Replace A Fan Tray On A Pa-5200 Series Firewall - PaloAlto Networks PA-5200 Series Hardware Reference Manual

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
interruption. 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 functionality.You can replace a 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.
STEP 1 | Remove the replacement fan tray from the packaging.
STEP 2 | Identify the failed fan tray by viewing the LEDs.
During a failure condition, the fan tray LED on the failed fan tray and the FANS LED on the front of the
firewall show red.
Remove the failed fan tray.
STEP 3 |
1. Turn the two fan tray thumb screws counter-clockwise until 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 until 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 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 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.
