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 2, "Interfaces Supported on Cisco 2600 Series Routers," to find the LAN and WAN interfaces available for routers in this series.

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 Table 5, "Features by Feature Set for Cisco 2600 Series," to identify the features supported in a feature set image.

What Is a Feature Pack?

A feature pack contains the following items:

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, follow the instructions in the "Alternatives to RSL" section.

Before running the RSL, read the "Installing Software Images Using RSL" section. 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.

Memory Options

Cisco 2600 series routers are shipped with 8 MB of system Flash memory and 32 MB of DRAM (effective March 1, 2000). Cisco 2610, Cisco 2611, Cisco 2612, Cisco 2613, Cisco 2620, and Cisco 2621 routers support a maximum of 16 MB of Flash memory and 64 MB of DRAM. Cisco 2650 and Cisco 2651 routers support a maximum of 32 MB of Flash memory and 128 MB of DRAM.

Note   Cisco 2650 and Cisco 2651 routers use synchronous DRAM (SDRAM) only. Other Cisco 2600 series routers use extended data output (EDO) DRAM only. These two types of DRAM must be used in the proper routers and are not interchangeable.
Note   The 32-MB Flash SIMM module is designed for Cisco 2650 and 2651 routers only, and cannot be used in other Cisco 2600 series routers.

Table 1 describes default memory and upgrade options for Cisco 2600 series routers.

Note   Part numbers without an equals sign (=) identify products installed in a router at the factory. Part numbers followed by an equals sign identify products sold as spares (separately).

Installation Notes

This section describes the following topics:

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:

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.

The router should now contain the startup configuration it had before the initial RSL connection. You can now exit the RSL.

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:

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:

Installing the Router Software Using the Console or Auxiliary Port

This section explains how to use the copy xmodem flash command to install router software from the CD-ROM.

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.

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.

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   Launch the TFTP server application on the PC, usually by double-clicking the application 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).

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.

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:

  This is the recommended method.When you reload the router with the new image in Step 16, you remain connected to the router. (If you use Telnet, you lose connection to the router.)
Caution Make sure your PC is set up to communicate with the 10BaseT Ethernet port on 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

Step 7   When asked whether the system configuration has been modified, enter yes:

# System configuration has been modified. Save? yes

Step 8   If the password prompt appears, enter the password.

Password: password

Step 9   At the router prompt, enter enable and then the password:

Router(boot)> enable
Password: password

Step 10   At the router prompt, enter the following command to copy the new software image from the PC CD-ROM drive to the router:

Router(boot)(config)# copy tftp flash

In the next series of steps, you download the Cisco IOS Release 12.1(3)T1 images that you want installed on your router.

Step 11   When prompted, enter the IP address of your PC, as in the following example:

Address or name of remote host [255.255.255.255]? 172.11.1.1

This is the IP address of your local PC, not that of the router.

Step 12   When prompted, enter the filename of the Cisco IOS Release 12.1(3)T1 image to be copied to the router, as in the following example:

Source file name? aaa1581.bin

This example specifies the DOS image name of the IP feature set for Cisco 2600 series routers (as shown in Table 4 in the "Feature Pack Overview" section).

Step 13   In response to the prompt, enter the destination UNIX image filename, and press Enter.

This is the name of the image file on the router, not the full pathname of the image on the CD-ROM attached to the PC. Refer to Table 4 in the "Feature Pack Overview" section for the UNIX image filename.

Destination file name [aaa01308.bin]? c2600-is-mz.121-3a.T1

During the transfer process, the software displays messages indicating that it has accessed the file you have specified and is loading it.

Step 14   Enter yes in response to the prompt asking if you want to erase the existing image copy resident in the router Flash memory before copying the new one.

Erase flash device before writing? [confirm] yes

The entire copying process takes several minutes and differs from network to network.

The exclamation point (!) indicates that the copy process is taking place. Each exclamation point (!) indicates that ten packets have been transferred successfully. A checksum verification of the image occurs after the image is written to Flash memory.

Step 15   Enter the following commands to reset the configuration register to 0x2102.

Router(boot)(config)# config terminal
Router(boot)(config)# config-reg 0x2102
Router(boot)(config)# end

Step 16   Enter the reload command to reload the router:

Router# reload

After reload is complete, the router should be running the required Cisco IOS image. Use the show version command to verify.
