OAW-IAPs joining the network need to synchronize their software with the version running on the Virtual Controller,

and if the new OAW-IAP belongs to a different class, the image file for the new OAW-IAP is provided by OmniVista

3600. If OmniVista 3600 does not have the appropriate image file, the new AP will not be able to join the network.

The Virtual Controller communicates with the OmniVista 3600 server if OmniVista 3600 is configured. If

OmniVista 3600 is not configured on the OAW-IAP, the image is requested from the Image server.

Image Management Using Cloud Server

If the multi-class AOS-W Instant software network is not managed by OmniVista 3600, image upgrades can be done

through the cloud-based image check feature. When a new OAW-IAP joining the network needs to synchronize its

software version with the version on the Virtual Controller and if the new OAW-IAP belongs to a different class, the

image file for the new OAW-IAP is provided by the cloud server.

Upgrading anOAW-IAP Using Automatic Image Check

You can upgrade an OAW-IAP by using the automatic image check feature. The Automatic image checks are

performed once after the AP boots up and every week thereafter.

If the image check locates a new version of the AOS-W Instant software on the image server, a New version

available link appears at the top right corner of the Instant UI.

If OmniVista 3600 is configured, the automatic image check is disabled.

To check for a new version on the image server in the cloud:

1. Go to Maintenance>Automatic>Check for New Version. After the image check is completed, one of the

following messages appears:

n No new version available — If there is no new version available.

n Image server timed out — Connection or session between the image server and the OAW-IAP is timed out.

n Image server failure — If the image server does not respond.

n A new image version found — If a new image version is found.

2. If a new version is found, the Upgrade Now button becomes available and the version number is displayed.

3. Click Upgrade Now.

The OAW-IAP downloads the image from the server, saves it to flash and reboots. Depending on the progress

and success of the upgrade, one of the following messages is displayed:

n Upgrading — While image upgrading is in progress.

n Upgrade successful — When the upgrading is successful.

n Upgrade failed — When the upgrading fails.

If the upgrade fails and an error message is displayed, retry upgrading the OAW-IAP.

Upgrading to a New Version Manually

If the automatic image check feature is disabled, you can use obtain an image file from a local file system or from a

TFTPor HTTP URL. To manually check for a new firmware image version and obtain an image file:

1. Navigate to Maintenance>Firmware. The Firmware window is displayed.
