Staging an Image

From the Resource > Images page, you can select an image and click the Stage button to stage the image onto one or more physical or virtual devices or Virtual Network Functions (VNF). You can stage an image onto a single device or multiple devices on a per-site basis or across all sites of a tenant.

From the Stage Image: Select Devices page, you can choose to stage an image, and also to either run the staging immediately or at a scheduled time.

The Stage option is especially useful if you are using a low-bandwidth connection. On low-bandwidth connections, manually staging an image prior to deploying the image helps prevent the image deployment from timing out because of a slow connection. On high-bandwidth connections, you can choose to stage the image along with the image deployment.

To deploy a device image onto devices:

  1. Select Resource > Images.

    The Images page appears.

  2. Select the device image to be staged on the device and click the Stage button.

    The Stage Image: Select Devices page appears and a list of compatible devices (CPE and VNF) for the selected image is retrieved and displayed with their associated information in the page. See Table 1 for the details of the device.


    The Deploy button is enabled only for device images.

  3. Select one or more devices onto which the device image needs to be staged and schedule a date and time for image staging.

Stage Expiry Time

Specify the maximum number of seconds CSO must wait for an image staging to be complete. If staging is not complete in the specified time, the operation times out. You can use this setting to configure a longer timeout for image staging over low-bandwidth connections. The default is 7200 seconds.

Choose Staging Time

Run now

Select this option if you want to stage the image onto the device immediately.

Schedule at a later time

Select this option to schedule the image staging for a later date and time, and specify the date and time when you want the image to be staged.
