This document describes how to upgrade portware for Cisco 3600 series digital modem network modules.
Portware is modem firmware (also called microcode) that is downloaded to the modems at startup. A version of portware is always bundled with the Cisco IOS image. A separate portware file can be stored in Flash memory to override this portware with one that contains newer features. If the router finds more than one version of portware at startup, it automatically loads the latest version.
Portware releases 2.5.1.0 and above provide support for 56 kbps transmission (V.90 and Rockwell K56Flex standards), dial-out, and fax-out. You can upgrade to this and later releases in any of the following ways:
To find out what portware release you have now, enter the show modem version command at the EXEC prompt, Router> or Router#.
Use this document with your router installation and configuration guide, the Network Module Hardware Installation Guide, the Software Configuration Guide, document for your router, and the Cisco IOS configuration guides and command references.
Cisco documentation and additional literature are available in a CD-ROM package, which ships with your product. The Documentation CD-ROM, a member of the Cisco Connection Family, is updated monthly. Therefore, it might be more current than printed documentation. To order additional copies of the Documentation CD-ROM, contact your local sales representative or call customer service. The CD-ROM package is available as a single package or as an annual subscription. You can also access Cisco documentation on the World Wide Web at http://www.cisco.com, http://www-china.cisco.com, or http://www-europe.cisco.com.
If you are reading Cisco product documentation on the World Wide Web, you can submit comments electronically. Click Feedback in the toolbar and select Documentation. After you complete the form, click Submit to send it to Cisco. We appreciate your comments.
If you have questions or need help, refer to the "Cisco Connection Online" section for further information.

New portware releases are available without charge at the following URL:

After downloading the portware file, transfer it to a TFTP, rcp, or MOP server on your network.
You can copy your downloaded portware from a network server into the same router Flash partition that holds the Cisco IOS image, or into a different partition.
If you use the same partition:
If you use a different partition, you avoid these problems, but:
To show information about system Flash partitions, including filenames and available space, enter the show flash: command from EXEC mode. To show information about Flash memory card partitions, enter the show slot0: or show slot1: command. Check the size of the release you are downloading to make sure you have enough Flash memory.
If you want to partition Flash memory, enter the following command in global configuration mode:
Router(config)# partition device: [number-of-partitions][partition-size]
where device: is flash: for system Flash, and slot0: or slot1: for the two PC Card slots. This command succeeds only if the system has at least two banks of Flash memory and the partitioning does not cause an existing file to be split across the partitions.
The number of partitions that you can create equals the number of banks in the Flash memory device. Enter the show device: all EXEC command to view the number of banks.
The number of partition size entries must equal the number of specified partitions. For example, partition slot0: 2 8 8 configures two partitions, each 8 MB in size. If the partition size is not specified, partitions of equal size are created.
If you plan to copy the new portware file to the same partition that holds your Cisco IOS image, we strongly recommend first backing up the image to a TFTP or rcp network server.
To back up the Cisco IOS image, enter the copy command:
Router# copy device:[partition-number:][filename] tftp | rcp
To stop the copy process, press Ctrl-^.
The following example copies the file your-ios from partition 4 of system Flash memory to the TFTP server at 172.23.1.129. Because all required information is specified in the command line, the software does not display Flash memory contents. The file is saved with the name c3640-j-mz in the dirt/images directory relative to the directory of the remote username.
Router# copy flash:4:your-ios tftp Address or name of remote host [172.23.1.129]? Destination file name [your-ios]? dirt/images/c3640-j-mz Verifying checksum for 'your-ios' (file # 2)... OK Copy 'your-ios' from Flash to server as 'dirt/images/c3640-j-mz'? [yes/no] yes !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Upload to server done Flash device copy took 00:00:20 [hh:mm:ss]
An exclamation point (!) indicates that the copy process is taking place. Each exclamation point (!) indicates that ten packets have been transferred successfully.
For more information about the copy command, see the "Loading and Maintaining System Images and Microcode" chapter in the Configuration Fundamentals Configuration Guide for your Cisco IOS release.
To copy the new portware from a TFTP, rcp, or MOP network server to the router, follow this procedure:
Step 1 Enter one of the following EXEC commands to verify that you have room in Flash memory for the portware file:
Router# show flash: Router# show slot0: Router# show slot1:
Step 2 Copy the portware file from the server:
Router# copy tftp | rcp | mop device:[partition-number:][filename]
 | Caution If you are copying portware to the partition that contains your Cisco IOS image, be sure to answer no when asked "Erase flash device before writing?" Otherwise you will erase the Cisco IOS image. |
Step 3 Verify that the portware file has been successfully copied to Flash memory, and that your Cisco IOS image is still in Flash memory, by entering the show device: command from Step 1. If the IOS image is no longer in Flash memory, restore it from backup using the copy command before rebooting the router.
Step 4 Reboot the router by entering the reload command:
Router# reload
Step 5 It may take several minutes for the router to reboot. When the Router> prompt appears, enter the show modem version command to verify that the new portware release has been downloaded to the modems:
Router> show modem version
The following example copies the file c3600-mica-portware.2.5.1.0.bin on the TFTP server at 172.23.1.129 to the first partition of internal Flash memory.
Router# copy tftp flash:1:c3600-mica-portware.2.5.1.0.bin System flash directory, partition 1: File Length Name/status 1 1711088 current-ios [1711152 bytes used, 2483152 available, 4194304 total] Address or name of remote host [172.23.1.129]? Source file name [c3600-mica-portware.2.5.1.0.bin]? Accessing file 'c3600-mica-portware.2.5.1.0.bin' on 172.23.1.129... Loading c3600-mica-portware.2.5.1.0.bin from 172.23.1.129 (via Ethernet1/0): ! [OK] Erase flash device before writing? [confirm] no
If you do not have access to a network server, you can copy the portware from a local or remote computer using the XMODEM or YMODEM protocol:
Router# copy xmodem | ymodem device:[partition-number:][filename]
For further information about copying files using XMODEM or YMODEM, see the "Loading and Maintaining System Images and Microcode" chapter in the Configuration Fundamentals Configuration Guide for your Cisco IOS release.
If you purchased a PC Card containing the new portware release (part number MEM56K-3600=), follow this procedure to install it:
Step 1 Insert the connector end of the card, label side up, into either of the PCMCIA slots on the front of the router until it is firmly seated. (See Figure 1.) Note that part of the card remains outside the slot.
Step 2 Reboot the router by entering the reload command:
Router# reload
Step 3 It may take several minutes for the router to reboot. When the Router> prompt appears, enter the show modem version command to verify that the new portware release has been downloaded to the modems:
Router> show modem version
