Updating Node Device Firmware

To update the firmware on both devices in an HA configuration, you must initiate the process from the active node.

Note:

To ensure the devices resume their current node roles after the firmware update, do not disconnect the power supply during the update process.
To update the firmware on a single device, you must first remove the HA configuration. For details, see Removing HA Configuration.

Log on to QNE on the active node.
Go to Control Panel > System > System Update > Firmware Update.
Click Check for Update.

Tip:
You can also update the firmware manually. For details, see "Updating the Firmware Manually" in the QNE User Guide.
1. The active node copies the new firmware to the standby node.
2. The active node requests the standby node to perform a firmware update.
3. The HA link is severed and data synchronization is halted.
4. The standby node updates the device firmware and restarts.
  
  Note:
  If the update process times out on the standby node, the firmware update is canceled on both devices and the HA link is reestablished.
5. The active node confirms the standby node has successfully updated the device firmware and restarted.
6. The active node updates the device firmware and restarts.
  
  Note:
  If the update process times out on the active node, the firmware update is canceled on both devices and the HA link is reestablished.
7. The active and standby nodes reconnect and reestablish the HA link.
