THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

• Regulatory Compliance, page 1-17

General Descriptions of the Router Models

This section provides a general description of each of the router models.

• Cisco 851 and Cisco 871 Ethernet-to-Ethernet Routers

• Cisco 857 and Cisco 877 ADSL-over-POTS Routers

• Cisco 876 ADSL-over-ISDN Router

CHA P TER

• Cisco 878 SHDSL Router

Cisco 851 and Cisco 871 Ethernet-to-Ethernet Routers

The Cisco 851 and Cisco 871 Ethernet-to-Ethernet routers can connect a corporate teleworker or a small office to an Internet service provider (ISP) over a broadband or Ethernet connection to a corporate LAN or to the Internet. The Cisco 851 and Cisco 871 routers are switch-capable routers that provide a 4-port Ethernet switch for the LAN. These routers are capable of bridging and multiprotocol routing between LAN and WAN ports.

Universal Serial Bus (USB) ports on the Cisco 871 router provide connection for USB devices such as security tokens, flash memory sticks, and printers.

The front panels of the Cisco 851 and Cisco 871 routers are identical. (See Figure 1-1.) Figure 1-2 shows the back panel of the Cisco 851 router, and Figure 1-3 shows the back panel of the Cisco 871 router.

The Cisco 851 wireless model supports the use of a single 2.4-GHz antenna (see Figure 1-2), and the Cisco 871 wireless model supports the use of two 2.4-GHz antennas (see Figure 1-3).

Router Ports on the Cisco 851 and Cisco 871 Back Panel

The Cisco 851 and Cisco 871 routers have the following ports on the back panel:

• Four 10/100BASE-T RJ-45 Fast Ethernet LAN ports with a built-in switch

• One 10/100BASE-T RJ-45 WAN Fast Ethernet port

• One RJ-45 console port

• Two USB ports (on the Cisco 871 router only)

USB Port Power Allocation on the Cisco 871 Router

The power available for each of the two USB ports is 500 mA. Power is dynamically allocated to each port as needed, up to 500 mA.

Cisco 857 and Cisco 877 ADSL-over-POTS Routers

The Cisco 857 and Cisco 877 routers are asymmetric digital subscriber line (ADSL)-over-plain old telephone service (POTS) routing devices. The routers have an integrated 4-port Ethernet switch for the LAN and an ADSL physical interface for the WAN, allowing the routers to connect a corporate telecommuter or small office to corporate LANs and the Internet.

The front panels of the Cisco 857 and Cisco 877 routers are identical. (See Figure 1-4.) The back panels of these two routers are similar except for their model numbers, which differ. Figure 1-5 shows the back panel of a Cisco 857 router, and Figure 1-6 shows the back panel of a Cisco 877 router.

Cisco 876 ADSL-over-ISDN Router

The Cisco 876 router is an asymmetric digital subscriber line (ADSL)—over—ISDN routing device. The router has an integrated 4-port Ethernet switch for the LAN and an ADSL physical interface for the WAN, and ISDN BRI WAN connectivity. This ISDN BRI interface can be used for normal WAN connections or can be configured as a backup connection for the ADSL WAN interface. These features allow the routers to connect a corporate telecommuter or a small office to a central office or an Internet service provider (ISP) over an ADSL interface.

Integrated 802.11b/g Radio Module (Wireless Models Only)

The Cisco 850 series and Cisco 870 series wireless routers have an integrated IEEE 802.11b/g radio module that operates as a wireless access point in infrastructure mode. The wireless routers have two

reverse-polarity threaded Neill-Concelman (RP-TNC) connectors on the back panel. The dipole swivel antennas that were shipped with the router connect to the RP-TNC connectors to operate the 802.11b/g radio module.

The wireless operations can be configured by using the Cisco Router and Security Device Manager (SDM) web-based application, or by using the Cisco IOS command-line interface (CLI). See the

Cisco

Router and Security Device Manager (SDM) Quick Start Guide or the Cisco Access Router

Wireless Configuration Guide for more information.

External Power-over-Ethernet Module (Optional)

The optional external power-over-Ethernet (PoE) module is a standalone device that connects to the Ethernet ports on the router on one side (To ROUTER) and to powered devices (such as PCs, laptops, and IP phones) on the other side (To LAN). The PoE module has an independent power source that can provide inline power to devices connected to each of the four Ethernet ports, so that these devices do not need separate power sources.

Caution To ensure proper PoE module operation, do not connect the PoE module power supply to the PoE module

before you connect the PoE module to the router. Do not connect ISDN devices to the Ethernet ports on the PoE module; doing so may damage the hardware.
