Reboot
1. Open the PA1's web interface.
2. Click Advanced in the menu on the left side of the window page. The "Advanced Settings" page
opens.
3. Click the Update tab.
4. Click "Reboot" and confirm with "Yes". The red LED lights up, and the green LED goes out. When
the PA1+ has finished rebooting, the red LED goes out, the green LED lights up, and the web
interface is available again.
Hard reboot
Disconnect the power, wait for a few seconds, and reconnect.
WARNING: when the red light is on or blinking, a firmware update is ongoing. DO
NOT remove the device's power supply (Ethernet cable when using PoE, power adapter
when not using PoE).
Never disconnect the power during a firmware update! Cutting off the device's power
during a firmware update (red LED on, green LED off) will damage the firmware and
render the PA1+ inoperational.
In such a case, the PA1+ will need to be returned to the vendor for resetting (special kit
required).
