Upgrade AP3916ic

This topic describes the upgrade process that takes place for the ExtremeWireless AP3916ic access point (AP). This process takes place automatically and is described here for edification.

1. When an upgrade is required, ExtremeCloud responds to the access point (AP) check-in with an Upgrade action.
2. The Upgrade action can contain one or two software versions to which AP should upgrade. If there are two upgrade entries, one entry is for the camera. If the response requires both AP and camera software upgrades, the AP ignores the camera firmware upgrade request.
3. The AP upgrades its own firmware, just like any other cloud-enabled AP.
4. The AP reboots, and then sends a connect request.
5. When the connect request is acknowledged, the AP sends an upgrade query. ExtremeCloud determines that the AP is running the correct AP software but the wrong camera software. (Cloud-management considers the wrong camera as a failure).
6. ExtremeCloud retries the upgrade by responding with the new camera software version.
7. The AP receives the camera software version, downloads it, and then upgrades the camera to the software.
8. The AP reboots after the camera software upgrade, and then sends a connect request to the ExtremeCloud.
9. When ExtremeCloud responds to the connect request, the AP sends an upgrade query.
10. ExtremeCloud detects that the AP is running the correct versions of the AP and camera software, and then allows the AP to request configuration.
11. The AP configuration is updated and goes back into service.
