ISRs. Legacy CF will not operate in these routers. When legacy CF is inserted, the following error
message appears:
WARNING: Unsupported compact flash detected. Use of this card during
normal operation can impact and severely degrade performance of the
system. Please use supported compact flash cards only.
2. HWICs, WICs, and VWICs (data only) are supported.
3. Non wireless models only.
Memory
Cisco 1900 series routers contain the following types of memory:
DRAMStores the running configuration and routing tables and is used for packet buffering by the
network interfaces. Cisco IOS software executes from DRAM memory.
Boot/NVRAMInternal flash memory. Stores the bootstrap program (ROM monitor), the
configuration register, and the startup configuration.
Flash memoryExternal flash memory (1940 series only). Stores the operating system software
image.
Table 1-3 summarizes the memory options for Cisco 1900 series routers. The default memory numbers
for RAM represent the minimum usable memory. You can install additional RAM in multiples of the

Chassis Ventilation
An internal fan provides chassis cooling. An onboard temperature sensor controls the fan speed. The fan
is always on when power is applied to the router. Under most conditions, the fan operates at the slowest
speed to conserve power and reduce fan noise. It operates at the higher speeds when necessary under
conditions of higher ambient temperature. See the Chassis Airflow Diagram section on page 4-3.
Real-Time Clock
An internal real-time clock with battery backup provides the system software with time of day on system
power up. This allows the system to verify the validity of the certification authority (CA) certificate. The
Cisco 1900 series router has a lithium battery. This battery lasts the life of the router under the operating
environmental conditions specified for the router, and is not field-replaceable.
Note
If the lithium battery in a Cisco 1900 ISR should fail, the router must be returned to Cisco for repair.
Although the battery is not intended to be field-replaceable, the following warning must be heeded:
Warning
Chassis Security
The chassis of the router is constructed with a KensingtonTM security slot on the back panel. It can be
secured to a desktop or other surface by using KensingtonTM lockdown equipment.

The wireless access point does not have an external console port for connections. To configure the
wireless device, you must use a console cable to connect a PC to the host routers console port as
described in Chapter 3, Cable Information and Specifications for Cisco 1900 Series Routers, and then
use the Cisco IOS command-line interface (CLI) to access the interface.
Table 1-5 describes the radios and antennas for the Cisco 1900 series wireless routers.

Interface Numbering
Each individual interface (port) on a Cisco 1900 series router is identified by a number. The Cisco 1900
series routers contains the following wide-area network (WAN) and local-area network (LAN) interface
types:
Two slots in which you can install WICs, VWICs (data only), and HWICs. The Cisco 1905 comes
with a factory installed EHWIC in the right slot.
The numbering format for the slots is interface-type 0/slot-number/interface-number. Table 1-6
summarizes the interface numbering. See Figure 1-5 to identify the slot numbers.

On the Cisco 1900 series router, the numbering format for configuring an async interface is 0/slot/port. To
configure the line associated with an async interface, simply use the interface number to specify the
async line. For example, line 0/0/0 specifies the line associated with interface serial 0/0/0 on a WIC-2A/S
in slot 0. Similarly, line 0/1/1 specifies the line associated with interface async 0/1/1 on a WIC-2AM in

