For example, an OC-3c network module that is removed from slot A of the old switch fabric must be installed in slot A of the new switch fabric. Therefore, it is recommended that you label all network connections and network modules before removing them Hardware Maintenance Procedures 5-17CAUTION Make sure the replacement board is properly aligned in the slot in the next step Hardware Maintenance Procedures 5-18 Software Upgrade Instructions CHAPTER6.1 Obtaining the Software Upgrade File via Diskette Software Upgrade Instructionstar -xvf device eject deviceforeextract device Software Upgrade Instructions6.2 Performing the Software Upgrade mkdir /tftpbootmv ﬁlename /tftpboot operation upgrade ?operation upgrade 169.144.3.54ASX-200BX4.0.01.3 operation upgrade 169.144.3.54asx-scp4.0.01.3Software Upgrade Instructions Software Upgrade Instructions Reboot the switchy? y6.3 Changing between Multiple Versions of Software Software Upgrade Instructionslocalhostoperation reboot Software Upgrade InstructionsAre you sure you want to reboot this switch n? y 6.4 Using bootp to Download Software to the Switch 6.4.2 Setting Up Your bootp Server6.4.1 Overview Software Upgrade Instructions6-10 6.4.3 Adding an Entry for Your Switch in the bootptab FileSoftware Upgrade Instructions Software Upgrade Instructions 6-11The variables in the previous example are deﬁned as follows 6-12 6.4.4 Setting Up a tftpboot ServerSoftware Upgrade Instructions A.1 Adapter Hardware Troubleshooting TroubleshootingAPPENDIX A Troubleshooting Figure A.1 -
