Site Power Guidelines

The Cisco Catalyst CW9800H1 and CW9800H2 Wireless Controllerss have 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 for the controller:

  • The redundant power option provides a second, identical power supply to ensure 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 of the two 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 the total maximum load on each circuit supplying the power supplies is within the current ratings of the wiring and 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.

Electrical Circuit Requirements

The Cisco Catalyst CW9800H1 and CW9800H2 Wireless Controllerss require a dedicated electrical circuit. If you equip it with dual-power feeds, you must provide a separate circuit for each power supply to avoid compromising the power redundancy feature.

The Cisco Catalyst CW9800H1 and CW9800H2 Wireless Controllerss can be powered by an AC or DC source. Ensure that equipment grounding is present and observe power-strip ratings. Make sure that the total ampere rating of all the products plugged into the power strip does not exceed 80 percent of the rating.

Site Cabling Guidelines

This section contains guidelines for wiring and cabling at your site. When preparing your site for network connections to the Cisco Catalyst CW9800H1 and CW9800H2 Wireless Controllerss, consider the type of cable required for each component, and the cable limitations. Consider the distance limitations for signaling, EMI, and connector compatibility. Possible cable types are fiber, thick or thin coaxial, foil twisted-pair cabling, or unshielded twisted-pair cabling.

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

Before you install the controller, have all the additional external equipment and cables at hand. For ordering information, contact a Cisco customer service representative.

The extent of your network and the distances between 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 guidelines when planning your network connections prior to installing the Cisco Catalyst CW9800H1 and CW9800H2 Wireless Controllerss.

If wires exceed 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.


Note

If you are using a copper cable to connect the Redundancy Ports (RPs) back-to-back, the maximum length of the cable can be 30 meters. If you want to use a longer cable, you will need to switchover to fiber optic cables.

Console Port Connections

The Cisco Catalyst CW9800H1 and CW9800H2 Wireless Controllers provides console ports to connect a terminal or computer for local console access.

The RJ-45 connector support RS-232 asynchronous data, and have distance recommendations specified in the IEEE RS-232 standard.

USB Serial Console

The USB serial console port connects directly to the USB connector of a PC using any USB form type to 5-pin USB Type-B cable. The USB Console supports full speed (12Mbps) operation. The console port does not support hardware flow control.


Note

  • Always use shielded USB cables with a properly terminated shield. The USB serial console interface cable must not exceed 3 meters in length.

  • Only one console port can be active at a time. When a cable is plugged into the USB console port, the RJ-45 port becomes inactive. Conversely, when the USB cable is removed from the USB port, the RJ-45 port becomes active.

  • 4-pin USB Type-B connectors are easily confused with 5-pin USB Type-B connectors. Only 5-pin USB Type-B is supported.

Interference Considerations

When wires are run for a significant distance, there is a risk that stray signals will be induced on the wires as interference. If interference signals are strong, they can cause data errors or damage to the equipment.

The following sections describe sources of interference and how to minimize its effects on the controller.

Electromagnetic Interference

All the equipment powered by AC current can propagate electrical energy that can cause electromagnetic interference (EMI) and possibly affect the operation of other equipment. The typical sources of EMI are equipment power cords and power service cables from electric utility companies.

Strong EMI can destroy the signal drivers and receivers in the controller and even create an electrical hazard by causing power surges through power lines into installed equipment. These problems are rare, but could be catastrophic.

To resolve these problems, you need specialized knowledge and equipment, which could consume substantial time and money. However, you should ensure that you have a properly grounded and shielded electrical environment, paying special attention to the need for electrical surge suppression.

The following table lists electrode magnetic compliance standards for the controller.

  • EN 62368-1

Radio Frequency Interference

When electromagnetic fields act over a long distance, radio frequency interference (RFI) can be propagated. Building wiring can often act as an antenna, receiving the RFI signals and creating more EMI on the wiring.

If you use twisted-pair cable in your plant wiring with a good distribution of grounding conductors, the plant wiring is unlikely to emit radio interference. If you exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal.

Lightning and AC Power Fault Interference

As this product is safety certified for indoor connection only, if signal wires exceed recommended cabling distances, you should consider the effect that a lightning strike in your vicinity might have on the controller.

The electromagnetic pulse (EMP) generated by lightning or other high-energy phenomena can couple enough energy into unshielded conductors to damage or destroy electronic equipment. If you have previously experienced such problems, you should consult with RFI/EMI experts to ensure that you have adequate electrical surge suppression and shielding of signal cables in your controller operating environment.

Rack-Mounting Guidelines

This section describes guidelines on rack-mounting.

Precautions for Rack-Mounting

The following rack-mounting guidelines are provided to ensure your safety:


Warning
To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable.

The following guidelines are provided to ensure your safety:

  • This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

  • When mounting this unit 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 unit in the rack.

Statement 1006

  • Do not move large racks by yourself. Due to the height and weight of a rack, a minimum of two people are required to accomplish this task.

  • Ensure that the rack is level and stable before extending a component from the rack.

  • Ensure that proper airflow is provided to the components in the rack.

  • Do not step or stand on any component or system when servicing other systems or components in a rack.

General Rack-Selection Guidelines

The Cisco Catalyst CW9800H1 Wireless Controller and Cisco Catalyst CW9800H2 Wireless Controller can be mounted in most two-post or four-post, 19-in. equipment racks that comply with the Electronics Industries Association (EIA) standard for equipment racks (EIA-310-D 19-in.). The rack must have at least two posts with mounting flanges to mount the chassis.


Warning
To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of 104°F (40°C).

