Aruba 5000 and 6000 Series Fan Tray Assembly Installation Notes 5
4. Check the fans to make sure all of them are working.
Once power has been restored to the fan tray, either by engaging the module to
the backplane during hot-swap or by turning on system power after a
cold-swap, the Fan Status LED should be green and you should be able to feel
significant airflow blowing from the chassis vents at each fan position.
If the fans are all working, this ends the time critical portion of the hot-swap
procedure.
If one of the fans in a newly hot-swapped fan tray does not work (yellow Fan
Status LED), allow at least three minutes for the remaining fans to cool the
switch before attempting another hot-swap replacement.
5. Secure the fan tray.
Use the screwdriver to push in and tighten both of the fastening screws on the
faceplate of the newly installed fan tray. Rotate the screws clockwise until
moderate resistance is felt, but do not over-tighten.
CAUTION—If two or more fans in the newly hot-swapped fan tray do
not work (the Fan Status LED is red or off), shut down the Mobility
Controller, replace the fan tray, and allow the switch at least five
minutes to cool before turning it back on.
