Safety with Electricity

Follow these guidelines when working on equipment powered by electricity:


Read the installation instructions before you connect the system to its power source.

Ultimate disposal of this product should be handled according to all national laws and regulations.

Only trained and qualified personnel should be allowed to install or replace this equipment.

To ensure your safety and the safety of others, be sure the power is OFF and the power cord is unplugged before working on the router.
  • Disconnect all power before doing the following:
    • Installing or removing a chassis
    • Working near power supplies

Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.

Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages.

Do not work on the system or connect or disconnect cables during periods of lightning activity.

Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected.

This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.

Hazardous network voltages are present in WAN ports regardless of whether power to the router is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the router first.
  • Do not work alone if potentially hazardous conditions exist.
  • Never assume that power is disconnected from a circuit. Always check.
  • Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, and missing safety grounds.
  • If an electrical accident occurs, proceed as follows:
    • Use caution; do not become a victim yourself.
    • Turn OFF power to the system.
    • If possible, send another person to get medical aid. Otherwise, determine the condition of the victim and then call for help.
    • Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by touching the metal part of the chassis.


For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohm (Mohm).

Installation Overview

The use of 56K modems introduces new steps for installing and configuring modem code. With some Cisco IOS releases, you must first install the 56K modem code (modem firmware and DSP software). The following steps provide an overview of the installation process:

1. Verify that the Cisco AS5200 is running Cisco IOS Release 11.2(8)P or later. If necessary, upgrade your system software.

2. Install the module, as described in the section "Installing the 56K 12-Port Module."

3. If necessary, upgrade the modem code, as described in the sections "Downloading Modem Code for Releases Requiring Two Files" or "Downloading Modem Code for Releases Requiring a Single File."


Note      Depending on how often modem code images are downloading in to your boot Flash memory, the boot Flash memory in your Cisco AS5200 may not have the available space to accept the additional 56K images. If you experience this, refer to the section "Erase Boot Flash Memory and Restore the Boot Image,".


Installing the 56K 12-Port Module

You must install 56K modules in a carrier card or a dual E1/PRI card, which are not included with this kit. The carrier card, shown in Figure 2, is a wide, narrow card with two slots in which you can install up to two 56K modules (or other supported modules). Figure 3 shows the dual E1/PRI card, which has only one slot. You can install 56K modules with any combination of other supported modules.


Figure 2   Carrier Card



Figure 3   Dual E1/PRI Card


Required Tools

You will need the following tools:

  • ESD-preventive wrist strap
  • Medium-size flat-blade screwdriver (1/4 in. [0.625 cm])

Installation

Refer to Figure 4 and take these steps:

Step 1   Attach an ESD-preventive wrist strap.

Step 2   Power OFF the access server.


Unlike some other Cisco access servers, the modules are not hot-swappable (that is, you cannot remove or install them when the access server power is ON). Be sure to power OFF the access server before installing or removing modules. Failure to do so can damage the access server.

Step 3   Remove all interface cables from the back panel of the access server.

Step 4   Remove the blank cover or module installed in the carrier card or dual E1/PRI card.


Note If the carrier card or dual E1/PRI card is already installed in the access server, you can install 56K modules in the card without removing it from the chassis.


Step 5   Remove the 56K module from the ESD-preventive shipping material.

Step 6   Slide the 56K module into the carrier card or dual E1/PRI card slot until it is seated completely.

Step 7   Tighten the two captive screws on the 56K module to secure it to the carrier card or dual E1/PRI card.

If you have questions or need assistance, refer to the section "Cisco Connection Online" at the end of this document. Otherwise, proceed to one of these sections, "Downloading Modem Code for Releases Requiring Two Files" or "Downloading Modem Code for Releases Requiring a Single File."

Decisions about Downloading 56K Modem Code

The modem code download process depends on your Cisco IOS software release and your configuration. Select one of the following actions:

  • You must download two files (modem firmware and DSP software) if you are running the following releases:
    • Cisco IOS Release 11.2(8)P
    • Cisco IOS Release 11.2(9)P
    • Cisco IOS Release 11.3(1)T (future)
    • Cisco IOS Release 11.3(1) and later (future)

For instructions, see "Downloading Modem Code for Releases Requiring Two Files,".