Safety Recommendations
General Guidelines
Follow these guidelines to ensure general safety:
Keep the chassis area clear and dust-free during and after installation.
Do not wear loose clothing that could get caught in the chassis. Fasten your tie or scarf, and roll up
your sleeves.
Wear safety glasses when working under conditions that might be hazardous to your eyes.
Do not perform any action that creates a hazard to people or makes the equipment unsafe.
2-1
Chapter 2
Safety Recommendations
Warning
Read the installation instructions before connecting the system to the power source. Statement 1004
Warning
Blank faceplates and cover panels serve three important functions: they prevent exposure to
hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI)
that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not
operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement
1029
Warning
To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the
handles on modules (such as power supplies, fans, or cards); these types of handles are not designed
to support the weight of the unit. Statement 1032
Warning
Ultimate disposal of this product should be handled according to all national laws and regulations.
Statement 1040
Warning
Do not work on the system or connect or disconnect cables during periods of lightning activity.
Statement 1001
Warning
Read the installation instructions before connecting the system to the power source. Statement 1004
Warning
When installing or replacing the unit, the ground connection must always be made first and
disconnected last. Statement 1046
Locate the emergency power-off switch in the room in which you are working. Then, if an electrical
accident occurs, you can quickly turn off the power.
Look carefully for possible hazards in your work area, such as moist floors, ungrounded power
extension cables, frayed power cords, and missing safety grounds.
2-2
OL-19084-02
Chapter 2
Never install telephone jacks in wet locations unless the jack is specifically designed for it.
Never touch uninsulated telephone wires or terminals unless the telephone line is disconnected at
the network interface.
Caution
Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to
an unpainted surface of the chassis frame to channel unwanted ESD voltages safely to ground. To
guard against ESD damage and shocks, the wrist strap and cord must operate effectively.
If no wrist strap is available, ground yourself by touching a metal part of the chassis.
For the safety of your equipment, periodically check the resistance value of the antistatic strap. It should
be between 1 and 10 megohms (Mohm).
2-3
Chapter 2
Warning
The device is designed for connection to TN and IT power systems. Statement 1007
All units include a 6-foot (1.8-meter) electrical power cord. (A label near the power cord indicates
the correct voltage, frequency, current draw, and power dissipation for the unit.)
Site Environment
The Cisco 1900 series router is designed for placement on a desktop, rack-mounted or wall mounted.
The location of your router is an extremely important consideration for proper operation. Equipment
placed too close together, inadequate ventilation, and inaccessible panels can cause malfunctions and
shutdowns, and can also make maintenance difficult. Plan for access to both front and back panels of the
router.
When planning your site layout and equipment locations, remember the precautions described in the
Site Configuration section on page 2-4 to help avoid equipment failures and reduce the possibility of
environmentally caused shutdowns. If you are currently experiencing shutdowns or an unusually high
number of errors with your existing equipment, these precautions may help you isolate the cause of the
failures and prevent future problems.
Site Configuration
The following precautions will help you plan an acceptable operating environment for your router and
will help you avoid environmentally caused equipment failures:
Make sure that the room where your router operates has adequate circulation. Electrical equipment
generates heat. Without adequate circulation, ambient air temperature may not cool equipment to
acceptable operating temperatures. See the Chassis Airflow Diagram section on page 4-3.
Always follow the ESD-prevention procedures described in the Preventing Electrostatic Discharge
Damage section on page 2-3 to avoid damage to equipment. Damage from static discharge can
cause immediate or intermittent equipment failure.
Make sure that the chassis cover and module back panels are secure. All empty interface card slots
must have filler panels installed. The chassis is designed to allow cooling air to flow within it,
through specially designed cooling slots. A chassis with uncovered openings creates air leaks, which
may interrupt and reduce the flow of air across internal components.

4-11
Chapter 4
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. Statement 1021
Warning
Hazardous network voltages are present in WAN ports regardless of whether power to the router is
OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching
cables, detach the end away from the router first. Statement 1026
Warning
Blank faceplates and cover panels serve three important functions: they prevent exposure to
hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI)
that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not
operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement
1029
Warning
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into
beams or view directly with optical instruments. Statement 1051
Warning
Do not locate the antenna near overhead power lines or other electric light or power circuits, or
where it can come into contact with such circuits. When installing the antenna, take extreme care
not to come into contact with such circuits, because they may cause serious injury or death. For
proper installation and grounding of the antenna, please refer to national and local codes (for
example, U.S.:NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code,
Section 54). Statement 1052
Warning
Warning
Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do
not view directly with optical instruments. Viewing the laser output with certain optical instruments
(for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye
hazard. Statement 1056
Warning
Before opening the unit, disconnect the telephone-network cables to avoid contact with
telephone-network voltages. Statement 1041
Warning
This equipment contains a ring signal generator (ringer), which is a source of hazardous voltage. Do
not touch the RJ-11 (phone) port wires (conductors), the conductors of a cable connected to the RJ-11
port, or the associated circuit-board when the ringer is active. The ringer is activated by an incoming
call. Statement 1042

