safety:
•Keep the chassis area clear and dust-free during and after installation.
•Put the removed chassis cover in a safe place.
Warning The safety cover is an integral part of the product. Do not operate the unit without the
safety cover installed. Operating the unit without the cover in place will invalidate the safety
approvals and pose a risk of fire and electrical hazards.
•Keep tools away from walk areas where you and others could fall over them.
•Do not wear loose clothing, jewelry (including rings and chains), or other items that could get
caught in the chassis. Fasten your tie or scarf and roll up your sleeves.
•Wear safety glasses if you are working under any conditions that might be hazardous to your
eyes.
•Do not perform any action that creates a potential hazard to people or makes the equipment
unsafe.
•The installation of the router 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 Canada, Canadian Electrical Code, part I, CC22.1. In other countries,
International Electrotechnical Commission (IEC) 364, part 1 through part 7.
•Never attempt to lift an object that might be too heavy for you to lift by yourself.
•Always power off (O) the power supplies and unplug all power cables before opening the chassis.
•Always unplug the power cable before installing or removing a chassis.
•The AC-powered routers ship with a three-wire electrical grounding-type plug, which only fits
into a grounding-type power outlet. This is a safety feature. The equipment grounding should be
in accordance with local and national electrical codes.
•The routers operate safely when used in accordance with their marked electrical ratings and
product usage instructions.
Warning Ultimate disposal of this product should be handled according to all national laws and
regulations.

Electrical Equipment Guidelines
Electrical Equipment Guidelines
Warning Before working on equipment that is connected to power lines, remove jewelry (including
rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and
can cause serious burns or can weld the metal object to the terminals.
Warning This unit might have more than one power supply connection. All connections need to be
removed to de-energize the unit.
Follow these guidelines when you work on equipment powered by electricity.
•Locate the emergency power-off switch for the room in which you are working. Then, if an
electrical accident occurs, you can act quickly to power off the equipment.
•Before working on the system, unplug the power cord.
•Disconnect all power before doing the following:
—Installing or removing a chassis
—Working near power supplies
Warning This equipment is intended to be grounded. Ensure that the host is connected to earth
ground during normal use.
Warning When installing the unit, the ground connection must always be made first and
disconnected last.
•Do not work alone if potentially hazardous conditions exist.
•Never assume that power is disconnected from a circuit. Always check.
•Look carefully for possible hazards in your work area, such as moist floors, ungrounded power
extension cables, frayed power cords, and missing safety grounds.
•If an electrical accident occurs, proceed as follows:
—Use caution; do not become a victim yourself.
—Power off the system.
—If possible, send another person to get medical aid. Otherwise, assess the condition of the
victim and then call for help.
—Determine if the person needs rescue breathing or external cardiac compressions; then take
appropriate action.
Warning This product relies on the building’s installation for short-circuit (overcurrent) protection.
Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international)
is used on the phase conductors (all current-carrying conductors).
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.
•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.

Safety Recommendations
Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord.
Electrostatic Discharge Prevention
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage
occurs when electronic components are improperly handled and can result in complete or
intermittent failures.
Always follow ESD-prevention procedures when you remove and replace components. Ensure that
the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring
that it makes good skin contact. Connect the grounding clip to an unpainted surface of the chassis
frame to safely ground unwanted ESD voltages. To guard against ESD damage and shocks, the wrist
strap and cord must operate properly. If no wrist strap is available, ground yourself by touching the
metal part of the chassis.
Caution For safety, periodically check the resistance value of the antistatic strap, which should be
between 1 and 10 megohms (Mohm).
Figure 1 Attaching an Electrostatic Discharge Wrist Strap
Chassis Lifting Guidelines
A fully configured Cisco 7100 series router weighs approximately 32 pounds (14.5 kg). The chassis
is not intended to be moved frequently. Before you install the router, ensure that your site is properly
prepared so you can avoid having to move the chassis later to accommodate power sources and
network connections.
Whenever you lift the chassis or any heavy object, follow these guidelines:
•Always disconnect all external cables before lifting or moving the chassis.
•Ensure that your footing is solid, and balance the weight of the object between your feet.
•Lift the chassis slowly; never move suddenly or twist your body as you lift.
•Keep your back straight and lift with your legs, 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.
Warning To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis
using the handles on the port adapters; these types of handles are not designed to support the weight
of the unit. Lift the unit only by grasping the chassis underneath its lower edge.

Site Requirement Guidelines
Site Requirement Guidelines
Warning This unit is intended for installation in restricted access areas. A restricted access area is
where access can only be gained by service personnel through the use of a special tool, lock and key,
or other means of security, and is controlled by the authority responsible for the location.
The environmental monitoring functionality in the router 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 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.
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.
•Keep the router 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 port adapters and any blank port adapters are in place and secure. The fans direct
cooling air throughout the chassis interior; a loose component or empty slot can redirect the
airflow away from active components.
Rack-Mounting Guidelines
The rack-mounting hardware included with router is suitable for most 19- or 23-inch equipment
racks and telco-type racks. To easily access the interface cables while the router is installed in a rack,
make certain you have access to the 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 the router in the rack, and then replace it after the chassis is installed.
As an alternative, you can mount the 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 the router. Figure 2 shows the Cisco 7100 series
router footprint and outer dimensions.
To use the rack-mounting hardware provided with the router, 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 inches (43.18 cm).
•The height of the chassis is 3.5 inches (8.89 cm).
•When mounting the router in four-post or telco-type racks, be sure to use all the screws and the
brackets provided to secure the chassis to the rack posts.

