced while the system is
operating without presenting an electrical hazard or damage to the system. However, you must power
down the system before removing or replacing the I/O controller, Port Adapter Jacket Card, and network
services engine (NSE) or network processing engine (NPE).
Caution Always tighten the captive installation screws on the network processing engine or network services
engine and I/O controller. These screws prevent accidental removal, provide proper grounding for the
system, and help ensure that the bus connectors are properly seated in the midplane.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which occurs when electronic cards or components are
improperly handled, can result in complete or intermittent system failures. The network processing
engine or network services engine, I/O controller, and each port adapter consists 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. Although the carrier helps protect the boards, use an
antistatic strap whenever handling the network processing engine or network services engine, I/O
controller, and port adapters. Handle the carriers by the handle and the carrier edges only; never touch
the boards or connector pins.

Site Requirement Guidelines
The environmental monitoring functionality in the Cisco 7200 VXR routers protects the system and
components from potential damage from overvoltage and overtemperature conditions. To ensure normal
operation and avoid unnecessary maintenance, plan your site configuration and 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.
Planning a proper location for the Cisco 7200 VXR router and the layout of your equipment rack or
wiring closet is 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 installation and ongoing operation.
When you plan the location and layout of your equipment rack or wiring closet, you need to consider
how air flows through your router. The Cisco 7200 VXR routers draw cooling air in through the intake
vent on the right side of the chassis (when you view the router from the front), and move the air across
the internal components and out the exhaust vent on the left side of the chassis.
Temperature sensors on the network processing engine or network services engine and I/O controller
monitor the internal air temperature and send warning messages when the internal air temperature
approaches a specified threshold. If the internal temperature exceeds the specified threshold, the system
environmental monitor shuts down all internal power to prevent equipment damage from excessive heat.
(See the “Environmental Monitoring and Reporting Functions” section on page 1-59 for temperature
threshold information.)
Figure 2-1 shows the airflow through the router.

Chapter 2 Preparing for Installation
Site Requirement Guidelines
Figure 2-1 Internal Airflow—Top View
The left and right sides of the chassis must remain unobstructed to ensure adequate air flow and prevent
overheating inside the chassis; we recommend at least 3 in. (7.62 cm) of clearance.
Follow these general precautions when planning your equipment locations and connections:
•Use the show environment command regularly to check the internal system status. The
environmental monitor continually checks the interior chassis environment; it provides warnings for
high temperature and maximum and minimum voltages and creates reports on any occurrences. If
warning messages are displayed, take immediate action to identify the cause and correct the
problem.
•We recommend keeping Cisco 7200 VXR routers off the floor and out of any area that tends to
collect dust.
•Follow ESD prevention procedures to avoid damage to equipment. Damage from static discharge
can cause immediate or intermittent equipment failure.
•Ensure that the network processing engine or network services engine, I/O controller, port adapters,
any blank port adapters, Port Adapter Jacket Card, power supplies, and any power supply filler
plates are in place and secure. The fans direct cooling air throughout the chassis interior; a loose
component or empty slot can redirect the air flow away from active components.

Chapter 2 Preparing for Installation
Site Requirement Guidelines
Rack-Mounting Guidelines
Before installing the Cisco 7200 VXR router in a rack, read the “Site Preparation and Safety” section of
the Regulatory Compliance and Safety Information for Cisco 7200 Series Routers to familiarize yourself
with proper site and environmental conditions. Failure to read and follow the guidelines could lead to an
unsuccessful installation and possible damage to the router and components.
The rack-mounting hardware included with Cisco 7200 VXR routers is suitable for most 19-inch
equipment racks and two-post racks. To easily access FRUs while the router is installed in a rack, make
certain you have access to the front and rear of the router.
Before using a particular rack, check for obstructions (such as a power strip) that could impair
rack-mount installation. If a power strip does impair a rear rack-mount installation, remove the power
strip before installing a Cisco 7200 VXR router in the rack, and then replace it after the chassis is
installed. As an alternative, you can mount a Cisco 7200 VXR router on an equipment shelf provided
that the rack dimensions allow you to secure the router to the shelf, and the overall configuration permits
safe installation and access. However, we recommend rack-mounting Cisco 7200 VXR routers.
Figure 2-2 shows the Cisco 7200 VXR router footprint and outer dimensions.
To use the rack-mounting hardware provided with the Cisco 7200 VXR routers, consider the following
guidelines:
•To mount the router between two posts or rails using the brackets, the inner clearance (the width
between the inner sides of the two posts or rails) must be at least 17.00 inches (43.18 cm).
•The height of the chassis is 5.25 inches (13.34 cm).
•When mounting the router in either four-post or two-post racks, be sure to use all the screws and the
brackets provided to secure the chassis to the rack posts.

