Warning

This equipment needs to be grounded. Use a green and yellow 6 AWG ground wire to connect the host to earth ground during normal use. Statement 383

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD can occur when electronic printed circuit cards are improperly handled and can cause complete or intermittent failures. When removing and replacing modules, always follow ESD prevention procedures:

• Ensure that the router chassis is physically connected to earth ground.
• Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. To channel unwanted ESD voltages safely to ground, connect the clip to an unpainted surface of the chassis frame. To guard against ESD damage and shocks, the wrist strap and cord must operate effectively.
• If no wrist strap is available, ground yourself by touching a metal part of the chassis.
• When installing a component, use any available ejector levers or captive installation screws to properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.
• When removing a component, use available ejector levers or captive installation screws, if any, to release the bus connectors from the backplane or midplane.
• Handle components by their handles or edges only; do not touch the printed circuit boards or connectors.
• Place a removed component board side up on an antistatic surface or in a static-shielding container. If you plan to return the component to the factory, immediately place it in a static-shielding container.
• 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.
• Never attempt to remove the printed circuit board from the metal carrier.

Note	For the safety of your equipment, periodically check the resistance value of the antistatic wrist strap. It should be between 1 and 10 Mohm.

Observe the following general precautions when using and working with your Cisco NCS 4216 14RU system:

• Keep your system components away from radiators and heat sources and do not block cooling vents.
• Do not spill food or liquids on your system components and never operate the product in a wet environment.
• Do not push any objects into the openings of your system components. Doing so can cause fire or electric shock by shorting out interior components.
• Position system cables and power supply cables carefully. Route system cables and the power supply cable and plug so that they cannot be stepped on or tripped over. Be sure that nothing else rests on your system component cables or power cable.
• Do not modify power cables or plugs. Consult a licensed electrician or your power company for site modifications. Always follow your local and national wiring rules.
• If you turn off your system, wait at least 30 seconds before turning it on again to avoid system component damage.

Use the following checklist to perform and account for all the site planning tasks described in this chapter:

• The site meets the environmental requirements.
• The site’s air conditioning system can compensate for the heat dissipation of the Cisco NCS 4216 14RU.
• The floor space that the Cisco NCS 4216 14RU occupies can support the weight of the system.

• The equipment rack in which you plan to install the Cisco NCS 4216 14RU complies with requirements.
• In selecting the location of the rack, careful consideration has been given to safety, ease of maintenance, and proper airflow.

The Cisco NCS 4216 14RU requires specific environmental operating conditions. Temperature, humidity, altitude, and vibration can affect the performance and reliability of the router. The following sections provide specific information to help you plan for the proper operating environment.

The Cisco NCS 4216 14RU is designed to meet the industry EMC, safety, and environmental standards described in the Regulatory Compliance and Safety Information for the Cisco NCS 4200 Series Aggregation Routers.

Cool air is circulated through the Cisco NCS 4216 14RU by fan trays located on top and bottom of the chassis and the air flow is from front to back, as shown in the figure below.

To ensure adequate airflow, it is recommended that you maintain a minimum clearance distance always, as mentioned in the following figure.

The fan trays maintain acceptable operating temperatures for the internal components by drawing in cool air through the vents, and circulating the air through the chassis.

Ensure that the floor under the rack supporting the Cisco NCS 4216 14RU is capable of supporting the combined weight of the rack and all the other installed equipment.

To assess the weight of a fully configured Cisco NCS 4216 14RU, refer to the System Specifications section.

For additional information about floor loading requirements, consult GR-63-CORE, Network Equipment Building System (NEBS) Requirements: Physical Protection.

The Cisco NCS 4216 14RU has specific power and electrical wiring requirements. Adhering to these requirements ensures reliable operation of the system. Follow these precautions and recommendations when planning your site power for the Cisco NCS 4216 14RU:

• The redundant power option ensures that power to the chassis continues uninterrupted if one power supply fails or input power on one line fails.
• In systems configured with the redundant power option, connect each feed of the power supplies to a separate input power source. If you fail to do this, your system might be susceptible to total power failure due to a fault in the external wiring or a tripped circuit breaker.
• To prevent a loss of input power, be sure that the total maximum load on each circuit supplying the power supplies is within the current ratings of the wiring and the breakers.
• Check the power at your site before installation and periodically after installation to ensure that you are receiving clean power. Install a power conditioner if necessary.
• Provide proper grounding to avoid personal injury and damage to the equipment due to lightning striking power lines or due to power surges. The chassis ground must be attached to a central office or other interior ground system.

