General Safety Guidelines for Personal Safety and Equipment

Protection

Follow these safety guidelines:

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

• Always unplug power cables when performing maintenance or working on the chassis, unless the

replacement part is hot swappable and designed for online insertion and removal (OIR).

• Keep the work area clear and dust free during and after installation.

• Keep tools and chassis components away from walkways and equipment rack aisles.

• Do not wear loose clothing, jewelry (including rings and chains), or other items that could get caught in

the equipment.

• Fasten your tie or scarf and sleeves.

• Operate Cisco equipment safely by using it in accordance with its electrical ratings and product usage

instructions.

• Do not work alone if potentially hazardous conditions exist.

• Ensure that the installation of the router is 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, CSA C22.1; in other countries, International Electrotechnical

Commission (IEC) 364, part 1 through part 7.

Safety Precaution for Module Installation and Removal

Ensure to observe the following safety precautions when you are working with the chassis modules.

Invisible laser radiations present.Statement 1016

Warning

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams

or view directly with optical instruments.Statement 1051

General Safety Guidelines for Personal Safety and Equipment Protection

Safety with Electricity

Before working on a chassis or with power supplies, unplug the power cord on AC units. Disconnect

the power at the circuit breaker on DC units.Statement 12

Warning

Beforeworkingonequipmentthatisconnectedtopowerlines,removejewelry(including rings, necklaces,

and watches). Metal objects heat up when connected to power and ground and can cause serious burns

or weld the metal object to the terminals.Statement 43

Warning

Avoid using or servicing any equipment that has outdoor connections during an electrical storm. There

may be a risk of electric shock from lightning. Statement 1088

Warning

This equipment must be grounded. 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.Statement 1024

Warning

This unit may have more than one power supply connection. All connections must be removed to

de-energize the unit.Statement 1028

Warning

Wheninstalling or replacingthe unit,ensurethe ground connection firstand disconnected last. Statement

1046

Warning

Thisequipment is intended to be groundedtocomply with emission and immunity requirements.Ensure

that the switch functional ground lug is connected to earth ground during normal use. Statement 1064

Warning

Power Connection Guidelines

Check the power at your site to ensure you are receiving clean power (free of spikes and noise).

Ensure to observe the following safety guidelines while connecting the device power supplies.

Safety Guidelines

Safety with Electricity

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. Statement 1024

Warning

Use copper conductors only. Statement 1025

Warning

This product requires short-circuit (overcurrent) protection, to be provided as part of the building

installation. Install only in accordance with national and local wiring regulations. Statement 1045

Warning

Safety Precaution for Energy Hazard

Do not reach into a vacant slot when installing or removing a module. Exposed circuitry is an energy

hazard.Statement 206

Warning

The Cisco NCS 1004 can be configured for a DC power source. Do not touch terminals with body parts or

conductive objects while they are energized.

Safety Precaution for Laser Radiation

Cisco NCS 1004 is classified as Hazard Level 1M as per IEC 60825-2 and Laser Class 1/1M as per IEC

60825-1, since it may include Class 1 or Class 1M Laser sources.

Warning

Invisible laser radiations present.Statement 1016

Warning

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams

or view directly with optical instruments.Statement 1051

Warning

Prevent Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD may occur when

electronic printed circuit cards are improperly handled and can cause complete or intermittent failures. When

removing and replacing modules, always follow these ESD prevention procedures:

• Ensure that the device chassis is electrically connected to earth ground.

• Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact.

• Handle components by only their handles or edges; do not touch the printed circuit boards or connectors.

• Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components

from ESD voltages on the body; ESD voltages on clothing can still cause damage.

Prevent Electrostatic Discharge Damage

NEBS Regulatory Compliance Statements

The NEBS-GR-1089-CORE regulatory compliance statements and requirements are discussed in this section.

The intra-building port(s) (Management Ethernet Ports) of the equipment or subassembly must use

shielded intra-building cabling/wiring that is grounded at both ends. Statement 7003

Warning

The intra-building port(s) (Management Ethernet Ports) of the equipment or subassembly is suitable

for connection to intra-building or unexposed wiring or cabling only. The intra-building port(s) of the

equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or

its wiring for more than 6 meters (approximately 20 feet). These interfaces are designed for use as

intra-building interfaces only (Type 2, 4, or 4a ports as described in GR-1089) and require isolation

from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order

to connect these interfaces metallically to an OSP wiring system. Statement 7005

Warning

Productsthat haveACpowerports that areintendedfordeployments wherean externalSurgeProtective

Device (SPD) is utilized at the AC power service equipment (see definition in National Electric Code).

Statement 7012

This product is designed for a Common Bonding Network (CBN) installation. Statement 7013

This product can be installed in network telecommunication facilities or locations where the National

Electric Code applies. Statement 8015 and 8016

The DC return connection to this system should remain isolated from the system frame and chassis

(DC-I). Statement 7016
