Replace A Pa-7080 Fan Tray - PaloAlto Networks PA-7000 Series Hardware Reference Manual

Replace a PA-7080 Fan Tray

The following procedure describes how to replace a PA-7080 fan tray.
If one fan on a fan tray fails, the fault LED on the fan tray will turn red. If this occurs, replace the fan tray
immediately to avoid service interruption. If two or more fans fail on one or both fan trays, the firewall
shuts down. You can replace a fan tray while the firewall is powered on; however, you must replace it
within 45 seconds and you can only replace one fan tray at a time (two total) or the thermal protection
circuit will automatically shut down the firewall.
Put the provided ESD wrist strap on your wrist ensuring that the metal contact is touching your
STEP 1 |
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
When removing a fan tray, first pull the fan tray out about 1 inch (2.5cm) and wait 10
seconds. This allows enough time for the working fans to stop spinning.
STEP 2 | Remove the replacement fan tray from the packaging and have it ready.
STEP 3 | Identify the failed fan tray by viewing the LEDs. The FAN LED on the SMC card and the FAULT
LED on the failed fan tray will both change to red in the event of a failure.
STEP 4 | Grasp both handles on the failed fan tray and gently push them outward as you slide the fan
tray toward you about 1 inch. Wait 10 seconds to allow enough time for the working fans to
stop spinning.
Pushing the handles outward does not eject the fan tray; it unlocks the tray from the
chassis. Only a small amount of pressure is required to operate the release handles.