  • Because default modem code is bundled with some versions of Cisco IOS software, you do not need to download any modem code if you are running the following releases:
    • Cisco IOS Release 11.2(10)P or later (future)
    • Cisco IOS Release 11.3(2)T or later (future)
  • You can decide to override the modem code automatically selected by Cisco IOS Release 11.2(10)P or later or Cisco IOS Release 11.3(2)T (future) or later. See "Downloading Modem Code for Releases Requiring a Single File,".

Downloading Modem Code for Releases Requiring Two Files

Access servers running Cisco IOS Release 11.2(8)P, 11.2(9)P, 11.3(1)T (future), or 11.3(1) (future) and later must contain two compatible files:

  • 56K modem firmware—Located in Flash memory on the 56K modems
  • DSP software—Located in boot Flash memory on the Cisco AS5200

First shipments of the 12-port module contained version 3.1.30 modem firmware. You must always download the compatible DSP software from the disk shipped with the module.

Table 1 describes the current firmware and software versions. In the middle column, note that the filenames are similar, which indicates that the files are compatible.

56K Modem Firmware and DSP Software

You must download the files identified in Table 1 to a TFTP server on your LAN, then copy the files to the access server's boot Flash memory.

Choose a method to download the files:

Download Method 1—Use an Internet Browser

Log in to Cisco's Software Center at the following URL to download both 56K files. You must log in as a Cisco registered user (nonregistered users must use the DSP software on the disk shipped with the module):

http://www.cisco.com/cgi-bin/tablebuild.pl/56K

Alternately, you can access Cisco at http://www.cisco.com, login, and take the following path to the files:

  • Service and Support
  • Software Center
  • Access Products
  • Cisco AS5200 Series Software
  • Download Microcom 56K Modem Firmware

After the files are downloaded to your desktop computer, you must transfer them to a TFTP server on your network using an FTP application.

Download Method 2—Use a Traditional FTP Application

Take the following steps to download the 56K files mentioned above from Cisco's FTP server using an FTP client application. The steps assume that you want to download both the modem firmware and the DSP software. (For initial installations, only the DSP software is required. These instructions are provided for future versions of modem firmware.)


Note      The directory path leading to the 56K images on cco.cisco.com is subject to change without notice. If you cannot access the files using an FTP application, use Download Method 1.



Step 1   Log in to Cisco System's CCO FTP server, which is called cco.cisco.com:

226 Transfer complete.

Step 5   Specify a binary image transfer:

ftp> binary
200 Type set to I.

Step 6   Copy the modem firmware and/or DSP software files from the server to your local environment with the get command. The filenames follow:

  • mcom-modem-fw-3.1.30-1.1.0.bin
  • mcom-modem-dsp-3.1.30-1.1.0.bin

Note      For initial installations, you will only need to copy the DSP software (mcom-modem-dsp-3.1.30-1.1.0.bin) because the modem firmware is installed on the module at the factory. When Cisco releases updated modem firmware in the future, use these instructions to download the files.


The following example downloads the DSP software file:

ftp> get mcom-modem-dsp-3.1.30-1.1.0.bin
PORT command successful.
Opening BINARY mode data connection for mcom-modem-dsp-3.1.30-1.1.0.bin (96708 bytes).

96708 bytes received in 0.30 seconds (3.2e+02 Kbytes/s)

The following example downloads the modem firmware file:

ftp> get mcom-modem-fw-3.1.30-1.1.0.bin
PORT command successful.
Opening BINARY mode data connection for mcom-modem-fw-3.1.30-1.1.0.bin (280208 bytes).
Transfer complete.
local: mcom-modem-fw-3.1.30-1.1.0.bin remote: mcom-modem-fw-3.1.30-1.1.0.bin
280208 bytes received in 0.63 seconds (4.4e+02 Kbytes/s)

Step 7   Quit your terminal session:

ftp> quit
Goodbye.

