These release notes describe the caveats for the Catalyst 2900 series XL modules.
These release notes contain the following topics:
The Catalyst 2900 series switches now offer a 1000BaseX module in addition to the switched 10BaseT/100BaseTX and 100BaseFX modules. The 1000BaseX module allows you to install either a short-wavelength (SX) or long-wavelength (LX/LH) Gigabit Interface Converter (GBIC). These modules can add port density and fiber-optic connectivity or high-speed uplink to a Catalyst 2900 series XL network. The 10BaseT/100BaseTX module autonegotiates the duplex and speed settings of each port to match that of the attached device. The 1000BaseX module autonegotiates the duplex mode only.
The following features are supported on the 1000BaseX module:
| Caution Autonegotiation with Gigabit Ethernet behaves differently than autonegotiation with Ethernet or FastEthernet. To avoid link configuration problems, refer to the Catalyst 2900 Series XL Enterprise Edition Software Configuration Guide for information about autonegotiation. |
You must tighten the screws while inserting the module in the switch.

.
To use the Gigabit Ethernet module (WS-X2931-XL) with a Catalyst 2900 series XL switch, ensure that the switch is running IOS version SA5 or later. For information on upgrading the switch software, see "Upgrading Your Catalyst 2900 Series XL Switch Software."
Hot swapping is not supported in this release. When inserting a module in or removing a module from a switch, power off the switch. If you insert or remove a module while the switch is powered on, restart the switch using the reload command.
This section contains a list of known problems and suggested workarounds.
Some Gigabit Interface Converters (GBICs) contain faulty data. Therefore, the GBIC information is not reliable. The software cannot detect that this is erroneous information, so it passes along the faulty data. If you select a cable based on this erroneous information, the module link will not come up. To work around this problem, select a cable based on the GBIC type printed on the label.
This section describes the procedure for upgrading your Catalyst 2900 series XL switch software by using the IOS command-line interface (CLI). To perform the steps in this section, you must have a TFTP server and a management station (such as a PC) with a CD-ROM drive. You must also access the switch management console by either of these two methods:
Follow these steps to download the new software and TFTP server application:
Step 1 Display the Cisco home page by pointing your browser to one of the following URLs:
Step 2 Log into CCO. You might need to register the first time you log in.
Step 3 To locate the software files from the home page, access the FTP site at ftp://anonymous@ftpeng.cisco.com/ftp/dsbu/beta/SA5/.
Step 4 Follow the instructions on the page to download the IOS image.
Step 5 Follow the instructions on the page to download and configure the TFTP server.
Before you can download new software to your module, you need to enter the IP address of your PC or workstation on the System Management page. If you are running the Cisco TFTP server, the PC IP address is displayed on the application title bar.
If you do not know the IP address, follow these steps to display it:
You can use the CLI to perform a TFTP transfer of the files to the switch.
The procedure that follows includes the commands to address the following issues:
Follow these steps to upgrade the switch software by using a TFTP transfer:
Step 1 If your PC or workstation cannot act as a TFTP server, copy the files to a TFTP server to which you have access.
Step 2 You can access the CLI by starting a Telnet session or by connecting to the console port via the RS-232 connector.
To start a Telnet session on your PC or workstation, enter the following command:
server% telnet switch_ip_address
Step 3 Enter privileged EXEC mode:
switch> enable
switch#
Step 4 Display the name of the current (default) image file. The following example shows the current name in italic:
switch# show boot
BOOT path-list: flash:current_image
Config file: flash:config.text
Enable Break: 1
Manual Boot: no
Step 5 If there is no file defined in the BOOT path-list, enter dir flash: to display the contents of Flash memory. The file named c2900XL-h-mz_current_version is your current image file.
Step 6 Rename the current image file to the name of the new image. This does not affect the operation of the switch.
switch# rename flash:current_image flash:new_image
Source filename [current_image]?
Destination filename [new_image]?
Step 7 Display the contents of Flash memory to verify the renaming of the file:
switch# dir flash:
Directory of flash:
-rwx 910426 Mar 06 1993 23:47:28 new_image -rwx 80971 Sep 14 1998 03:10:38 c2900XL-diag-mz-112.0.0.11-SA2
-rwx 4800 Mar 01 1993 00:04:14 html
-rwx 159 Jan 01 1970 00:00:34 env_vars
-rwx 1121 Mar 01 1993 18:46:01 config.text
Step 8 Delete the diagnostics file to make room for the new image.
The diagnostics file has a name in the following format: c2900XL-diag-mz-version_name. The string version_name depends on the switch and software you are running.
Display the diagnostics file:
switch# dir flash:c2900XL-diag-mz*
Directory of flash:
-rwx 80971 Sep 14 1998 03:10:38 c2900XL-diag-mz-112.0.0.11-SA2
Delete the diagnostics file:
Switch# del flash:c2900XL-diag-mz-112.0.0.11-SA2 Delete filename [c2900XL-diag-mz-112.0.0.11-SA2]? Delete flash:c2900XL-diag-mz-112.0.0.11-SA2? [confirm] Switch#
Step 9 Enter terminal configuration mode:
switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Step 10 Disable access to the switch HTML pages:
switch(config)# no IP http server
Step 11 Change the name of the default image file:
switch(config)# boot system flash:new_image
Step 12 Return to privileged EXEC mode:
switch(config)# ^Z
Step 13 Verify that the name of the default image file is correct:
switch# show boot
BOOT path-list: flash:new_image
Config file: flash:config.text
Enable Break: 1
Manual Boot: no
HELPER path-list:
NVRAM/Config file
buffer size: 32768
Step 14 Use the name of the new image file when you copy it from the TFTP server to the Flash memory:
switch# copy tftp://server_ip_address//path/new_image flash:new_image
Source IP address or hostname [server_ip_address]?
Source filename [path/filename]?
Destination filename [flash:new_image]?
Loading /path/filename.bin from server_ip_address (via!)
[OK - 843975 bytes]
Step 15 Remove the manager software HTML files:
switch# del flash:html/*
Press the Enter key to confirm the deletion of each file. Do not press any other keys during this process.
Step 16 If you are running IOS Release 11.2(8)SA3 or later, remove the files in the Snmp directory:
switch# del flash:html/Snmp/*
Press the Enter key to confirm the deletion of each file. Do not press any other keys during this process.
Step 17 If you are running IOS Release 11.2(8)SA2 or earlier, create a directory on the switch Flash memory to be used for the HTML files:
switch# mkdir flash:html/Snmp
Make sure the "S" in "Snmp" is uppercase.
Step 18 Enter the following command to copy the HTML file from the TFTP server to the switch Flash memory:
switch# tar /x tftp://server_ip_address//path/filename.tar flash:html Loading /path/filename.tar from server_ip_address (via!)
extracting advanced.gif (2648 bytes)
extracting amber.gif (530 bytes)!
extracting bar.gif (4156 bytes)!
extracting cool.gif (530 bytes)
extracting daytona.gif (1470 bytes)
extracting duplgnd.gif (639 bytes)!
. . .
Depending on the TFTP server being used, you might need to enter only one slash (/) after the server_ip_address in the tar command.
Step 19 Enter terminal configuration mode:
switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Step 20 Reenable access to the switch HTTP pages:
switch(config)# IP http server
Step 21 Return to privileged EXEC mode:
switch(config)# ^Z
Step 22 Reload the new software with the following command:
switch# reload
System configuration has been modified. Save? [yes/no]:y
Proceed with reload? [confirm]
Step 23 Press Return to confirm the reload.
Your Telnet session ends when the switch resets.
