Replacing the fan tray
You do not need special tools to replace the fan tray. You do not need to power down the unit when replacing
the fan tray; however, F5 Networks highly recommends that you do not leave the unit operating without a
fan tray for longer than 30 seconds.
Caution: Operating the unit without a fan tray for more than 30 seconds might cause permanent damage.
1.
Stand at the back of the platform and locate the ejector handle on the fan tray.
2. Loosen the fan tray screws by turning them counterclockwise with a Phillips screwdriver, if necessary.
Note: The screws that hold the ejector handle in place are captive and cannot be removed from the
assembly.
3. Grasp the ejector handle and rotate it downward to eject the fan tray from the system.
4.
Remove the fan tray from the system by pulling straight toward you.
5. Ensure that the handle on the new fan tray is in the down position and slide the fan tray into the fan tray
slot until the latch engages.
6.
Rotate the handle upward to fully seat the fan tray.
7. Tighten the screws into place.
The fan tray is connected to the system when you tighten the screws completely. Once seated, the fan
tray automatically powers up and begins circulating air through the chassis.