Step 8   If you have not already done so, you must now transfer these files to a local TFTP server that your Cisco AS5200 can access.


Note      If you loaded Cisco IOS software from a feature pack CD-ROM, note that the CD contains a TFTP server program for PCs using Windows 95. Run the server program from the directory where you installed the Router Software Loader (RSL) program. Remember to set the Root directory to the directory where the AS5200 56K files are located. RSL is available on the software feature pack CD and on CCO in the software library in the Access Products section.


Download Method 3—Use the Disk Shipped with the Module

If you do not have access to the Cisco Software Center or the Cisco FTP server and decide to use the software on the disk shipped with your module, you must first copy the file mcom-modem-dsp-3.1.30-1.1.0.bin to your tftp server, then download the software to the modem using the method described in the next section "Upgrade the 56K Modems to the Latest 56K Modem Firmware ."

Upgrade the 56K Modems to the Latest 56K Modem Firmware

The procedure for copying the 56K modem firmware from a local TFTP server to the 56K modem's Flash memory is described in this section. Note that the firmware shipped with your 56K 12-port module matches the DSP software on the disk. This step is unnecessary with the 56K modem firmware version 3.1.30. As revised modem code is available, you can use the procedures in this section to upgrade the 56K modes to the latest version.

Step 1—Create an Empty Boot Flash Memory Image File on Your UNIX TFTP Server

Before you back up your boot Flash image with the copy bootflash tftp command using a UNIX TFTP server, you must create an empty destination file on your local TFTP server:


Step 1   Log on to the Cisco AS5200 and find out the name of the boot image file in boot Flash memory with the show bootflash command:

router> enable
Password: letmein
router# show bootflash
Boot flash directory:
File Length Name/status
1 6465584 c5200-is-l.112-6.4
[6465648 bytes used, 1922960 available, 8388608 total]
8192K bytes of processor board Boot flash (Read/Write)
router#

Step 2   Go to your TFTP server and create an empty file using your boot image's filename, then change its permissions to be world writable:

henry-sun:/tftpboot> touch c5200-is-l.112-6.4
henry-sun:/tftpboot> chmod 666 c5200-is-l.112-6.4
henry-sun:/tftpboot> ls -l c5200-is-l.112-6.4
-rw-rw-rw- 1 henry cisco 6465584 Jul 14 15:25 c5200-is-l.112-6.4

The placeholder or destination file is now created and prepared for the backup copy operation. Proceed to the next section "Step 2Back Up the Boot Flash Image and Disable Modem Autoconfigure."

Step 2—Back Up the Boot Flash Image and Disable Modem Autoconfigure

Perform the following steps on the Cisco AS5200:


Step 1   Back up your boot Flash image to a local TFTP server on your network with the copy bootflash tftp command. This provides a recovery mechanism for you in case you accidentally erase or damage your boot Flash image in one of the later steps.

router# copy bootflash tftp

Step 2   Enter global configuration mode and disable the modem autoconfigure command on the TTY lines that correspond with the 56K modems. Ignore this step if this command is not enabled in your system configuration. In the following example, one 12-port 56K modem card is installed in slot 2:

router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)# line 13 24
router(config-line)# no modem autoconfigure
router(config-line)# exit
router(config)# exit
router#
%SYS-5-CONFIG_I: Configured from console by console

The boot image is now backed up and modem autoconfigure is disabled. Proceed to the next section "Step 3Upgrade to the Latest 56K Modem Firmware."

Step 3—Upgrade to the Latest 56K Modem Firmware

Perform the following steps:


Step 1   Log in to the Cisco AS5200 and copy the new modem firmware file from your TFTP server directly to the installed 56K modems using the copy tftp modem Privileged EXEC command:

router# copy tftp modem

Step 2   Specify the range of 56K modems that you want to upgrade. This example shows the range of modems to be 2/12 through 2/23:

Modem Numbers (<slot>/<port>[-<slot>/<port>] | group <number> | all)? 2/12-2/23

Step 3   Specify the name or address of the TFTP server holding the new modem firmware. Press the Return key to accept the default name or IP address enclosed in the brackets []. Also specify the source path/filename of the firmware.