Caution

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.

Note

The Cisco NCS 4216 14RU installation must comply with all the applicable codes and is approved for use with copper conductors only. The ground bond fastening hardware should be of compatible material and preclude loosening, deterioration, and electrochemical corrosion of hardware and joined material. Attachment of the chassis ground to a central office or other interior ground system must be made with a 6 AWG gauge wire, copper ground conductor at a minimum.

The maximum power draw of the Cisco NCS 4216 14RU chassis and its configurable hardware components are listed in the following table. The maximum power draw values are not affected by the number of PSUs installed in the chassis.

This section contains guidelines for wiring and cabling at your site. When preparing your site for network connections to the Cisco NCS 4216 14RU, consider the type of cable required for each component, and the cable limitations. Consider the distance limitations for signaling, electromagnetic interference (EMI), and connector compatibility. Possible cable types are fiber, thick or thin coaxial, foil twisted-pair, or unshielded twisted-pair cabling.

Also consider any additional interface equipment you need, such as transceivers, hubs, switches, modems, channel service units (CSU), or data service units (DSU).

Before you begin, read these important notes about cabling:

• The T1/E1 interface module for the Cisco NCS 4216 14RU uses a high-density connector that requires the use of a T1/E1 interface cable and a customer-provided patch panel. For more information, see the Connecting T1/E1 cables section.
• Shielded cables must be used to connect to the RJ-45 alarm connector on the fan tray in order to comply with FCC/EN55022/CISPR22 Class A emissions requirements. For information about the fan tray alarm port, see the Connecting the Fan Tray Alarm Port section.

Before you install the Cisco NCS 4216 14RU, have all the additional external equipment and cables on hand. For information about ordering, contact a Cisco customer service representative.

The extent of your network and the distances between the network interface connections depend in part on the following factors:

• Signal type
• Signal speed
• Transmission medium

The distance and rate limits referenced in the following sections are the IEEE-recommended maximum speeds and distances for signaling purposes. Use this information as a guideline in planning your network connections prior to installing the Cisco NCS 4216 14RU.

If wires exceed the recommended distances, or if wires pass between buildings, give special consideration to the effect of a lightning strike in your vicinity. The electromagnetic pulse caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic devices. If you have had problems of this sort in the past, you may want to consult experts in electrical surge suppression and shielding.

The sections provide guidelines for rack-mounting the Cisco NCS 4216 14RU.

Note	You can install the NCS4216-F2B-SA chassis only into a 23-inches EIA Rack.

To assist you with your installation and to provide a record of what was done by whom and when, photocopy the Cisco NCS 4216 14RU Installation Checklist shown in the table below. Use this to record the completion and verification of each procedure. After the checklist is completed, place it in your Site Log along with the other records pertaining to your new Cisco router.

The Site Log provides a record of all the actions related to installing and maintaining the router. Keep it in an accessible place near the chassis so that anyone who performs tasks has access to it.

Create the Site Log prior to the installation. (See Appendix A, Site Log and Manufacturers section for more information on the Site Log as well as a sample Site Log that can be used to make copies.)

The chassis is not intended to be moved frequently. Before you install the system, ensure that your site is properly prepared so that you can avoid having to move the chassis later to accommodate power sources and network connections.

Each time you lift the chassis, follow these guidelines:

• Ensure that your footing is solid, and balance the weight of the chassis between your feet.
• Lift the chassis slowly; never move suddenly or twist your body as you lift.
• Keep your back straight and lift with your legs, not your back. If you must bend down to lift the chassis, bend at the knees, not at the waist, to reduce the strain on your back muscles.
• Do not remove installed components from the chassis.
• Always disconnect all external cables before lifting or moving the chassis.

Warning

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. Lift the unit only by using handles that are an integral part of the chassis, or by grasping the chassis underneath its lower edge. Statement 163
