1.Click “Activate Alternate Image.“
2.Click “OK“ to complete firmware selection.
Figure 5-3. The Firmware Selection screen.
Parameter Description
•Activate Alternate Image: Click to use the alternate image. This button may be disabled depending on system state.
•Cancel: Cancel activating the backup image. Navigates away from this page.
•Image: The flash index name of the firmware image. The name of primary (preferred) image is image, the alternate image is named image.bk.
•Version: The version of the firmware image.
•Date: The date when the firmware was produced.
NOTE: In case the active firmware image is the alternate image, only the “Active Image“ table is shown. In this case, the Activate Alternate Image button is also disabled.
NOTE: If the alternate image is active (because of a corruption of the primary image or by manual intervention), uploading a new firmware image to the device will automatically use the primary image slot and activate this.
NOTE: The firmware version and date information may be empty for older firmware releases. This does not constitute an error.
