Cisco 3600 Series and Cisco 3700 Series
Modem Portware Upgrade Configuration Note

Product Numbers: NM-6DM=, NM-12DM=, NM-18DM=, NM-24DM=, NM-30DM=, MEM56K-3600=

This document describes how to upgrade portware for Cisco 3600 series and Cisco 3700 series digital modem network modules.

Note The digital modems described in this document are MICA (multiservice IOS channel aggregation) modems.

Portware is modem firmware (DSP and control processor code) that is downloaded to the modems at startup. A version of portware is always bundled with the Cisco IOS image. A separate, nonbundled, portware file, such as a newer version, can be stored in Flash memory. When a router starts up or reboots, it searches the Cisco IOS image and Flash memory for the newest version of portware, and it loads the newest portware into the modem network modules.

In Cisco IOS release 12.2(3.6)T and later releases, a new modem firmware command is available. The modem firmware command allows you to load a specified nonbundled portware file from Flash memory into a modem. This enables the following actions:

•Loading new portware without rebooting the router.

•Loading an older portware version than the version in the Cisco IOS image.

•Loading different portware versions into different network module slots.

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:

•Download the new portware file from Cisco Connection Online (CCO), and copy it to your router's internal (system) Flash memory.

•Download the new portware file from CCO, and copy it to a Flash memory PC Card.

•Install a PC card containing the new portware version. This method is the fastest and most convenient, but it requires you to purchase the PC card from Cisco Systems (part number MEM56K-3600=).

Note Later releases of Cisco IOS software may contain later versions of bundled portware.

To find out what portware release you have now, enter the show modem version command at the user EXEC or privileged EXEC prompt, Router> or Router#.

Use this document with your router installation and configuration guide, the Cisco Network Modules Hardware Installation Guide, the Software Configuration Guide for Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Routers, and the Cisco IOS configuration guides and command references.

This document contains the following sections:

Downloading the New Portware Release

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

http://www.cisco.com/public/sw-center/sw-access.shtml

After downloading the portware file, transfer it to a TFTP, rcp, or FTP server on your network.

Copying Portware to Flash Memory

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:

•You might not have enough Flash storage for the portware.

•You might inadvertently erase the Cisco IOS image. We strongly recommend that you back up the image before upgrading the portware.

•If you later upgrade to a new Cisco IOS release, you might overwrite your preferred portware release and have to copy it again.

If you use a different partition, you avoid these problems, but:

•You have to use an entire partition for the portware. System Flash memory can have either 4- or 8-MB partitions. A Flash card can have 1-MB partitions. Portware occupies much less than 1 MB.

To show information about system Flash partitions, including filenames and available space, enter the show flash:. 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 that you have enough Flash memory.

Partitioning Flash

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.

Backing Up the Current Cisco IOS Image

If you plan to copy the new portware file to the same partition that holds your Cisco IOS image, Cisco strongly recommends that you first back up the image to a TFTP or rcp network server.

Note The rcp transport mechanism provides faster performance and more reliable delivery of data than TFTP. In some implementations of TFTP, you must first create a "dummy" file on the TFTP server and give it read, write, and execute permissions before copying a file over it.

To back up the Cisco IOS image, enter the copy command: 

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

For more information about the copy command, see the "Loading and Maintaining System Images and Microcode" chapter in the Cisco IOS Configuration Fundamentals Configuration Guide, Release 12.2.

Copying Portware to Flash Using TFTP, rcp, or FTP

To copy the new portware from a TFTP, rcp, or FTP 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: 

copy {tftp | rcp | ftp} 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.

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

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 appropriate 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 Proceed to the "Loading Portware into MICA Modems" section to update the modems with the new portware.

Copying Portware to Flash Using XMODEM or YMODEM

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.

Step 1 Enter one of the following 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 to Flash memory: 

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 Cisco IOS Configuration Fundamentals Configuration Guide, Release 12.2.

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 appropriate show device: command from Step 1. If the Cisco IOS image is no longer in Flash memory, restore it from backup using the copy command before rebooting the router.

Step 4 Proceed to the "Loading Portware into MICA Modems" section to update the modems with the new portware.

Installing Portware from a PC Card

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 Proceed to the "Loading Portware into MICA Modems" section to update the modems with the new portware.

Figure 1 Installing a PC Card with Portware

Loading Portware into MICA Modems

To load portware that is bundled with the Cisco IOS software image, you must reboot the router; however, if a newer version of portware is present in Flash memory, the Cisco IOS software finds and loads the newer version into the modems. For rebooting instructions, see the "Loading by Rebooting the Router" section.

To load an older version from Flash memory, or to load portware from Flash memory without rebooting the router, use the modem firmware command. For instructions on using the modem firmware command, see the "Loading with the modem firmware Command" section.

Note To load an older version of portware that is bundled in the Cisco IOS, you must delete any newer versions from Flash memory and then reboot the router.

Loading by Rebooting the Router

To load the newest available version of portware into all installed modems, or to load the portware that is bundled with the Cisco IOS software image, reboot the router.

Step 1 Reboot the router by entering the reload command: 

Router# reload

Step 2 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

Loading with the modem firmware Command

To load a specified version of portware into specified modems, or to load any portware that is resident in Flash memory and is older than the portware that is bundled with the Cisco IOS software image, use the modem firmware command.

Step 1 Download the portware using the modem firmware command in global configuration mode: 

Router(config)# modem firmware slot slot-number location ifsfilename

•The slot-number argument specifies the chassis slot that contains the network module with the MICA modem.

•The ifsfilename argument specifies the Cisco IOS file system (IFS) filename of the portware to be loaded into the modem.

Step 2 Exit from global configuration mode: 

Router(config)# exit

Step 3 Enter the show modem version command to verify that the new portware release has been downloaded to the modem: 

Router# show modem version

Note It may take a minute or two for the new version to appear.

Example: 

router(config)# modem firmware slot 1 location flash:pw2730.ios


 This command will disconnect any active calls.

 Modem Slot 1 :Started firmware download.

 Modem Slot 1: Completed firmware download


router(config)# exit


router# show modem version
