How to Use These Release Notes
How to Use These Release Notes
Use Table 1, “Cisco 2600 Series Default Memory and Upgrade Options,” to find the factory-default
memory and available upgrades for your router.
Use Table 3, “Feature Pack Product Numbers,” to identify the software image to load.
Use Table 4, “Cisco 2600 Series Feature Pack Image Filenames and Memory Requirements,” to find
the memory required for this image.
Use the tables in the “Features by Feature Set” section on page 12 to identify the features supported
in a feature set image.
What Is a Feature Pack?
A feature pack contains the following items:
•CD-ROM with the following software:
—Cisco IOS feature set software images, which might include bundled modem firmware
—Router Software Loader (RSL) program (a Windows 95 application)
—Trivial File Transfer Protocol (TFTP) server application (for Windows 95 only)
•Getting Started with the Router Software Loader CD booklet
•Release notes (this document)
•Software license for using Cisco software in object code form on a single access server or router
•Documentation CD-ROM that contains all Cisco documentation
The heart of a feature pack is the CD-ROM that contains software images and the RSL, which is a
Windows 95 application that loads an image onto a router or access server. Each feature pack
CD-ROM contains at least one Cisco IOS feature set. The CD booklet Getting Started with the
Router Software Loader explains how to use the RSL to install the router image. If you cannot use
the RSL to load images, you can follow the instructions in the “Alternatives to RSL” section on
page 18.
Before running the RSL, read the “Installing Software Images Using RSL” section on page 17. If
you are loading software on a preconfigured router, you should save the router configuration file on
your PC before beginning the image download process, as described in Getting Started with the
Router Software Loader.

Release Notes for Cisco IOS Release 12.0(7)XK1 Feature Packs for Cisco 2600 Series Routers 17
Installation Notes
Installation Notes
This section describes the following topics:
•Installing Software Images Using RSL, page 17
•Alternatives to RSL, page 18
Installing Software Images Using RSL
This section describes some solutions to problems you might encounter when installing software
images using the RSL. These solutions are additions to the RSL online help.
Recovering From a Connection Error
This installation tip provides a possible recovery solution if you are unable to connect to your access
server or router. You can skip this section unless you are experiencing a connection error.
In some cases, you might receive the following error message while connecting to the target access
server:
"Failed to configure the router to enable the Cisco IOS software image and
configuration file upload and download operations. You may want to check the router to
make sure that the selected interface exists."
If you encounter this message, especially if one of the following situations applies, try increasing the
Short Timeout value higher than 25 seconds in the Options dialog box:
•You are connecting to an access server that has a large configuration file.
•You are connecting to a Cisco AS5200 access server. A Cisco AS5200 requires up to 45 seconds
to write a configuration to nonvolatile random-access memory (NVRAM), due to the amount of
interfaces that must be checked during this process. Increase the Short Timeout value to
60 seconds.
Note Increasing the Short Timeout value might increase the time it takes for RSL to connect to the
target access server.
Restoring the Startup Configuration
In some cases, the RSL is unable to restore the startup configuration. If this happens, take the
following steps:
Step 1 Ensure that all cables are properly attached to both the router and the PC.
Step 2 Restart the RSL, and connect by using the Preconfigured router option.
Step 3 When asked if you want to overwrite the existing startup configuration file, choose no.
Step 4 When asked if you want to continue, choose yes.
Step 5 When the router is connected, select Download Router Configuration in the
Router Software Loader dialog box.
Step 6 Select the appropriate file, and click the radio button beside Copy configuration to the
router nonvolatile memory.
Theroutershould nowcontain the startup configuration it had before the initial RSL connection. You
can now exit the RSL.

