Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security. Statement 1017 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.
Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.

Grounding the Chassis You must connect the chassis to a reliable earth ground; the ground wire must be installed in accordance with local electrical safety standards. • For NEBS-compliant grounding, use size AWG 6 (13 mm2) wire and the ground lug provided in the accessory kit. • For NEC-compliant grounding, use size AWG 14 (2 mm2) or larger wire and an appropriate user-supplied ring terminal.
System Management Connections The connections described in Table 1 provide system management access. Table 1 System Management Connections Port Color Connection: Cable Console Light blue PC or ASCII terminal communication port (usually labeled COM) RJ-45-to-DB-9 adapter cable Auxiliary Black Modem for remote access RJ-45-to-DB-25 adapter cable Power Connections Warning Note Read the installation instructions before connecting the system to the power source.
Note Table 2 For installations compliant with the National Electric Code, AWG 14 (2.0 mm2) wire is required for DC input and safety ground wire.

WAN, LAN, and Voice Connections The connections and cables listed here are described in detail in the following documents: • Cisco 3700 Series Routers Hardware Installation Guide • Cisco Network Modules Hardware Installation Guide • Cisco Interface Cards Installation Guide • Cisco Modular Access Router Cable Specifications For information about accessing these documents, see the “Where to Go Next” section on page 25. Table 3 summarizes some typical WAN, LAN, and voice connections for Cisco 3725 routers.
• Power and interface cables are connected. • Your PC terminal emulation program is configured for 9600 baud, 8 data bits, 1 stop bit, and no parity. • You have selected passwords for access control. • You have determined the IP addresses for the Ethernet and serial interfaces.
Use ctrl-c to abort configuration dialog at any prompt. Default settings are in square brackets '[]'. Would you like to enter the initial configuration dialog? [yes/no]: To learn how to use the setup command facility to configure the router, see the “Initial Configuration Using Setup Command Facility” section on page 20. To learn how to use the CLI to configure the router, see the “Initial Configuration Using the CLI (Manual Configuration)” section on page 23.
Would you like to enter the initial configuration dialog? [yes/no]: The setup command facility prompts you for basic information about your router and network, and it creates an initial configuration file. The prompts vary, depending on your router model, the installed interface modules, and the software image. The following example and the user entries (in bold) are shown as examples only. For interface numbering information, see the “Interface Numbering” section on page 24.

Initial Configuration Using the CLI (Manual Configuration) This section shows how to bring up a command-line interface (CLI) prompt for configuration using the CLI, and it directs you to documentation for the CLI configuration. You can use the CLI if you see the following messages at the end of the startup sequence: --- System Configuration Dialog --At any point you may enter a question mark '?' for help. Use ctrl-c to abort configuration dialog at any prompt. Default settings are in square brackets '[]'.
7 Interface Numbering Each individual interface (port) on a Cisco 3725 router is identified by number as described in the following sections.
Note The slot number for all WIC interfaces is always 0. (The W0 and W1 slot designations are for physical slot identification only.) Interfaces in the WICs are numbered from right to left, starting with 0/0 for each interface type, regardless of which physical slot the WICs are installed in. Some examples are as follows: • If slot W0 is empty and slot W1 contains a 1-port serial WIC, the serial interface in the WIC is numbered Serial 0/0.
