THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT
NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT
ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR
THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION
PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO
LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

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.

Router Memory

This section describes the types of memory stored in the router and how to find
out how much of each the router has.

For instructions on how to upgrade memory in the router, refer to the “Installing
and Upgrading Memory and Data Modules” appendix in this guide.

Types of Memory

The router has the following types of memory:

• Dynamic RAM (DRAM)—This is the main storage memory for the router.

DRAM is also called working storage and contains the dynamic configuration
information. The router stores a working copy of Cisco IOS software,
dynamic configuration information, and routing table information in DRAM.

• Nonvolatile RAM (NVRAM)—This type of memory contains the startup

configuration.

• Flash memory—This special kind of erasable, programmable memory

contains a copy of the Cisco IOS software. The Flash memory structure can
store multiple copies of the Cisco IOS software. You can load a new level of
the operating system in every router in your network and then, when
convenient, upgrade the whole network to the new level. The Flash memory
on the router is stored on mini-Flash modules.

Amounts of Memory

Use the show version command to view the amount of DRAM, NVRAM, and
Flash memory stored in your router. The following example shows the output of
the show version command. The bold text displays the amount of memory stored
in this router.

• Power supply

• DB-25 to DB-9 adapter

• Console cable, RJ-45 to DB-9 (light blue)

• Product documentation

Additional Required Equipment

Depending on your local network and which Cisco WICs and VICs you install in
your router, you might need other items listed in Table 6 to complete your router
installation.

Unpacking the Router

Table 6 Additional Required Equipment

Equipment When You Use It

Ethernet hub A hub connects pieces of network equipment (including the router)

to create a network. You can use a 10-, 100-, or 10/100-Mbps hub
with the router.

Ethernet switch A switch connects pieces of network equipment (including the

router) to create a network. You can use a 10-, 100-, or 10/100-Mbps
switch with the router.

Phillips screwdriver Although the WICs and VICs use thumbscrews, you might need a

Phillips screwdriver to loosen the WIC and VIC cover.

Cisco WIC To make a WAN connection, the router must have a supported WIC

installed. The router supports up to two cards. You can either order
the cards when ordering the router, and they will be installed for
you, or you can order the cards separately, after receiving the router,
and install them yourself.

Additional Required Equipment

Table 6 Additional Required Equipment (continued)

Equipment When You Use It

Cisco VIC To make a voice connection, the router must have a supported VIC

installed. The router supports up to three cards. You can either order
the cards when ordering the router, and they will be installed for
you, or you can order the cards separately, after receiving the router,
and install them yourself.

Straight-through
RJ-45-to-RJ-45 cable

This cable connects the router to the Ethernet LAN and the WICs to
various WAN services, including ISDN, T1/FT1, and 56-kbps
services. You will need one cable for each of these connections.

Standard RJ-11 telephone
cable

This cable connects the VIC to a telephone, fax machine, or a
telephone wall-jack. You will need one cable for each of these
connections.

Standard RJ-48 telephone
cable
