The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class
A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate
radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television
reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in
part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation.
However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class
A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct
any interference to radio or television communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco
equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by
using one or more of the following measures:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
• Move the equipment farther away from the television or radio.
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television
or radio are on circuits controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has
established severity definitions.
Severity 1 (S1)—Your network is “down,” or there is a critical impact to your
business operations. You and Cisco will commit all necessary resources around
the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or
significant aspects of your business operation are negatively affected by
inadequate performance of Cisco products. You and Cisco will commit full-time
resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most
business operations remain functional. You and Cisco will commit resources
during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product
capabilities, installation, or configuration. There is little or no effect on your
business operations.

Product Overview
The Cisco 831 router and Cisco SOHO 91 Ethernet-to-Ethernet routers can
connect a corporate telecommuter or small office to an Internet service provider
(ISP) over a broadband or Ethernet connection to the following sites:
•
Corporate LANs
•
The Internet
The Cisco 831 and SOHO 91 routers are switch-capable routers that provide a
4-port Ethernet switch for the LAN. The routers are capable of bridging and
multiprotocol routing between LAN and WAN ports.
Cisco 831 and SOHO 91 routers support high-speed encryption, 10/100-Mbps
switching, and dial backup functionality via the auxiliary console port. The
autosensing function in the routers eliminates the need for a crossover cable and
allows the routers to detect the medium dependent interface in normal mode
(MDI) or medium dependent interface in crossover mode (MDIX) in any other
PC/hub with a straight-through cable or crossover cable.
The dial backup function allows the user to connect an analog modem to the
console port as a backup link to the WAN in case the ADSL service goes down.
These features give the Cisco 831 and SOHO 91 routers a high level of
performance and security.
The Cisco 831 router is designed with hardware-based encryption, while the
Cisco SOHO 91 supports software-based encryption. The Cisco 831 router
supports the ability to add Flash memory or SDRAM, either as a factory upgrade
or a field-installed option. The SOHO 91 router has a fixed memory configuration.

voltage (SELV) circuits. SELV circuits should only be connected to other SELV
circuits. Avoid connecting these circuits to telephone network voltage (TNV)
circuits.
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
Do not work on the system or connect or disconnect cables during periods of
lightning activity.
Warning
This equipment is not designed for making emergency telephony calls when the

Preparing for Installation
Warning
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line
cord.
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.
Warning
During this procedure, wear grounding wrist straps to avoid ESD damage to the
card. Do not directly touch the backplane with your hand or any metal tool, or
you could shock yourself.
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 in the presence of synthetic fibers and dry atmosphere.
Always use the following ESD-prevention procedures when removing and
replacing components:
Step 1
Wear an ESD-preventive wrist strap that you provide, ensuring that it makes good
skin contact.
Caution
To properly guard against ESD damage and shocks, the wrist strap and cord must
operate effectively. Always follow the guidelines in the preceding section,
“Warnings.”
Step 2
Do not touch any exposed contact pins or connector shells of interface ports that
do not have a cable attached.

switch ports (1, 2, 3, or 4).
Step 2
Open a web browser. Make sure that the browser is set to work in online mode.
Step 3
•
In Internet Explorer, click the File menu, and verify that the “work offline”
option is unchecked.
•
In Netscape, the default selection in the File menu is set to work online.
Enter the following universal resource locator (URL):
http://10.10.10.1
Tip
If the CRWS home page does not appear when you enter the URL
http://10.10.10.1, test the connection between the PC and the router by doing
the following:
1.
Check that the OK LED on the router is on, and check the cable connection
between the router and the PC.
2.
If the CRWS home page still does not appear, verify that the web browser’s
“work offline” option is disabled.
3.
If the web page still does not appear, verify that the PC is automatically
configured to receive an IP address. Follow the instructions in the
Cisco Router Web Setup User Guide, which is available on Cisco.com.

4.
If the PC is configured to automatically receive an IP address, but the web
page still does not appear, select Start/Run, type winipcfg in the Run
window, and examine the address in the IP address field. The address should
be in the format 10.10.10.X, in which X is a number that is 2 or greater; for
example, 10.10.10.2 or 10.10.10.3. If the IP address is not in this format,
verify that an Ethernet adapter name is visible in the Adapter field. If it is not,
return to Step 3 in the “Checking the PC Configuration” section on page 2-16
and add TCP to the list of protocols. Then return to the beginning of the
“Starting the CRWS Software” section on page 2-22, and complete the
procedure.
Step 4
Click the Router Setup link in the Cisco Router Web Setup home page, and
follow the instructions that appear in the page that is displayed.
Step 5
When you complete setup using CRWS, connect to another website, using the
connected PC. If you successfully connect to the website, then setup is complete,
and you can continue using the router.
