Replace a Power Adapter on a PA-400 Series Firewall
Remove a failed power adapter from a PA-400 Series firewall
and replace it with a new power adapter.
The PA-415, PA-415-5G, PA-440, PA-445, PA-450, PA-455, PA-455-5G, and PA-460 firewalls can
operate on one power adapter or you can install a second power adapter for power
redundancy. If two power adapters are installed and one fails, you can replace the
failed power adapter without interruption. The PA-410 can only operate on one power
adapter.
The CLI cannot be used to determine the
status of the PA-400 Series firewalls power adapter. To manually
interpret the status of the power adapter, verify that your power
cable connections are secure and that the LED on the power adapter
is on. If the LED is not illuminated even though the power cable connections
are secure, your power adapter has failed.
To avoid injury to yourself or damage to
your Palo Alto Networks® hardware or the data that resides on the
hardware, read the Product Safety Warnings.
