Replace A Pa-7000 Series Air Filter - PaloAlto Networks PA-7000 Series Hardware Reference Manual

8. Verify that the fan tray is operational by noting the status of the fan tray LEDs and the FAN LED
on the SMC (slot 6). The Fault LED on the fan tray turns off, the Power LED on the fan tray
illuminates green, and the FAN LED on the SMC changes from red to green. You can view the
status of the fan trays by running the CLI command:
admin@PA-7080> show system environmentals fan-tray
To view the status of each fan on a fan tray, run the following command:
admin@PA-7080> show system environmentals fans
Note: The fan tray status is managed by the SMC in slot 6, so the output from the
above command will show that both fan trays are in slot S6.

Replace a PA-7000 Series Air Filter

The air filter is a critical part of the chassis cooling system and ensures that air entering the chassis does
not contain debris. Replacing the air filter is a very simple procedure that must be performed
approximately every six months depending on the environment where the firewall is located. You can
purchase replacement air filters from Palo Alto Networks or an authorized reseller.
Note: The firewall does not generate a system log that indicates that the air filter
has been removed or that it needs cleaning so you must periodically inspect the
filter. Do not attempt to clean and reuse the air filter.
1. Read "Cautions and Warnings Related to Working with the Hardware" on page 89.
2. 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
one of the ESD ports located on the front of the chassis before handling ESD sensitive hardware.
For details on the ESD port location, see "PA-7050 Front Panel (AC)" on page 6 or "PA-7080
Front Panel (AC)" on page 13.
3. Grasp the air filter handle(s) and gently pull the air filter out to unsnap it from the mount point (ball
joint) located at the back of the filter and then remove the filter. Figure 67 shows how to remove
the PA-7050 air filter and Figure 68 shows how to remove the PA-7080 air filter.
Note: The filter is secured to the chassis using ball joints located at the back of the
filter. The PA-7050 filter has two handles at the front and one ball joint at the back
and the PA-7080 filter has one handle at the front and two ball joints at the back.
4. Slide the new filter into the chassis as shown in the figures, ensuring that the filter is aligned with
the slide rails and that it is facing the correct position. The grid side of the filter faces the center of
the chassis.
5. Push the filter in until the rear ball joint(s) snap into place.
