Upgrading firmware on a local switch
This section provides overviews and examples of upgrading firmware in a variety of ways.
Preparing for a firmware download
To prepare for a firmware download, perform the tasks listed in this section. In the unlikely event of a
failure or timeout, you will be able to provide your switch support provider the information required to
troubleshoot the firmware download.
1. Verify the current firmware version. Refer to Obtaining the firmware version on page 115 for details.
2. Download the firmware package from the Brocade website to an FTP server.
3. Decompress the firmware archive. Refer to
Obtaining and decompressing firmware on page 112.
4. Decide on a migration path. Check the connected devices to ensure firmware compatibility and that
any older versions are supported. Refer to the “Network OS Compatibility” section of the Network
OS Release Notes for the recommended firmware version.
5. In a modular system, if you are to download firmware from a file server, verify that the management
ports on both MMs are connected to the firmware file server.
6. Back up your switch configuration prior to the firmware download. Refer to Installing and
Maintaining Firmware on page 111 for details.
7. For additional support, connect the switch to a computer with a serial console cable. Ensure that all
serial consoles and any open network connection sessions, such as Telnet, are logged and
included with any trouble reports.
8. Enter the copy support command to collect all current core files prior to executing the firmware
download. This information helps to troubleshoot the firmware download process in the event of a
problem.
9. Enter the clear logging raslogcommand to erase all existing messages in addition to internal
messages.
Connecting to the switch
When you upgrade firmware in default mode, you connect to the switch through the management IP
address. Modular switches have one management IP address for the chassis and separate IP
addresses for each management module. To upgrade both management modules, you can either
connect to the chassis management IP address or to the IP address of the active management
module. If you want to upgrade a single management module only, you must connect to the IP
address of that management module and run the firmware download command in manual mode. In
manual mode, only the local management module is upgraded.
Use the show system command to display the management IP address for the chassis.
