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.

• 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 router 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.

The Cisco 8000 Series Routers are designed to meet the regulatory compliance and safety approval requirements. For detailed safety information, see Regulatory Compliance and Safety Information—Cisco 8000 Series Routers.

Statement 1029—Blank Faceplates and Cover Panels Blank faceplates and cover panels serve three important functions: they reduce the risk of electric shock and fire, they contain electromagnetic interference (EMI) that might disrupt other equipment, and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.

The routers can be configured for a DC power source. Do not touch terminals while they are live. Observe the following warning to prevent injury.

Warning

Statement 1086—Replace Cover on Power Terminals Hazardous voltage or energy may be present on power terminals. To reduce the risk of electric shock, make sure the power terminal cover is in place when the power terminal is not being serviced. Be sure uninsulated conductors are not accessible when the cover is in place.

Many router 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.

Note	Check the resistance value of the ESD-preventive strap periodically. The measurement should be 1–10 megohms.

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.

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

Note	Statement 7001—ESD Mitigation This equipment may be ESD sensitive. Always use an ESD ankle or wrist strap before handling equipment. Connect the equipment end of the ESD strap to an unfinished surface of the equipment chassis or to the ESD jack on the equipment if provided.

Warning

Statement 7003—Shielded Cable Requirements for Intrabuilding Lightning Surge 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.

Warning

Statement 7005—Intrabuilding Lightning Surge and AC Power Fault 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.

Warning

Statement 7011—Surge Protection Device Requirements for GR-1089 Antenna Ports Protect equipment antenna ports, that are classified as Type 6 according to GR-1089-CORE, with lightning surge protectors that are rated at a minimum of 600 V peak surge of 1.2/50 uS duration. Connecting a Cable to the GNSS Antenna Interface GNSS modules have built-in ESD protections on all pins, including the RF-input pin. However, additional surge protection is required if an outdoor antenna is being connected. The Lightning Protector must be able to provide a low clamping voltage (less than 600V). A lightning protection must be mounted at the place where the antenna cable enters the building. The primary lightning protection must be capable of conducting all potentially dangerous electrical energy to PE (Protective Earth). Surge arrestors should support DC-pass and suitable for the GPS frequency range as per the constellation used with low attenuation.

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 8000 Series Routers Data Sheet.

• Chassis is mounted at the bottom of the rack if it is the only unit in the rack.

• 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.

Note	Cisco 8000 Series Routers function in operating temperatures of up to 40°C at sea level. For every 300 meters (1000 ft) above sea level, the maximum temperature is reduced by 1°C. For more details on environmental requirements, see Cisco 8000 Series Routers Data Sheet.

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 2 AWG lug (1) is provided with the accessory kit. If you choose to use a different sized ground wire, you must procure your own two-hole lug that has .25 inch holes and .625 inch spacing between the holes.

• Grounding cable that is compatible with the ground lug being used to ground the equipment. The grounding cable must be long enough to reach the intended ground bus. It is recommended to consult with a licensed electrician on grounding methods that meet your local and national requirements.
