Wiring Procedure for DC Input
To connect the router to a DC power source, perform the following steps:
Step 1 Remove power from the DC circuit. To ensure that power is removed from the DC circuit, locate the circuit breaker for the DC circuit, switch the circuit breaker to the OFF position, and tape the circuit-breaker switch in the OFF position.
Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. Statement 1003
Tip Secure all power cabling when installing this unit to avoid disturbing field-wiring connections.
Step 2 Strip the wires to the appropriate length for the terminals. The strip length is 1/8 to 3/16 inch (3 to 5 mm) for Molex number 19193-0009 and for AMP number 324159-0 terminals.
Step 3 Crimp the terminals to the DC power input wires.
Warning When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the insulation and conductor. Statement 1002
Step 4 Remove the plastic covers from the terminal block. Save them for reinstallation after you finish wiring.
Note Do not remove the colored screw at either end of the terminal block. Those are the terminal mounting screws.
Step 5 Connect the DC power input wires to the terminal block as shown in Figure 8. To avoid interference with the on/off switches, and to bring the wires close to the cable-tie attachment, organize the wires downward from the terminal block.
Warning The illustration shows the DC power supply terminal block. Wire the DC power supply as illustrated. The proper wiring sequence is ground to ground, positive to positive, and negative to negative. The ground wire should always be connected first and disconnected last. Statement 239
Warning An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure that no exposed portion of the DC-input power source wire extends from the terminal block plug. Statement 122
Caution Do not overtorque the terminal block contact screws. Recommended torque is 8.0 ± 0.5 in-lb (0.9 ± 0.05 N-m).
Figure 8 DC Input Power Connections
Step 6 Install the plastic covers over the terminal block. (See Figure 9.)
Warning The safety cover is an integral part of the product. Do not operate the unit without the safety cover installed. Operating the unit without the cover in place will invalidate the safety approvals and pose a risk of fire and electrical hazards. Statement 117
Step 7 Secure the wires using cable ties as shown in Figure 9. The chassis has a cable-tie attachment below and to the right of the terminal block.
Step 8 Turn on power to the DC circuit.

Initial Configuration by Using the Setup Command Facility
This section shows how to use the setup command facility to configure a host name for the router, set passwords, and configure an interface for communication with the management network. If you see the following messages at the end of the startup sequence, the setup command facility has been invoked automatically:
--- 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 '[]'.
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.
Note If you make a mistake while using the setup command facility, you can exit and run the setup command facility again. Press Ctrl-C, and enter setup at the privileged EXEC mode prompt (3600#).
Step 1 To proceed using the setup command facility, enter yes.
Would you like to enter the initial configuration dialog? [yes/no]: yes
Step 2 When the following messages appear, press Return to enter basic management setup:

to configure each interface on the system
Would you like to enter basic management setup? [yes/no]: yes
Step 3 Enter a host name for the router (this example uses 3631):
Configuring global parameters:
Enter host name [Router]: 3631
The enable secret is a password used to protect access to privileged EXEC and configuration modes. This
password, after entered, becomes encrypted in the configuration.
Step 4 Enter an enable secret password. This password is encrypted (more secure) and cannot be seen when viewing the configuration:
Enter enable secret: xxxx
The enable password is used when you do not specify an enable secret password, with some older software
versions, and some boot images.
Step 5 Enter an enable password that is different from the enable secret password. This password is not encrypted (less secure) and can be seen when viewing the configuration:
Enter enable password: xxxx
The virtual terminal password is used to protect access to the router over a network interface.
Step 6 Enter the virtual terminal password, which prevents unauthenticated access to the router through ports other than the console port:
Enter virtual terminal password: xxxx

[0] Go to the IOS command prompt without saving this config.
[1] Return back to the setup without saving this config.
[2] Save this configuration to nvram and exit.
Enter your selection [2]: 2
% You can enter the setup, by typing setup at IOS command prompt
Press RETURN to get started! RETURN
Step 12 The user prompt is displayed:
When you have completed the initial configuration tasks, your Cisco router is ready to configure for specific functions. See the "Where to Go Next" section for information about locating documentation for advanced configuration procedures.
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 '[]'.
Would you like to enter the initial configuration dialog? [yes/no]:
If these messages do not appear, SDM and a default configuration file have been installed on the router at the factory. To use SDM to configure the router, see the "Initial Configuration Using Cisco Router and Security Device Manager" section.
For interface numbering information, see the "Interface Numbering" section.
Step 1 To proceed with manual configuration by using the CLI, enter no:

7 Interface Numbering
Each individual interface (port) on a Cisco 3631 router is identified by number as described in the following sections.
WAN and LAN Interface Numbering
The Cisco 3631 router chassis contains the following WAN and LAN interface types:
•One built-in FastEthernet LAN interface
•Two slots in which you can install WAN interface cards (WICs)
•Two single-width slots (slot 1 and slot 2) in which you can install single-width network modules
The numbering format is Interface-type Slot-number/Interface-number. Two examples are:
•FastEthernet 0/0
•Serial 1/2
The slot numbers are as follows:
•0 for all built-in interfaces
•0 for all WIC interfaces
•1 for interfaces in the lower network module slot
•2 for interfaces in the upper network module slot
Interface (port) numbers begin at 0 for each interface type, and continue from right to left and (if necessary) from bottom to top.
Figure 10 shows an example of interface numbering on a Cisco 3631 router with:
•A WIC in each WIC slot (containing interfaces serial 0/0 and serial 0/1 in physical slot W0, and interface serial 0/2 in physical slot W1)
•A 32-port asynchronous network module in slot 1 (containing interfaces serial 1/0 through serial 1/31)
•An alarm interface controller network module in slot 2 (internally connected to interface serial 2/0)
•One built-in Ethernet 10/100 interface—FastEthernet 0/0
Figure 10 Interface Numbering—Example
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:
–If slot W0 is empty and slot W1 contains a 1-port serial WIC, the interface in the WIC is numbered serial 0/0.
–If slot W0 contains a 2-port serial WIC and slot W1 contains a 1-port serial WIC, the interfaces in physical slot W0 are numbered serial 0/0 and serial 0/1, and the interface in physical slot W1 is numbered serial 0/2.
–If slot W0 contains a 2-port serial WIC and slot W1 contains a 1-port BRI WIC, the interfaces in physical slot W0 are numbered serial 0/0 and serial 0/1, and the interface in physical slot W1 is numbered BRI 0/0.
