Upgrade your FireCluster to Fireware v11.12.1
Update AP120 or AP320 Devices Managed with Gateway Wireless
Controller
Fireware v11.12.1 does NOT include firmware for AP120 or AP320 devices. To get the latest firmware, from
Gateway Wireless Controller > Summary tab, select Manage Firmware. Look for
Download to download the new firmware to your Firebox. If you have enabled automatic AP device firmware
updates in Gateway Wireless Controller, your AP devices will be automatically updated between midnight and
4:00am local time.
If you reset your Firebox to factory-default settings, the AP firmware is removed from the Firebox. From the
Gateway Wireless Controller > Summary tab, select Manage Firmware to download the latest AP firmware
to the Firebox again.
Upgrade your FireCluster to Fireware v11.12.1
Before you upgrade to Fireware v11.11 or higher, your Firebox must be running:
- Fireware XTM v11.7.5
- Fireware XTM v11.8.4
- Fireware XTM v11.9 or higher
If you try to upgrade from Policy Manager and your Firebox is running an unsupported version,
the upgrade is prevented.
If you try to schedule an OS update of managed devices through a Management Server, the
upgrade is also prevented.
If you use the Fireware Web UI to upgrade your device, you see a warning, but it is possible to
continue so you must make sure your Firebox is running v11.7.5, v11.8.4, or v11.9.x before
you upgrade to Fireware v11.11.x or higher or your Firebox will be reset to a default state.
To upgrade a FireCluster from Fireware v11.3.x to Fireware v11.9.x or higher, you must
perform a manual upgrade. For manual upgrade steps, see
You can upgrade Fireware OS for a FireCluster from Policy Manager or Fireware Web UI. To upgrade a
FireCluster from Fireware v11.10.x or lower, we recommend you use Policy Manager.
As part of the upgrade process, each cluster member reboots and rejoins the cluster. Because the cluster
cannot do load balancing while a cluster member reboot is in progress, we recommend you upgrade an
active/active cluster at a time when the network traffic is lightest.
