Note | Before you use this wizard, be sure the standby supervisor management port is connected. |
To use the Software Install Wizard, perform the following steps:
The Software Install Wizard is displayed.
You must select at least one switch in order to proceed. When finished, click Next.
Click on the edit (...) button to enter image URIs and other information. You must specify at least one image for each switch in order to proceed. The total space required on the bootflash to copy the image is shown in the Required Flash Space column.
To use images that are already downloaded (the file is already on the bootflash), check the "Skip Image Download" checkbox. When you check this checkbox, you are prompted to choose an image from the bootflash for each switch being upgraded.
The table on this screen shows the active (and standby, if applicable) bootflash space on each switch, and shows the status (whether there is enough space for the new images). If any switch has insufficient space, you cannot proceed. Free space by clicking the edit button (...), or deselect the switch by going back to the first screen and unchecking the checkbox.
You must select at least one image for each switch in order to proceed.
Note | There is no limit on the number of switches you can upgrade. However, the upgrade is a serial process; that is, only a single switch is upgraded at a time. |
If you check "version check" before the upgrade process is started, a version check is done. This check provides information about the impact of the upgrade for each module on the switch. It also shows any HA-related incompatibilities that might result. A final dialog box is displayed at this stage, prompting you to confirm that this check should be performed.
Caution | If "version check" is enabled, the upgrade will proceed even if your version is newer than the version you are installing. |
Note | On hosts where the TFTP server can not be started, a warning is displayed. we show a warning, The TFTP server may not start because an existing TFTP server is running or because access to the TFTP port 69 has been denied for security reasons (the default setting on linux). In these cases, you cannot transfer files from the local host to the switch. |
Note | Before exiting the session, be sure the upgrade process is complete. The wizard will display a status as it goes along. Check the lower left-hand corner of the wizard for the status message "Upgrade Finished." First, the wizard displays the message "Success 1.2(2)" followed a few seconds later by "InProgress Polling." Then the wizard displays a second message "Success 1.2(2)" before displaying the final "Upgrade Finished." |