You have a PC with a terminal emulation program (HyperTerminal or equivalent) that is connected
to the console port. It is configured for 9600 baud, 8 data bits, 1 stop bit, no parity, and flow control
is set to none.
You have selected a suitable PC COM port in the terminal emulation program.
You have determined the IP addresses for the Ethernet and serial interfaces.
Note
To view the boot sequence, you must establish console connection to the Cisco router before it powers
up.
Before You Begin
Make sure that your PC is ready to be powered up and connected as described in the Checklist
Before Powering Up the Cisco Router section on page 5-1.
Procedure
Step 1
The SYS LED on the front of the chassis begins blinking green.
Startup messages appear in your console window. When the startup messages finish, the SYS LED
appears solid green.
Depending on your installation, some LEDs at the rear of the chassis and on installed modules might
also illuminate.
Caution
Do not press any keys on the keyboard until the messages stop and the SYS LED is solid green.
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.

Chapter 5
Note
Cisco recommends using Cisco Configuration Professional Express to perform the initial configuration
on the router because it provides a web-based graphical-user interface (GUI).
If the system configuration dialog message does not appear, a default configuration file was installed on
the router prior to shipping. See the Using Cisco Configuration Professional Express section on
page 5-6 to configure the router.
The setup command facility prompts you to enter the information that is needed to configure a router
quickly. The facility steps you through a initial configuration, including LAN and WAN interfaces. For
more general information about the setup command facility, see Cisco IOS Configuration Fundamentals
Configuration Guide, Release 12.4.
Note
The messages that are displayed will vary based 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.
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 the setup command in privileged EXEC mode
(Router#).
5-3
Chapter 5
Procedure
Step 1
Enter the setup command facility. From the Cisco IOS CLI, enter the setup command in privileged
EXEC mode, enter the following:
Router> enable
Password: <password>
Router# setup
--- System Configuration Dialog --Continue with configuration dialog? [yes/no]:
Step 2
Step 3
Proceed using basic management setup, which configures only enough connectivity:
Would you like to enter basic management setup? [yes/no]: yes
Step 4
Step 5
Enter an enable secret password. This password is encrypted (for more security) 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: cisco
Step 6
Enter an enable password that is different from the enable secret password. This password is not
encrypted (and is 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: cisco123
Step 7
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: cisco

IP Routing
You can configure integrated routing and bridging (IRB) so the router can route and bridge
simultaneously. The router will act as an IP host on the network whether routing is enabled or not. To
read more about IRB see the following URL on Cisco.com,
http://www.cisco.com/en/US/tech/tk389/tk815/tk855/tsd_technology_support_sub-protocol_home.html
IP routing is automatically enabled in the Cisco IOS software. When IP routing is configured, the system
will use a configured or learned route to forward packets, including a configured default route.
Note
This task section does not apply when IP routing is disabled. To specify a default route when IP routing
is disabled, refer to the Configuring a Gateway of Last Resort Using IP Commands tech note.
Default Routes
A router might not be able to determine the routes to all other networks. To provide complete routing
capability, the common practice is to use some routers as smart routers and give the remaining routers
default routes to the smart router. (Smart routers have routing table information for the entire
internetwork.) These default routes can be passed along dynamically, or can be configured into the
individual routers.
Most dynamic interior routing protocols include a mechanism for causing a smart router to generate
dynamic default information that is then passed along to other routers.
Default Network
If a router has an interface that is directly connected to the specified default network, the dynamic
routing protocols running on the router will generate or source a default route. In the case of RIP, the
router will advertise the pseudonetwork 0.0.0.0. In the case of IGRP, the network itself is advertised and
flagged as an exterior route.
A router that is generating the default for a network also may need a default of its own. One way a router
can generate its own default is to specify a static route to the network 0.0.0.0 through the appropriate
device.
