CH A P T E R 2 Preparing for Installation This chapter describes the site requirements for installing the Cisco uBR 3x10 RF Switch. The chapter contains the following sections: • Safety, page 2-2 • Site Requirements, page 2-5 • Provisioning the Headend, page 2-7 • Tools for Installation, page 2-9 • Verifying the Shipping Container Contents, page 2-11 Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Chapter 2 Preparing for Installation Safety Safety The following guidelines will help to ensure your safety and protect the equipment. This list does not cover all potentially hazardous situations, so be alert. • The installation of your Cisco uBR 3x10 RF Switch should be in compliance with national and local electrical codes. In the United States, National Fire Protection Association (NFPA) 70, United States National Electrical Code. In Canada, Canadian Electrical Code, part I, CC22.1.
Chapter 2 Preparing for Installation Safety Lifting the Chassis 82135 Figure 2-1 Safety with Electricity The Ethernet controller and upstream and downstream switch modules are designed to be removed and replaced while the system is operating without presenting an electrical hazard or damage to the system. Caution You must power down the system before removing or replacing the power supply assembly.
Chapter 2 Preparing for Installation Safety Warning • Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations. • Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface. • Use caution when installing or modifying telephone lines. Do not work on the system or connect or disconnect cables during periods of lightning activity.
Chapter 2 Preparing for Installation Site Requirements Site Requirements To ensure normal operation and avoid unnecessary maintenance, plan your site configuration and prepare your site before installation. Take into account the following criteria: Note To locate the most reliable channels for your downstream and upstream channel plans, we recommend that you perform a sweep of all available channels for at least a 24 hours to verify the presence or absence of impulse and ingress noise.
Chapter 2 Preparing for Installation Site Requirements Site Environment Table 2-1 lists the operating and nonoperating site temperature requirements. The following ranges are those within which the Cisco uBR 3x10 RF Switch continues to operate; however, a measurement that is approaching the minimum or maximum of a range indicates a potential problem. You can maintain normal operation by anticipating and correcting environmental anomalies before they approach a maximum operating range.
Chapter 2 Preparing for Installation Provisioning the Headend Provisioning the Headend The following sections describe the provisioning required at the cable headend before you install the Cisco uBR 3x10 RF Switch. Headend Certification The cable headend plant must pass both analog and digital certification: • In the United States, the Federal Communications Commission (FCC) mandates certification. • For international certification, consult with local agencies for certification requirements.
Chapter 2 Preparing for Installation Provisioning the Headend signaling; however, you can usually get good results at speeds and distances far greater than these. For example, the recommended maximum rate for V.35 is 2 Mbps, and it is commonly used at 4 Mbps without any problems. If you understand the electrical problems that might arise and can compensate for them, you should get good results with rates and distances greater than those shown here; however, do so at your own risk.
Chapter 2 Preparing for Installation Tools for Installation Caution To prevent the chassis from overheating, never install the Cisco uBR 3x10 RF Switch in an enclosed rack or room that is not properly ventilated or air conditioned. The Cisco uBR 3x10 RF Switch overheats if the input air temperature reaches 105°F (41°C). Figure 2-2 Dimensions 15.12 in. (384.05 mm) 82134 5.22 in. (132.59 mm) 17.0 in. (431.
