Statement 1071—Warning Definition
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.

Safety Guidelines
Before you perform any procedure in this document, review the safety guidelines in this section to avoid
injuring yourself or damaging the equipment. The following guidelines are for your safety and to protect the
equipment. Because the guidelines do not include all hazards, be constantly alert.
Cisco Nexus 9808 NX-OS Mode Switch Hardware Installation Guide
7

• Keep the work area clear, smoke and dust-free during and after installation. Do not allow dirt or debris
to enter into any laser-based components.
• Do not wear loose clothing, jewelry, or other items that could get caught in the switch or other associated
components.
• Cisco equipment operates safely when used in accordance with its specifications and product-usage
instructions.
•Be sure to power down a fixed configuration PDU or modular configuration power shelf before removing
it from the chassis.
• If potentially hazardous conditions exist, do not work alone.
• Take care when connecting multiple units to the supply circuit so that wiring is not overloaded.
• 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 about whether suitable grounding is available.
• When installing or replacing the unit, the ground connection must always be made first and disconnected
last.
• To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the
handles on modules (such as power supplies, fans, or cards); these types of handles are not designed to
support the weight of the unit.
• Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when
servicing.
• The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before you slide
out the unit for servicing. Failure to stabilize the rack may cause the rack to tip over.
Compliance and Safety Information
The Cisco Nexus 9800 Series Switches are designed to meet the regulatory compliance and safety approval
requirements. For detailed safety information, see Regulatory Compliance and Safety Information.
Statement 1005—Circuit Breaker
This product relies on the building's installation for short-circuit (overcurrent) protection.
•Ensure that the protective devices are rated not greater than 30A max (North America); 32A max (Europe);
32A max (UK) (AC/HVAC/HVDC) (AHF-2DC-6300W), 100A max (LVDC) (DHF-2DC-4400W).

Prepare for Installation
Compliance and Safety Information

Laser Safety
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or
view directly with optical instruments.
Warning
Invisible laser radiation is present. Do not expose to users of telescopic optics. This applies to Class 1/1M
laser products.
Warning
Pluggable optical modules comply with IEC 60825-1 Ed. 3 and 21 CFR 1040.10 and 1040.11 with or without
exception for conformance with IEC 60825-1 Ed. 3 as described in Laser Notice No. 56, dated May 8, 2019.
Warning
Energy Hazard
The switch can be configured for a DC power source. Do not touch terminals while they are live. Observe
the following warning to prevent injury.
Statement 1086—Power Terminals
Hazardous voltage or energy may be present on power terminals. Always replace cover when terminals are
not in service. Be sure uninsulated conductors are not accessible when cover is in place.
Warning
Preventing Electrostatic Discharge Damage
Many components can be damaged by static electricity. Not exercising the proper electrostatic discharge
(ESD) precautions can result in intermittent or complete component failures. To minimize the potential for
ESD damage, always use an ESD-preventive antistatic wrist strap (or ankle strap) and ensure that it makes
adequate skin contact.
Check the resistance value of the ESD-preventive strap periodically. The measurement should be 1–10
megohms.
Note
Before you perform any of the procedures in this guide, attach an ESD-preventive strap to your wrist and
connect the leash to the chassis.

Laser Safety

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
Warning
The intrabuilding port(s) of the equipment or subassembly, which is the management Ethernet port, must not
be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed
for use as intrabuilding interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE) 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 OSP wiring. Statement 7005
Warning
This equipment shall be connected to AC mains provided with a surge protective device (SPD) at the service
equipment complying with NFPA 70, the National Electrical Code (NEC). Statement 7012
Warning
This equipment is suitable for installations utilizing the Common Bonding Network (CBN). Statement 7013
Warning
The battery return conductor of this equipment shall be treated as (DC-I). Statement 7016
Warning
This equipment is suitable for installation in Network Telecommunications Facilities. Statement 8015
Warning
This equipment is suitable for installation in locations where the NEC applies. Statement 8016
Warning
Installation Guidelines
Before installing the chassis, ensure that the following guidelines are met:
• Site is properly prepared so that there is sufficient room for installation and maintenance.
• Operating environment is within the ranges that are listed in Environment and Physical specifications.
For more details on environmental requirements, see Cisco Nexus 9800 Series Switches Data Sheet.
• Chassis is mounted at the bottom of the rack if it is the only unit in the rack.
Cisco Nexus 9808 NX-OS Mode Switch Hardware Installation Guide
10
Prepare for Installation
Cautions and Regulatory Compliance Statements for NEBS

• When mounting the chassis in a partially filled rack, load the rack from the bottom to the top with the
heaviest component at the bottom of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the
chassis in the rack.
• Airflow around the chassis and through the vents is unrestricted.
• Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting
fixtures. Make sure that the cabling is safely away from other devices that might damage the cables.
• Each port must match the wave-length specifications on each end of the cable, and the cable must not
exceed the stipulated cable length.
Cisco 9800 Series switches function in operating temperatures of up to 40°C at sea level. For every 300 meters
(1000 ft) elevation upto 1800 meters (6000 ft), the maximum temperature is reduced by 1°C. For more details
on environmental requirements, see Cisco Nexus 9800 Series Switches Data Sheet.
Note
Procure Tools and Equipment
Obtain these necessary tools and equipment for installing the chassis:
• Number 1 and number 2 Phillips screwdrivers with torque capability to rack-mount the chassis.
• 3/16-inch flat-blade screwdriver.
• Tape measure and level.
• ESD wrist strap or other grounding device.
• Antistatic mat or antistatic foam.
• Two-hole ground lug (1).
•Grounding cable (2 AWG recommended), sized according to local and national installation requirements;
the required length depends on the proximity of the switch to proper grounding facilities.
• A crimping tool specified by the lug manufacturer that is large enough to accommodate the girth of the
lug.
• Wire-stripping tool.
• A maximum of 70 rack mount screws can be used based on your rack selection.