18 Release Notes for Cisco IOS Release 12.0(7)XK1 Feature Packs for Cisco 2600 Series Routers
Installation Notes
Note In the previous situation, the router configuration register (config-register 0xnnnn) is not
restored.
Note If you press Ctrl-Alt-Delete to terminate the RSL, the router configuration and configuration
register are not restored. However, in this case, the configuration file is not deleted from the PC, so
you can restore it using the previous steps, beginning with Step 2.
Installation Tips The following information about RSL operations can help you with the installation process:
•If you have added any static entries to the PC Address Resolution Protocol (ARP) table, one or
more of them might be deleted by the RSL. You need to manually re-enter any deleted entries in
the PC ARP table.
•If the router’s running configuration at connection time is not the same as its startup
configuration, the exact configuration is not restored. Any changes that you have made since the
last time a copy running-config startup-config or write memory command was entered are
lost.
•The RSL restores the router’s startup configuration, but some running configuration commands
are not restored. To restore the exact running configuration, reboot the router. The following
interface configuration commands are not restored to the running configuration: no shutdown,
no ringspeed, and media-type aui.
Alternatives to RSL
RSL is designed to work with a PC running Microsoft Windows 95 and is the recommended method
for downloading software to the router. The booklet included with the CD-ROM explains how to
perform this simple install process; however, two alternatives are available for installing router
software:
•Using the console or auxiliary port
•Using a TFTP server application
Installing the Router Software Using the Console or Auxiliary Port
This section explains how to use the copy xmodem flash command to install the router software
from the CD-ROM onto the router.
Note The transfer takes place only on the port at which you enter the command. If you download
via the console, all console output is discarded for the duration of the transfer. You can only
download files to the router; you cannot copy files from the router. Cisco recommends using the
auxiliary port for this type of software download. The auxiliary port has hardware flow control and
full modem control. In addition, the transfer does not occupy the system console so it is free for other
uses.

Release Notes for Cisco IOS Release 12.0(7)XK1 Feature Packs for Cisco 2600 Series Routers 19
Alternatives to RSL
The following example shows how to use the copy xmodem flash command on a Cisco 2600 series
router.
Router# copy xmodem flash
**** WARNING ****
x/ymodem is a slow transfer protocol limited to the current speed
settings of the auxiliary/console ports. The use of the auxiliary
port for this download is strongly recommended.
During the course of the download no exec input/output will be
available.

Installing the Router Software Using a TFTP Server Application
Use this TFTP server application method as an alternative to using the RSL to install the router
software from the CD-ROM. You can perform this procedure using a PC (running Microsoft
Windows 95 or Microsoft Windows 3.1), a Macintosh, or a UNIX system. You can use either the
copy tftp flash or copy rcp flash command to download the router software to the router.
First, obtain a TFTP application or a remote copy protocol (rcp) application to set up your computer
as a TFTP server or a rcp server. Only use the RSL or the TFTP server included on the feature pack
CD-ROM to install the router software if you are using a PC running Windows 95. For other
operating systems, a number of TFTP or rcp applications are available from independent software
vendors or available as shareware from public sources on the World Wide Web.

20 Release Notes for Cisco IOS Release 12.0(7)XK1 Feature Packs for Cisco 2600 Series Routers
Installation Notes
Note To use an rcp application, follow the procedure below, substituting “rcp” for “TFTP”and
using the copy rcp flash command instead of the copy tftp flash command.
Step 1 Install any TFTP server application on the PC. (A PC application is included on the
feature pack CD-ROM for Microsoft Windows 95 only.)
Step 2 Launchthe TFTP serverapplication on the PC, usually by double-clickingtheapplication
icon or its .exe filename.
Step 3 Set up the PC as a TFTP server by using the TFTP server application setup or
configuration facility.
Most TFTP server applications include a setup facility that allows you to specify the PC
as a server. For example, from the TFTP menu of one application, you can select Settings
to display a panel, and configure the local PC as a server by selecting the Server
checkbox.
The TFTP server also allows the selection of a “root” directory. You must select the
directory in which the Cisco IOS files reside (for example, d:\cpswinst\images).
Step 4 Establish a console session from your local PC (which is now configured as a TFTP
server) to the Cisco router by using one of these methods:
•Connect the PC com port to the router console port.
This is the recommended method.When you reload the router with the new image in
Step 25, you remain connected to the router. (If you use Telnet, you lose connection
to the router.)
•Establish a Telnet session from the PC to the router.
Step 5 Connect your PC Ethernet port to the corresponding router LAN port. Use the 10BaseT
crossover cable to connect to an Ethernet port. Use straight-through cables if you are
connecting via a 10BaseT hub or a 100BaseT hub.
Note We recommend that you back up the router configuration before upgrading the
router software.
Step 6 Enter the following commands to set the configuration register to 0x2101 and reload to
the bootstrap image:
Router# config terminal
Router(config)# config-reg 0x2101
Router(config)# end
Router# reload
Caution Make sure you set up your local PC as a TFTP server. If you overlook this step, you
cannot perform the copy procedure. This reminder applies to both TFTP and rcp.
Caution Make sure your PC is set up to communicate with the 10BaseT Ethernet port on the
router.
