About This Guide
This section discusses the objectives, audience, organization, and conventions of this
hardware installation and configuration guide.
Objectives
This publication will step you through the initial site preparation and installation of the
router. Troubleshooting, maintenance procedures, and cable specifications are also
provided.
Although minimum software configuration information is provided, it is not meant as
comprehensive router configuration instructions. For detailed software configuration
information, refer to the Cisco IOS configuration guide and command reference
publications. These publications are available on the documentation CD that came with
your router or you can order printed copies. Refer to the “Ordering Documentation” section
in the “Overview of the Router” chapter for ordering information.
This publication describes a variety of router models that are similar in functionality, but
differ in the number of interfaces supported. Some information provided may not apply to
your particular router model.

Overview of the Router
Table 1-1 lists the router models discussed in this publication and provides a summary of
the interfaces supported on each model. These router models are similar in functionality,
but differ in the number of interfaces supported.
1. AUI = attachment unit interface.
2. ISDN = Integrated Services Digital Network.
3. BRI = Basic Rate Interface.
4. A CPA2515 model is not available.

1-2 Router Installation and Configuration Guide
Hardware Features
Note Throughout the remainder of the publication, one model number will be used in text
references. For example, references to the model 2501 router will apply to both the
Cisco 2501 and CPA2501 routers.
Hardware Features
In addition to the interfaces listed in Table 1-1, the routers include the following hardware
features:
•Dynamic random-access memory (DRAM) for main memory and shared memory
•Nonvolatile random-access memory (NVRAM) for storing configuration information
•Flash memory for running the Cisco IOS software
•EIA/TIA-232 console port for local system access using a console terminal
•EIA/TIA-232 auxiliary port for remote system access using a modem
Note EIA/TIA-232 and EIA/TIA-449 were known as recommended standards RS-232
and RS-449 before their acceptance as standards by the Electronic Industries Association
(EIA) and Telecommunications Industry Association (TIA).
