PowerConnect switches are currently at – 184.108.40.206. Upgrade is recommended to 220.127.116.11, A07. This upgrade is a two phase upgrade.
Upgrade Procedure for Switches Running 3.x.x.x Firmware
NOTE: A TFTP server must be on the network and the switch software must be accessible to the TFTP server before attempting to download the switch software by TFTP
To upgrade a switch running a 3.x.x.x version of firmware to the 18.104.22.168 version of firmware, use the procedure below. An annotated upgrade example is shown following this section.
- Back up your configuration.
e.g.: console#copy running-config tftp://10.10.10.200/myconfig.txt
- If using the serial port to perform the upgrade procedure, skip this step and begin the upgrade procedure with step
- If using telnet or ssh to perform the upgrade procedure and if the current configuration does not contain a non-default enable authentication method or enable password, configure an enable password and save the configuration. Example steps to configure an enable password are shown below:
console(config)# enable password <XXXXXX>
console# copy running-config startup-config
NOTE: It is required that either a non-default privileged exec (enable) access method or an enable password be saved in the startup config in order to access privileged exec (enable) mode after the firmware upgrade. The 22.214.171.124 firmware emulates industry standard behavior for privileged exec mode authentication over SSH and telnet. In 126.96.36.199, the default authentication list for telnet and SSH is enable NetList, which requires an enable password. If the startup configuration
being upgraded does not have a non-default enable authentication method defined (e.g. TACACS), setting an enable password allows one to access privileged exec (enable) mode after the firmware upgrade.
- Download the A.1.0.19 intermediate firmware to the switch or stack master. The following versions are available:
e.g.: console#copy tftp://10.27.9.99/PC8024vA.1.0.19.stk image
- Activate the A.1.0.19 intermediate firmware.
e.g.: console#boot system image2
- Update the boot code from the CLI after performing steps 1 through 3 above. This operation will boot the intermediate operational code from the original 3.x.x.x boot code. If the update bootcode command does not boot the switch automatically, reboot the switch and follow the rest of the upgrade procedure beginning with step 5 below. The upgrade procedure will take several minutes to complete for an individual switch and longer for a stack of switches.
e.g.: console#update bootcode
- After boot code update is complete and the interim operational firmware is loaded, log in to the switch and download the final version of 188.8.131.52 firmware. Activate the final 184.108.40.206 firmware version.
e.g.:console#copy tftp://10.27.9.99/PC8024v220.127.116.11.stk image
- Reboot the switch.
- Update Boot Code.
e.g.: console#update bootcode
NOTE: After upgrading to the 18.104.22.168 firmware, one can emulate the earlier firmware default behavior for privileged exec (enable) mode access by setting the enable authentication method to enableList.
console(config)# line telnet
console(config)# enable authentication enableList