Safety Recommendations
Figure 2 Cisco 7100 Series Router Footprint and Outer Dimensions
When planning your rack installation, consider the following guidelines:
•Install the router in an open rack whenever possible. If installation in an enclosed rack is
unavoidable, ensure that the rack has adequate ventilation.
Caution To prevent chassis overheating, never install the router in an enclosed rack or room that
is not properly ventilated or air conditioned.
•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 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 7100 series routers.
•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 a port adapter or connecting cables). Otherwise, allow 19 inches (48.3 cm) of clearance
to remove a port adapter.

Power Connection Guidelines
•Maintain a minimum clearance of 3 inches (7.62 cm) on the back and front of the chassis for the
cooling air inlet and exhaust ports, respectively. Avoid placing the router 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 half of a rack to maintain a low center of gravity
and prevent the rack from falling over.
•If you use telco-type racks, be sure that the rack is bolted to the floor and secured because 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 does not make the rack unstable.
•Provide an adequate chassis ground (earth) connection for your router chassis.
Note We strongly recommend that you provide a chassis ground connection. Refer to Chapter 2,
“Preparing for Installation,” in the Cisco 7100 Series VPN Router Installation and Configuration
Guide for chassis grounding instructions.
Power Connection Guidelines
Follow these precautions and recommendations when planning power connections to a Cisco 7100
series 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.
•The AC power supply includes the following features:
—Autoselects either 110V or 220V operation.
—All units include a 6-foot (1.8-meter) electrical power cord. (A label near the power cord
indicates the correct voltage, frequency, current draw, and power dissipation for the unit.)
Warning This product relies on the building’s installation for short-circuit (overcurrent) protection.
Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international)
is used on the phase conductors (all current-carrying conductors).
•Install proper grounding to avoid damage from lightning and power surges.
Warning Never defeat the ground conductor or operate the equipment in the absence of a suitably
installed ground conductor. Contact the appropriate electrical inspection authority or an electrician
if you are uncertain that suitable grounding is available.
Note The Cisco 7100 series 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 chassis employs two threaded 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 M3.5 screws, which are included. (For instructions on how
to properly ground the chassis, refer to Chapter 3, “Installing Cisco 7100 Series Routers” in the
Cisco 7100 Series VPN Router Installation and Configuration Guide.

8Installing Field-Replaceable Units in Cisco 7100 Series VPN Routers
Installing the Rack-Mount and Cable-Management Brackets
•The AC-input power supply uses a power factor corrector that allows the router to operate on
input voltage and frequency within the ranges of 100 to 240 VAC and 50/60 Hz.
Note We recommend an uninterruptible power source to protect against power failures at your
site. We recommend powering a Cisco 7100 series router from a 15A receptacle at the power
source.
Installing the Rack-Mount and Cable-Management Brackets
The rack-mount and cable-management kit for the Cisco 7100 series routers consists of rack-mount
brackets and a cable-management bracket that are designed for mounting your router in 19- or
23-inch, 4-post or telco-type equipment racks.
This section describes how to attach the rack-mount and cable-management brackets to the router.
For more information about cabling the router, refer to Chapter 3, “Installing Cisco 7100 Series
Routers” in the Cisco 7100 Series VPN Router Installation and Configuration Guide.
Attaching the Cable-Management Bracket
To install the cable-management bracket on the router, complete the following steps:
Step 1 Locate the chassis grounding receptacles on the rear sides of the chassis. (See Figure 3.)
Note Both rear sides of Cisco 7100 series chassis have two grounding receptacles.
Attach the cable-management bracket to the two grounding receptacles that were not used
to ground the chassis. Refer to Chapter 2, “Preparing for Installation,” in the Cisco 7100
Series VPN Router Installation and Configuration Guide for chassis grounding
instructions.
Step 2 Align the cable-management bracket to the vacant receptacles. Ensure the two flanges on
the bracket are facing away from the chassis.
Step 3 Thread two M3.5 x 7-mm slotted hexhead screws through the bracket and into the chassis.
Use a flat-blade screwdriver to tighten the screws. Use tie wraps to secure interface cables
to the bracket flanges.

Replacing SDRAM DIMMs
This section describes how to replace the SDRAM DIMMs in the router. You might need to upgrade
the SDRAM DIMMs for the following reasons:
•You have upgraded to a new Cisco IOS feature set or release that requires more memory.
•You are using very large routing tables or many protocols (for example, when the router is set up
as a connection device between large external networks and your internal network).
The network processor card contains three sockets for SDRAM DIMMs (see Figure 9):
•Socket DIMM 1 and socket DIMM 2 hold system and packet memory SDRAM DIMMs. System
memory is used by the CPU to store the operating configuration, routing tables, caches, and
queues. The DIMMs can be 64 MB or 128 MB, and the capacity of the DIMM in slot DIMM 1
must be greater than or equal to the capacity of the DIMM in slot DIMM 2.
•Socket DIMM 0 holds a packet memory SDRAM DIMM. Packet memory is used to store
incoming and outgoing packets. This DIMM is fixed at 64 MB.
