4.7.7 Image Select
This page provides information about the active and alternate (backup) firmware images in the device, and allows you to revert
to the alternate image. The web page displays two tables with information about the active and alternate firmware images. The
Image Select screen in Figure 4-7-7-1 appears.
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.
1. If the alternate image is active (due to 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.
2. The firmware version and date information may be empty for older firmware releases. This does
not constitute an error.
