Service the PA-5200 Series Firewall
Replace a Fan Tray on a PA-5200 Series Firewall
PA-5200 Series firewalls have two fan trays and each fan tray contains four fans. If one fan on a
fan tray fails, the LED on the fan tray turns red. When this occurs, immediately replace the fan
tray to avoid service interrupon. If two or more fans fail on one or both fan trays, the firewall will
shut down and you must replace the failed fan tray(s) to restore funconality.You can replace a
fan tray while the firewall is powered on but you must replace it within 45 seconds or the thermal
protecon circuit automacally shuts down the firewall.
STEP 1 | Remove the replacement fan tray from the packaging.
STEP 2 | Idenfy the failed fan tray by viewing the LEDs.
During a failure condion, the fan tray LED on the failed fan tray and the FANS LED on the
front of the firewall show red.
STEP 3 | Remove the failed fan tray.
1. Turn the two fan tray thumb screws counter-clockwise unl the screws stop.
Earlier models will have four fan-tray thumb screws rather than two. The
procedure for both setups is the same.
2. Grasp the fan tray handle and pull the tray out of the firewall.
STEP 4 | Slide the replacement fan tray into the empty fan-tray slot ensuring that the alignment
grooves on the fan tray and the fan-tray slot are aligned. Push the tray in unl it seats and
then turn the four fan-tray thumb screws clockwise to secure the tray to the firewall.
The fan tray LED turns green and if there are no other failed fans, the FAN LED on the front of
the firewall turns green.
If the thermal protecon circuit powered off the firewall due to overheang or fan failures, you
need to disconnect and reconnect power. On an AC model, disconnect both power cords, wait
five seconds, and then plug the cords back in. On a DC model, shut down the DC circuit that is
providing power to the firewall, wait five seconds, and then restore the power.