Address or name of remote host [255.255.255.255]? tftp-server
Source file name? mcom-modem-fw-3.1.30-1.1.0.bin
Accessing file 'mcom-modem-fw-3.1.30-1.1.0.bin' on tftp-server...

The 56K modems are now upgraded to the latest version of modem firmware. Proceed to the next section "Copy the RAM-Based DSP Software ."

Copy the RAM-Based DSP Software

The procedure for copying the DSP software from to a local file server to the access server's boot Flash memory is described in this section:

These two steps are performed only once. Although the DSP software runs from RAM, the Cisco IOS software automatically copies the DSP code from boot Flash memory to the 56K modems each time the access server power cycles in the future. After you copy the DSP software filename into boot Flash memory for the first time, you should not have to perform these steps again.


Note      A list of download failure reasons and recommended actions is provided in Table 5.


Step 1—Copy the RAM-Based DSP Software to Boot Flash Memory


Step 1   Copy the DSP software file from your TFTP server to the access server's boot Flash memory using the copy tftp bootflash command. The Cisco IOS software prompts you with a sequence of questions such as name/address of the TFTP server and the DSP filename to be copied. Answer all of the questions accordingly.

router# copy tftp bootflash
Boot flash directory:
File Length Name/status
1 2348148 as5200-boot-l.111-7.AA
[2348212 bytes used, 6040396 available, 8388608 total]

Step 2   Specify the address or name of the server that currently holds the DSP software. You must also specify the source path/filename of the DSP software and the destination filename. The system software proposes a destination filename for you, which is enclosed in square brackets []. Press the Return key to accept the default destination name.

Address or name of remote host [255.255.255.255]? tftp-server
Source file name? mcom-modem-dsp-3.1.30-1.1.0.bin
Destination file name [mcom-modem-dsp-3.1.30-1.1.0.bin]?
Accessing file 'mcom-modem-dsp-3.1.30-1.1.0.bin' on tftp-server...
Loading mcom-modem-dsp-3.1.30-1.1.0.bin from 172.16.1.129 (via Ethernet0): ! [OK]

Step 3   When the system asks to confirm erasing the Flash memory device before copying the DSP file, enter no. You will now see a warning message appear that says the DSP file cannot be executed on the system (unlike a feature set or system image). Ignore this message.

Erase flash device before writing? [confirm] no
%Warning: File not a valid executable for this system

Step 4   Initiate the copy operation by entering y then pressing the Return key at the [confirm] prompt:

Copy file? [confirm] y

Step 5   Continue with the copy operation by entering yes and pressing the Return key:

Copy 'mcom-modem-dsp-3.1.30-1.1.0.bin' from server as 'mcom-modem-dsp-3.1.30-1.1.0.bin' into Flash WITHOUT erase? [yes/no] yes
Loading mcom-modem-dsp-3.1.30-1.1.0.bin from 172.16.1.129 (via Ethernet0): !!!!!!!!!!!!!!!!!!![OK - 96708/6040396 bytes]
Verifying checksum... OK (0x9B87) Flash device copy took 00:00:02 [hh:mm:ss]

Now the DSP software is in the access server's boot Flash memory. Proceed to the next section, "Step 2Copy the DSP Software Filename to the 56K Modems" for step-by-step instructions on how to transfer the DSP image to the 56K modems.

Step 2—Copy the DSP Software Filename to the 56K Modems


Step 1   Copy the DSP software filename to the 56K modems by entering the copy flash modem Privileged EXEC command. After you enter this command, specify the range of 56K modems that you want to target with the DSP software. In this example, only one 12-port 56K modem board is installed in the Cisco AS5200.

router# copy flash modem
Modem Numbers (<slot>/<port>[-<slot>/<port>] | group <number> | all)? 2/12-2/23

Step 2   Specify the filename of the DSP software and press the Return key. Note that the filename must be preceded by bootflash:, which is necessary to address the file that is stored in boot Flash memory.

