C H A P T E R 1 Product Overview The Cisco 837 and SOHO 97 routers are asymmeric digital subscriber line (ADSL)–over–plain old telephone service (POTS) routing devices. They 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 routers support high-speed encryption, the10/100BASE-T switch, and dial backup functionality via the auxiliary console port.
Chapter 1 Product Overview Features Features Table 1-1 summarizes the features of the Cisco 837 and SOHO 97 routers. Table 1-1 Feature Summary for Cisco 837 and SOHO 97 Routers Feature Description 10/100BASE-T Ethernet switch Provides connection to 10BASE-T (10-Mbps) or 100BASE-T (100-Mbps) Ethernet networks. Compatible with 10/100-Mbps devices. ADSL port Provides connection to ADSL network. Does not support auto-switch function.

Chapter 2 Installation Preparing for Installation Preparing for Installation This section provides information on safety, mounting of the router, and unpacking of the router box. Safety This section provides safety warnings and electrostatic and router damage information for the Cisco 837 and SOHO 97 routers. Warnings Before installing the router, read the following warnings: Warning Only trained and qualified personnel should be allowed to install or replace this equipment.
Chapter 2 Installation Preparing for Installation Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. Warning Ultimate disposal of this product should be handled according to all national laws and regulations.
Chapter 2 Installation Preparing for Installation Preventing Electrostatic Discharge Damage Electrostatic discharge (ESD) is a transfer of electrostatic charge between bodies of different electrostatic potentials, such as an operator and a piece of electrical equipment. It occurs when electronic components are improperly handled, and it can damage equipment and impair electrical circuitry. Electrostatic discharge is more likely to occur with the combination of synthetic fibers and dry atmosphere.
Chapter 2 Installation Preparing for Installation Unpacking the Box Table 2-1 lists the items that come with your router. All these items are in the accessory kit that is inside the box that your router came in. If any of the items is missing or damaged, contact your customer service representative.
Chapter 2 Installation Preventing Damage to the Router Note An optional cable used for connecting a Cisco 837 router’s console port to an async modem is available for dial backup and remote management. (The SOHO 97 router does not need this cable.) This SOHO/800 Series Router Modem Cable needs to be ordered separately. Contact your router vendor to order this cable.
Chapter 2 Installation Mounting the Router Mounting the Router You can mount the router on one of the following surfaces: • Table or other horizontal surface • Wall or other vertical surface Mounting on a Table Place the router firmly on a table, and perform the procedure given in the “Installing the Router” section on page 2-10.
