About This Guide

This preface discusses the audience, organization, conventions, and terms and acronyms used in this guide. It also discusses related documentation and how to access electronic documentation.

Audience

This guide is intended for service technicians who have no experience installing routers. The goal of these technicians is to connect the router to the network as quickly as possible.

This guide provides conceptual information on topics, such as serial cables, that you need to understand to successfully install your router. Conceptual information is usually in a separate section or appendix, such as "Selecting a Serial Cable," so that technicians who are not interested or already understand the topic can skip this information.

Organization

This guide contains the following information:

• Product Overview---Describes the Cisco 805 router and its features.

• Installing the Cisco 805 Router---Provides information on safety, required equipment, unpacking the box, connecting and mounting the router, and verifying the router connections.

• Troubleshooting---Describes problems with the router and how to identify and solve them.

• Selecting a Serial Cable---Explains how to select a serial cable to connect your serial device to the router serial port. It also provides Cisco part numbers for cables that you can order.

• Technical Specifications---Provides physical dimensions, environmental operating ranges, and power specifications for the router.

• Connector and Cable Specifications---Contains port connector pinouts and specifications for cables that you might need to provide.

• A wall-mount template is provided at the back of this manual. For more information, see the "Mounting the Router on a Wall" section in "Installing the Cisco 805 Router."

La traduzione delle avvertenze riportate in questa pubblicazione si trova nel documento Regulatory Compliance and Safety Information (Conformità alle norme e informazioni sulla sicurezza) che accompagna questo dispositivo.

Advarsel  Dette varselsymbolet betyr fare. Du befinner deg i en situasjon som kan føre til personskade. Før du utfører arbeid på utstyr, må du vare oppmerksom på de faremomentene som elektriske kretser innebærer, samt gjøre deg kjent med vanlig praksis når det gjelder å unngå ulykker. Hvis du vil se oversettelser av de advarslene som finnes i denne publikasjonen, kan du se i dokumentet Regulatory Compliance and Safety Information (Overholdelse av forskrifter og sikkerhetsinformasjon) som ble levert med denne enheten.

Aviso  Este símbolo de aviso indica perigo. Encontra-se numa situação que lhe poderá causar danos físicos. Antes de começar a trabalhar com qualquer equipamento, familiarize-se com os perigos relacionados com circuitos eléctricos, e com quaisquer práticas comuns que possam prevenir possíveis acidentes. Para ver as traduções dos avisos que constam desta publicação, consulte o documento Regulatory Compliance and Safety Information (Informação de Segurança e Disposições Reguladoras) que acompanha este dispositivo.

¡Advertencia!  Este símbolo de aviso significa peligro. Existe riesgo para su integridad física. Antes de manipular cualquier equipo, considerar los riesgos que entraña la corriente eléctrica y familiarizarse con los procedimientos estándar de prevención de accidentes. Para ver una traducción de las advertencias que aparecen en esta publicación, consultar el documento titulado Regulatory Compliance and Safety Information (Información sobre seguridad y conformidad con las disposiciones reglamentarias) que se acompaña con este dispositivo.

Varning!  Denna varningssymbol signalerar fara. Du befinner dig i en situation som kan leda till personskada.

Terms and Acronyms

This section describes terms and acronyms that are used in this guide.

The 10-Mbps baseband Ethernet specification that uses two pairs of twisted-pair cabling (Category 3, 4, or 5): one pair for transmitting data and the other for receiving data.

Connect this device to router serial port for dial-up connection.

Signal that indicates whether the serial interface is active.

A cable that wires a pin to its opposite pin; for example, Receive+ is wired to Transmit+. This cable connects two similar devices, such as a data terminal equipment (DTE) and data communications equipment (DCE) device.

Channel service unit/data service unit. Connect this type of device to router serial port for synchronous leased-line, Frame Relay, or X.25 connection.

Data communications equipment. This type of equipment provides a physical connection to the network and forwards traffic. A synchronous DCE also provides a clocking signal used to synchronize data transmission between DCE and DTE devices, while an asynchronous DCE does not provide a clocking signal. For more information, see the "DTE or DCE" section in "Selecting a Serial Cable."

Data terminal equipment. This type of equipment connects to a data network through a DCE device, such as a modem, and typically uses clocking signals generated by the DCE. For more information, see the "DTE or DCE" section in "Selecting a Serial Cable."

Dynamic RAM. Dynamic RAM that stores information that must be refreshed periodically in capacitors.

The nonvolatile storage that can be electrically erased and reprogrammed so that data can be stored, booted, and rewritten as necessary.

With this button, you can connect hubs, servers, PCs, and workstations using the yellow Ethernet (straight-through) cable instead of using a crossover Ethernet cable, which you would need to supply. This button identifies the device that you connect to the router Ethernet port using the yellow Ethernet cable. Setting the button to HUB (in) indicates that you are connecting a hub; setting the button to NO HUB (out) indicates that you are connecting a server, PC, or workstation. For information on how the setting of an equivalent hub button can affect the setting of this router button, refer to the "Connecting an Ethernet Device" section in "Installing the Cisco 805 Router."

Indicates that a connection between the router and an Ethernet device exists.

Media-dependent interface. A port on a Ethernet network device used to connect the device to the Ethernet network, usually through a hub or switch.

Media-dependent interface, crossover. A port on an Ethernet hub, such as the Cisco 1528 Micro Hub 10/100, that connects the Ethernet network devices through the MDI port to create a network.

Network interface card. A board that provides network communication capabilities to and from a computer system. Also called an adapter.

Safety extra-low voltage. A secondary circuit that under normal conditions has a voltage less than 42.4V peak or 42 Vdc. Under a single fault condition, this circuit should not exceed these values for longer than 0.2 seconds and should not exceed 71V peak or 120 Vdc.

A cable that wires a pin to its equivalent pin. This cable typically connects a router to a hub. A straight-through Ethernet cable is the most common cable used.

Telecommunications network voltage. A secondary circuit that under normal operating conditions, carriers telecommunication signals. Telecommunications signals are a steady state, varying amplitude, or intermittent voltage or current intended for use on a telecommunications network. A telecommunications network is considered a metallically terminated circuit intended to carry telecommunication signals for voice, data, or other communication. These networks might be publicly or privately owned. They might be subjected to overvoltages due to atmospheric discharges or power line failures.