Name of file to copy? bootflash:mcom-modem-dsp-3.1.30-1.1.0.bin
[OK - 96708/278528 bytes]
Downloading modem DSP file: bootflash:mcom-modem-dsp-3.1.30-1.1.0.bin
DSP Rev: 1.1(0)

Step 3   Proceed with the DSP download by entering y and pressing the Return key:

Proceed with DSP download? [n]: y
Downloading modem DSP file. Check current modem firmware version.
If firmware version is not the correct version to run with DSP image,
the correct firmware version must also be downloaded.

Note Now the 56K modems are equipped with the DSP software. The modems are configured to transmit at speeds up to 56 kbps. Each time the access server is power cycled, the system software automatically loads the 56K modems with the DSP software in boot Flash memory. If you erase the DSP software file from boot Flash memory, the 56K modems will revert to V.34 operation on the next power cycle.


Step 4   Verify that the DSP software copied to the 56K modems with the show modem version command. In this example, modems 2/12 through 2/23 are loaded with the new DSP software:

Downloading Modem Code for Releases Requiring a Single File

Cisco IOS Release 11.2(10)P or later and Cisco IOS Release 11.3(2)T (future) or later support bundled modem code for the 12-port module. This modem code image is in a single-file format and consists of the following files:

  • Modem controller firmware, which is stored in the modem card Flash memory. This firmware does not have to be downloaded after power cycles or software reloads.
  • DSP software, which runs from modem RAM. This software needs to be downloaded from boot Flash memory after power cycles or software reloads.

Modem code can reside on the access server in two locations: one version is bundled with Cisco IOS software, and another version can exist in boot Flash memory. This modem code residing in boot Flash memory is a single file comprised of the modem firmware image combined with the DSP software image.

After power on, Cisco IOS software uses its bundled modem code file or the existing modem code file in boot Flash memory to automatically update the DSP software. This means that after you install or replace a 12-port module, you can allow the system software to download compatible DSP software and then proceed directly to the configuration steps (page 29). However, because you can control the version of modem code used by the modems, the remainder of this section provides information about how Cisco IOS software processes modem code updates and how you can load a different version than the one automatically selected.


Note      Systems running Cisco IOS Release 11.2(10)P or later or Cisco IOS Release 11.3(2)T (future) or later have bundled modem code and do not require download of the modem code shipped on the disk with the module. However, the disk may contain a later version of modem code than the version bundled with Cisco IOS software. You have the option of downloading this version and overriding the version selected by Cisco IOS software.


When you install a new 12-port module, Cisco IOS software examines the following versions of modem code:

  • Cisco IOS bundled modem code
  • Firmware in modem Flash memory
  • Any mapped modem code file in boot Flash memory

Then, Cisco IOS software ensures that the system uses matching DSP software and modem firmware—which may include overriding the current firmware on the modem. In some circumstances you may decide to manually update the modem code after the automatic download process completes.

Deciding on an Update Strategy

Because of the possibility of multiple versions of modem code and the way Cisco IOS software processes these versions, Cisco suggests that you decide between the following two strategies:

  • Always allow Cisco IOS software to use the bundled modem code (quick install approach)
  • Always control the version of modem code used by the modules, independent of Cisco IOS selections

To help with the decision, Figure 5 shows a hypothetical release process. We recommend that you use the modem code bundled with Cisco IOS software because it is the easier strategy and enables you to take advantage of new modem code whenever you upgrade your Cisco IOS software. You can also control the modem code move directly—use the copy command as discussed later.


Figure 5   Release Timeline for Cisco IOS Software and Modem Code


Modem Code Upgrade Scenarios

When you add or replace a 12-port module, Cisco IOS software handles the initial modem code download. However, you may decide to download a different version from the one selected by software. Because Cisco IOS software maps modem code (either the bundled Cisco IOS version or a boot Flash memory version) to a given slot/port and not the physical modem, Cisco IOS software will automatically load the modem code mapped to the previous module (for more information, see the description of mapping in Table 4). Whenever Cisco IOS software recognizes the modem code as invalid, it uses the bundled version.

