Release Notes for Cisco IOS Release 11.2(11) Software Feature Packs for Cisco 2500 Series Routers 19

Installing the Router Software Using a TFTP Server Application

First obtain a TFTP application or a remote copy protocol (rcp) application to set up your computer

as a TFTP server or an rcp server. Use the RSL or the TFTP server included on the feature pack

CD-ROM to install the router software only 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 same procedure, and substitute rcp for TFTP in the

instructions. Use 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 that includes a checkbox beside the word Server. To conﬁgure the local

PC as a server, click this 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.

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 also applies if you are using rcp instead of

TFTP.

Caution Make sure your PC is set up to communicate with the 10BaseT Ethernet port on the

router.
