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

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.

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
