Replace a PA-5500 Series Firewall Fan Assembly

Learn how to replace a fan assembly on the PA-5500 Series Firewall.

The PA-5500 Series firewalls have five dual-rotor fan assemblies on the rear side, making ten individual fans. When all ten fans are functioning as expected, the fan LED glows green. If any fan fails, the fan LED glows yellow.

If an individual fan fails, then the firewall software automatically determines how to manage the system temperature, whether through adjusting the speeds of the other fans or shutting down the firewall.

You can hot swap a fan assembly, but you must complete Steps 5 and 6 of the following procedure within 120 seconds to avoid downtime.

Put the provided ESD wrist strap on your wrist ensuring that the metal contact is touching your skin. Then attach (snap) one end of the ground cable to the wrist strap and remove the alligator clip from the banana clip on the other end of the ESD grounding cable. Plug the banana clip end into the ESD port located on the rear of the appliance before handling ESD sensitive hardware. For details on the ESD port location, see PA-5500 Series Firewall Back Panel.

When removing a fan assembly, first pull the fan assembly out about 1 inch (2.5cm) and wait 10 seconds. This allows enough time for the working fans to stop spinning.
Remove the replacement fan assembly from the packaging and have it ready.
Identify the fan assembly with the failed fan(s) by using the following CLI command:
```
admin@PA-5540> show system environmentals fan-tray
```
The fan assemblies are numbered 1 through 5 from left to right.
Loosen the captive screw holding the fan assembly in place.
While gripping the fan assembly handle, gently pull the fan assembly out of its slot.
Install the replacement fan by sliding it into the vacant fan slot. Tighten the captive screw by turning it clockwise until it is secure. Ensure that the fan assembly is secure by gently pulling on the handle.
Verify that the new fan assembly is operational by noting the status of the fan LED on the front panel. The fan LED shows green if all fans are working as expected. You can also view the status of the fan assemblies by entering the following command:
```
admin@PA-5540> show system environmentals fan-tray
```
To view the status of each fan in an assembly, run the following command:
```
admin@PA-5540> show system environmentals fans
```
