C H A P T E R 8-1 Cisco 1805 DOCSIS Cable Router Hardware Installation Guide OL-14661-01 8 Installing and Upgrading Internal Modules in Cisco 1805 Cable Routers This chapter describes how to install or upgrade modules that are located internally within the Cisco 1805 DOCSIS cable router: memory modules and advanced integration modules (AIMs). You need to remove the cover from the router to install or remove any of these items. The chapter contains the following sections: • Safety Warnings, page 8-1 • Modules Internal to the Cisco 1805 Cable Router, page 8-2 Note Before you install, operate, or service the system, read the Regulatory Compliance and Safety Information for Cisco 1840 Routers for important safety information and translations of the warnings that appear in this guide. Safety Warnings Warning Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord. Statement 1 Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. Statement 43 Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself. Statement 94 Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001

Page 1 of 10 Cisco 1805 Integrated Services Router Product Overview The Cisco® 1805 Integrated Services Router (Figure 1) offers cable multiservice operators (MSOs) a cost-effective, standards-based, integrated cable router solution for business-class broadband services. Designed for small office, home office, and teleworker environments, the Cisco 1805 complies with DOCSIS® 2.0 and delivers secure data networking over hybrid fiber-coaxial (HFC) cable. The Cisco 1805 allows cable MSOs to simplify their customer-premises-equipment (CPE) deployment by consolidating a multibox deployment into a single-box, integrated solution and maximize revenue by offering multiple services. Figure 1. Cisco 1805 Integrated Services Router The Cisco 1805 is the latest addition to the Cisco integrated services router portfolio, which delivers multiple services, including feature-rich Cisco IOS® Software routing, LAN switching, and advanced security with secure cable WAN access technology. The Cisco 1805 with the HFC offers a cost-effective alternative to leased lines; it also can be used to supplement leased-line or other broadband services such as xDSL services for critical WAN backup solutions. Cable service providers and small business customers can also benefit from ease of deployment and management by deploying an integrated, single-box cable solution, including improved quality-of-service (QoS) enforcement, enhanced WAN failover implementation, and improved availability. The Cisco 1805 includes the following: ● Integrated cable modem based on DOCSIS 2.0 ● Built-in encryption hardware that you can enable with optional Cisco IOS Software for Triple Digital Encryption Standard (3DES) and Advanced Encryption Standard (AES) encryption support ● Integrated dual high-speed Fast Ethernet ports that you can use for LAN or WAN connectivity ● Four-port 10/100 Ethernet switch, fully manageable with IEEE 802.1q VLAN support ● Auxiliary (AUX) port (up to 115.2-kbps asynchronous serial) for analog dial backup or out- of-band management ● Console port transmit and receive rates up to 115.2 kbps (default 9600 bps, not a network data port)
