Learn how to replace the fan tray on a PA-3200 Series
The PA-3200 Series firewalls have one fan
tray with three fans. If one fan fails, the LED on the fan tray
turns red and the firewall generates a system log. When this occurs,
immediately replace the fan tray to avoid service interruption.
If two fans fail, the firewall will shut down and you must replace
the fan tray to restore functionality.
If one fan fails, you
can replace the fan tray while the firewall is powered on but you
must replace it within 45 seconds or the thermal protection circuit
automatically shuts down the firewall.

If the thermal protection circuit powered off the
firewall due to overheating or fan failures, you need to disconnect
and reconnect power. On an AC model, disconnect both power cords,
wait at least five seconds, and then reconnect the cords. On a DC
model, shut down the DC circuit that is providing power to the firewall,
wait at least five seconds, and then restore the power.
