PA-5200 Series firewalls have either two AC
or two DC power supplies (the second power supply is for redundancy).
If one power supply fails, you can replace it without service interruption
as described in the following procedures.
Replace an AC Power Supply on a PA-5200 Series Firewall
The following procedure describes how to replace
an AC power supply.
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.
- Identify the failed power supply by viewing the power supply LED on the back of the firewall; when there is a failure the FAIL LED turns solid yellow. For details on the power supply LEDS, see Interpret the LEDs on a PA-5200 Series Firewall.
- Remove the Velcro strap that secures the AC power cord to the power supply and remove the power cord.
- Grasp the handle on the failed power supply and then simultaneously press the release lever to the left and then pull the power supply outward to remove it.
- Remove the replacement power supply from the packaging and slide it into the empty power supply slot. Push the power supply all the way in until the release lever clicks and secures the power supply.
- Connect the AC power cord to the power supply input and secure it to the power supply using the Velcro strap.
- Connect the other end of the power cord to a grounded AC power source. The new power supply automatically powers on, the OK LED turns green, the FAIL LED turns off, and the power LED (PWR 1 or PWR 2) on the front of the firewall turns green.
