model.)
•One fixed WAN port (except for the Cisco 1605). (Refer to Table 1-1 for more
information about the WAN connections supported by each model.)
•One slot for a WAN interface card, for flexibility in choosing WAN connections that the
router supports. (Refer to the section “WAN Interface Cards” later in this chapter for
more information about WAN interface cards.)
•Flash memory PC card (PCMCIA-compatible), which can be preconfigured by a
network administrator and installed in the router at a remote site.
•Console port, which supports router management using a terminal or a PC with terminal
emulation software.
•Router management over the network using Simple Network Management Protocol
(SNMP).
•AutoInstall for downloading configuration files automatically over a WAN connection.

WAN Interface Cards
On the Cisco 1601 through Cisco 1604, you can use the WAN interface card connection as
a secondary WAN connection, which can be used if the router on-board WAN connection
fails. On the Cisco 1605, you can choose the type of WAN connection that you want for
your network.
For more information about the cards, including function, installation, and configuration,
refer to the Cisco WAN Interface Cards Hardware Installation Guide document that comes

Overview of the Router 1-7
Router Memory
Router Memory
The Cisco 1600 series routers are either of run-from-flash (RFF) or run-from-RAM (RFR)
models. Router model names with an Rare RFR routers; all other models are RFF. In this
document, model names without an Rrefer to both RFF and RFR models, except where
noted. This section describes the two memory architectures used in the Cisco 1600 series
routers.
Run-From-Flash Architecture
With RFF, the microprocessor uses the uncompressed Cisco IOS software image that is
stored in Flash memory. The software image runs directly from Flash memory. RAM stores
working data such as Cisco IOS data structures, network routing tables, and packets to be
transmitted to and received from network interfaces.
The running software image cannot be used to download new software to Flash memory
because it would attempt to overwrite itself. (However, when you are using Dual Flash
Bank memory, you can download the new software image into a different Flash memory
partition.)
To download a new software image without using Dual Flash Bank memory, a boot-helper
image (called XBOOT) has been added to the ROM on the RFF models. The boot-helper
image is a small subset of Cisco IOS software that supports only a subset of the interfaces
and the WAN protocols. RFF ROM supports the following WAN interfaces. (These are all
onboard interfaces, not WAN-interface-card interfaces.)
•Serial (synchronous and asynchronous) (Cisco 1601)
•DSU/CSU (Cisco 1602)
•ISDN S/T (Cisco 1603)
•ISDN U (Cisco 1604 and Cisco 1604 R)
When upgrading the Cisco IOS software in Flash memory, you must boot the router from
the ROM image. The Flash memory can be overwritten because the Cisco IOS software
that is stored in Flash memory is not being used to run the router.

Router Memory
Cisco 1600 Series Router Hardware Installation Guide
1-8
Run-From-RAM Architecture
With RFR, the Cisco IOS image is stored in Flash memory (usually in compressed form),
butisloaded into RAM before being used to operatethe router. The running software image
then resides in RAM, so a new software image can be downloaded and copied over the
software image stored in Flash memory.
In RFR routers, only a minimal boot-helper image is stored in the ROM for disaster
recovery. Initial loading of a software image into Flash memory is done over the console
port or the local Ethernet.
Because the Cisco IOS image is stored in compressed form in Flash memory and then
decompressed when loaded into RAM, the standard configuration for the RFR models
contains less Flash memory but more DRAM than the RFF models.
Table 1-3 is a summary comparison of these two memory architectures.

Installing the Router
This chapter contains hardware installation procedures for Cisco 1600 series routers and
includes the following sections:
•Before Installing
•Connecting Power and Turning On the Router
•Connecting the Router to the LAN
•Connecting the Router to the WAN
•Connecting the Console Port
Note You might want to perform some optional installation steps that are not explained in
this chapter, including wall-mounting the router, installing the Flash PC card, connecting
an ISDN telephone, or installing a WAN interface card. These procedures are explained in
the “Optional Installations” chapter later in this document.
Before Installing
Cisco 1600 series routers are shipped to you ready for desktop mounting. Before making
the power and network connections, simply set the router on a desktop, shelf, or other flat
surface. Be sure to read the safety information in the Regulatory Compliance and Safety
Information for Cisco 1600 and Cisco 1700 Routers that came with your router.
Warning Read the installation instructions before you connect the system to its
power source.

Connecting Power and Turning On the Router
Cisco 1600 Series Router Hardware Installation Guide
2-2
Caution Do not place anything on top of the router that weighs more than
10 pounds (4.5 kg). Excessive weight on top of the router could damage the
chassis.
Warning Do not work on the system or connect or disconnect cables during
periods of lightning activity.
Connecting Power and Turning On the Router
If you turn on the router before making network connections, you can verify your
installation by checking the appropriate LEDs during the installation process.
Warning The power supply is designed to work with TN power systems.
Warning This product relies on the building’s installation for short-circuit
(overcurrent) protection. Ensure that a fuse or circuit breaker no larger than
120 VAC,15A U.S.(240 VAC, 10A international) is used on the phase conductors
(all current-carrying conductors).
Warning This equipment is intended to be grounded. Ensure that the host is
connected to earth ground during normal use.
Follow these steps to connect the router to power and turn it on:
Step 1 Connect the DC power cable (included with the router) from the power supply
to the DC power input on the rear panel of the router.
Step 2 Connect the male end of the power cable to the power outlet.
Step 3 Connect the female end of the cable to the male receptacle on the power supply.
Step 4 On the rear panel of the router, turn ON the power by setting the switch labeled
| / O to the | position.
Step 5 Slip the wire clip over the power cord to ensure that the power cord remains
attached to the router, as shown in Figure 2-1.
