Replace a PA-7050 Fan Tray
The following procedure describes how to replace a PA-7050 fan tray. There are two PA-7050
fan tray models: the first-generation PA-7050-FAN, which is one fan tray model that you can
install in the left or right fan tray slot, and the second-generation fan trays, which has a left and
right model. The left fan tray is labeled PA-7050-FANTRAY-L-A and the right fan tray is labeled
PA-7050-FANTRAY-R-A. The PA-7050-FANTRAY-R-A also contains the air filter. The procedure
to replace both models is similar.
On a PA-7050 firewall that has the
tray is located at the top of the firewall and the right fan tray (and air filter) are located at
the bottom.
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.
The second-generation fan trays provide more cooling capacity than the first-generation
fan trays and are required if you install certain hardware components. For details, see the
system and hardware requirements in

STEP 1 |
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
.
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 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.
