Observe the following general precautions when using and working with your router:

• 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 PEM cables carefully. Route system cables and the PEM 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.

The Cisco 8400 Series Routers are designed to meet the regulatory compliance and safety approval requirements. For detailed safety information, see Regulatory Compliance and Safety Information—Cisco 8400 Series Routers.

Warning

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

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	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

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

The intrabuilding port(s) of the equipment or subassembly, the management Ethernet port, is suitable for connection to intrabuilding or unexposed wiring or cabling only. The intrabuilding port(s) of the equipment or subassembly MUST NOT be metallically connected to interfaces that connect to the OSP or its wiring for more than 6 meters (approximately 20 feet). These interfaces are designed for use as intrabuilding interfaces only (Type 2, 4, or 4a ports as described in GR-1089) 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 an OSP wiring system.

Note	This equipment is suitable for installation in network telecommunications facilities.

Note	This equipment is suitable for installation in locations where the NEC applies.

Check the power at your site to ensure that you are receiving clean power (free of spikes and noise). Install a power conditioner if necessary.

Before you begin the installation of the router, review the safety guidelines in this chapter to avoid injuring yourself or damaging the equipment.

In addition, before replacing, configuring, or maintaining the router, review the safety warnings listed in Regulatory Compliance and Safety Information for the Cisco 8400 Series Routers.

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 router.

• The floor space that the router occupies can support the weight of the system.

• Electrical service to the site complies with the requirements.

• The electrical circuit servicing the router complies with the requirements.

• Consideration has been given to the console port wiring and limitations of the cabling involved, according to TIA/EIA-232F.

• The router Ethernet cabling distances are within limitations.

• The equipment rack in which you plan to install the router complies with requirements.

• In selecting the location of the rack, careful consideration has been given to safety, ease of maintenance, and proper airflow.

Environmental monitoring in the router protects the system and components from damage caused by excessive voltage and temperature conditions. To ensure normal operation and avoid unnecessary maintenance, plan and prepare your site configuration before installation. After installation, make sure that the site maintains the environmental characteristics described in the Cisco 8404-SYS-D Series Routers Datasheet.

For outside plant installation (cell site cabinet, hut, and so on), equipment must be protected against airborne contaminants, dust, moisture, insects, pests, corrosive gases, polluted air, or other reactive elements. Sealed equipment chamber with air-conditioning or a heat exchanger is recommended for OSP deployments. The equipment chamber must comply with the temperature and clearance requirements. Examples of such cabinets include IP 65/66 cabinets with heat exchanger complying with Telcordia GR487. Temperature must be maintained within –20ºC to +65ºC. The equipment shall be placed inside an enclosure (that is protected from direct outside weather and environmental stresses by the enclosure), and where the operating climate, as defined by Class 2 of GR-3108-CORE, is between: –40 to 149°F (–20 to +65°C) 5% and 85% RH.

For more information on Environmental properties and Regulatory standards, see the Cisco 8404-SYS-D datasheet

Temperature extremes may cause a system to operate at reduced efficiency and cause various problems, including premature aging and failure of chips, and failure of mechanical devices. Extreme temperature fluctuations may also cause chips to become loose in their sockets.

Observe the following guidelines:

• Ensure that the chassis has adequate ventilation.

• Don’t place the chassis within a closed-in wall unit or on top of cloth, which can act as thermal insulation.

• Don’t place the chassis where it receives direct sunlight, particularly in the afternoon.

• Don’t place the chassis next to a heat source of any kind, including heating vents.

• Adequate ventilation is important at high altitudes. Make sure that all the slots and openings on the system remain unobstructed, especially the fan vent on the chassis.

• Clean the installation site at regular intervals to avoid the buildup of dust and debris, which may cause a system to overheat.

Failure to observe these guidelines may damage the chassis' internal components.

The following sections describe how to plan for the installation of the router.

Cool air is circulated through the router by fan tray located along the left side of the router. Air flow is right to left, as shown in the figure below.

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.

The following guidelines will help you plan your equipment rack configuration:

• To ensure adequate air flow through the equipment rack, we recommend that you maintain a clearance of at least 80 mm (3.15 inches) on each side of the router at all times.

• If airflow through the equipment rack and the routers that occupy it is blocked or restricted, or if the ambient air being drawn into the rack is too warm, an overtemperature condition can occur within the rack and the routers that occupy it.

• The site should also be as dust-free as possible. Dust tends to clog the router fans, reducing the flow of cooling air through the equipment rack and the routers that occupy it, thus increasing the risk of an overtemperature condition.

• Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because each router generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. Heat that is generated by the equipment near the bottom of the rack can be drawn upward into the intake ports of the equipment above.

• When mounting a chassis in an open rack, ensure that the rack frame does not block the side intakes and the exhaust fans.

• When rack-installed equipment fails, especially equipment in an enclosed rack, try operating the equipment by itself, if possible. Power off all other equipment in the rack (and in adjacent racks) to give the router maximum cooling air and clean power.

• Avoid setting up the router in a location in which the router air intake vents may draw in the exhaust air from adjacent equipment. Consider how the air flows through the router; the airflow direction is side to side, with ambient air drawn in from the vents located on the front right of the router.

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

• The redundant power option provides a second, identical power supply to ensure uninterrupted power supply.

• Connect each power supply to a separate input power source. Otherwise, it results in a total power failure to the system due to a fault in the external wiring or a tripped circuit breaker.

• To prevent loss of input power, ensure that the maximum load on each circuit is within the current ratings of the wiring and the breakers.

• Circuit breaker specifications—a maximum of 60A for DC power feed is supported.

• Check the power at your site before installation, and periodically after installation, to ensure that you are receiving clean power. If necessary, install a power conditioner.

• Provide proper grounding to avoid personal injury and damage to the equipment due to power surges or lightning striking power lines. The chassis ground must be attached to a central office or other interior ground system.

Note

The chassis installation must comply with all the applicable codes, and is approved for use with only copper conductors. The ground bond-fastening hardware must be compatible 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.

Caution

The DC PSU requires external surge protection devices for installations where electrical surges higher than 2KV common mode and 1KV differential mode are expected. Failure to do so can result in permanent damage to the product.

This section contains guidelines for wiring and cabling at your site. When preparing your site for network connections to the Cisco 8404-SYS-D Router, 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:

• 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.

Before you install the Cisco 8404-SYS-D Router, 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 8404-SYS-D Router.

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 following sections provide guidelines for rack-mounting the Cisco8404-SYS-D Router:

We recommend that you follow these rack specifications.

Use the Installation Checklist that is shown in the following table to provide a record of what was done by whom and when. Use this list 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 the Site Log and Manufactures 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

Ensure that the floor under the rack supporting the Cisco 8404-SYS-D routers are capable of supporting the combined weight of the rack and all the other installed equipment.

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