CH A P T E R 1-1 Cisco 1800 Series Integrated Services Routers (Fixed) Hardware Installation Guide OL-6425-03 1 Overview The Cisco 1800 series fixed-configuration routers are part of the new line of integrated services routers that are optimized for secure, fast, high-quality delivery of multiple, concurrent services for small-to-medium-sized businesses and small enterprise branch offices. The Cisco 1811 and Cisco 1812 routers offer an 8-port 10/100Base-T switch, dual 10/100Base-T WAN ports, two USB 2.0 ports, and either an ISDN S/T or an analog modem port. The Cisco 1801, Cisco 1802, and Cisco 1803 routers offer an 8-port 10/100Base-T switch; a single 10/100Base-T WAN port; an ISDN S/T port; and either an ADSL over POTS, ADSL over ISDN, or G.SHDSL WAN port. All models also offer embedded hardware-based encryption that provides superior performance for advanced applications, optional 802.11a/b/g wireless LAN functionality, an integrated real-time clock for validating digital certificates and stamping syslog entries, and optional Power over Ethernet (PoE). Figure 1-1 shows a front view of a Cisco 1800 series fixed-configuration router.

1-2 Cisco 1800 Series Integrated Services Routers (Fixed) Hardware Installation Guide OL-6425-03 Chapter 1 Overview Hardware Features Hardware Features This section describes the basic features of the Cisco 1800 series fixed-configuration routers, including product identification, built-in interfaces, memory, LED indicators, chassis ventilation, and the internal clock. Product Serial Number Location On the Cisco 1800 series fixed-configuration routers, the serial number label is located on the back of the chassis, along the bottom edge near the lower right corner. (See Figure 1-2.) Figure 1-2 Serial Number Location NoteThe serial number for the Cisco 1800 series fixed-configuration routers is 11 characters long. Cisco Product Identification Tool The Cisco Product Identification (CPI) tool provides detailed descriptions and illustrations showing where to locate serial number labels on Cisco products. The CPI tool includes the following features: A search option allows browsing for models by using a tree-structured product hierarchy. A search field on the final results page makes it easier to look up multiple products. End-of-sale products are clearly identified in results lists. The tool streamlines the process of locating serial number labels and identifying products. Serial number information expedites the entitlement process and is important for access to support services. The Cisco Product Identification tool can be accessed at the following URL: http://tools.cisco.com/Support/CPI/index.do Feature Summary Ta b l e 1-1 summarizes the built-in ports and other hardware features of the Cisco 1800 series fixed-configuration routers. 127166, 781-00302-01 SN: XXXNNNNXXXX SN: XXXNNNNXXXX
1-3 Cisco 1800 Series Integrated Services Routers (Fixed) Hardware Installation Guide OL-6425-03 Chapter 1 Overview Hardware Features Memory Cisco 1800 series fixed-configuration routers contain the following types of memory: Ta b l e 1-1 Summary of Cisco 1800 Series Fixed-Configuration Built-In Interfaces FeatureDescription Managed 8-port 10/100 Fast Ethernet switchProvides connection to 10/100BASE-T (10/100-Mbps) Ethernet networks. Compatible with 10/100-Mbps devices. 10/100 Fast Ethernet (FE) WAN portProvides connection to 10/100BASE-T Ethernet networks. Can be connected to other network devices, such as cable modem, ADSL, and router. Cisco 1801, Cisco 1802, and Cisco 1803 routers have one 10/100 FE WAN port. Cisco 1811 and Cisco 1812 routers have two 10/100 FE WAN ports. ADSL-over-POTS portCisco 1801 router only. Provides connection to an ADSL network. Does not support the autoswitch function. ADSL-over-ISDN portCisco 1802 router only. Provides connection to an ADSL-over-ISDN network. Does not support the autoswitch function. G.SHDSL portCisco 1803 router only. Provides 2-wire or 4-wire connection to a G.SHDSL network. ISDN S/T portCisco 1801, Cisco 1802, Cisco 1803, and Cisco 1812 routers only. Should the main WAN link go down, provides dial backup and remote management functions by connecting to an ISDN service provider. V.92 analog modem port.Cisco 1811 routers only. Should the main WAN link go down, provides dial backup and remote management functions. Console portProvides a connection to the terminal or PC for software configuration or troubleshooting using the command-line interface (CLI). Auxiliary portProvides a connection to a modem for software configuration or troubleshooting using the command-line interface (CLI). Two USB portsCisco 1811 and Cisco 1812 routers only. Support Cisco USB flash memory modules and USB eToken modules. Integrated 802.11a/b/g radio moduleWireless models only. Provides connectivity to a wireless LAN using IEEE 802.11a/b/g standards. Enables the router to act as an access point (AP) in infrastructure mode. Internal Power-over-Ethernet (PoE) module(Optional) Provides inline power for powered devices, such as IP phones, that are connected to the router. Dying gaspDetects whether the router is about to lose power, and sends a signal to warn the digital subscriber line access multiplexer (DSLAM) about the impending line drop. Wall-mount featureBrackets for mounting the router on a wall or vertical surface. Kensington security slotAllows the router to be secured to a desktop or other surface by using Kensington lockdown equipment. Autosensing functionEliminates the need for a crossover cable and allows the router to detect medium-dependent interface in normal mode (MDI) or medium-dependent interface in crossover mode (MDIX) in any other PC or hub with a straight-through cable or a crossover cable. The router is capable of bridging and multiprotocol routing between the LAN and WAN ports.
