Replace a Power Supply on a PA-850 Firewall
The PA-850 firewall has two power supplies
for power redundancy. If one power supply fails, you can replace
it without interruption as described in the following procedure.
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.

- Remove the Velcro strap that secures the AC power cord to the power supply and remove the power cord.
