THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL
STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT
WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT
SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE
OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required
to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not
installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to
comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable
protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital
devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television
communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its
peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits
controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Safety Guidelines

Before you perform any Cisco NCS 4016 chassis installation procedures, review the safety guidelines in
this section to avoid injuring yourself or damaging the equipment.

Note Review the safety warnings listed in Regulatory Compliance and Safety Information for the Cisco

Network Convergence System 4000 Series before installing, configuring, or troubleshooting any installed

card.

Note Power off the system before removing or installing a power tray.

Chapter 2 Chassis Overview

The following guidelines are for your safety and to protect equipment. The guidelines do not include all
hazards. Be alert.

• Never attempt to lift an object that might be too heavy for you to lift by yourself.

• Keep the work area clear and dust-free during and after installation. Do not allow dirt or debris to

enter into any laser-based components.

• Keep tools and chassis components away from walk areas.

• Do not wear loose clothing, jewelry, and other items that could get caught in the chassis while

working with the chassis and its components.

• Use Cisco equipment in accordance with its specifications and product-usage instructions.

• Do not work alone if potentially hazardous conditions exist.

• Make sure that your installation follows 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, CSA C22.1; in other countries, International Electrotechnical
Commission (IEC) 60364, part 1 through part 7.

• Connect only a DC power source that follows the safety extra-low voltage (SELV) requirements in

UL/CSA/IEC/EN 60950-1 and AS/NZS 60590 to the DC input power system.

• Make sure that you have a readily accessible two-poled disconnect device incorporated in the fixed

configuration wiring of a DC input power system.

• Make sure that you provide short-circuit (overcurrent) protection as part of the building installation.

Cisco Network Convergence System 4000 Series Hardware Installation Guide

Chapter 2 Chassis Overview

Preventing Electrostatic Discharge

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are
improperly handled, results in complete or intermittent failures. We recommend use of an
ESD-preventive wrist strap whenever you handle network equipment or one of its components.

Following are guidelines for preventing ESD damage:

• Always use an ESD-preventive wrist or ankle strap, and ensure that it makes good skin contact.

Connect the equipment end of the connection cord to an ESD jack (Figure 2-8 and Figure 2-9) or a
bare metal surface on the chassis (ensure the chassis is grounded).

• Handle a card by its ejector levers, when applicable, or its metal carrier only; avoid touching the

board or connector pins.

• Place a removed card board side up on an antistatic surface or in a static-shielding bag. If you plan

to return the component to the factory, immediately place it in a static-shielding bag.

• Avoid contact between a card and clothing. The wrist strap protects the board from only ESD voltage

on the body; ESD voltage on clothing can still cause damage.

Figure 2-8 shows the ESD jacks on the top of the chassis.