Statement 1047

The distance between the center lines of the mounting holes on the two mounting posts must be 18.31 in. ± 0.06 in. (46.50 cm ± 0.15 cm). The rack-mounting hardware included with the chassis is suitable for most 19-in. (48.3-cm) equipment racks.

Consider installing the controller in a rack with the following features:

  • EIA or ETSI hole patterns in the mounting rails. Required mounting hardware is shipped with the controller. If the rack that you plan to install the system in has metric-threaded rails, you must provide your own metric-mounting hardware.

  • Perforated top and open bottom for ventilation to prevent overheating.

  • Leveling feet for stability.


Note
The controller must not be installed in an enclosed rack because the chassis requires an unobstructed flow of cooling air to maintain acceptable operating temperatures for its internal components. Installing the controller in any type of enclosed rack—even with the front and back doors removed—could disrupt the air flow, trap heat next to the chassis, and cause an over temperature condition inside the controller. If you use an enclosed rack, make certain that there are air vents on all sides of the rack and there is proper ventilation.

Guidelines for 23-in. (Telco) Racks

If needed, you can also install the Cisco Catalyst CW9800H1 and CW9800H2 Wireless Controllerss in 23-in. (Telco) racks. For information on the adapters needed for 23 in. racks, contact the Newton Instrument Company:

Equipment Rack Guidelines

The placement of racks can affect personnel safety, system maintenance, and the system’s ability to operate within the environmental characteristics described in Table: Cisco Catalyst CW9800H1 Wireless Controller and Cisco Catalyst CW9800H2 Wireless Controller Environmental Tolerance. Choose a proper location for the controller by following the guidelines below.

Locating for Safety

If the Cisco Catalyst CW9800H1 Wireless Controller or the Cisco Catalyst CW9800H2 Wireless Controller is the heaviest or the only piece of equipment in the rack, consider installing it at or near the bottom to ensure that the rack’s center of gravity is as low as possible.

Locating for Easy Maintenance

Keep at least 3 feet of clear space in front of and behind the rack. This space ensures that you can remove the controller components and perform routine maintenance and upgrades easily.

Avoid installing the controller in a congested rack and consider how the routing of cables from other pieces of equipment in the same rack might affect access to the controller’s cards.

The front and top of the chassis must remain unobstructed to ensure adequate airflow and prevent overheating inside the chassis.

Allow the following clearances for normal system maintenance:

  • At the top of the chassis—At least 3 in. (7.6 cm)

  • In front of the chassis—3 to 4 ft (91.44 cm to 121.92 cm)

To avoid problems during installation and ongoing operation, follow these general precautions when you plan the equipment locations and connections:

  • Use the show environment all and the show facility-alarm status commands regularly to check the internal system status. The environmental monitor continually checks the interior chassis environment; it provides warnings for high temperature and creates reports on any occurrences. If warning messages are displayed, take immediate action to identify the cause and correct the problem. For more information on these commands, see the Environmental Monitoring and Reporting Functions section.

  • Keep the controller off the floor and out of the areas that collect dust.

  • Follow ESD-prevention procedures to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure.

Locating for Proper Airflow

Ensure that the location of the controller has enough airflow to keep the system operating within the environmental characteristics, and the air temperature is sufficient to compensate for the heat dissipated by the system.

Avoid locating the controller in a location in which the chassis air intake vents could draw in the exhaust air from adjacent equipment. Consider how the air flows through the controller. The airflow direction is front to back with ambient air drawn in from the venting located on the chassis’ front sides.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage occurs when electronic cards or components are improperly handled resulting in complete or intermittent failures. Static electricity can harm delicate components inside your system. To prevent static damage, discharge static electricity from your body before you touch any of your system components, such as a microprocessor. As you continue to work on your system, periodically touch an unpainted metal surface on the computer chassis.

The following are guidelines for preventing ESD damage:

  • Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact. Before removing a card from the chassis, connect the equipment end of the strap to the ESD plug at the bottom of the chassis below the power entry modules.

  • Handle line cards by faceplates and carrier edges only; avoid touching the card components or connector pins.

  • When removing a module, place the removed module component-side-up on an antistatic surface or in a static-shielding bag. If the module is to be returned to the factory, immediately place it in a static-shielding bag.

  • Avoid contact between the modules and clothing. The wrist strap protects the card from ESD voltages only on the body; ESD voltages on clothing can still cause damage.

  • When transporting a sensitive component, place it in an antistatic container or packaging.

  • Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads.


Caution
For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 ohms.

Caution
Always tighten the captive installation screws on all the system components when you are installing them. These screws prevent accidental removal of the module, provide proper grounding for the system, and help ensure that the bus connectors are properly seated in the backplane.

Electrical Safety

All the system components are hot-swappable. They are designed to be removed and replaced while the system is operating, without presenting an electrical hazard or damage to the system.

Follow these basic guidelines when you are working with any electrical equipment:

  • Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working.

  • Disconnect all power and external cables before installing or removing a chassis.

  • Never assume that power has been disconnected from a circuit; always check.

  • Do not perform any action that creates a potential hazard to people or makes the equipment unsafe. Never install equipment that appears damaged.

  • Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

Chassis-Lifting Guidelines

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.


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.

Statement 1032

Each time you lift the chassis or any heavy object, 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.

Tools and Equipment

The following tools and equipment are recommended as the minimum necessary equipment to install the Cisco Catalyst CW9800H1 and CW9800H2 Wireless Controllers. You may need additional tools and equipment to install associated equipment and cables. You may also require test equipment to check electronic and optical signal levels, power levels, and communications links.

  • Philips hand screwdriver

  • 3.5-mm flat-blade screwdriver

  • Tape measure (optional)