Table 2 provides scenarios that occur when you upgrade Cisco IOS software or modem code.

Table 2   Modem Code Scenarios—Cisco IOS Software or Modem Code Upgrades

No. Scenario Update Process

1

You update Cisco IOS software, and you decide to use the version of modem code selected by Cisco IOS software.

  • Update Cisco IOS software.
  • No further action needed—Cisco IOS software automatically downloads either its bundled version or a mapped version from boot Flash memory.1

2

You update Cisco IOS software, and you decide not to use the modem code selected by Cisco IOS software.

  • Update Cisco IOS software.
  • Copy the desired version of modem code file to boot Flash memory, then copy that file to the integrated modems on the 12-port module.

See "Using the Modem Code from an External File,".

3

The modems are running a version of modem code from boot Flash memory that is different than the version bundled with Cisco IOS software. You decide to revert to the bundled version.

  • Use the Cisco IOS command copy system:/ucode/filename modem (or, for Cisco IOS releases earlier than 11.3AA or 12.0, copy ios-bundled modem). To view a list of microcode filenames, use the dir system:/ucode command.

See "Using the Modem Code Bundled with Cisco IOS Software,".

4

Cisco releases new modem code, which is a later version than the version currently running on the modems. You decide to use Cisco's newest modem code.2

  • Copy the desired version of modem code file to boot Flash memory, then copy that file to the integrated modems on the 12-port module.

See "Using the Modem Code from an External File,".

1In part, Cisco IOS software bases this decision on the last copy command issued. For more details about mapping, see Table 4.

2Cisco ships new modem code on a disk packed with the 12-port module.

Figure 6 shows a location on the release timeline where updates might take place, and Table 3 explains the resulting versions of Cisco IOS software and modem code.

2You upgraded Cisco IOS code only; therefore, the modem code remains as Version 4 (upgraded in Step 3).

3You upgraded to the Modem Mode Version 3, which was bundled with Cisco IOS Release D.

Table 4 provides a list of terms and commands and a description of how they are used in the modem code update process.

Table 4   Modem Code Terminology

Term Description

Modem firmware

Modem controller firmware that resides in modem Flash memory.

DSP software

DSP controller software that resides in modem RAM. Cisco IOS software transfers a version of DSP software to modem RAM on each reboot.

Modem code

Two images:

  • Modem controller firmware
  • DSP software

These images reside separately in the modems and as a single-file version in the access server's boot Flash memory.

System Flash memory can contain several versions of modem code: a version bundled with Cisco IOS software and multiple versions that resulted from previous copy tftp flash commands.

copy tftp flash mcom-modem-code-x.x.x.bin
command

Places a copy of the modem code in boot Flash memory.

copy flash modem command

Transfers the copy tftp flash version of modem code to the modems. This command transfers the modem firmware file to modem Flash memory and the DSP software file to modem RAM.

Maps the boot Flash memory version to the modems.

copy system:/ucode/filename modem command
(or, for Cisco IOS releases earlier than 11.3AA or 12.0, copy ios-bundled command

Instructs the modems to use the version of modem code bundled with Cisco IOS software. This command does not affect any existing versions of modem code that reside in boot Flash memory.

After one such command, future Cisco IOS upgrades will potentially result in the downloading of new Cisco IOS bundled firmware to the modems. (If the new Cisco IOS image contains the same modem code as the old one, no new code will be downloaded to the modems.)

Maps the bundled Cisco IOS software version to the modems.

Mapping

The copy commands map a specific version of modem code to a group of modem slots/ports. The copy system:/ucode/filename modem (or copy ios-bundled modem) command maps the slots/ports to the bundled version, and the copy flash modem command maps the slots/ports to a specific modem code file located in boot Flash memory. Cisco IOS software uses the mapping to determine which version of modem code should be downloaded to the modems. If Cisco IOS software finds no mapping or invalid mapping, it downloads the bundled version.

