Upgrading Modem Code from the Cisco CCO TFTP Server Note To download modem code from CCO to a PC and then upgrade the modem code to an access server connected to your PC via an Ethernet hub, you need to set up a TFTP application on your PC, establish a HyperTerminal session, and make sure your PC and access server are correctly connected and talking before downloading the modem code from CCO. All these procedures are described in "Upgrading Modem Code from Diskettes," later in this appendix. Using an Internet Browser Step 1 Launch an Internet browser. Step 2 Bring up Cisco's Software Center home page at following URL (this is subject to change without notice): http://www.cisco.com/kobayashi/sw-center/ Step 3 Click Access Products (under Cisco Software Products) to open the Access Products window. Step 4 Click Cisco AS5300 Series Software. Step 5 Click the modem code you want and download it to your workstation or PC. For example, to download modem code for the Microcom modems, click Download Microcom V.34 Modem Firmware or Download Microcom 56K Modem Firmware under the respective sections. To download modem code for MICA modems, click Download Modem Portware Images. Step 6 Click the modem code file you want to download, and then follow the remaining download instructions. If you are downloading the modem code file to a PC, make sure you download it to the c:\tftpboot directory; otherwise, the download process will not work. Step 7 When the modem code is downloaded to your workstation, transfer the file to a TFTP server in your LAN using a terminal emulation software application. Step 8 When the modem code is downloaded to your workstation, transfer the file to a TFTP server somewhere in your LAN using a terminal emulation software application. Using an FTP Application Note The directory path leading to the modem code files on cco.cisco.com is subject to change without notice. If you cannot access the files using an FTP application, try the Cisco Systems URL http://www.cisco.com/kobayashi/sw-center/. Step 1 Log in to the Cisco CCO FTP server, called cco.cisco.com: terminal> ftp cco.cisco.com Connected to cio-sys.cisco.com. 220- 220- Cisco Connection Online | | Cisco Systems, Inc. 220- Email: [email protected] ||| ||| 170 West Tasman Drive 220- Phone: +1.800.553.2447 San Jose, CA 95134 220- 220- NOTE: As of February 1,1997 ftp.cisco.com will now point to this 220- service. Please be advised. To use the former ftp.cisco.com after 220- February 1, connect to ftpeng.cisco.com 220- Managing Modems A-15

Upgrading Modem Code from the Cisco CCO TFTP Server

Managing Modems

A-15

Note

To download modem code from CCO to a PC and then upgrade the modem code to an access

server connected to your PC via an Ethernet hub, you need to set up a TFTP application on your PC,

establish a HyperTerminal session, and make sure your PC and access server are correctly connected
