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 a two or more fans fail on one or both fan trays, the
firewall will shut 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.

Replace a PA-7050 Fan Tray

1. Read the 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.
WARNING: When removing a fan tray, first pull the fan tray out about 2 inches and wait
5 seconds. This allows enough time for the working fans to stop spinning.
3. Remove the replacement fan tray from the packaging and have it ready.
4. Identify the failed fan tray by viewing the LEDs. The red fan LED on the SMC card and the red
fault LED on the failed fan tray will both turn red in the event of a failure.
5. Turn the top and bottom fan tray thumb screws counter-clockwise until the screws stop. This will
move the latches to the open position in preparation for the fan tray removal as shown in Figure 64.