Using the Modem Code from an External File

Use the procedures in this section to transfer modem code from Cisco Connection Online (CCO) to the integrated modems on the 12-port module. The procedure consists of the following tasks:

  • Download the modem code to a TFTP server
  • Copy the modem code from the TFTP server to the modems

Downloading Modem Code to a TFTP Server

You can download the single file (mcom-modem-code-x.x.x.bin) to a TFTP server on your LAN two ways:

  • Using an Internet browser
  • Using a traditional FTP application
Download Modem Code to a TFTP Server—Method 1, Use an Internet Browser

Log in to Cisco's Software Center at the following URL to download the modem code file. You must log in as a Cisco registered user. (If you are not a registered user, note that Cisco provides modem code on a disk when are updates are necessary. This disk is shipped with the 12-port module.)

After downloading to your desktop computer, you must transfer it to a TFTP server on your network using an FTP application.

Alternatively, you can access Cisco at http://www.cisco.com, login, and take the following path to the file:

  • Service and Support
  • Software Center
  • Access Products
  • Cisco AS5200 Series Software
  • Download Microcom 56K Modem Firmware
Download Modem Code to a TFTP Server — Method 2, Use a Traditional FTP Application

Take the following steps to download the modem code file from Cisco's FTP server using an FTP client application. These steps assume that you want to download both the modem firmware and the DSP software.


Note      The directory path leading to the 56K images on cco.cisco.com is subject to change without notice. If you cannot access the files using an FTP application, use Download Method 1.

total 596
-r--r--r-- 1 377112 Jul 10 18:08 mcom-modem-code-3.1.30.bin
server% pwd
/auto/tftpboot

Step 9   If you have not already done so, transfer this file to a local TFTP server that your Cisco AS5200 can access.


Note      In some cases, Cisco ships modem software on a disk. To use this software, first upload the software to your TFTP server, then download the software to the modem using the method described in the next section "Copying the Modem Code File from a Local TFTP Server to the Modems."

If you loaded Cisco IOS software from a feature pack CD using Router Software Loader (RSL), note that the CD contains a TFTP server program for PCs using Windows 95. Run the server program from the directory where you installed the RSL program. Remember to set the Root directory to the directory where the Cisco AS5200 56K modem code is located. RSL is also available on CCO in the software library in the Access Products section.


Copying the Modem Code File from a Local TFTP Server to the Modems

The procedure for copying the modem code file from your local TFTP server to the access server boot Flash memory is a two-step process. First, transfer the code to the access server. Then, transfer the code to the modems.

These two steps are performed only once. After you copy the modem code file into boot Flash memory for the first time and map that file to a specific modem using the copy bootflash modem command, you do not have to perform these steps again. Because the DSP software runs from modem RAM, the Cisco IOS software must automatically copy the DSP software to each modem each time the access server power cycles.


Note      A list of download failure reasons and recommended actions is provided in the section "Download Failure Reasons and Recommended Actions."



Step 1   Copy the modem code file from your TFTP server to the access server's boot Flash memory using the copy tftp bootflash command. Cisco IOS software prompts you with a sequence of questions such as name/address of the TFTP server and the filename to be copied. Answer all of the prompts according to your configuration. The following example shows a typical download.

5200# copy tftp bootflash

Note      On the display, notice that the command copies the concatenated modem code file, mcom-modem-code-3.1.30.bin. When the DSP software and modem firmware download is complete, the display reports the modem firmware component, MNPClass10K56flexModemRev3.1.30/85, was downloaded to the modems.


If you want to verify that the DSP software and modem firmware copied to the modems, use the show modem version command. In this example, modems 2/12 through 2/23 are loaded with the modem controller firmware and DSP software:

5200# show modem version

number_of_modems= 12, option_bits= 1,
rev_num= 03.00, vendor_model_number= 02,
vendor_banner= Microcom MNP10 K56 Modem

Now the modems are equipped with code. The modems are configured to transmit at speeds up to 56 kbps. Each time the access server is power cycled, Cisco IOS software automatically loads the modems with the modem code in boot Flash memory. If you erase the modem code file from boot Flash memory, the Cisco IOS default modem code (that is, the bundled modem code) will be automatically downloaded to the modem.

