Caution If you connect dual DC power sources, both sources must be the same polarity. Do not connect a –DC with a +DC
source to a Cisco 2691 router. Opposite-polarity sources damage the power supply.
DC Wiring Requirements
A Cisco 2691 router with a DC-input power supply requires copper wire for the power connections. Table 2 summarizes the
wiring requirements.
You can connect a single DC power source to either the A input or the B input. If there are dual power sources, connect one
source to the A input and one source to the B input; both sources must be the same polarity and voltage.
Note For installations compliant with the National Electric Code, AWG 14 (2.0 mm2) wire is required for DC input and
safety ground wire.
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 3/16 in. to 1/4 in. (5 mm to 7 mm).
Step 3 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 4 Connect the wires to the terminal block, starting with the safety ground wire. Insert each wire into the appropriate
terminal as shown in Figure 8. To avoid interference with the on/off switch, insert the wires from below. Tighten the
terminal screws to 8.0 ±0.5 in-lb (0.9 ±0.05 N-m).

Power-Up Procedure
To power up your Cisco router and verify that it goes through its initialization and self-test, perform this procedure. When the
procedure is finished, the Cisco router is ready to be configured.
Note To view the boot sequence through a terminal session, you must have a console connection to the Cisco router before
it powers on.
Step 1 Make sure that your PC is powered up and connected as described in the “Checklist for Power-Up” section.
Step 2 Move the power switch to the ON position.
The green POWER or PWR LED on the front of the chassis comes on and the fan operates. If this does not happen, see
the power-up procedure in the Cisco 2600 Series Routers Hardware Installation Guide.
Messages begin to appear in your terminal emulation program window.
Caution Do not press any keys on the keyboard until the messages stop. Any keys pressed during this time are interpreted
as the first command typed when the messages stop, which might cause the router to power off and start over. It
takes a few minutes for the messages to stop.

configure your router using SDM or to learn how to obtain SDM and install it on your router.
•If you see the following messages, the router has booted and is ready for initial configuration using the setup command
facility or the command-line interface (CLI).
--- 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]:
To learn how to use the setup command facility to configure the router, see the “Initial Configuration Using the Setup
Command Facility” section on page 19. To learn how to use the CLI to configure the router, see the “Initial Configuration
Using the CLI (Manual Configuration)” section on page 21.
Note If the rommon 1> prompt appears, your system has booted in ROM monitor mode. For information on the ROM
monitor, see the router rebooting and ROM monitor information in the Cisco IOS Configuration Fundamentals
Configuration Guide for your Cisco IOS software release.
You can access this document at the locations described in the “Where to Go Next” section on page 23.
6 Perform Initial Configuration
You can configure your router by using one of the following methods:
•Cisco Router and Security Device Manager (SDM)—If your router was purchased with a VPN bundle, SDM is installed on
the router. For instructions on configuring your router by using SDM, refer to the Cisco Router and Security Device
Manager (SDM) Quick Start Guide that shipped with your router. See the “Initial Configuration Using Cisco Router and
Security Device Manager” section on page 19 for additional information.
•Setup command facility—You can use the setup command facility to configure basic router information. After the
configuration file has been created, you can use the CLI or SDM to perform additional configuration. See the “Initial
Configuration Using the Setup Command Facility” section on page 19 for additional information.
•Command-line interface (CLI)—If you prefer to use the Cisco IOS CLI, see the “Initial Configuration Using the CLI
(Manual Configuration)” section on page 21 for instructions on how to use the CLI.
Note You need to understand how interfaces are numbered so that you know which interface you are configuring. If you need
help with interface and port numbering, see the “Interface Numbering” section on page 22.

Initial Configuration Using Cisco Router and Security Device Manager
If the following messages appear at the end of the startup sequence, Cisco Router and Security Device Manager (SDM) is
installed on your router:
yourname con0 is now available
Press RETURN to get started.
For instructions on configuring your router by using SDM, refer to the Cisco Router and Security Device Manager (SDM) Quick
Start Guide.
Tip If the messages above do not appear, SDM and the Cisco Router and Security Device Manager (SDM) Quick Start Guide
were not shipped with your router. If you want to use SDM, you can download the latest version of SDM and
instructions for installing it on your router from the following location:
http://www.cisco.com/pcgi-bin/tablebuild.pl/sdm
To obtain the SDM quick start guide, SDM release notes, and other SDM documentation, go to www.cisco.com/go/sdm
and click the Technical Documentation link.
Initial Configuration 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 on page 22.
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 (2691#).
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:
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 '[]'.
Basic management setup configures only enough connectivity
for management of the system, extended setup will ask you
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 2691):
Configuring global parameters:
Enter host name [Router]: 2691
Step 4 Enter an enable secret password. This password is encrypted (more secure) and cannot be seen when viewing the
configuration:
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.
Enter enable secret: xxxxxx
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:
The enable password is used when you do not specify an
enable secret password, with some older software versions, and
some boot images.
Enter enable password: xxxxxx
Step 6 Enter the virtual terminal password, which prevents unauthenticated access to the router through ports other than the
console port:
The virtual terminal password is used to protect
access to the router over a network interface.
Enter virtual terminal password: xxxxxx
Step 7 Respond to the following prompts as appropriate for your network:
Configure SNMP Network Management? [yes]:
Community string [public]:
Step 8 A summary of the available interfaces is displayed:
Note The interface numbering that appears is dependent on the type of Cisco modular router platform and on the
installed interface modules and cards.
Current interface summary
Controller Timeslots D-Channel Configurable modes Status
T1 0/0 24 23 pri/channelized Administratively up
Any interface listed with OK? value "NO" does not have a valid configuration
Interface IP-Address OK? Method Status Prol
FastEthernet0/0 unassigned NO unset up up
FastEthernet0/1 unassigned NO unset up dow
Step 9 Select one of the available interfaces for connecting the router to the management network:
Enter interface name used to connect to the
management network from the above interface summary: fastethernet0/0
Step 10 Respond to the following prompts as appropriate for your network:
Configuring interface FastEthernet0/0:
Use the 100 Base-TX (RJ-45) connector? [yes]: yes
Operate in full-duplex mode? [no]: no
Configure IP on this interface? [yes]: yes
IP address for this interface: 172.1.2.3
Subnet mask for this interface [255.255.0.0] : 255.255.0.0
Class B network is 172.1.0.0, 16 subnet bits; mask is /16
