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).

This chapter describes the features and specifications of the routers and includes the following sections:
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.
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
Note The serial number for the Cisco 1800 series fixed-configuration routers is 11 characters long.
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:

Table 1-1 summarizes the built-in ports and other hardware features of the Cisco 1800 series fixed-configuration routers.
Cisco 1800 series fixed-configuration routers contain the following types of memory:
•DRAM—Stores the running configuration and routing tables and is used for packet buffering by the network interfaces. Cisco IOS software executes from DRAM memory.Cisco 1800 series fixed-configuration routers contain 128 MB of internal DRAM memory by default. Cisco 1800 series fixed-configuration router models also contain a single 200-pin DDR Small Outline DIMM (SODIMM) slot that can accommodate up to a 256-MB SODIMM, for a maximum of 384 MB of internal DRAM memory.
•NVRAM—Internal flash memory. Stores the bootstrap program (ROM monitor), the configuration register, and the startup configuration. All Cisco 1800 series fixed-configuration models contain 2 MB of boot/NVRAM memory by default.
•Flash memory—External CompactFlash memory. Stores the operating system software image. All Cisco 1800 series fixed-configuration models contain 32 MB of internal flash memory by default, and can use external CompactFlash cards up to 128 MB in capacity.
Table 1-2 summarizes the AC power options for the Cisco 1800 series fixed-configuration routers.
Table 1-3 summarizes the LED indicators that are located in the router front panel.

1 Inline power is a field-upgradable option only. It is not installed by default. 2 This LED does not exist on the Cisco 1812. 3 This LED exists on the Cisco 1801, Cisco 1802, and Cisco 1803 only. 4 This LED does not exist on the Cisco 1811. 5 This LED exists on the Cisco 1811 only. |
For LED troubleshooting information, including possible trouble causes and corrective actions, see Table 6-1 in the "Troubleshooting" chapter.
The Cisco 1800 series fixed-configuration routers with the wireless option have an integrated IEEE 802.11a/b/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 802.11a/b/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.
Table 1-4 lists the Cisco antennas that are supported on the Cisco 1800 series fixed-configuration wireless routers.

Cisco 1800 series fixed-configuration routers have an internal multispeed fan that provides chassis cooling, controlled by an onboard temperature sensor. The internal fan operates at a continuously variable speed to minimize fan noise while providing sufficient chassis cooling.
An internal real-time clock with battery backup provides the system software with time of day on system power up. This allows the system to verify the validity of the certification authority (CA) certificate and to timestamp syslog messages. Cisco 1800 series fixed-configuration routers have a socketed lithium battery. This battery lasts the life of the router under the operating environmental conditions specified for the router; the battery is not field-replaceable.
Note If the lithium battery in a Cisco 1800 series fixed-configuration router fails, the router must be returned to Cisco for repair.
Although the battery is not intended to be field-replaceable, the following warning must be heeded:
Warning There is the danger of explosion if the battery is replaced incorrectly. Replace the battery only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instructions. Statement 1015
All Cisco 1800 series fixed-configuration routers include a Kensington lock located at the top left corner of the back panel for physical security.
This section contains views of the front and rear panels of the Cisco 1800 series fixed-configuration routers, showing locations of the power and signal interfaces, module slots, status indicators, and chassis identification labels.
