This section contains site planning information, and will help you plan for the installation of the Cisco RF Gateway 10 UEQAM. It contains the following sections:
Observe the following general precautions when using and working with your Cisco RFGW-10 UEQAM system.
The Cisco RFGW-10 UEQAM require 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 RFGW-10 UEQAM are designed to meet the industry EMC, safety, and environmental standards described in the Regulatory Safety and Compliance Information for the Cisco RF Gateway 10 document.
Environmental monitoring in the Cisco RFGW-10 UEQAM 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 the site maintains the environmental characteristics as shown in Table 2-2 .
Be familiar with the physical characteristics of the Cisco RFGW-10 UEQAM to assist you in placing the system in the proper location.
Table 2-3 shows the weight and dimensions of the Cisco RFGW-10 UEQAM.
Table 2-3 Physical Characteristics of Cisco RFGW-10 UEQAM
The following list describes additional Cisco RFGW-10 chassis characteristics:
Ensure that the floor under the rack supporting the Cisco RFGW-10 UEQAM is capable of supporting the combined weight of the rack and all other installed equipment.
To assess the weight of the fully configured Cisco RFGW-10 UEQAM respectively, refer to Table 2-3 .
For additional information about floor loading requirements, consult the document GR-63-CORE, Network Equipment Building System (NEBS) Requirements: Physical Protection .
The Cisco RFGW-10 UEQAM 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 the Cisco RFGW-10 UEQAM:
Note The Cisco RFGW-10 UEQAM installation must comply with all 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 an AWG #6 gauge wire, copper ground conductor at a minimum.
Each Cisco RFGW-10 UEQAM requires a dedicated electrical circuit. If you equip it with dual power feeds, provide a separate circuit for each DC PEM to avoid compromising the power redundancy feature.
The Cisco RFGW-10 UEQAM can be powered by a DC source. Ensure that the equipment grounding is present and observe power strip ratings. Make sure that the total ampere rating of all products plugged into the power strip does not exceed 80% of the rating.
Table 2-4 contains specifications for DC powered systems for all Cisco RFGW-10 UEQAM.
Table 2-5 lists the DC PEM rating requirements for Cisco RFGW-10 UEQAM.
This section contains guidelines for wiring and cabling at your site. When preparing your site for network connections to the Cisco RFGW-10 UEQAM, 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, 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 install the Cisco RFGW-10 UEQAM, have all additional external equipment and cables on hand. For ordering information, contact a customer service representative.
The extent of your network and the distances between network interface connections depend in part on the following factors:
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 RFGW-10 UEQAM.
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.
The Supervisor provides a console port to connect a terminal or computer for local console access. The Supervisor also provides an auxiliary port to connect to a modem for remote dial-in console access.
Both ports have RJ-45 connectors, support RS-232 asynchronous data, and have distance recommendations specified in the IEEE RS-232 standard.
When wires are run for any 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 Cisco RFGW-10 UEQAM system.
All 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 Cisco RFGW-10 UEQAM 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.
Table 2-6 lists electrode magnetic compliance standards for the Cisco RFGW-10 UEQAM.
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.
If signal wires exceed recommended cabling distances, or if signal wires pass between buildings, you should consider the effect that a lightning strike in your vicinity might have on the Cisco RFGW-10 UEQAM.
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 Cisco RFGW-10 UEQAM operating environment.
The Cisco RFGW-10 UEQAM is designed for standalone, two-post 19-inch rack-mount, four-post 19-inch rack-mount and closed cabinet systems with front and rear doors.
The sections that follow describe criteria for selecting a rack to mount the Cisco RFGW-10 UEQAM, guidelines for placing the rack for reliable operation, and safety precautions to take to prevent bodily injury when mounting a Cisco RFGW-10 UEQAM system in a rack.
The following rack-mount guidelines are provided to ensure your safety:
The Cisco RFGW-10 UEQAM can be mounted in most two-post or four-post, 19-inch equipment racks that comply with the Electronics Industries Association (EIA) standard for equipment racks (EIA-310-D 19-inch). The rack must have at least two posts with mounting flanges to mount the chassis.
The distance between the center lines of the mounting holes on the two mounting posts must be 18.31 inches ± 0.06 inch (46.50 cm ± 0.15 cm). The rack-mounting hardware included with the chassis is suitable for most 19-inch equipment racks.
We recommend that you mount the Cisco RFGW-10 UEQAM in an equipment rack that includes the necessary rack-mounting hardware, which is suitable for most 19-inch equipment racks.
Consider installing the Cisco RFGW-10 UEQAM in a rack with the following features:
The placement of the rack can affect personnel safety, system maintenance, and the system ability to operate within the environmental characteristics described in Table 2-2 . Choose a proper location for the Cisco RFGW-10 UEQAM by following the guidelines below.
If the Cisco RFGW-10 UEQAM 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 center of gravity is as low as possible.
For additional information about the proper placement of electronic equipment, consult the document GR-63-CORE, Network Equipment Building System (NEBS) Requirements: Physical Protection.
Keep at least 3 feet of clear space in front and behind the rack. This space ensures that you can remove the Cisco RFGW-10 UEQAM components and perform routine maintenance and upgrades easily.
Avoid installing the Cisco RFGW-10 UEQAM in a congested rack and consider how the routing of cables from other pieces of equipment in the same rack could affect access to the routers cards.
The front and back of the chassis must remain unobstructed to ensure adequate airflow and prevent overheating inside the chassis.
Allow the following clearances for normal system maintenance:
To avoid problems during installation and ongoing operation, follow these general precautions when you plan the equipment locations and connections:
Ensure the location of the Cisco RFGW-10 UEQAM 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 Cisco RFGW-10 UEQAM 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 Cisco RFGW-10 UEQAM. The Cisco RFGW-10 UEQAM airflow direction is front to back with ambient air drawn in from the venting located on the chassis front sides.
Table 2-7 is provided to help you perform and account for all the site planning tasks.
Table 2-7 Site Planning Checklist
Electrostatic discharge (ESD) damage, occurs when electronic cards or components are improperly handled and can result in complete or intermittent failures. The Supervisors, and all line cards consist of a printed circuit card that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the cards from ESD, use an antistatic strap each time you handle the modules. Handle the carriers by the edges only; never touch the cards or connector pins.
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 an microprocessor. As you continue to work on your system, periodically touch an unpainted metal surface on the computer chassis.
Following are guidelines for preventing ESD damage:
All 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:
In addition, use the guidelines that follow when working with any equipment that is disconnected from a power source but is still connected to telephone wiring or other network cabling.
Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001