Chapter 2 Preparing for Installation
Site Requirement Guidelines
When planning your rack installation, consider the following guidelines:
•If you plan to use an equipment shelf, ensure that the shelf is constructed to support the weight and
dimensions of the chassis. Figure 2-2 shows the chassis footprint, which you need if you are
designing a customized shelf. We recommend that you use the rack-mount kit designed for
Cisco 7200 VXR routers.
Caution To prevent chassis overheating, never install the Cisco 7200 VXR in an enclosed rack or room that is not
properly ventilated or air-conditioned.
•Allow sufficient clearance around the rack for maintenance. If the rack is mobile, you can push it
back near a wall or cabinet for normal operation and pull it out for maintenance (installing or moving
port adapters, connecting cables, or replacing or upgrading components). Otherwise, allow 19
inches (48.3 cm) of clearance to remove Cisco 7200 VXR FRUs.
•If you are planning to install the cable-management brackets on a Cisco 7200 VXR router that you
are rack-mounting from the front, you must install the cable-management brackets and the
rack-mount brackets before you install the chassis in the rack.
•Provide an adequate chassis ground (earth) connection for your router chassis.
Note We strongly recommend that you provide a chassis ground connection. See the “Attaching a Chassis
Ground Connection” section on page 3-17 in Chapter 3, “Installing a Cisco 7200 VXR Router” for
instructions.
To properly install a Cisco 7200 VXR chassis in a rack, see the instructions in the “Rack-Mounting a
Cisco 7200 VXR Router” section on page 3-2 in Chapter 3, “Installing a Cisco 7200 VXR Router.”
Temperature and Humidity Requirements
Table 2-1 lists the operating and nonoperating environmental site requirements. The ranges listed are
those within which the Cisco 7200 VXR routers continue to operate; however, a measurement 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.

Chapter 2 Preparing for Installation
Site Requirement Guidelines
Power Connection Guidelines
Follow these precautions and recommendations when planning power connections to a Cisco 7200 VXR
router:
•Check the power at your site before installation and periodically after installation to ensure that you
are receiving clean power. Install a power conditioner if necessary.
•Install proper grounding to avoid damage from lightning and power surges.
Note The Cisco 7200 VXR router installation must comply with all applicable codes and is approved for use
with copper conductors only. The ground bond fastening hardware should be of compatible material and
preclude loosening, deterioration, and electrochemical corrosion of hardware and joined material.
Attachment of the chassis ground to a central office or other interior ground system should be made with
a 6-AWG, copper ground conductor at a minimum.
The Cisco 7200 VXR chassis employs two threaded M5 chassis grounding receptacles, located on the
rear of the chassis, which are intended to be bonded directly to the central offices or other interior ground
system. The chassis ground requires M5 screws and locking hardware, which are not included. (For
instructions on how to properly ground the chassis, see the “Attaching a Chassis Ground Connection”
section on page 3-17 in Chapter 3, “Installing a Cisco 7200 VXR Router.”)
Plant Wiring Guidelines
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.
Interference Considerations
When wires are run for any significant distance in an electromagnetic field, interference can occur
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, especially when it is caused by lightning or radio transmitters, can destroy the signal
drivers and receivers in the Cisco 7200 VXR routers, and can even create an electrical hazard by
conducting power surges through lines and into equipment.
Note To predict and remedy strong EMI, you may also need to consult experts in radio frequency 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.

2-9
Cisco 7200 VXR Installation and Configuration Guide
OL-5013-09
Chapter 2 Preparing for Installation
Initial Configuration Information
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 caused by lightning or other
high-energy phenomena can easily load 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.
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 recommended maximum rate for V.35 is 2 Mbps, but it is commonly used at 4 Mbps
without any problems. If you understand the electrical problems that might arise and can compensate for
them, you should get good results with rates and distances greater than those shown 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 connections to a Cisco 7200 VXR router, you must consider a
number of factors related to each type of interface:
•The type of cabling required for each type (fiber, thick or thin coaxial, shielded twisted-pair, or
unshielded twisted-pair cabling)
•Distance limitations for each signal type
•The specific cables you need to connect each interface
•Any additional interface equipment you need, such as transceivers, hubs, switches, modems,
channel service units (CSUs), or data service units (DSUs)
•Cable pinouts if you plan to build your cables
The specific interface information you need is contained in the documentation that is shipped with each
port adapter. For example, if you need ATM distance limitations and pinouts, refer to the PA-A3
Enhanced ATM Port Adapter Installation and Configuration document. This document is online on
Cisco.com and on the Documentation DVD.
Before installing a Cisco 7200 VXR router, have all additional external equipment and cables on hand.
For ordering information, contact a customer service representative.
Initial Configuration Information
After you install the chassis and verify that all the hardware is operating properly, you must configure
the system and individual interfaces before you can connect your system to external networks. You can
use the setup facility or standard configuration commands to enter the configuration information.
Before you begin, you should be prepared with global (system-wide) parameters such as host names,
passwords, and routing protocols, and configuration information for each interface such as addresses,
rates or speeds of operation, routing protocol specifics, and so on.

Cisco 7200 VXR Router Installation Checklist
Following is some of the information you are likely to need, depending on your configuration:
•Host name for the router
•Passwords to prevent unauthorized privileged-level access to the EXEC command interpreter and
for individual virtual terminal lines
•Protocols you plan to route
•Bridging configuration (if you plan to use bridging and, if so, on which interfaces)
•Internet Protocol (IP) addresses and subnet masks if you are routing IP
•Zone names, network numbers, or node numbers for the new interfaces if required
•Operating speeds for specific interfaces—for example, Token Ring interfaces operate at either
4 or 16 Mbps, and serial interfaces operate at speeds of up to 2 Mbps. The speed of an interface
often depends on the speed of the remote device to which it is attached.
For complete configuration instructions, refer to the Configuration Fundamentals Configuration Guide
and the Configuration Fundamentals Command Reference, which are available on Cisco.com or on the
Documentation DVD.
