U P D A T I N G S O F T W A R E – S T E P 4353Updating boot code over the networkAs discussed in step 1 – selecting the proper version, with either upgrade path (to Version 2.7.1B or toVersion 3.0), the boot code will be updated. At boot up time, the Magnum 6K switch identifies thatthere is a new version of the boot code and asks if the new boot code should be loaded11. The new bootcode is not loaded unless the user responds affirmatively to the question from the console port (or serialconnection)12. If the Magnum 6K switch is upgraded over the network or remotely, the boot code canbe manually updated by using the ‘upgrade’ command discussed below. This allows the boot code to beupdated without requiring access to serial port.Syntax upgrade mode=blmode=bl is a hidden option and is not visible using the help capabilities in MNS-6K.This command can be executed by accessing the switch through the console port(serial connection) or through the network (telnet to the switch.)Continue to use the network access method defined in steps 1, 2 and 3. Use the upgrade command asshown in Figure 17 and reboot the switch.Magnum6K25# upgrade mode=blThe BOOT Flash image will be replaced by the versionembedded in this application.Do you wish to upgrade the image?
