CHAPTER 1
Safety Warnings
This handout lists the safety warnings necessary for handling this chassis. Before you install or service the
chassis, review these safety warnings to avoid injuring yourself or damaging the equipment.
For a complete list of translated safety warnings, see the Regulatory Compliance and Safety Information —
Cisco NCS 500 Series Routers document.
The safety warnings are grouped under the following sections:
•Standard Warning Statements, on page 1
•Safety Guidelines for Personal Safety and Equipment Protection, on page 2
•Safety with Electricity, on page 3
•Cautions and Regulatory Compliance Statements for NEBS, on page 4
•Power Supply Considerations, on page 5
•Preventing ESD Damage, on page 6
Standard Warning Statements
IMPORTANT SAFETY INSTRUCTIONS
This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work
on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard
practices for preventing accidents. Use the statement number provided at the end of each warning to locate
its translation in the translated safety warnings that accompanied this device. Statement 1071
SAVE THESE INSTRUCTIONS
Warning
This unit is intended for installation in restricted access areas. A restricted access area can be accessed only
by using a special tool, lock and key, or other means of security. Statement 1017
Warning
Ultimate disposal of this product must be handled according to all national laws and regulations. Statement
1040
Warning

To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended
ambient temperature of –40C to +65C. Statement 1047
Warning
Mount the device on a rack that is permanently affixed to the building. Statement 1049
Warning
This device is a Class A Device and is registered for EMC requirements for industrial use. You must be aware.
If sold or purchased by mistake, do replace with a residential-use type. Statement 294
Warning
This equipment needs to be grounded. Use a green and yellow 6AWG ground wire to connect the host to earth
ground during normal use. Statement 383
Warning
Do not stare into the beam or view it directly with optical instruments. Statement 1011
Warning
Invisible laser radiation present. Statement 1016
Warning
The plug-socket combination must be accessible at all times, because it serves as the main disconnecting
device. Statement 1019
Warning
SafetyGuidelines forPersonalSafety andEquipmentProtection
The following guidelines ensure your safety and protect the equipment. This list does not include all the
potentially hazardous situations. Therefore, you must be alert.
• Before moving the system, always disconnect all power cords and interface cables.
• Never assume that power is disconnected from a circuit; always check.
• Before and after installation, keep the chassis area clean and dust free.
• Keep tools and assembly components away from walk areas where you or others can trip over them.
• Do not work alone if potentially hazardous conditions exist.
• Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
• Do not wear loose clothing that may get caught in the chassis.
• When working under conditions that may be hazardous to your eyes, wear safety glasses.

Safety Warnings
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
Before working on equipment that is connected to power lines, remove jewelry (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
Read the installation instructions before connecting the system to the power source. Statement 1004
Warning
The plug-socket combination must be accessible always, because it serves as the main disconnecting device.
Statement 1019
Warning
This unit may have more than one power supply connection. All connections must be removed to de-energize
the unit. Statement 1028
Warning
When installing or replacing the unit, ensure the ground connection first and disconnected last. Statement
1046
Warning
This equipment is intended to be grounded to comply with emission and immunity requirements. Ensure that
the switch functional ground lug is connected to earth ground during normal use. Statement 1064
Warning
Installation of the equipment must comply with local and national electrical codes. Statement 1074
Warning
When working on equipment that is powered by electricity, follow these guidelines:

Safety Warnings
Safety with Electricity

• Locate the room’s emergency power-off switch. If an electrical accident occurs, you know where to
quickly turn off the power.
• Before starting work on the system, turn off the DC main circuit breaker and disconnect the power
terminal block cable.
• Disconnect all power when:
• Working on or near power supplies
• Installing or removing a device chassis or network processor module
• Performing most hardware upgrades
• Never install equipment that appears damaged.
•Carefully examine your work area for possible hazards, such as moist floors, ungrounded power extension
cables, and missing safety grounds.
• Never assume that power is disconnected from a circuit; always check.
• Never perform any action that creates a potential hazard to people or makes the equipment unsafe.
• If an electrical accident occurs and you are uninjured:
• Use caution to avoid injuring yourself.
• Turn off power to the device.
• Seek medical attention, if necessary.
Use the following guidelines when working with any equipment that is disconnected from a power source,
but connected to telephone wiring or network cabling:
• When installing or modifying telephone lines, use caution.
• Never install telephone jacks in wet locations unless the jack is designed to handle such locations.
• Never install telephone wiring during a lightning storm.
Cautions and Regulatory Compliance Statements for NEBS
The NEBS-GR-1089-CORE regulatory compliance statements and requirements are discussed in this section.
The intrabuilding port(s) of the equipment or subassembly, which is the management Ethernet port, must use
shielded intrabuilding cabling/wiring that is grounded at both ends. Statement 7003