Using the Modem Code Bundled with Cisco IOS Software

If you already have a version of modem code in the Flash memory on your access server, and you upgrade to a Cisco IOS release that includes newer modem firmware, only the modems that are mapped to the bundled Cisco IOS version are updated. In order to set the modem firmware mapping to the firmware version bundled with Cisco IOS software, enter the following command:

5200# copy system:/ucode/filename modem

Note      For Cisco IOS releases earlier than 11.3AA or 12.0, use the copy ios-bundled modem command.



Note      This command does not affect any existing modem code that resides in boot Flash memory in case you later want to revert to it. If you decide to delete the code from boot Flash memory, remember that all files in boot Flash memory will be deleted, therefore save and restore any important files (for example, the Cisco IOS software image).


As a result of the copy system:/ucode/filename modem (or copy ios-bundled modem) command, future Cisco IOS upgrades will potentially result in the mapping of new Cisco IOS bundled firmware to the modems. (If the new Cisco IOS image contains the same modem code as the old one, no new code will be downloaded to the modems.)


Note      To determine the version of modem code bundled with your Cisco IOS software, refer to the Cisco IOS release notes shipped with the chassis.


Download Failure Reasons and Recommended Actions

During the DSP download process, you may receive an error message if the download fails. See Table 5.

%%ERROR: NVRAM table is bad. Use Copy command to set DSP filename.

There is a NVRAM table problem.

Reissue the copy tftp bootflash command and copy the DSP file again.

%%ERROR: NVRAM is bad, Report this as a problem.

The NVRAM is not functioning properly.

Try power cycling the router to fix the problem.

%%ERROR: Ran out of Memory, Install more memory.

The system software needs more memory to complete the copy operation.

Install additional memory.

Erase Boot Flash Memory and Restore the Boot Image

The boot Flash memory in your Cisco AS5200 may not have the available space to accept the additional 56K images or files. If you experience this, you must erase the entire boot Flash memory followed by restoring the boot image before performing the necessary 56K copy operations. Because the Cisco AS5200's Flash file system does not allow individual files to be erased from boot Flash memory, you must erase the entire contents of boot Flash memory at one time. To do this, refer to Table 6.


Do not proceed with erasing your boot Flash memory unless you have a back up of your boot image on your TFTP server.

Table 6   Erasing Boot Flash Memory and Restoring the Boot Image

Task Command
Step 1. If you have not already done so, upload your current boot image to a local TFTP server. The contents of the boot Flash memory is displayed and the system software prompts you for the source filename to be copied.

copy bootflash tftp

Step 2. Erase the entire contents of the boot Flash memory.

erase bootflash

Step 3. Copy the boot image from your local file server to the Cisco AS5200's boot Flash memory. Specify the destination filename that was copied in Step 1.

copy tftp bootflash

Cisco Connection Online (CCO) is Cisco Systems' primary, real-time support channel. Maintenance customers and partners can self-register on CCO to obtain additional information and services.

Available 24 hours a day, 7 days a week, CCO provides a wealth of standard and value-added services to Cisco's customers and business partners. CCO services include product information, product documentation, software updates, release notes, technical tips, the Bug Navigator, configuration notes, brochures, descriptions of service offerings, and download access to public and authorized files.

CCO serves a wide variety of users through two interfaces that are updated and enhanced simultaneously: a character-based version and a multimedia version that resides on the World Wide Web (WWW). The character-based CCO supports Zmodem, Kermit, Xmodem, FTP, and Internet e-mail, and it is excellent for quick access to information over lower bandwidths. The WWW version of CCO provides richly formatted documents with photographs, figures, graphics, and video, as well as hyperlinks to related information.

You can access CCO in the following ways:
