Do not dismantle, crush, puncture, use a sharp tool to remove, short the external contacts, or dispose of the battery in fire. Do not use if battery is warped or swollen. Do not store or use battery in a temperature > . Do not store or use battery in low air pressure environment < .

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.

• 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 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.

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.

Warning

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

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 8608 Router 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) elevation upto 1800 meters (6000 ft), the maximum temperature is reduced by 1°C. For more details on environmental requirements, see Cisco 8608 Router 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 ground lug (1).

• A crimping tool specified by the lug manufacturer that is large enough to accommodate the girth of the lug.

• Wire-stripping tool.

This section illustrates how the building that houses the chassis must be properly grounded to the earth ground.

Note	Unless specified otherwise, the image is only for representational purposes. The rack's actual appearance and size may vary.

Note	This image is only for representational purposes. Your grounding requirement depends on your building.

This section illustrates how to prepare yourself before removing the chassis from the sealed antistatic bag. The figures show how to cuff the ESD strap around the wrist and the ground cord that connects the cuff to the ground. ESD wrist straps are the primary means of controlling static charge on personnel.

To ensure adequate airflow, we recommended that you maintain a minimum of 6 in. (15.24 cm) front and rear clearance for air intake/exhaust.

If the router is installed in a perforated door cabinet, maintain a minimum of 6 in. (15.24 cm) from the inside of the door. The front and rear doors of the cabinet must be perforated with a minimum open area of 70%.

Following figure shows the clearances required for installation of Cisco 8600 Series Routers.
